MOAR03	LOFAR2.0: Station Control Upgrade	controls, hardware, TANGO, software	31
	T. Juerges, J.J.D. Mol, T. Snijder ASTRON, Dwingeloo, The Netherlands
	After 10 years of operation, the LOw Frequency ARray (LOFAR) telescope is undergoing a significant hardware upgrade towards LOFAR2.0. The hardware upgrade will enable the phased array telescope to observe at 10-90 MHz and at 120-240 MHz frequencies at the same time. With the upgrade comes also the chance to review LOFAR’s Control System and to make it ready for the next 10 years of operation at the forefront of low-frequency astronomy. In this work we will give a brief overview over the LOFAR telescope with its more than 50 geographically distributed receiver locations (LOFAR Stations), and the software that is necessary to monitor and control every single one of them. We will then describe the Station Control architecture, with its software design and how it is implemented in Python 3 with Tango Controls, OPC-UA clients and deployed as Docker containers. Lastly we will report on the successful use of open stack software like ELK and, Grafana.

	The Extremely Large Telescope (ELT) is a 39m optical telescope under construction in the Chilean Atacama desert. The design is based on a five-mirror scheme, incorporating Adaptive Optics (AO). The primary mirror consists of 798 segments with 1.4m diameter. The main control challenges can be identified in the number of sensors (~25000) and actuators (~15000) to be coordinated, the computing performance and small latency required for phasing of the primary mirror and the AO. We focus on the design and implementation of the supervisory systems and control strategies. This includes a real time computing (RTC) toolkit to support the implementation of the AO for telescope and instruments. We will also report on the progress done in the implementation of the control software infrastructure necessary for development, testing and integration. We identify a few lessons learned in the past years of development and major challenges for the coming phases of the project.

MOBR02	Control, Readout and Monitoring for the Medium-Sized Telesopes in the Cherenkov Telescope Array	controls, software, hardware, monitoring	77
	U. Schwanke, G. Spengler HU Berlin, Berlin, Germany D. Melkumyan, T. Murach, T. Schmidt, P. Wagner DESY Zeuthen, Zeuthen, Germany I. Oya CTA, Heidelberg, Germany
	The Cherenkov Telescope Array (CTA) is the next-generation ground-based gamma-ray observatory. Its design comprises close to 100 imaging atmospheric Cherenkov telescopes deployed at a southern (Paranal, Chile) and a northern (La Palma, Canary Islands, Spain) site. The inclusion of various array elements, like Large-Sized, Medium-Sized and Small-Sized Telescopes, instruments for atmosphere monitoring, etc, into the Array Control and Data Acquisition System (ACADA) poses a particular challenge which is met by an appropriate software architecture and a well-defined interface for array elements. This conference contribution describes exemplarily how the interface is implemented for the Medium-Sized Telescopes (MSTs, 12m diameter). The implementation uses the ALMA Common Software (ACS) as a framework for software applications facilitating the readout and control of telescope subsystems like the drive system or the pointing camera; the communication with subsystems takes advantage of the OPC UA protocol. It is also discussed what technologies (e.g. data bases) are used for the acquisition and storage of telescope-specific monitoring data.

MOPV005	Towards a New Control System for PETRA IV	controls, hardware, timing, software	108
	R. Bacher, T. Delfs, D. Mathes, T. Tempel, T. Wilksen DESY, Hamburg, Germany
	At DESY, an upgrade of the PETRA III synchrotron light source towards a fourth-generation, low emittance machine PETRA IV is currently being actively pursued. The basic concept of the control system of PETRAIV is to exploit synergies between all accelerator facilities operated by DESY. The key figures of PETRAIV’s new accelerator control system include the DOOCS control system framework, high-end MTCA.4 technology compliant hardware interfaces for triggered, high-performance applications and hardware interfaces for conventional slow-control applications compliant with industrial process control standards such as OPC UA, and enhanced data acquisition and data storage capabilities. In addition, the suitability of standards for graphical user interfaces based on novel Web application technologies will be investigated. Finally, there is a general focus on improving quality management and quality assurance measures, including proper configuration management, requirements management, bug tracking, software development, and software lifetime management. The paper will report on the current state of development.

MOPV017	CERN SCADA Systems 2020 Large Upgrade Campaign Retrospective	SCADA, controls, operation, software	156
	L.G. Goralczyk, A.F. Kostopoulos, B. Schofield, J-C. Tournier CERN, Geneva, Switzerland
	In this paper we report the experience from a large-scale upgrade campaign of SCADA control systems performed during the second LHC Long Shutdown at CERN. Such periodical upgrades are dictated by the ever evolving SCADA WinCC OA system and the CERN frameworks evolution used in those control systems. These upgrades concern: accelerator control systems, e.g. quench protection system, powering interlocks, magnet alignment; control systems devoted to accelerator facilities such as cryogenics, vacuum, gas… and other global technical infrastructure systems as well as the CERN electrical distribution system. Since there are more than 200 SCADA projects covering the CERN accelerator complex and technical infrastructure, any disruption requires careful coordination, planning and execution with process owners. Having gained experience from previous campaigns and reaching a new level of automation we were able to make visible improvements by shortening the required time and reducing the personnel required. Activities, lessons learned and further improvements are presented as well as a comprehensive statistical insight of the whole campaign.

	OPC Unified Architecture (OPC UA) is an open platform independent communication architecture for industrial automation developed by the OPC Foundation. Its key characteristics include a rich service-oriented architecture, enhanced security functionality and an integral information model, allowing to map complex data into an OPC UA namespace. With its increasing popularity in the industrial world, OPC UA is an excellent strategic choice for integrating a wealth of different COTS devices and controllers into an existing control system infrastructure. The security functions extend its application to larger networks and across firewalls, while the support of user-defined data structures and fully symbolic addressing ensure flexibility, separation of concerns and robustness in the user interfaces. In an international collaboration, a generic OPC UA support for the EPICS control system toolkit has been developed. It is used in operation at several facilities, integrating a variety of commercial controllers and systems. We describe design and implementation approach, discuss use cases and software quality aspects, report performance and present a roadmap of the next development steps.

MOPV030	Application of EPICS Software in Linear Accelerator	software, operation, rfq, controls	193
	Y.H. Guo, H.T. Liu, B.J. Wang, R. Wang, N. Xie IMP/CAS, Lanzhou, People’s Republic of China
	The institute of modern physics (IMP) has two sets of linear accelerator facilities, they are CAFe (China ADS front-end demo linac) and LEAF (Low Energy Accelerator Facility). The Main equipment of LEAF facility consists of ion source, LEBT (Low Energy Beam Transport), RFQ (Radio Frequency Quadrupole) and some experiment terminals. Compare with LEAF, CAFe equipment has more and adds MEBT (Middle Energy Beam Transport) and four sets of superconducting cavity strings at the back end of RFQ. In the process of commissioning and running linac equipment, The EPICS Archiver application and Alarm system are used. According to the refined control requirements of the facility sites, we have completed the software upgrade and deployment of the archiver and alarm systems. The upgraded software systems have made the operation of linac machines more effective in term of monitoring, fault-diagnostic and system recovery, and becomes more user-friendly as well.

MOPV031	The Deployment Technology of EPICS Application Software Based on Docker	EPICS, controls, software, network	197
	R. Wang, Y.H. Guo, B.J. Wang, N. Xie IMP/CAS, Lanzhou, People’s Republic of China
	StreamDevice, as a general-purpose string interface device’s Epics driver, has been widely used in the control of devices with network and serial ports in CAFe equipment. For example, the remote control of magnet power supply, vacuum gauges, and various vacuum valves or pumps, as well as the information reading and control of Gauss meter equipment used in magnetic field measurement. In the process of on-site software development, we found that various errors are caused during the deployment of StreamDevice about the dependence on software environment and library functions, which because of different operating system environments and EPICS tool software versions. This makes StreamDevice deployment very time-consuming and labor-intensive. To ensure that StreamDevice works in a unified environment and can be deployed and migrated efficiently, the Docker container technology is used to encapsulate its software and its application environment. Images will be uploaded to an Aliyun private library to facilitate software developers to download and use.

MOPV041	Modernisation of the Toolchain and Continuous Integration of Front-End Computer Software at CERN	software, framework, controls, network	242
	P. Mantion, S. Deghaye, L. Fiszer, F. Irannejad, J. Lauener, M. Voelkle CERN, Geneva, Switzerland
	Building C++ software for low-level computers requires carefully tested frameworks and libraries. The major difficulties in building C++ software are to ensure that the artifacts are compatible with the target system’s (OS, Application Binary Interface), and to ensure that transitive dependent libraries are compatible when linked together. Thus developers/maintainers must be provided with efficient tooling for friction-less workflows: standardisation of the project description and build, automatic CI, flexible development environment. The open-source community with services like Github and Gitlab have set high expectations with regards to developer user experience. This paper describes how we leveraged Conan and CMake to standardise the build of C++ projects, avoid the "dependency hell" and provide an easy way to distribute C++ packages. A CI system orchestrated by Jenkins and based on automatic job definition and in-source, versioned, configuration has been implemented. The developer experience is further enhanced by wrapping the common flows (compile, test, release) into a command line tool, which also helps transitioning from the legacy build system (legacy makefiles, SVN).

MOPV049	Standardizing a Python Development Environment for Large Controls Systems	controls, network, GUI, software	277
	S.L. Clark, P.S. Dyer, S. Nemesure BNL, Upton, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Python provides broad design freedom to programmers and a low barrier of entry for new software developers. These aspects have proven that unless standardized, a Python codebase will tend to diverge from a common style and architecture, becoming unmaintainable across the scope of a large controls system. Mitigating these effects requires a set of tools, standards, and procedures developed to assert boundaries on certain aspects of Python development – namely project organization, version management, and deployment procedures. Common tools like Git, GitLab, and virtual environments form a basis for development, with in-house utilities presenting their capabilities in a clear, developer-focused way. This paper describes the necessary constraints needed for development and deployment of large-scale Python applications, the function of the tools which comprise the development environment, and how these tools are leveraged to create simple and effective procedures to guide development.

TUBL05	Pysmlib: A Python Finite State Machine Library for EPICS	EPICS, controls, software, operation	330

	In the field of Experimental Physics and Industrial Control Systems (EPICS), the traditional tool to implement high level procedures is the Sequencer. While this is a mature, fast, and well-proven software, it comes with some drawbacks. For example, it’s based on a custom C-like programming language which may be unfamiliar to new users and it often results in complex, hard to read code. This paper presents pysmlib, a free and open source Python library developed as a simpler alternative to the EPICS Sequencer. The library exposes a simple interface to develop event-driven Finite State Machines (FSM), where the inputs are connected to Channel Access Process Variables (PV) thanks to the PyEpics** integration. Other features include parallel FSM with multi-threading support and input sharing, timers, and an integrated watchdog logic. The library offers a lower barrier to enter and greater extensibility thanks to the large ecosystem of scientific and engineering python libraries, making it a perfect fit for modern control system requirements. Pysmlib has been deployed in multiple projects at INFN Legnaro National Laboratories (LNL), proving its robustness and flexibility. * L. R. Dalesio, M. R. Kraimer, and A. J. Kozubal.

