  Since 2012, an effort started to replace the ageing electrical supervision system (managing more than 200,000 tags) currently in operation with a WinCC OA-based supervision system in order to unify the monitoring systems used by CERN operators and to leverage the internal knowledge and development of the products (JCOP, UNICOS, etc.). Along with the classical functionalities of a typical SCADA system (alarms, event, trending, archiving, access control, etc.), the supervision of the CERN electrical network requires a set of domain specific applications gathered under the name of EMS (Energy Management System). Such applications include network coloring, state estimation, power flow calculations, contingency analysis, optimal power flow, etc. Additionally, as electrical power is a critical service for CERN, a high availability of its infrastructure, including its supervision system, is required. The supervision system is therefore redundant along with a disaster recovery system which is itself redundant. In this paper, we will present the overall architecture of the future supervision system with an emphasis on the parts specific to the supervision of electrical network.

  Recently, more and more PLCs are adopted for various frontend controls of　accelerators. It is common to connect the PLCs with higher level control layers by the network. As a result, control logic becomes dispersed over separate layers, one of which is implemented by ladder programs on PLCs, and the other is implemented by higher level languages on frontend computers. EPICS-based SuperKEKB accelerator control system, however, take a different approach by using FA-M3 PLCs with a special CPU module (F3RP61), which runs Linux and functions as an IOC. This consolidation of PLC and IOC enables higher level applications to directly reach every PLC placed at frontends by Channel Access. In addition, most of control logic can be implemented by the IOC core program and/or EPICS sequencer to make the system more homogeneous resulting in easier development and maintenance of applications. This type of PLC-based IOCs are to be used to monitor and control many subsystems of SuperKEKB, such as personnel protection system, vacuum system, RF system, magnet power supplies, and so on. This paper describes the applications of the PLC-based IOCs to the SuperKEKB accelerator control system.

  The French Atomic Energy Commission(CEA)has just built an integration platform outside the LMJ facility in order to assemble the various components of the Integrated Control Command System(ICCS). The talk gives an overview of this integration platform and the qualification strategy based on the use of equipment simulators, and focuses on several tools that have been developed to integrate each sub-system and qualify the overall behavior of the ICCS. Each delivery kit of a sub-system component(Virtual Machine, WIM, PLC,.) is scanned by antivirus software and stored in the delivery database. A specific tool allows the deployment of the delivery kits on the hardware platform (a copy of the LMJ hardware platform). Then, the TMW(Testing Management Workstation) performs automatic tests by coordinating the equipment simulators behavior and the operator’s behavior. The tests configurations, test scenarios and test results are stored in another database. Test results are analyzed, every dysfunction is stored in an event data base which is used to perform reliability calculation of each component. The qualified software is delivered on the LMJ to perform the commissioning of each bundle.

The Advanced Radiographic Capability (ARC) currently under development for the National Ignition Facility (NIF) will provide short (1-50 picoseconds) ultra high power (>1 Petawatt) laser pulses used for a variety of diagnostic purposes on NIF ranging from a high energy x-ray pulse source for backlighter imaging to an experimental platform for fast-ignition. A single NIF Quad (4 beams) is being upgraded to support experimentally driven, autonomous operations using either ARC or existing NIF pulses. Using its own seed oscillator, ARC generates short, wide bandwidth pulses that propagate down the existing NIF beamlines for amplification before being redirected through large aperture gratings that perform chirped pulse compression, generating a series of high-intensity pulses within the target chamber. This significant effort to integrate the ARC adds 40% additional control points to the existing NIF Quad and will be deployed in several phases over the coming year. This talk discusses some new unique ARC software controls used for short pulse operation on NIF and integration techniques being used to expedite deployment of this new diagnostic.