TUBR01	Nominal Device Support (NDSv3) as a Software Framework for Measurement Systems in Diagnostics	controls, EPICS, software, hardware	337
	R. Lange ITER Organization, St. Paul lez Durance, France M. Astrain, V. Costa, D. Rivilla, M. Ruiz UPM-I2A2, Madrid, Spain J. Moreno, D. Sanz GMV, Madrid, Spain
	Software integration of diverse data acquisition and timing hardware devices in diagnostics applications is very challenging. While the implementation should manage multiple hardware devices from different manufacturers providing different applications program interfaces (APIs), scientists would rather focus on the high level configuration, using their specific environment such as EPICS, Tango, the ITER Real-Time Framework or the MARTe2 middleware. The Nominal Device Support (NDSv3) C++ framework, conceived by Cosylab and under development at ITER for use in its diagnostic applications, uses a layered approach, abstracting specific hardware device APIs as well as the interface to control systems and real-time applications. ITER CODAC and its partners have developed NDS device drivers using both PXIe and MTCA platforms for multifunction DAQ devices, timing cards and FPGA-based solutions. In addition, the concept of an NDS-System encapsulates a complex structure of multiple NDS device drivers, combining functions of the different low-level devices and collecting all system-specific logic, separating it from generic device driver code.

TUPV001	The Mirror Systems Benches Kinematics Development for Sirius/LNLS	controls, operation, alignment, MMI	358
	G.N. Kontogiorgos, A.Y. Horita, L. Martins dos Santos, M.A.L. Moraes, L.F. Segalla LNLS, Campinas, Brazil
	Funding: Ministry of Science, Technology and Innovation (MCTI) At Sirius, many of the optical elements such as mirror systems, monochromators, sample holders and detectors are attached to the ground with high stiffnesses to reduce disturbances at the beam during experiments. Granite benches were developed to couple the optical device to the floor and allow automatic movements, via com-manded setpoints on EPICS that runs an embedded kinematics, during base installation, alignment, commis-sioning and operation of the beamline. They are com-posed by stages and each application has its own geome-try, a set number of Degrees-of-Freedom (DoF) and mo-tors, all controlled by Omron Delta Tau Power Brick LV. In particular, the mirror system was the precursor motion control system for other benches. Since the me-chanical design aims on stiffness, the axes of mirror are not controlled directly, the actuators are along the granite bench. A geometric model was created to simplify the mirror operation, which turn the actuators motion trans-parent to the user and allow him to directly control the mirror axes.

TUPV002	Motion Control Improvements for the Kirkpatrick-Baez Mirror System for Sirius/LNLS EMA Beamline	controls, operation, feedback, EPICS	362
	G.N. Kontogiorgos, M.A.L. Moraes, C.S.B.N. Roque LNLS, Campinas, Brazil
	Funding: Ministry of Science, Technology and Innovation (MCTI) The Kirkpatrick-Baez (KB) mirror system is composed of a vertical focusing mirror (VFM) and a horizontal fo-cusing mirror. Both concave mirrors focus the X-ray beam by reflecting it at small grazing angles. The relocation of this system from UVX XDS beamline to Sirius EMA beamline facilitated a full revision of the motion control system, whose controller was migrated to Omron Delta Tau Power Brick LV. The beam focus is controlled by bending the mirrors through camshaft mechanisms cou-pled to low current Faulhaber motors. Although the am-plifier is designed for higher currents, controller settings allowed the use of lower currents. Another improvement made is the ability to drive both bender motors in gantry mode and still control the lag between them. Each bender has a capacitive sensor to monitor the position of the center of the mirror, which is read by the analog input of the controller and made available by EPICS [1]. The VFM is supported by a tripod and a new kinematics was devel-oped to reference the center of the mirror as the point of control. This paper presents the implementation of the new motion control KB system and its results at Sirius EMA beamline.

TUPV009	OpenCMW - A Modular Open Common Middle-Ware Library for Equipment- and Beam-Based Control Systems at FAIR	controls, software, feedback, experiment	392
	R.J. Steinhagen, H. Bräuning, D.S. Day, A. Krimm, T. Milosic, D. Ondreka, A. Schwinn GSI, Darmstadt, Germany
	OpenCMW is an open-source modular event-driven micro- and middle-ware library for equipment- and beam-based monitoring as well as feedback control systems for the FAIR Accelerator Facility. Based on modern C++20 and Java concepts, it provides common communication protocols, interfaces to data visualisation and processing tools that aid engineers and physicists at FAIR in writing functional high-level monitoring and (semi-)automated feedback applications. The focus is put on minimising the required boiler-plate code, programming expertise, common error sources, and significantly lowering the entry-threshold that is required with the framework. OpenCMW takes care of most of the communication, data-serialisation, data-aggregation, settings management, Role-Based-Access-Control (RBAC), and other tedious but necessary control system integrations while still being open to expert-level modifications, extensions or improvements.

TUPV010	Integration of OPC UA at ELBE	controls, LLRF, PLC, SCADA	400
	K. Zenker, M. Kuntzsch, R. Steinbrück HZDR, Dresden, Germany
	The Electron Linac for beams with high Brilliance and low Emittance (ELBE) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is in operation since 2001. It is operated using the SCADA system WinCC by Siemens. The majority of ELBE systems is connected to WinCC via industrial Ethernet and proprietary S7 communication. However, in recent years new subsystems had to be integrated into the existing infrastructure, which do not provide S7 communication interfaces. Instead, OPC UA has been chosen for system integration. We will show how we use OPC UA as a common communication layer between industrial and scientific instruments as well as proprietary and open source control system software. For example, OPC UA support has been implemented for the ChimeraTK framework developed at DESY. ChimeraTK is used at ELBE e.g. for integrating MicroTCA.4 based subsystems like the digital LLRF system. Furthermore, we are developing a machine data interface for ELBE users. In combination with a certification authority, which hands out user certificates for data access, external users can gain read and write access to different ELBE subsystem data provided by a single OPC UA server.

TUPV012	Automated Device Error Handling in Control Applications	controls, EPICS, operation, framework	408
	M. Killenberg, J. Georg, M. Hierholzer, C.K. Kampmeyer, T. Kozak, D. Rothe, N. Shehzad, J.H.K. Timm, G. Varghese, C. Willner DESY, Hamburg, Germany
	When integrating devices into a control system, the device applications usually contain a large fraction of error handling code. Many of these errors are run time errors which occur when communicating with the hardware, and usually have similar handling strategies. Therefore we extended ChimeraTK, a software toolkit for the development of control applications in various control system frameworks, such that the repetition of error handling code in each application can be avoided. ChimeraTK now also features automatic error reporting, recovery from device errors, and proper device initialisation after malfunctioning and at application start.

	Particle accelerators operate in Ultra High Vacuum conditions, which have to be restored after a maintenance activity requiring venting the vacuum chamber. A compact, independent and portable pumping station has been developed at Elettra Sincrotrone Trieste to pump the vacuum chamber and to restore the correct local pressure.. The system automatically achieves a good vacuum level and can detect and manage vacuum leaks . It has been designed and manufactured in-house, including the mechanical, electrical and control parts. By means of a touch screen an operator can start all the manual and automatic operations, and monitor the relevant variables and alarms. The system archives the operating data and displays trends, alarms and logged events; these data are downloadable to a removable USB stick. Controlled devices include two turbomolecular pumps, one primary pump, vacuum gauges and one residual gas analyser. The control system has been implemented with a Beckhoff PLC with RS-485 and Profibus interfaces. This paper focuses in particular on the events management and object-oriented approach adopted to achieve a good modularity and scalability of the system.

	F. Martins, F.M.O. Cuim, G.G. Evans, R.P. Fernandez, A. Gomes, L. Gurriana LIP, Lisboa, Portugal J.A. Soares Augusto FCUL, Lisboa, Portugal
	The preparation of the upgrade of the ATLAS electronics for the High Luminosity LHC is in full swing. The Tile Calorimeter is preparing the upgrade of its readout electronics and power distribution systems. One of such systems is the High Voltage (HV) regulation and distribution system. The new system is based on HVRemote boards mounted in crates located at the counting room. The HV will be delivered to the on-detector electronics using 100 m long cables. The crates will be equipped with a system-on-chip that will be responsible for the control and monitoring of the HV boards. The control of the HVRemote and its dedicated HVSupply boards is done by means of a serial peripheral interface bus. A SCADA component is under development to communicate with and supervise the crates and boards, and to integrate the HV system in the control system of the detector. The control system will be able to send notifications to the operators when the monitored values are out of range, archive the monitored data and if required, perform automated actions.

TUPV035	Continuous Integration for PLC-based Control System Development	PLC, controls, SCADA, hardware	478
	B. Schofield, E. Blanco Viñuela, J.H.P.D.C. Borrego CERN, Geneva, Switzerland
	Continuous Integration and Continuous Deployment (CI/CD) is a software engineering methodology which emphasises frequent, small changes committed to a version control system, which are verified by a suite of automatic tests, and which may be deployed to different environments. While CI/CD is well established in software engineering, it is not yet widely used in the development of industrial controls systems. However, the advantages of using CI/CD for such systems are clear. In this paper we describe a complete CI/CD pipeline able to automatically build Siemens PLC projects from sources, download the program to a PLC, and run a sequence of tests which interact with the PLC via both a Simulation Unit Profibus simulator and an OPC UA interface provided by Simatic NET. To achieve this, a gRPC service wrapping the Simatic API was used to provide an interface to the PLC project from the pipeline. In addition, a Python wrapper was created for the Simulation Unit API, as well as for the OPC UA interface, which allowed the test suite to be implemented in Python. A particle accelerator interlock system based on Siemens S7-300 PLCs has been taken as a use case to demonstrate the concept.

TUPV037	Modular Software Architecture for the New CERN Injector Wire-Scanners	controls, hardware, software, operation	487
	A. Guerrero, D. Belohrad, J. Emery, S. Jackson, F. Roncarolo CERN, Meyrin, Switzerland
	In the scope of the LHC injector upgrade, new wire-scanner devices have been installed in the LHC injector circular accelerators. This paper outlines the software architecture and choices taken in order to provide the scanner experts with comprehensive diagnostics as well as operators with straightforward size measurements. The underlying electronics acquire large amounts of data that need to be accessible for expert and machine develop-ment use and need to be processed before being present-ed for daily operational use, in the shape of a beam pro-file and its derived size. Data delivery and measurement computation are accomplished by means of a modular structure, using functionally distributed real-time process-es that handle the different data views, with minimal interference in the processing, and minimal exchange of data among modules.

TUPV040	A Python Package For Generating Motor Homing Routines	HOM, PLC, controls, status	497
	A.S. Palaha, T.M. Cobb, G. Knap DLS, Oxfordshire, United Kingdom
	Diamond Light Source uses hundreds of Delta Tau Turbo PMAC2 based motion controllers that control motors with precision and repeatability. Homing is critical to these requirements; it safely moves axes to a well-known position using a high-precision device for detection, leaving the overall system in a well-known state and ready for use. A python package called ’pmac_motorhome’ has been developed to generate homing routines for multiple motors across multiple motion controllers, allowing the user to write a script that is terse for standard/typical routines but allows for customisation and flexibility where required. The project uses jinja templates as ‘snippets’ to generate the homing routine code written in Delta Tau PLC notation. The snippets can be re-ordered and grouped together, supporting the design of homing routines for multi-axis systems with mechanical limitations that require an orchestrated approach to safely home the axes. The python script using the package is kept terse using a context manager and can group axes together to the same homing group easily.

	A sustainable infrastructure for provision, interlinkage, maintenance, and options for reuse of research data shall be created in Germany in the coming years. The consortium FAIRmat meets the interests of experimental and theoretical condensed-matter physics. This also includes, for example, chemical physics of solids, synthesis, and high-performance computing. All this is demonstrated by use cases from various areas of functional materials. The necessity of a FAIR data infrastructure in the FAIRmat* research field is very pressing. We need and want to support the actual, daily research work to further science. Besides storing, retrieving, and sharing data, a FAIR data infrastructure will also enable a completely new level of research. In the Area D "Digital Infrastructure" a Configurable Experiment Control System is to be developed here as a reference. EPICS was selected as an initial open source base system. The control system of the newly founded CATlab** in Berlin will be fully implemented according to the FAIRmat specifications.

	H.H. Lv, D.P. Bai, X.M. Liu, H. Zhao SSRF, Shanghai, People’s Republic of China
	Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is a quasi-continuous wave hard X-ray free electron laser facility, which is currently under construction. The image acquisition and storage system has been designed to handle a large quantity of image data generated by the beam and X-ray diagnostics system, the laser system, etc. A prototype system with Camera Link cameras has been developed to acquire and to reliably transport data at a throughput of 1000MB/sec. The image data are transferred through ZeroMQ protocol to the storage where the image data and the relevant metadata are archived and made available for user analysis. For high-speed frames of image data storage, optimized schema is identified by comparing and testing four schemas. The image data are written to HDF5 files and the metadata pertaining to the image are stored in NoSQL database. It could deliver up to 1.2GB/sec storage speed. The performances are also contrasted between a stand-alone server and the Lustre file system. And the Lustre could provide a better performance. Details of the image acquisition, transfer, and storage schemas will be described in the paper.

	T. Zhang, K. Fukushima, T. Maruta, P.N. Ostroumov, A.S. Plastun, Q. Zhao FRIB, East Lansing, Michigan, USA
	Funding: U.S. Department of Energy Office of Science under Cooperative Agreement DESC0000661 The Facility for Rare Isotope Beams (FRIB) at Michigan State University is a unique modern user facility composed of a large-scale superconducting linac capable of accelerating heavy-ion beams from oxygen to uranium. An advanced EPICS-based control system is being used to operate this complex facility. High-level physics applications (HLA) developed before and during the staged commissioning of the linac were one of the critical tools that resulted in achieving the commissioning goals quickly, within several shifts. Many of these HLAs are expandable to other EPCIS controlled accelerators. Recent developed HLAs deal with the management of extensive data to achieve the repetitive high performance of ion beams in the entire linac measured by non-destructive diagnostics instruments, and open the possibilities to explore the extra values out of the data. This paper presents our recent significant development and utilization of these HLAs. * T.

WEBR01	RomLibEmu: Network Interface Stress Tests for the CERN Radiation Monitoring Electronics (CROME)	radiation, network, software, controls	581
	K. Ceesay-Seitz, H. Boukabache, M. Leveneur, D. Perrin CERN, Geneva, Switzerland
	The CERN RadiatiOn Monitoring Electronics are a modular safety system for radiation monitoring that is remotely configurable through a supervisory system via a custom protocol on top of a TCP/IP connection. The configuration parameters influence the safety decisions taken by the system. An independent test library has been developed in Python in order to test the system’s reaction to misconfigurations. It is further used to stress test the application’s network interface and the robustness of the software. The library is capable of creating packets with default values, autocompleting packets according to the protocol and it allows the construction of packets from raw data. Malformed packets can be intentionally crafted and the response of the application under test is checked for protocol conformance. New test cases can be added to the test case dictionary. Each time before a new version of the communication library is released, the Python test library is used for regression testing. The current test suite consists of 251 automated test cases. Many application bugs could be found and solved, which improved the reliability and availability of the system.

WEBR05	Integrated Supervision for Conventional and Machine-Protection Configuration Parameters at ITER	controls, operation, target, GUI	602
	D.A. Karkinsky, J. Jignesh, A. Marqueta, I. Prieto Diaz, W. Van Herck ITER Organization, St. Paul lez Durance, France
	Configuration parameters for ITER’s I&C systems are predominantly high-coupled due to the nature of the process under control. Subsequently, I&C re-configuration requires an integrated supervision approach that addresses coupling through abstraction, automation, scalability, changeability, robustness and re-usability. Moreover, high-coupling might manifest at any tier of the I&C, and certainly spans configuration parameters across both conventional and machine-protection I&C. Stemming from ITER design guidelines, the handling of machine-protection configuration parameters needs to meet the goals of IEC61508-3. These goals are mostly in congruence with the main concerns of integrated supervision identified above. However they also extend requirements that bind the supervision process with traceability and audit capabilities from sources to final self-test (run-time) diagnostics. This presentation describes the provisions for integrated supervision at ITER and elaborates how these provisions can be used to handle machine-protection parameters in compliance with IEC61508-3.

WEPV006	Automated Operation of ITER Using Behavior Tree Semantics	framework, operation, MMI, controls	628
	W. Van Herck, B. Bauvir, G. Ferro ITER Organization, St. Paul lez Durance, France
	The inherent complexity of the ITER machine and the diversity of the ways it will be operated in different phases, like commissioning or engineering operation, poses a great challenge for striking the right balance between operability, integration and automation. To facilitate the creation and execution of operational procedures in a robust and repeatable way, a software framework was developed: the Sequencer. As a supporting framework for tasks that are mostly goal-oriented, the Sequencer’s semantics are based on a behavior tree model that also supports concurrent flows of execution. In view of its intended use in very diverse situations, from small scale tests to full integrated operation, the architecture was designed to be composable and extensible from the start. User interactions with the Sequencer are fully decoupled and can be linked through dependency injection. The Sequencer library is currently feature-complete and comes with a command line interface for the encapsulation of procedures as system daemons or simple interactive use. It is highly maintainable due to its small and low complexity code base and dependencies to third party libraries are properly encapsulated.

	Having multipurpose hardware architectures for controls and monitoring systems has become a need nowadays. When it comes to modular and easy expandable devices, it brings together a system which is easy to maintain and can reach many applications. Concerning Sirius accelerators, which is a 4th generation light source, monitoring environment variables becomes crucial when it comes to accelerator stability and reliability. Several cabinets take part of engineering infrastructure and monitoring and acting over their environment such as internal temperature, pressure and fan status, increases overall system reliability. This paper presents a non-expensive hardware topology to deal with multiple sensors and actuators mainly designed to monitor cabinets and prevent beam quality loss due to equipment faults.

	Funding: Work supported by the Brazilian Ministry of Science, Technology and Innovation The beamlines and front ends at Sirius, the Brazilian 4th generation synchrotron light source, require monitoring and protection systems for personal and equipment safety in general, due to the high beam power dissipated along the beamline, vacuum safety, secure radiation levels, use of robots, special gases, cryogenic systems, and other highly sensitive and costly equipment throughout the facility. Two distinct programable logic controllers (PLC) were then deployed to create the Equipment Protection System (EPS) and the Personal Protection System (PPS). This work presents an overview of the EPS/PPS - requirements, architecture, design and deployment details, and commissioning results for the first set of beamlines.

WEPV040	Design of Machine Protection System for SXFEL-UF	FEL, controls, operation, vacuum	750
	C.L. Yu, J.G. Ding, H. Zhao SSRF, Shanghai, People’s Republic of China
	Shanghai Soft X-ray Free-Electron Laser (SXFEL) facility is divided into two phases: the SXFEL test facility (SXFEL-TF) and the SXFEL user facility (SXFEL-UF). SXFEL-TF has met all the design specifications and has been available in beam operating state. SXFEL-UF is currently under commissioning and is planned to generate 3 nm FEL radiation using a 1.5 GeV electron LINAC. To protect the critical equipment rapidly and effectively from unexpected damage, a reliable safety interlocking system needs to be designed. Machine Protection System (MPS) is designed by Programmable Logic Controller (PLC) and Experimental Physics and Industrial Control System (EPICS) which is based on a master-slave architecture. In order to meet different commissioning and operation requirements, the management and switching functions of eight operation modes are introduced in the MPS system. There are two FEL line in user facility named SXFEL beamline project (BSP) and undulator (UD) , and the corresponding design of MPS is completed. This paper focuses on the progress and challenges associated with the SXFEL-UF MPS.

WEPV041	Implementation of a VHDL Application for Interfacing Anybus CompactCom	network, neutron, FPGA, PLC	755
	S. Gabourin, A. Nordt, S. Pavinato ESS, Lund, Sweden
	The European Spallation Source (ESS ERIC), based in Lund (Sweden), will be in a few years the most powerful neutron source in Europe with an average beam power of 5 MW. It will accelerate proton beam pulses to a Tungsten wheel to generate neutrons by the spallation effect. For such beam, the Machine Protection System (MPS) at ESS must be fast and reliable, and for this reason a Fast Beam Interlock System (FBIS) based on FPGAs is required. Some protection functions monitoring slow values (like temperature, mechanical movements, magnetic fields) need however less strict reaction times and are managed by PLCs. The communications protocol established between PLCs and FBIS is PROFINET fieldbus based. The Anybus CompactCom allows an host to have connectivity to industrial networks as PROFINET. In this context, FBIS represents the host and the application code to interface the AnyBus CompactCom has been fully developed in VHDL. This paper describes an open source implementation to interface a CompactCom M40 with an FPGA.

	ITER will produce large volumes of data that need to be visualized and analyzed. This paper describes the development of a graphical data visualization and exploration tool, MINT (Make Informative and Nice Trends), for plant engineers, operators and physicists. It describes the early development phase from requirements capture to first release covering the mistakes, lessons learnt and future steps. The requirements were collected by interviewing the various stakeholders. The initial neglect of the architecture and user-friendliness turned out to be key points when developing such a tool for a project with a long lifetime like ITER. Modular architecture and clear definition of generic interfaces (abstraction layer) is crucial for such a long lifetime project and makes it ready for future adaptations to new plotting, processing and GUI libraries. The MINT application is based upon the development of an independent plotting library, which acts as a wrapper to the underlying graphical library. This allows scientists and engineers to develop their own specific tools, which are immune to changes of graphical library. The development based on Python uses Qt5 as the visual backend.