  Renovation of the control system of the CERN LHC injectors was initiated in 2007 in the scope of the Injector Controls Architecture (InCA) project. One of its main objectives was to homogenize the controls software across CERN accelerators and reuse as much as possible the existing modern sub-systems, such as the settings management used for the LHC. The project team created a platform that would permit coexistence and intercommunication between old and new components via a dedicated gateway, allowing a progressive replacement of the former. Dealing with a heterogeneous environment, with many diverse and interconnected modules, implemented using different technologies and programming languages, the team had to introduce all the modifications in the smoothest possible way, without causing machine downtime. After a brief description of the system architecture, the paper discusses the technical and non-technical sides of the renovation process such as validation and deployment methodology, operational applications and diagnostic tools characteristics and finally users’ involvement and human aspects, outlining good decisions, pitfalls and lessons learned over the last five years.

MOCOBAB06 Integrated Monitoring and Control Specification Environment 47

  Monitoring and control solutions for large one-off systems are typically built in silos using multiple tools and technologies. Functionality such as data processing logic, alarm handling, UIs, device drivers are implemented by manually writing configuration code in isolation and their cross dependencies maintained manually. The correctness of the created specification is checked using manually written test cases. Non-functional requirements – such as reliability, performance, availability, reusability and so on – are addressed in ad hoc manner. This hinders evolution of systems with long lifetimes. For ITER, we developed an integrated specifications environment and a set of tools to generate configurations for target execution platforms, along with required glue to realize the entire M&C solution. The SKA is an opportunity to enhance this framework further to include checking for functional and engineering properties of the solution based on domain best practices. The framework includes three levels: domain-specific, problem-specific and target technology-specific. We discuss how this approach can address three major facets of complexity: scale, diversity and evolution.

The National Ignition Facility (NIF) at LLNL is a 2.0 Mega joule laser with ~100,000 control points managed by ~2,000 networked computers. The installation of the controls system began in 2002 with prototype controls for one quad. By 2004 the controls system build-out began and over the next 6 years the remainder was installed and activated. The NIF has now transitioned to a user facility with a 30 year operational lifespan. As with many large, long duration projects the controls system diversity has created maintenance issues and components have reached end-of-life. This requires the controls team to develop and execute a controls hardware refresh cycle to replace aging components before reliability issues interfere with facility operations. This refresh also affects the controls system software since modernization of controls hardware and operating system require corresponding software changes and possibly coding language changes. This talk addresses the NIF controls system maintenance and refresh strategy, including plans to evolve towards a more homogenous controls posture, and also discusses the extended schedule required to transition to the new platform base.

The control system architecture of modern experimental physics facilities needs to meet the requirements of the ever increasing complexity of the controlled devices. Whenever feasible, moving from a distributed architecture based on powerful but complex and expensive computers to an even more pervasive approach based on simple and cheap embedded systems, allows shifting the knowledge close to the devices. The BeagleBone computer, being capable of running a full featured operating system such as GNU/Linux, integrates effectively into the existing control systems and allows executing complex control functions with the required flexibility. The paper discusses the choice of the BeagleBone as embedded platform and reports some examples of control applications recently developed for the ELETTRA and FERMI@Elettra light sources.

  SOLEIL * is a third generation Synchrotron radiation source located near Paris in France. REVOLUTION (REconsider Various contrOLler for yoUr moTION) is the motion controller upgrade project at SOLEIL. It was initiated by the first « Motion control workshop in radiation facilities » in May 2011 that allowed development of an international motion control community in large research facilities. The next meeting will take place during pre-ICALEPS workshop: Motion Control Applications in Large Facilities **.  As motion control is an essential key element in assuring optimal results, but also at a competitive price, the REVOLUTION team selected alternatives by following a theoretical and practical methodology:  advanced market analysis, tests, measures and impact evaluation. Products from two major motion control manufacturers are on the short list. They must provide the best performance for a small selection of demanding applications, and the lowest global cost to maintain operational conditions for the majority of applications at SOLEIL. The search for the best technical, economical and organizational compromise to face our challenges is detailed in this paper.

  ITER requires extensive diagnostics to meet the requirements for machine operation, protection, plasma control and physics studies. The realization of these systems is a major challenge not only because of the harsh environment and the nuclear requirements but also with respect to plant system Instrumentation and Control (I&C) of all the 45 diagnostics systems since the procurement arrangements of the ITER diagnostics with the domestic agencies require a large number of high performance fast controllers whose choice is based on guidelines and catalogues published by the ITER Organization (IO). The goal is to simplify acceptance testing and commissioning for both domestic agencies and the IO. For this purpose several diagnostic use case examples for plant system I&C documentation and implementation are provided by IO to the domestic agencies. Their implementations cover major parts of the diagnostic plant system I&C such as multi-channel high performance data and image acquisition, data processing as well as real-time and data archiving aspects. In this paper, the current status and achievements in implementation and documentation for the use case examples are presented.

  In the IFMIF EVEDA project, normal conducting Radio Frequency Quadrupole (RFQ) is used to bunch and accelerate a 130 mA steady beam to 5 MeV. RFQ cavity is divided into three structures, named super-modules. Each super-module is divided into 6 modules for a total of 18 modules for the overall structure. The final three modules have to be tested at high power to test and validate the most critical RF components of RFQ cavity and, on the other hand, to test performances of the main ancillaries that will be used for IFMIF EVEDA project (vacuum manifold system, tuning system and control system). The choice of the last three modules is due to the fact that they will operate in the most demanding conditions in terms of power density (100 kW/m) and surface electric field (1.8*Ekp). The Experimental Physics and Industrial Control System (EPICS) environment [1] provides the framework for monitoring any equipment connected to it. This paper report the usage of this framework to the RFQ power tests at Legnaro National Laboratories [2][3].

  A general control system of the Materials and Life science experimental Facility (MLF-GCS) consists of programmable logic controllers (PLCs), operator interfaces (OPI) of iFix, data servers, and so on. It is controlling various devices such as a mercury target and a personnel protection system. The present system has been working well but there are problems in view of maintenance and update because of poor flexibility of OS and version compatibility. To overcome the weakness of the system, we decided to replace it to an advanced system based on EPICS and CSS as a framework and OPI software, which has advantages of high scalability and usability. Then we built a prototype system, connected it to the current MLF-GCS, and examined its performance. As the result, the communication between the EPICS/CSS system and the PLCs was successfully implemented by mediating a Takebishi OPC server, true data of 7000 were stored with suitable speed and capacity in a new data storage server based on a PostgreSQL, and OPI functions of the CSS were verified. We concluded through these examinations that the EPICS/CSS system had function and performance specified to the advanced MLF-GCS.

  The National Synchrotron Light Source II is under construction at Brookhaven National Laboratory, Upton, USA. NSLS-II consists of linac, transport lines, booster synchrotron and the storage ring. The main features of booster are 1 or 2 Hz cycle and beam energy ramp from 200 MeV up to 3 GeV in 300 msec. EPICS is chosen as a base for the NSLS-II Control System. The booster control system covers all parts of the facility such as power supplies, timing system, diagnostics, vacuum system and many others. Each part includes a set of various electronic devices and a lot of parameters which shall be fully defined for the control system software. This paper considers an approach proposed for defining some equipment of the NSLS-II Booster. It provides a description of different entities of the facility in a uniform way. This information is used to generate configuration files for EPICS IOCs. The main goal of this approach is to put information in one place and elimination of data duplication. Also this approach simplifies configuration and modification of the description and makes it more clear and easily usable by engineers and operators.

  Periodically the alignment of LHC collimators needs to be verified. Access for personnel is limited due to the level of radiation close to the collimators. The required measurements precision must be comparable to the other equipment in the LHC tunnel, meaning 0.15 mm in a sliding window of 200 m. Hence conventional measurements would take 4 days for a team of 3 people. This presentation covers the design, development and commissioning of a remotely controlled system able performs the same measurements in 1 h with one operator. The system includes the integration of a variety of industrial devices ranging from position sensors, inclination sensors to video cameras, all linked to a PXI system running LabVIEW. The control of the motors is done through a PLC based system. The overall performance and user experience are reported.