	MACE Scheduler software generates automated schedule for the observations of preloaded high energy gamma-ray sources. The paper presents the design of MACE Scheduler software covering; source rise/set time calculation algorithms; auto and manual schedule generation; various data visualizations provided for schedule and source visibility reports. The schedule generation for a specific period is automated using a filter workflow. The sources are selected for scheduling by processing the sources through a series of customizable user defined filters; source visibility filter, priority filter, priority resolution filter. The workflow provides flexibility to apply any user tailored filter criteria that can be loaded dynamically using XML schema. Loosely coupled design allowed decoupling the astronomical timing calculation algorithms from schedule preparation workflow. Scheduler provides metro UI based interface for source filtering workflow generating auto-schedule, updating the generated schedules. Tree-map visualization helped to represent hierarchical multi-dimensional schedule information for the selected date range. WPF flat UI control templates focused more on content than chrome

	The ALMA Observatory was inaugurated in 2013, after the 8 years of successful operation, obsolescence has started to emerge in different areas. One of the most critical areas is the control bus of the hardware devices located the antenna, which is based on a customized version of CAN bus. Initial studies were performed to explore alternatives, and one of the candidates could be a solution based on EtherCAT. In this paper, the existing architecture will be presented and new architecture will be proposed, which would not only be compatible with the existing hardware devices but also allow prepared the ground for new subsystems that come with ALMA 2030 initiatives. This document reports the progress achieved in a proof of concept project that explores the possibility to embed the existing ALMA monitor & control data structure into EtherCAT frames and use EtherCAT as the main communication protocol to control hardware devices in all the subsystems that comprise the ALMA telescope.

THBR01	Renovation of the Trigger Distribution in CERN’s Open Analogue Signal Information System Using White Rabbit	network, controls, hardware, timing	839
	D. Lampridis, T. Gingold, A. Poscia, M.H. Serans, M.R. Shukla, T.P. da Silva CERN, Geneva, Switzerland D. Michalik Aalborg University, Aalborg, Denmark
	The Open Analogue Signal Information System (OASIS) acts as a distributed oscilloscope system that acquires signals from devices across the CERN accelerator complex and displays them in a convenient, graphical way. Today, the OASIS installation counts over 500 multiplexed digitisers, capable of digitising more than 5000 analogue signals and offers a selection of more than 250 triggers for the acquisitions. These triggers are mostly generated at a single central place and are then distributed by means of a dedicated coaxial cable per digitiser, using a "star" topology. An upgrade is currently under way to renovate this trigger distribution system and migrate it to a White Rabbit (WR) based solution. In this new system, triggers are distributed in the form of Ethernet messages over a WR network, allowing for better scalability, higher time-stamping precision, trigger latency compensation and improved robustness. This paper discusses the new OASIS trigger distribution architecture, including hardware, drivers, front-end, server and application-tier software. It then provides results from preliminary tests in laboratory installations.

THPV006	Design of Real-Time Alarm System for CAFe	controls, real-time, status, monitoring	867
	N. Xie, Y.H. Guo, B.J. Wang, R. Wang IMP/CAS, Lanzhou, People’s Republic of China
	In accelerator control, the alarm system is a very im-portant real-time monitoring and control system. In order to find specific failures of accelerator-related equipment in time, improve the high availability of the equipment, and ensure the long-term operation of the accelerator. An accelerator alarm system based on Kafka was designed and built on the CAFe. The system uses Phoebus for ar-chitecture deployment. Kafka is used as the streaming platform of the alarm system, which effectively improves the throughput of the system and realizes real-time alarms. In order to realize the function of remote monitor-ing of data in the central control room, CS-Studio is used to draw the opi interface to deploy to the enterprise WeChat platform to realize remote data monitoring. This system greatly improves the response speed of fault han-dling and saves a lot of valuable time for accelerator fault handling.

THPV007	Fast Creation of Control and Monitor Graphical User Interface for PEPC of Laser Fusion Facility Based on ICSFF	controls, software, framework, monitoring	871
	L. Li, J. Luo, Z. Ni CAEP, Sichuan, People’s Republic of China
	Plasma electrode Pockels cell (PEPC) is the key unit of the multi-pass amplify system in laser fusion facility, whether the PEPC is effective determined the success rate of the facility experiment directly. The operator needs to conduct remote control and monitor during the facility is running, also can automatically judge whether the pulse discharge waveform is regular online. We have designed a software framework (ICSFF) that loads all GUI widget elements related to control and monitor into board through plug-ins, and then by setting the respective properties, data source and built-in script of each widget achieve patterns like point control, flow control and other complex combined control, can also achieve data acquisition and varied display effects. It allows the operator drag and drop widget freely and configure the widget properties through the interface in a non-programming mode to quickly build the GUI they need. It not only apply to PEPC in facility, but also to other system in the same facility. ICSFF supports Tango control system right now, and more control systems will be supported in the future.

	D. Bisiach, M. Cargnelutti, P. Leban, P. Paglovec, L. Rahne, M. Škabar, A. Vigali I-Tech, Solkan, Slovenia
	During the past 5 years, Instrumentation Technologies expanded and added to the embedded OS running on Libera instruments (beam position instrumentation, LLRF) a lot of data access interfaces to allow faster access to the signals retrieved by the instrument. Some of the access interfaces are strictly related to the user environment Machine control system (Epics/Tango), and others related to the user software preferences (Matlab/Python). In the last years, the requirement for easier data streaming was raised to allow easier data access using PC and mobile phones through a web browser. This paper aims to present the development of the web backend server and the realization of a web frontend capable to process the data retrieved by the instrument. A use-case will be presented, the realization of the Libera Current Meter Web GUI as a first development example of a Web GUI interface for a Libera instrument and the starting point for the Web GUI pipeline integration on other instruments. The HTTP access interface will become in the next years a standard in data access for Libera instrumentation for quick testing/diagnostics and will allow the final user to customize it autonomously.

THPV013	WRAP - A Web-Based Rapid Application Development Framework for CERN’s Controls Infrastructure	controls, GUI, framework, software	894
	E. Galatas, A. Asko, E. Matli, C. Roderick CERN, Geneva, Switzerland
	To ensure stable operation of CERN’s accelerator complex, many Devices need to be controlled. To meet this need, over 500 custom Graphical User Interfaces (GUI) have been developed using Java Swing, Java FX, NetBeans, Eclipse SWT, etc. These represent a high maintenance cost, particularly considering the global evolution of the GUI technology landscape. The new Web-based Rapid Application Platform (WRAP) provides a centralized, zero-code, drag-n-drop means of GUI creation. It aims to replace a significant percentage of existing GUIs and ease new developments. Integration with the Controls Configuration Service (CCS) provides rich infrastructure metadata to support application configuration, whilst following the associated equipment lifecycle (e.g. renames, upgrades, dismantling). Leveraging the CERN Accelerator Logging Service (NXCALS) and the Unified Controls Acquisition and Processing (UCAP) platform, allows WRAP users to respectively, create GUIs showing historical data, and interface with complex data-stream processing. The plugin architecture will allow teams to further extend the tool as needed. This paper describes the WRAP architecture, design, status, and outlook.

THPV014	Adopting PyQt for Beam Instrumentation GUI Development at CERN	GUI, controls, MMI, operation	899
	S. Zanzottera, S. Jackson, S. Jensen CERN, Geneva, Switzerland
	As Java GUI toolkits become deprecated, the Beam Instrumentation (BI)group at CERN has investigated alternatives and selected PyQt as one of the suitable technologies for future GUIs, in accordance with the paper presented at ICALEPCS19. This paper presents tools created, or adapted, to seamlessly integrate future PyQt GUI development alongside current Java oriented workflows and the controls environment. This includes (a) creating a project template and a GUI management tool to ease and standardize our development process, (b) rewriting our previously Java-centric Expert GUI Launcher to be language-agnostic and (c) porting a selection of operational GUIs from Java to PyQt, to test the feasibility of the development process and identify bottlenecks. To conclude, the challenges we anticipate for the BI GUI developer community in adopting this new technology are also discussed.

THPV015	New Timing Sequencer Application in Python with Qt - Development Workflow and Lessons Learnt	timing, controls, GUI, MMI	904
	Zs. Kovari, G. Kruk CERN, Meyrin, Switzerland
	PyQt is a Python binding for the popular Qt framework for the development of desktop applications. By using PyQt one can leverage Qt’s aspects to implement modern, intuitive, and cross-platform applications while benefiting from Python’s flexibility. Recently, we successfully used PyQt 5 to renovate the Graphical User Interface (GUI) used to control the CERN accelerator timing system. The GUI application interfaces with a Java-based service behind the scenes. In this paper we introduce the generic architecture used for this project, our development workflow as well as the challenges and lessons we learned from using Python with Qt. We present our approach to delivering an operational application with a particular focus on testing, quality assurance, and continuous integration.

THPV022	MRF Timing System Design at SARAF	timing, controls, EPICS, operation	912
	A. Gaget CEA-IRFU, Gif-sur-Yvette, France
	CEA Saclay Irfu is in charge of an important part of the control system of the SARAF LINAC accelerator based at Soreq (Israel). This includes, among other, the control of the timing system (synchronization and timestamping). CEA has already installed and uses successfully the timing distribution with MRF on test benches for ESS or IPHI, so it has been decided to use the same technologies. The reference frequency will be distributed along the accelerator by a master oscillator Wenzel and the UTC time will be based on a Meridian II GPS, these 2 devices will be connected to the Event Master (EVM) card which is the main element of the timing system architecture. Through an optical fiber network, the MRF timing system allows to distribute downstream and upstream events with a µs propagation time. Currently, we are working on development in order to also use it for the machine protection system of the accelerator. In this paper, hardware, timing architecture, software developments and tests will be presented.

THPV033	Reusable Real-Time Software Components for the SPS Low Level RF Control System	hardware, software, controls, Linux	939
	M. Sumiński, K. Adrianek, B. Bielawski, A.C. Butterworth, J. Egli, G. Hagmann, P. Kuzmanović, S. Novel González, A. Rey, A. Spierer CERN, Geneva, Switzerland
	In 2021 the Super Proton Synchrotron has been recommissioned after a complete renovation of its low level RF system (LLRF). The new system has largely moved to digital signal processing implemented as a set of functional blocks (IP cores) in Field Programmable Gate Arrays (FPGAs) with associated software to control them. Some of these IP cores provide generic functionalities such as timing, function generation, data resampling and signal acquisition, and are reused in several components, with a potential application in other accelerators. To take full advantage of the modular approach, IP core flexibility must be complemented by the software stack. In this paper we present steps we have taken to reach this goal from the software point of view, and describe the custom tools and procedures used to implement the various software layers.

THPV038	Plug-in-Based Ptychography & CDI Reconstruction User Interface Development	operation, framework, synchrotron, detector	950
	S.W. Kim, K.H. Ku, W.W. Lee PAL, Pohang, Republic of Korea
	Synchrotron beamlines have a wide range of fields, and accordingly, various open source and commercial softwares are being used for data analysis. Inevitable, the user interface differs between programs and there is little shared part, so the user had to spend a lot of effort to perform a new experimental analysis and learn how to use the program newly. In order to overcome these shortcomings, the same user interface was maintained using the Xi-cam framework, and different analysis algorithms for each field were introduced in a plugin method. In this presentation, user interfaces designed for ptychography and cdi reconstruction will be introduced.