  The monitoring and control of the CERN electrical network involves a large variety of devices and software: it ranges from acquisition devices to data concentrators, supervision systems as well as power network simulation tools. The main issue faced nowadays for the engineering of such large and heterogeneous system including more than 20,000 devices and 200,000 tags is that all devices and software have their own data engineering tool while many of the configuration data have to be shared between two or more devices: the same data needs to be entered manually to the different tools leading to duplication of effort and many inconsistencies. This paper presents a tool called ENSDM aiming at centralizing all the data needed to engineer the monitoring and control infrastructure into a single database from which the configuration of the various devices is extracted automatically. Such approach allows the user to enter the information only once and guarantee the consistency of the data across the entire system. The paper will focus more specifically on the configuration of the remote terminal unit) devices, the global supervision system (SCADA) and the power network simulation tools.

  The CERN Unified Industrial Control System framework (UNICOS) with its Continuous Control Package (UNICOS CPC) is the CERN standard solution for the design and implementation of continuous industrial process control applications. The in-house designed communication mechanism, based on the Time Stamp Push Protocol (TSPP) provides event driven high performance data communication between the control and supervision layers of a UNICOS CPC application. In its recent implementation of full redundant capabilities for both control and supervision layers, the TSPP protocol has reached maturity. This paper presents the design of the redundancy, the architecture, the current implementation as well as a comprehensive evaluation of its performance for SIEMENS PLCs in different test scenarios.

  This paper describes the movement control system for detector positioning based on the Roman Pot design used by the ATLAS-ALFA and TOTEM experiments at the LHC. A key system requirement is that LHC machine protection rules are obeyed: the position is surveyed every 20ms with an accuracy of 15?m. If the detectors move too close to the beam (outside limits set by LHC Operators) the LHC interlock system is triggered to dump the beam. LHC Operators in the CERN Control Centre (CCC) drive the system via an HMI provided by a custom built Java application which uses Common Middleware (CMW) to interact with lower level components. Low-level motorization control is executed using National Instruments PXI devices. The DIM protocol provides the software interface to the PXI layer. A FESA gateway server provides a communication bridge between CMW and DIM. A cut down laboratory version of the system was built to provide a platform for verifying the integrity of the full chain, with respect to user and machine protection requirements, and validating new functionality before deploying to the LHC. The paper contains a detailed system description, test bench results and foreseen system improvements.

  Large vacuum systems at CERN (Large Hadron Collider, the Low Energy Ion Rings…) require bake-out to achieve ultra-high vacuum specifications. The bake-out cycle is used to decrease the outgassing rate of the vacuum vessel and to activate the Non-Evaporable Getter (NEG) thin film. Bake-out control is a Proportional-Integral-Derivative (PID) regulation with complex recipes, interlocks and troubleshooting management and remote control. It is based on mobile Programmable Logic Controller (PLC) cabinets, fieldbus network and Supervisory Control and Data Acquisition (SCADA) application. CERN vacuum installations include more than 7 km of baked vessels; using mobile cabinets reduces considerably the cost of the control system. The cabinets are installed close to the vacuum vessels during the time of the bake-out cycle. Mobile cabinets can be used in all the CERN vacuum facilities. Remote control is provided by fieldbus network and SCADA application.

  After 3 years of operation, the LHC entered its first Long Shutdown period (LS1), in February 2013. Major consolidation and maintenance works will be performed across the whole CERN’s accelerator chain, in order to prepare the LHC to restart at higher energy, in 2015. The rest of the accelerator complex shall resume in mid-2014. We report on the recent and on-going vacuum-controls projects. Some of them are associated with the consolidations of the vacuum systems of LHC and of its injectors; others concern the complete renovation of the controls of some machines; and there are also some completely new installations. Due to the wide age-span of the existing vacuum installations, there is a mix of design philosophies and of control-equipment generations. The renovation and the novel projects offer an opportunity to improve the Quality Assurance of vacuum controls by: identifying, documenting, naming and labelling all pieces of equipment; minimising the number of equipment versions with similar functionality; homogenising the control architectures, while converging to a single software framework.

  The MedAustron accelerator is a synchrotron for light-ion therapy, developed under the guidance of CERN within the MedAustron-CERN collaboration. Procurement of 7 different power converter families and development of the control system were carried out concurrently. Control is optimized for unattended routine clinical operation. Therefore, finding a uniform control solution was paramount to fulfill the ambitious project plan. Another challenge was the need to operate with about 5'000 cycles initially, achieving pipelined operation with pulse-to-pulse re-configuration times smaller than 250 msec. This contribution shows the architecture and design and gives an overview of the system as built and operated. It is based on commercial-off-the-shelf processing hardware at front-end level and on the CERN function generator design at equipment level. The system is self contained, permitting use of parts and the whole is other accelerators. Especially the separation of the power converter from the real-time regulation using CERN's Converter Regulation Board makes this approach an attractive choice for integrating existing power converters in new configurations.

  A software framework, called Internal Post Operation Check (IPOC), has been developed to acquire and analyse kicker magnet current waveforms. It was initially aimed at performing the surveillance of LHC beam dumping system (LBDS) extraction and dilution kicker current waveforms and was subsequently also deployed on various other kicker systems at CERN. It has been implemented using the Front-End Software Architecture (FESA) framework, and uses many CERN control services. It provides a common interface to various off-the-shelf digitiser cards, allowing a transparent integration of new digitiser types into the system. The waveform analysis algorithms are provided as external plug-in libraries, leaving their specific implementation to the kicker system experts. The general architecture of the IPOC system is presented in this paper, along with its integration within the control environment at CERN. Some application examples are provided, including the surveillance of the LBDS kicker currents and trigger synchronisation, and a closed-loop configuration to guarantee constant switching characteristics of high voltage thyratron switches.

  During the first 3 years of LHC operation, the priorities for the vacuum controls SCADA were to attend to user requests, and to improve its ergonomics and efficiency. We now have reached: information access simplified and more uniform; automatic scripts instead of fastidious manual actions; functionalities and menus standardized across all accelerators; enhanced tools for data analysis and maintenance interventions. Several decades of cumulative developments, based on heterogeneous technologies and architectures, have been asking for a homogenization effort. The Long Shutdown (LS1) provides the opportunity to further standardize our vacuum controls systems, around Siemens-S7 PLCs and PVSS SCADA. Meanwhile, we have been promoting exchanges with other Groups at CERN and outside Institutes: to follow the global update policy for software libraries; to discuss philosophies and development details; and to accomplish common products. Furthermore, while preserving the current functionalities, we are working on a convergence towards the CERN UNICOS framework.

MOPPC031 IEPLC Framework, Automated Communication in a Heterogeneous Control System Environment 139

  Programmable Logic Controllers (PLCs, PXI systems and other micro-controller families) are essential components of CERN control's system. They typically present custom communication interfaces which make their federation a difficult task. Dependency from specific protocols makes code not reusable and the replacement of old technology a tedious problem. IEPLC proposes a uniform and hardware independent communication schema. It automatically generates all the resources needed on master and slave side to implement a common and generic Ethernet communication. The framework consists of a set of tools, scripts and a C++ library. The JAVA configuration tool allows the description and instantiation of the data to be exchanged with the controllers. The Python scripts generate the resources necessary to the final communication while the C++ library, eventually, allows sending and receiving data at run-time from the master process. This paper describes the product by focusing on its main objectives: the definition of a clear and standard communication interface; the reduction of user’s developments and configuration time.