	The remote control and monitoring of accelerators and experimental setup has become an essential enabler when remote work has become the norm for the last 2 years. Unlike the desktop user interfaces which have been developed for the use of physical workstations, Web application are naturally accessible remotely via the ubiquitous web browsers. On the other hand, Web technology development need a specific knowledge which has yet to be disseminate in the control system engineering. And desktop frameworks still have the benefit of rapid and easy development even for the non-specialist. Taranta Suite is a collection of web applications jointly developed by MAX IV Laboratory and the SKA Organization, for the Tango Control System. Totally in line with the ’no-code’ trend, truly little knowledge of web technologies is needed. An operator can create a graphical user interface on-the-fly and then, can share instantly this application. Authentication and authorization ensure to give the right level access to the users. This paper will describe the system, the React and GQL implementation and the first usage at the different facilities.

	G. Strangolino, L. Zambon Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	Funding: * inspiration by Alessio Igor Bogani, Elettra, Trieste, Italy On the wake of former web interfaces developed at ELETTRA as well as in other institutes, the service and development framework for the web and platform independent applications named PUMA has been substantially enhanced and rewritten, with the additional objectives of high availability, scalability, load balancing, responsiveness and customization. Thorough analysis of Websocket limits led to an SSE based server technology relying on channels (Nchan over NGINX) to deliver the events to the clients. The development of the latter is supported by JQuery, Bootstrap, D3js, SVG and QT and helps build interfaces ranging from mobile to dashboard. Ultimate developments led to successful load balancing and failover actions, owing to the joint cooperation of a dedicated service supervisor and the NGINX upstream module.

	Funding: Most from Ministry of Science and Technology of the people’s Republic of China The deployment of the control system called CODAC (Control, Data Access and Communications) is necessary for the operation of large-scale experimental facilities. CFET (Control system framework for experimental devic-es toolkit) is a flexible SCADA (supervisory control and data acquisition) software tool, which is used for the construction of a CODAC. CFET is fully based on open web technologies, it is easy to integrate all kinds of systems and devices into CFET. This paper has undergone a major iteration of CFET. HMI has been redesigned and implemented. The control engineer can use a web based WYSIWYG HMI editor to compose the HMI. In CFET, InfluxDB has been integrated. It is used to store the engineering data, and also visualize the data on the website. Docker based microservices architecture has been designed, putting CFET and dependent packages into a lightweight container. At present, CFET has been used in the CO-DAC system of J-TEXT tokamak and HUST Field-Reversed Configuration facility.

	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Advanced Scientific Computing Research under Award Number DE-SC00215553. The design, execution, and analysis of light source experiments requires the use of increasingly complex simulation, controls and data management tools. Existing workflows require significant specialization to account for beamline-specific operations and pre-processing steps in order to collect and prepare data for more sophisticated analysis. Recent efforts to address these needs at the National Synchrotron Light Source II (NSLS-II) have resulted in the creation of the Bluesky data collection framework, an open-source library providing for experimental control and scientific data collection via high level abstraction of experimental procedures, instrument readouts, and data analysis. We present a prototype data management interface that couples with Bluesky to support guided simulation, measurement, and rapid processing operations. Initial demonstrations illustrate application to coherent X-ray scattering beamlines at the NSLS-II. We then discuss extensions of this interface to permit analysis operations across distributed computing resources, including the use of the Sirepo scientific framework, as well as Jupyter notebooks running on remote computing clusters.

FRBR03	Status of Bluesky Deployment at BESSY II	controls, EPICS, experiment, detector	1064
	W. Smith, S. Kazarski, R. Müller, P. Schnizer, S. Vadilonga, L. Vera Ramiréz HZB, Berlin, Germany
	The modernization plan for the experimental DAQ at the BESSY II is underpinned by the capabilities provided by the Bluesky software ecosystem. To interface with the hardware Bluesky relies on the Ophyd library, that provides a consistent high-level interface across a wide-range of devices. Many elements of the accelerator, some beamlines and endstations are adopting the Bluesky software. To meet FAIR data obligations, the capture of metadata with Bluesky and the export into a permanent and easily accessible storage called ICAT are investigated. Finally, initial studies to investigate the integration of ML methods, like reinforcement learning were performed. This paper reports on the work that has been done so far at BESSY II to adopt Bluesky, problems that have been overcome and lessons learned.

ASTRON, Dwingeloo, The Netherlands

After 10 years of operation, the LOw Frequency ARray (LOFAR) telescope is undergoing a significant hardware upgrade towards LOFAR2.0. The hardware upgrade will enable the phased array telescope to observe at 10-90 MHz and at 120-240 MHz frequencies at the same time. With the upgrade comes also the chance to review LOFAR’s Control System and to make it ready for the next 10 years of operation at the forefront of low-frequency astronomy. In this work we will give a brief overview over the LOFAR telescope with its more than 50 geographically distributed receiver locations (LOFAR Stations), and the software that is necessary to monitor and control every single one of them. We will then describe the Station Control architecture, with its software design and how it is implemented in Python 3 with Tango Controls, OPC-UA clients and deployed as Docker containers. Lastly we will report on the successful use of open stack software like ELK and, Grafana.

The Extremely Large Telescope (ELT) is a 39m optical telescope under construction in the Chilean Atacama desert. The design is based on a five-mirror scheme, incorporating Adaptive Optics (AO). The primary mirror consists of 798 segments with 1.4m diameter. The main control challenges can be identified in the number of sensors (~25000) and actuators (~15000) to be coordinated, the computing performance and small latency required for phasing of the primary mirror and the AO. We focus on the design and implementation of the supervisory systems and control strategies. This includes a real time computing (RTC) toolkit to support the implementation of the AO for telescope and instruments. We will also report on the progress done in the implementation of the control software infrastructure necessary for development, testing and integration. We identify a few lessons learned in the past years of development and major challenges for the coming phases of the project.

The Cherenkov Telescope Array (CTA) is the next-generation ground-based gamma-ray observatory. Its design comprises close to 100 imaging atmospheric Cherenkov telescopes deployed at a southern (Paranal, Chile) and a northern (La Palma, Canary Islands, Spain) site. The inclusion of various array elements, like Large-Sized, Medium-Sized and Small-Sized Telescopes, instruments for atmosphere monitoring, etc, into the Array Control and Data Acquisition System (ACADA) poses a particular challenge which is met by an appropriate software architecture and a well-defined interface for array elements. This conference contribution describes exemplarily how the interface is implemented for the Medium-Sized Telescopes (MSTs, 12m diameter). The implementation uses the ALMA Common Software (ACS) as a framework for software applications facilitating the readout and control of telescope subsystems like the drive system or the pointing camera; the communication with subsystems takes advantage of the OPC UA protocol. It is also discussed what technologies (e.g. data bases) are used for the acquisition and storage of telescope-specific monitoring data.

At DESY, an upgrade of the PETRA III synchrotron light source towards a fourth-generation, low emittance machine PETRA IV is currently being actively pursued. The basic concept of the control system of PETRAIV is to exploit synergies between all accelerator facilities operated by DESY. The key figures of PETRAIV’s new accelerator control system include the DOOCS control system framework, high-end MTCA.4 technology compliant hardware interfaces for triggered, high-performance applications and hardware interfaces for conventional slow-control applications compliant with industrial process control standards such as OPC UA, and enhanced data acquisition and data storage capabilities. In addition, the suitability of standards for graphical user interfaces based on novel Web application technologies will be investigated. Finally, there is a general focus on improving quality management and quality assurance measures, including proper configuration management, requirements management, bug tracking, software development, and software lifetime management. The paper will report on the current state of development.

CERN, Geneva, Switzerland

In this paper we report the experience from a large-scale upgrade campaign of SCADA control systems performed during the second LHC Long Shutdown at CERN. Such periodical upgrades are dictated by the ever evolving SCADA WinCC OA system and the CERN frameworks evolution used in those control systems. These upgrades concern: accelerator control systems, e.g. quench protection system, powering interlocks, magnet alignment; control systems devoted to accelerator facilities such as cryogenics, vacuum, gas… and other global technical infrastructure systems as well as the CERN electrical distribution system. Since there are more than 200 SCADA projects covering the CERN accelerator complex and technical infrastructure, any disruption requires careful coordination, planning and execution with process owners. Having gained experience from previous campaigns and reaching a new level of automation we were able to make visible improvements by shortening the required time and reducing the personnel required. Activities, lessons learned and further improvements are presented as well as a comprehensive statistical insight of the whole campaign.

OPC Unified Architecture (OPC UA) is an open platform independent communication architecture for industrial automation developed by the OPC Foundation. Its key characteristics include a rich service-oriented architecture, enhanced security functionality and an integral information model, allowing to map complex data into an OPC UA namespace. With its increasing popularity in the industrial world, OPC UA is an excellent strategic choice for integrating a wealth of different COTS devices and controllers into an existing control system infrastructure. The security functions extend its application to larger networks and across firewalls, while the support of user-defined data structures and fully symbolic addressing ensure flexibility, separation of concerns and robustness in the user interfaces. In an international collaboration, a generic OPC UA support for the EPICS control system toolkit has been developed. It is used in operation at several facilities, integrating a variety of commercial controllers and systems. We describe design and implementation approach, discuss use cases and software quality aspects, report performance and present a roadmap of the next development steps.

The institute of modern physics (IMP) has two sets of linear accelerator facilities, they are CAFe (China ADS front-end demo linac) and LEAF (Low Energy Accelerator Facility). The Main equipment of LEAF facility consists of ion source, LEBT (Low Energy Beam Transport), RFQ (Radio Frequency Quadrupole) and some experiment terminals. Compare with LEAF, CAFe equipment has more and adds MEBT (Middle Energy Beam Transport) and four sets of superconducting cavity strings at the back end of RFQ. In the process of commissioning and running linac equipment, The EPICS Archiver application and Alarm system are used. According to the refined control requirements of the facility sites, we have completed the software upgrade and deployment of the archiver and alarm systems. The upgraded software systems have made the operation of linac machines more effective in term of monitoring, fault-diagnostic and system recovery, and becomes more user-friendly as well.

StreamDevice, as a general-purpose string interface device’s Epics driver, has been widely used in the control of devices with network and serial ports in CAFe equipment. For example, the remote control of magnet power supply, vacuum gauges, and various vacuum valves or pumps, as well as the information reading and control of Gauss meter equipment used in magnetic field measurement. In the process of on-site software development, we found that various errors are caused during the deployment of StreamDevice about the dependence on software environment and library functions, which because of different operating system environments and EPICS tool software versions. This makes StreamDevice deployment very time-consuming and labor-intensive. To ensure that StreamDevice works in a unified environment and can be deployed and migrated efficiently, the Docker container technology is used to encapsulate its software and its application environment. Images will be uploaded to an Aliyun private library to facilitate software developers to download and use.

Building C++ software for low-level computers requires carefully tested frameworks and libraries. The major difficulties in building C++ software are to ensure that the artifacts are compatible with the target system’s (OS, Application Binary Interface), and to ensure that transitive dependent libraries are compatible when linked together. Thus developers/maintainers must be provided with efficient tooling for friction-less workflows: standardisation of the project description and build, automatic CI, flexible development environment. The open-source community with services like Github and Gitlab have set high expectations with regards to developer user experience. This paper describes how we leveraged Conan and CMake to standardise the build of C++ projects, avoid the "dependency hell" and provide an easy way to distribute C++ packages. A CI system orchestrated by Jenkins and based on automatic job definition and in-source, versioned, configuration has been implemented. The developer experience is further enhanced by wrapping the common flows (compile, test, release) into a command line tool, which also helps transitioning from the legacy build system (legacy makefiles, SVN).

Python provides broad design freedom to programmers and a low barrier of entry for new software developers. These aspects have proven that unless standardized, a Python codebase will tend to diverge from a common style and architecture, becoming unmaintainable across the scope of a large controls system. Mitigating these effects requires a set of tools, standards, and procedures developed to assert boundaries on certain aspects of Python development – namely project organization, version management, and deployment procedures. Common tools like Git, GitLab, and virtual environments form a basis for development, with in-house utilities presenting their capabilities in a clear, developer-focused way. This paper describes the necessary constraints needed for development and deployment of large-scale Python applications, the function of the tools which comprise the development environment, and how these tools are leveraged to create simple and effective procedures to guide development.

In the field of Experimental Physics and Industrial Control Systems (EPICS)*, the traditional tool to implement high level procedures is the Sequencer*. While this is a mature, fast, and well-proven software, it comes with some drawbacks. For example, it’s based on a custom C-like programming language which may be unfamiliar to new users and it often results in complex, hard to read code. This paper presents pysmlib, a free and open source Python library developed as a simpler alternative to the EPICS Sequencer. The library exposes a simple interface to develop event-driven Finite State Machines (FSM), where the inputs are connected to Channel Access Process Variables (PV) thanks to the PyEpics** integration. Other features include parallel FSM with multi-threading support and input sharing, timers, and an integrated watchdog logic. The library offers a lower barrier to enter and greater extensibility thanks to the large ecosystem of scientific and engineering python libraries, making it a perfect fit for modern control system requirements. Pysmlib has been deployed in multiple projects at INFN Legnaro National Laboratories (LNL), proving its robustness and flexibility.

Software integration of diverse data acquisition and timing hardware devices in diagnostics applications is very challenging. While the implementation should manage multiple hardware devices from different manufacturers providing different applications program interfaces (APIs), scientists would rather focus on the high level configuration, using their specific environment such as EPICS, Tango, the ITER Real-Time Framework or the MARTe2 middleware. The Nominal Device Support (NDSv3) C++ framework, conceived by Cosylab and under development at ITER for use in its diagnostic applications, uses a layered approach, abstracting specific hardware device APIs as well as the interface to control systems and real-time applications. ITER CODAC and its partners have developed NDS device drivers using both PXIe and MTCA platforms for multifunction DAQ devices, timing cards and FPGA-based solutions. In addition, the concept of an NDS-System encapsulates a complex structure of multiple NDS device drivers, combining functions of the different low-level devices and collecting all system-specific logic, separating it from generic device driver code.

At Sirius, many of the optical elements such as mirror systems, monochromators, sample holders and detectors are attached to the ground with high stiffnesses to reduce disturbances at the beam during experiments. Granite benches were developed to couple the optical device to the floor and allow automatic movements, via com-manded setpoints on EPICS that runs an embedded kinematics, during base installation, alignment, commis-sioning and operation of the beamline. They are com-posed by stages and each application has its own geome-try, a set number of Degrees-of-Freedom (DoF) and mo-tors, all controlled by Omron Delta Tau Power Brick LV. In particular, the mirror system was the precursor motion control system for other benches. Since the me-chanical design aims on stiffness, the axes of mirror are not controlled directly, the actuators are along the granite bench. A geometric model was created to simplify the mirror operation, which turn the actuators motion trans-parent to the user and allow him to directly control the mirror axes.

The Kirkpatrick-Baez (KB) mirror system is composed of a vertical focusing mirror (VFM) and a horizontal fo-cusing mirror. Both concave mirrors focus the X-ray beam by reflecting it at small grazing angles. The relocation of this system from UVX XDS beamline to Sirius EMA beamline facilitated a full revision of the motion control system, whose controller was migrated to Omron Delta Tau Power Brick LV. The beam focus is controlled by bending the mirrors through camshaft mechanisms cou-pled to low current Faulhaber motors. Although the am-plifier is designed for higher currents, controller settings allowed the use of lower currents. Another improvement made is the ability to drive both bender motors in gantry mode and still control the lag between them. Each bender has a capacitive sensor to monitor the position of the center of the mirror, which is read by the analog input of the controller and made available by EPICS [1]. The VFM is supported by a tripod and a new kinematics was devel-oped to reference the center of the mirror as the point of control. This paper presents the implementation of the new motion control KB system and its results at Sirius EMA beamline.

OpenCMW is an open-source modular event-driven micro- and middle-ware library for equipment- and beam-based monitoring as well as feedback control systems for the FAIR Accelerator Facility. Based on modern C++20 and Java concepts, it provides common communication protocols, interfaces to data visualisation and processing tools that aid engineers and physicists at FAIR in writing functional high-level monitoring and (semi-)automated feedback applications. The focus is put on minimising the required boiler-plate code, programming expertise, common error sources, and significantly lowering the entry-threshold that is required with the framework. OpenCMW takes care of most of the communication, data-serialisation, data-aggregation, settings management, Role-Based-Access-Control (RBAC), and other tedious but necessary control system integrations while still being open to expert-level modifications, extensions or improvements.

HZDR, Dresden, Germany

The Electron Linac for beams with high Brilliance and low Emittance (ELBE) at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is in operation since 2001. It is operated using the SCADA system WinCC by Siemens. The majority of ELBE systems is connected to WinCC via industrial Ethernet and proprietary S7 communication. However, in recent years new subsystems had to be integrated into the existing infrastructure, which do not provide S7 communication interfaces. Instead, OPC UA has been chosen for system integration. We will show how we use OPC UA as a common communication layer between industrial and scientific instruments as well as proprietary and open source control system software. For example, OPC UA support has been implemented for the ChimeraTK framework developed at DESY. ChimeraTK is used at ELBE e.g. for integrating MicroTCA.4 based subsystems like the digital LLRF system. Furthermore, we are developing a machine data interface for ELBE users. In combination with a certification authority, which hands out user certificates for data access, external users can gain read and write access to different ELBE subsystem data provided by a single OPC UA server.

When integrating devices into a control system, the device applications usually contain a large fraction of error handling code. Many of these errors are run time errors which occur when communicating with the hardware, and usually have similar handling strategies. Therefore we extended ChimeraTK, a software toolkit for the development of control applications in various control system frameworks, such that the repetition of error handling code in each application can be avoided. ChimeraTK now also features automatic error reporting, recovery from device errors, and proper device initialisation after malfunctioning and at application start.

Particle accelerators operate in Ultra High Vacuum conditions, which have to be restored after a maintenance activity requiring venting the vacuum chamber. A compact, independent and portable pumping station has been developed at Elettra Sincrotrone Trieste to pump the vacuum chamber and to restore the correct local pressure.. The system automatically achieves a good vacuum level and can detect and manage vacuum leaks . It has been designed and manufactured in-house, including the mechanical, electrical and control parts. By means of a touch screen an operator can start all the manual and automatic operations, and monitor the relevant variables and alarms. The system archives the operating data and displays trends, alarms and logged events; these data are downloadable to a removable USB stick. Controlled devices include two turbomolecular pumps, one primary pump, vacuum gauges and one residual gas analyser. The control system has been implemented with a Beckhoff PLC with RS-485 and Profibus interfaces. This paper focuses in particular on the events management and object-oriented approach adopted to achieve a good modularity and scalability of the system.

The preparation of the upgrade of the ATLAS electronics for the High Luminosity LHC is in full swing. The Tile Calorimeter is preparing the upgrade of its readout electronics and power distribution systems. One of such systems is the High Voltage (HV) regulation and distribution system. The new system is based on HVRemote boards mounted in crates located at the counting room. The HV will be delivered to the on-detector electronics using 100 m long cables. The crates will be equipped with a system-on-chip that will be responsible for the control and monitoring of the HV boards. The control of the HVRemote and its dedicated HVSupply boards is done by means of a serial peripheral interface bus. A SCADA component is under development to communicate with and supervise the crates and boards, and to integrate the HV system in the control system of the detector. The control system will be able to send notifications to the operators when the monitored values are out of range, archive the monitored data and if required, perform automated actions.

Continuous Integration for PLC-based Control System Development

CERN, Geneva, Switzerland

Continuous Integration and Continuous Deployment (CI/CD) is a software engineering methodology which emphasises frequent, small changes committed to a version control system, which are verified by a suite of automatic tests, and which may be deployed to different environments. While CI/CD is well established in software engineering, it is not yet widely used in the development of industrial controls systems. However, the advantages of using CI/CD for such systems are clear. In this paper we describe a complete CI/CD pipeline able to automatically build Siemens PLC projects from sources, download the program to a PLC, and run a sequence of tests which interact with the PLC via both a Simulation Unit Profibus simulator and an OPC UA interface provided by Simatic NET. To achieve this, a gRPC service wrapping the Simatic API was used to provide an interface to the PLC project from the pipeline. In addition, a Python wrapper was created for the Simulation Unit API, as well as for the OPC UA interface, which allowed the test suite to be implemented in Python. A particle accelerator interlock system based on Siemens S7-300 PLCs has been taken as a use case to demonstrate the concept.

In the scope of the LHC injector upgrade, new wire-scanner devices have been installed in the LHC injector circular accelerators. This paper outlines the software architecture and choices taken in order to provide the scanner experts with comprehensive diagnostics as well as operators with straightforward size measurements. The underlying electronics acquire large amounts of data that need to be accessible for expert and machine develop-ment use and need to be processed before being present-ed for daily operational use, in the shape of a beam pro-file and its derived size. Data delivery and measurement computation are accomplished by means of a modular structure, using functionally distributed real-time process-es that handle the different data views, with minimal interference in the processing, and minimal exchange of data among modules.

A Python Package For Generating Motor Homing Routines

HOM, PLC, controls, status

497

A.S. Palaha, T.M. Cobb, G. Knap
DLS, Oxfordshire, United Kingdom

Diamond Light Source uses hundreds of Delta Tau Turbo PMAC2 based motion controllers that control motors with precision and repeatability. Homing is critical to these requirements; it safely moves axes to a well-known position using a high-precision device for detection, leaving the overall system in a well-known state and ready for use. A python package called ’pmac_motorhome’ has been developed to generate homing routines for multiple motors across multiple motion controllers, allowing the user to write a script that is terse for standard/typical routines but allows for customisation and flexibility where required. The project uses jinja templates as ‘snippets’ to generate the homing routine code written in Delta Tau PLC notation. The snippets can be re-ordered and grouped together, supporting the design of homing routines for multi-axis systems with mechanical limitations that require an orchestrated approach to safely home the axes. The python script using the package is kept terse using a context manager and can group axes together to the same homing group easily.

Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is a quasi-continuous wave hard X-ray free electron laser facility, which is currently under construction. The image acquisition and storage system has been designed to handle a large quantity of image data generated by the beam and X-ray diagnostics system, the laser system, etc. A prototype system with Camera Link cameras has been developed to acquire and to reliably transport data at a throughput of 1000MB/sec. The image data are transferred through ZeroMQ protocol to the storage where the image data and the relevant metadata are archived and made available for user analysis. For high-speed frames of image data storage, optimized schema is identified by comparing and testing four schemas. The image data are written to HDF5 files and the metadata pertaining to the image are stored in NoSQL database. It could deliver up to 1.2GB/sec storage speed. The performances are also contrasted between a stand-alone server and the Lustre file system. And the Lustre could provide a better performance. Details of the image acquisition, transfer, and storage schemas will be described in the paper.

The Facility for Rare Isotope Beams (FRIB) at Michigan State University is a unique modern user facility composed of a large-scale superconducting linac capable of accelerating heavy-ion beams from oxygen to uranium. An advanced EPICS-based control system is being used to operate this complex facility. High-level physics applications (HLA) developed before and during the staged commissioning of the linac were one of the critical tools that resulted in achieving the commissioning goals quickly, within several shifts. Many of these HLAs are expandable to other EPCIS controlled accelerators. Recent developed HLAs deal with the management of extensive data to achieve the repetitive high performance of ion beams in the entire linac measured by non-destructive diagnostics instruments, and open the possibilities to explore the extra values out of the data. This paper presents our recent significant development and utilization of these HLAs.

CERN, Geneva, Switzerland

The CERN RadiatiOn Monitoring Electronics are a modular safety system for radiation monitoring that is remotely configurable through a supervisory system via a custom protocol on top of a TCP/IP connection. The configuration parameters influence the safety decisions taken by the system. An independent test library has been developed in Python in order to test the system’s reaction to misconfigurations. It is further used to stress test the application’s network interface and the robustness of the software. The library is capable of creating packets with default values, autocompleting packets according to the protocol and it allows the construction of packets from raw data. Malformed packets can be intentionally crafted and the response of the application under test is checked for protocol conformance. New test cases can be added to the test case dictionary. Each time before a new version of the communication library is released, the Python test library is used for regression testing. The current test suite consists of 251 automated test cases. Many application bugs could be found and solved, which improved the reliability and availability of the system.

Integrated Supervision for Conventional and Machine-Protection Configuration Parameters at ITER

602

ITER Organization, St. Paul lez Durance, France

Configuration parameters for ITER’s I&C systems are predominantly high-coupled due to the nature of the process under control. Subsequently, I&C re-configuration requires an integrated supervision approach that addresses coupling through abstraction, automation, scalability, changeability, robustness and re-usability. Moreover, high-coupling might manifest at any tier of the I&C, and certainly spans configuration parameters across both conventional and machine-protection I&C. Stemming from ITER design guidelines, the handling of machine-protection configuration parameters needs to meet the goals of IEC61508-3. These goals are mostly in congruence with the main concerns of integrated supervision identified above. However they also extend requirements that bind the supervision process with traceability and audit capabilities from sources to final self-test (run-time) diagnostics. This presentation describes the provisions for integrated supervision at ITER and elaborates how these provisions can be used to handle machine-protection parameters in compliance with IEC61508-3.

Automated Operation of ITER Using Behavior Tree Semantics

628

W. Van Herck, B. Bauvir, G. Ferro
ITER Organization, St. Paul lez Durance, France

The inherent complexity of the ITER machine and the diversity of the ways it will be operated in different phases, like commissioning or engineering operation, poses a great challenge for striking the right balance between operability, integration and automation. To facilitate the creation and execution of operational procedures in a robust and repeatable way, a software framework was developed: the Sequencer. As a supporting framework for tasks that are mostly goal-oriented, the Sequencer’s semantics are based on a behavior tree model that also supports concurrent flows of execution. In view of its intended use in very diverse situations, from small scale tests to full integrated operation, the architecture was designed to be composable and extensible from the start. User interactions with the Sequencer are fully decoupled and can be linked through dependency injection. The Sequencer library is currently feature-complete and comes with a command line interface for the encapsulation of procedures as system daemons or simple interactive use. It is highly maintainable due to its small and low complexity code base and dependencies to third party libraries are properly encapsulated.

Having multipurpose hardware architectures for controls and monitoring systems has become a need nowadays. When it comes to modular and easy expandable devices, it brings together a system which is easy to maintain and can reach many applications. Concerning Sirius accelerators, which is a 4th generation light source, monitoring environment variables becomes crucial when it comes to accelerator stability and reliability. Several cabinets take part of engineering infrastructure and monitoring and acting over their environment such as internal temperature, pressure and fan status, increases overall system reliability. This paper presents a non-expensive hardware topology to deal with multiple sensors and actuators mainly designed to monitor cabinets and prevent beam quality loss due to equipment faults.

The beamlines and front ends at Sirius, the Brazilian 4th generation synchrotron light source, require monitoring and protection systems for personal and equipment safety in general, due to the high beam power dissipated along the beamline, vacuum safety, secure radiation levels, use of robots, special gases, cryogenic systems, and other highly sensitive and costly equipment throughout the facility. Two distinct programable logic controllers (PLC) were then deployed to create the Equipment Protection System (EPS) and the Personal Protection System (PPS). This work presents an overview of the EPS/PPS - requirements, architecture, design and deployment details, and commissioning results for the first set of beamlines.

SSRF, Shanghai, People’s Republic of China

Shanghai Soft X-ray Free-Electron Laser (SXFEL) facility is divided into two phases: the SXFEL test facility (SXFEL-TF) and the SXFEL user facility (SXFEL-UF). SXFEL-TF has met all the design specifications and has been available in beam operating state. SXFEL-UF is currently under commissioning and is planned to generate 3 nm FEL radiation using a 1.5 GeV electron LINAC. To protect the critical equipment rapidly and effectively from unexpected damage, a reliable safety interlocking system needs to be designed. Machine Protection System (MPS) is designed by Programmable Logic Controller (PLC) and Experimental Physics and Industrial Control System (EPICS) which is based on a master-slave architecture. In order to meet different commissioning and operation requirements, the management and switching functions of eight operation modes are introduced in the MPS system. There are two FEL line in user facility named SXFEL beamline project (BSP) and undulator (UD) , and the corresponding design of MPS is completed. This paper focuses on the progress and challenges associated with the SXFEL-UF MPS.

ESS, Lund, Sweden

The European Spallation Source (ESS ERIC), based in Lund (Sweden), will be in a few years the most powerful neutron source in Europe with an average beam power of 5 MW. It will accelerate proton beam pulses to a Tungsten wheel to generate neutrons by the spallation effect. For such beam, the Machine Protection System (MPS) at ESS must be fast and reliable, and for this reason a Fast Beam Interlock System (FBIS) based on FPGAs is required. Some protection functions monitoring slow values (like temperature, mechanical movements, magnetic fields) need however less strict reaction times and are managed by PLCs. The communications protocol established between PLCs and FBIS is PROFINET fieldbus based. The Anybus CompactCom allows an host to have connectivity to industrial networks as PROFINET. In this context, FBIS represents the host and the application code to interface the AnyBus CompactCom has been fully developed in VHDL. This paper describes an open source implementation to interface a CompactCom M40 with an FPGA.

ITER will produce large volumes of data that need to be visualized and analyzed. This paper describes the development of a graphical data visualization and exploration tool, MINT (Make Informative and Nice Trends), for plant engineers, operators and physicists. It describes the early development phase from requirements capture to first release covering the mistakes, lessons learnt and future steps. The requirements were collected by interviewing the various stakeholders. The initial neglect of the architecture and user-friendliness turned out to be key points when developing such a tool for a project with a long lifetime like ITER. Modular architecture and clear definition of generic interfaces (abstraction layer) is crucial for such a long lifetime project and makes it ready for future adaptations to new plotting, processing and GUI libraries. The MINT application is based upon the development of an independent plotting library, which acts as a wrapper to the underlying graphical library. This allows scientists and engineers to develop their own specific tools, which are immune to changes of graphical library. The development based on Python uses Qt5 as the visual backend.

MACE Scheduler software generates automated schedule for the observations of preloaded high energy gamma-ray sources. The paper presents the design of MACE Scheduler software covering; source rise/set time calculation algorithms; auto and manual schedule generation; various data visualizations provided for schedule and source visibility reports. The schedule generation for a specific period is automated using a filter workflow. The sources are selected for scheduling by processing the sources through a series of customizable user defined filters; source visibility filter, priority filter, priority resolution filter. The workflow provides flexibility to apply any user tailored filter criteria that can be loaded dynamically using XML schema. Loosely coupled design allowed decoupling the astronomical timing calculation algorithms from schedule preparation workflow. Scheduler provides metro UI based interface for source filtering workflow generating auto-schedule, updating the generated schedules. Tree-map visualization helped to represent hierarchical multi-dimensional schedule information for the selected date range. WPF flat UI control templates focused more on content than chrome

The ALMA Observatory was inaugurated in 2013, after the 8 years of successful operation, obsolescence has started to emerge in different areas. One of the most critical areas is the control bus of the hardware devices located the antenna, which is based on a customized version of CAN bus. Initial studies were performed to explore alternatives, and one of the candidates could be a solution based on EtherCAT. In this paper, the existing architecture will be presented and new architecture will be proposed, which would not only be compatible with the existing hardware devices but also allow prepared the ground for new subsystems that come with ALMA 2030 initiatives. This document reports the progress achieved in a proof of concept project that explores the possibility to embed the existing ALMA monitor & control data structure into EtherCAT frames and use EtherCAT as the main communication protocol to control hardware devices in all the subsystems that comprise the ALMA telescope.

The Open Analogue Signal Information System (OASIS) acts as a distributed oscilloscope system that acquires signals from devices across the CERN accelerator complex and displays them in a convenient, graphical way. Today, the OASIS installation counts over 500 multiplexed digitisers, capable of digitising more than 5000 analogue signals and offers a selection of more than 250 triggers for the acquisitions. These triggers are mostly generated at a single central place and are then distributed by means of a dedicated coaxial cable per digitiser, using a "star" topology. An upgrade is currently under way to renovate this trigger distribution system and migrate it to a White Rabbit (WR) based solution. In this new system, triggers are distributed in the form of Ethernet messages over a WR network, allowing for better scalability, higher time-stamping precision, trigger latency compensation and improved robustness. This paper discusses the new OASIS trigger distribution architecture, including hardware, drivers, front-end, server and application-tier software. It then provides results from preliminary tests in laboratory installations.

Virtual Reality (VR) technology and its derivatives are mature enough to be used in environments like a nuclear research laboratory, to provide useful tools and procedures to optimize the tasks of developers and operators. Preliminary tests were performed [*] to understand the feasibility of this technology applied to a nuclear physics laboratory with promising feedback. Due to the fact this technology is rapidly diffusing in several different professional heterogeneous environments, such as medicine, architecture, the military and industry, we tried to evaluate the impact coming from a new kind of Human-Machine Interface based on VR.

In accelerator control, the alarm system is a very im-portant real-time monitoring and control system. In order to find specific failures of accelerator-related equipment in time, improve the high availability of the equipment, and ensure the long-term operation of the accelerator. An accelerator alarm system based on Kafka was designed and built on the CAFe. The system uses Phoebus for ar-chitecture deployment. Kafka is used as the streaming platform of the alarm system, which effectively improves the throughput of the system and realizes real-time alarms. In order to realize the function of remote monitor-ing of data in the central control room, CS-Studio is used to draw the opi interface to deploy to the enterprise WeChat platform to realize remote data monitoring. This system greatly improves the response speed of fault han-dling and saves a lot of valuable time for accelerator fault handling.

CAEP, Sichuan, People’s Republic of China

Plasma electrode Pockels cell (PEPC) is the key unit of the multi-pass amplify system in laser fusion facility, whether the PEPC is effective determined the success rate of the facility experiment directly. The operator needs to conduct remote control and monitor during the facility is running, also can automatically judge whether the pulse discharge waveform is regular online. We have designed a software framework (ICSFF) that loads all GUI widget elements related to control and monitor into board through plug-ins, and then by setting the respective properties, data source and built-in script of each widget achieve patterns like point control, flow control and other complex combined control, can also achieve data acquisition and varied display effects. It allows the operator drag and drop widget freely and configure the widget properties through the interface in a non-programming mode to quickly build the GUI they need. It not only apply to PEPC in facility, but also to other system in the same facility. ICSFF supports Tango control system right now, and more control systems will be supported in the future.

During the past 5 years, Instrumentation Technologies expanded and added to the embedded OS running on Libera instruments (beam position instrumentation, LLRF) a lot of data access interfaces to allow faster access to the signals retrieved by the instrument. Some of the access interfaces are strictly related to the user environment Machine control system (Epics/Tango), and others related to the user software preferences (Matlab/Python). In the last years, the requirement for easier data streaming was raised to allow easier data access using PC and mobile phones through a web browser. This paper aims to present the development of the web backend server and the realization of a web frontend capable to process the data retrieved by the instrument. A use-case will be presented, the realization of the Libera Current Meter Web GUI as a first development example of a Web GUI interface for a Libera instrument and the starting point for the Web GUI pipeline integration on other instruments. The HTTP access interface will become in the next years a standard in data access for Libera instrumentation for quick testing/diagnostics and will allow the final user to customize it autonomously.

894

E. Galatas, A. Asko, E. Matli, C. Roderick
CERN, Geneva, Switzerland

To ensure stable operation of CERN’s accelerator complex, many Devices need to be controlled. To meet this need, over 500 custom Graphical User Interfaces (GUI) have been developed using Java Swing, Java FX, NetBeans, Eclipse SWT, etc. These represent a high maintenance cost, particularly considering the global evolution of the GUI technology landscape. The new Web-based Rapid Application Platform (WRAP) provides a centralized, zero-code, drag-n-drop means of GUI creation. It aims to replace a significant percentage of existing GUIs and ease new developments. Integration with the Controls Configuration Service (CCS) provides rich infrastructure metadata to support application configuration, whilst following the associated equipment lifecycle (e.g. renames, upgrades, dismantling). Leveraging the CERN Accelerator Logging Service (NXCALS) and the Unified Controls Acquisition and Processing (UCAP) platform, allows WRAP users to respectively, create GUIs showing historical data, and interface with complex data-stream processing. The plugin architecture will allow teams to further extend the tool as needed. This paper describes the WRAP architecture, design, status, and outlook.

CERN, Geneva, Switzerland

As Java GUI toolkits become deprecated, the Beam Instrumentation (BI)group at CERN has investigated alternatives and selected PyQt as one of the suitable technologies for future GUIs, in accordance with the paper presented at ICALEPCS19. This paper presents tools created, or adapted, to seamlessly integrate future PyQt GUI development alongside current Java oriented workflows and the controls environment. This includes (a) creating a project template and a GUI management tool to ease and standardize our development process, (b) rewriting our previously Java-centric Expert GUI Launcher to be language-agnostic and (c) porting a selection of operational GUIs from Java to PyQt, to test the feasibility of the development process and identify bottlenecks. To conclude, the challenges we anticipate for the BI GUI developer community in adopting this new technology are also discussed.

CERN, Meyrin, Switzerland

PyQt is a Python binding for the popular Qt framework for the development of desktop applications. By using PyQt one can leverage Qt’s aspects to implement modern, intuitive, and cross-platform applications while benefiting from Python’s flexibility. Recently, we successfully used PyQt 5 to renovate the Graphical User Interface (GUI) used to control the CERN accelerator timing system. The GUI application interfaces with a Java-based service behind the scenes. In this paper we introduce the generic architecture used for this project, our development workflow as well as the challenges and lessons we learned from using Python with Qt. We present our approach to delivering an operational application with a particular focus on testing, quality assurance, and continuous integration.

CEA-IRFU, Gif-sur-Yvette, France

CEA Saclay Irfu is in charge of an important part of the control system of the SARAF LINAC accelerator based at Soreq (Israel). This includes, among other, the control of the timing system (synchronization and timestamping). CEA has already installed and uses successfully the timing distribution with MRF on test benches for ESS or IPHI, so it has been decided to use the same technologies. The reference frequency will be distributed along the accelerator by a master oscillator Wenzel and the UTC time will be based on a Meridian II GPS, these 2 devices will be connected to the Event Master (EVM) card which is the main element of the timing system architecture. Through an optical fiber network, the MRF timing system allows to distribute downstream and upstream events with a µs propagation time. Currently, we are working on development in order to also use it for the machine protection system of the accelerator. In this paper, hardware, timing architecture, software developments and tests will be presented.

In 2021 the Super Proton Synchrotron has been recommissioned after a complete renovation of its low level RF system (LLRF). The new system has largely moved to digital signal processing implemented as a set of functional blocks (IP cores) in Field Programmable Gate Arrays (FPGAs) with associated software to control them. Some of these IP cores provide generic functionalities such as timing, function generation, data resampling and signal acquisition, and are reused in several components, with a potential application in other accelerators. To take full advantage of the modular approach, IP core flexibility must be complemented by the software stack. In this paper we present steps we have taken to reach this goal from the software point of view, and describe the custom tools and procedures used to implement the various software layers.

Synchrotron beamlines have a wide range of fields, and accordingly, various open source and commercial softwares are being used for data analysis. Inevitable, the user interface differs between programs and there is little shared part, so the user had to spend a lot of effort to perform a new experimental analysis and learn how to use the program newly. In order to overcome these shortcomings, the same user interface was maintained using the Xi-cam framework, and different analysis algorithms for each field were introduced in a plugin method. In this presentation, user interfaces designed for ptychography and cdi reconstruction will be introduced.

The remote control and monitoring of accelerators and experimental setup has become an essential enabler when remote work has become the norm for the last 2 years. Unlike the desktop user interfaces which have been developed for the use of physical workstations, Web application are naturally accessible remotely via the ubiquitous web browsers. On the other hand, Web technology development need a specific knowledge which has yet to be disseminate in the control system engineering. And desktop frameworks still have the benefit of rapid and easy development even for the non-specialist. Taranta Suite is a collection of web applications jointly developed by MAX IV Laboratory and the SKA Organization, for the Tango Control System. Totally in line with the ’no-code’ trend, truly little knowledge of web technologies is needed. An operator can create a graphical user interface on-the-fly and then, can share instantly this application. Authentication and authorization ensure to give the right level access to the users. This paper will describe the system, the React and GQL implementation and the first usage at the different facilities.

On the wake of former web interfaces developed at ELETTRA as well as in other institutes, the service and development framework for the web and platform independent applications named PUMA has been substantially enhanced and rewritten, with the additional objectives of high availability, scalability, load balancing, responsiveness and customization. Thorough analysis of Websocket limits led to an SSE based server technology relying on channels (Nchan over NGINX) to deliver the events to the clients. The development of the latter is supported by JQuery, Bootstrap, D3js, SVG and QT and helps build interfaces ranging from mobile to dashboard. Ultimate developments led to successful load balancing and failover actions, owing to the joint cooperation of a dedicated service supervisor and the NGINX upstream module.

The deployment of the control system called CODAC (Control, Data Access and Communications) is necessary for the operation of large-scale experimental facilities. CFET (Control system framework for experimental devic-es toolkit) is a flexible SCADA (supervisory control and data acquisition) software tool, which is used for the construction of a CODAC. CFET is fully based on open web technologies, it is easy to integrate all kinds of systems and devices into CFET. This paper has undergone a major iteration of CFET. HMI has been redesigned and implemented. The control engineer can use a web based WYSIWYG HMI editor to compose the HMI. In CFET, InfluxDB has been integrated. It is used to store the engineering data, and also visualize the data on the website. Docker based microservices architecture has been designed, putting CFET and dependent packages into a lightweight container. At present, CFET has been used in the CO-DAC system of J-TEXT tokamak and HUST Field-Reversed Configuration facility.

The design, execution, and analysis of light source experiments requires the use of increasingly complex simulation, controls and data management tools. Existing workflows require significant specialization to account for beamline-specific operations and pre-processing steps in order to collect and prepare data for more sophisticated analysis. Recent efforts to address these needs at the National Synchrotron Light Source II (NSLS-II) have resulted in the creation of the Bluesky data collection framework*, an open-source library providing for experimental control and scientific data collection via high level abstraction of experimental procedures, instrument readouts, and data analysis. We present a prototype data management interface that couples with Bluesky to support guided simulation, measurement, and rapid processing operations. Initial demonstrations illustrate application to coherent X-ray scattering beamlines at the NSLS-II. We then discuss extensions of this interface to permit analysis operations across distributed computing resources, including the use of the Sirepo scientific framework, as well as Jupyter notebooks running on remote computing clusters**.

The modernization plan for the experimental DAQ at the BESSY II is underpinned by the capabilities provided by the Bluesky software ecosystem. To interface with the hardware Bluesky relies on the Ophyd library, that provides a consistent high-level interface across a wide-range of devices. Many elements of the accelerator, some beamlines and endstations are adopting the Bluesky software. To meet FAIR data obligations, the capture of metadata with Bluesky and the export into a permanent and easily accessible storage called ICAT are investigated. Finally, initial studies to investigate the integration of ML methods, like reinforcement learning were performed. This paper reports on the work that has been done so far at BESSY II to adopt Bluesky, problems that have been overcome and lessons learned.