  The Detector Control System (DCS) of the ATLAS experiment at the LHC has been using the OPC DA standard as interface for controlling various standard and custom hardware components and their integration into the SCADA layer. Due to its platform restrictions and expiring long-term support, OPC DA will be replaced by the succeeding OPC Unified Architecture (UA) standard. OPC UA offers powerful object-oriented information modeling capabilities, platform independence, secure communication and allows server embedding into custom electronics. We present an OPC UA server implementation for CANopen devices which is used in the ATLAS DCS to control dedicated IO boards distributed within and outside the detector. Architecture and server configuration aspects are detailed and the server performance is evaluated and compared with the previous OPC DA server. Furthermore, based on the experience with the first server implementation, OPC UA is evaluated as standard middleware solution for future use in the ATLAS DCS and beyond.

  This paper presents the integration of a third industrial platform for process control applications with the UNICOS (Unified Industrial Control System) framework at CERN. The UNICOS framework is widely used in many process control domains (e.g. Cryogenics, Cooling, Ventilation, Vacuum…) to produce highly structured standardised control applications for the two CERN approved industrial PLC product families, Siemens and Schneider. The CoDeSys platform, developed by the 3S (Smart Software Solution), provides an independent IEC 6131-3 programming environment for industrial controllers. The complete CoDeSys based development includes: (1) a dedicated Java™ module plugged in an automatic code generation tool, the UAB (UNICOS Application Builder), (2) the associated UNICOS baseline library for industrial PLCs and IPCs (Industrial PC) CoDeSys v3 compliant, and (3) the Python-based templates to deploy device instances and control logic. The availability of this development opens the UNICOS framework to a wider community of industrial PLC manufacturers (e.g. ABB, WAGO…) and, as the CoDeSys control Runtime works in standard Operating Systems (Linux, W7…), UNICOS could be deployed to any IPC.

  The Paul Scherrer Institute builds, runs and maintains several particle accelerators. The proton accelerator HIPA, the oldest facility, was mostly equipped with CAMAC components until a few years ago. In several phases CAMAC was replaced by VME hardware and involved about 60 VME crates with 500 cards controlling a few hundred power supplies, motors, and digital as well as analog input/output channels. To control old analog and new digital power supplies with the same new VME components, an interface, so called Multi-IO, had to be developed. In addition, several other interfaces like accommodating different connectors had to be build. Through a few examples the upgrade of the hardware will be explained.

The current shutdown of the Large Hadron Collider (LHC), following three successful years of physics data-taking, provides an opportunity for major upgrades to be performed on the Detector Control System (DCS) of the Electromagnetic Calorimeter (ECAL) of the Compact Muon Solenoid (CMS) experiment. The upgrades involve changes to both hardware and software, with particular emphasis on taking advantage of more powerful servers and updating third-party software to the latest supported versions. The considerable increase in available processing power enables a reduction from fifteen to three or four servers. To host the control system on fewer machines and to ensure that previously independent software components could run side-by-side without incompatibilities, significant changes in the software and databases were required. Additional work was undertaken to modernise and concentrate I/O interfaces. The challenges to prepare and validate the hardware and software upgrades are described along with details of the experience of migrating to this newly consolidated DCS.

  TPS (Taiwan Photon Source) is a 3 GeV synchrotron light source which is being in construction at NSRRC. The TPS BPM is based on xTCA platform, is used for various request and function reasons. These functions will be discussed. Another purpose is for orbit feedback system. The tradition BPM electronic is separated from orbit feedback system, is just monitor. In the TPS, the orbit feedback system is embedded in the BPM crate with FPGA modules. High throughput backplane, data transfer and processing support rich function for waveform recorder, diagnostic, beam study and transient analysis. The implementation result of the BPM system will be reported in this conference.

The AMS (Accelerator Mass Spectrometry) project at ATLAS (Argonne Tandem Linac Accelerator System) complements the MANTRA (Measurement of Actinides Neutron TRAnsmutation) experimental campaign. To improve the precision and accuracy of AMS measurements at ATLAS, a new overall control system for AMS measurements needs to be implemented to reduce systematic errors arising from changes in transmission and ion source operation. The system will automatically and rapidly switch between different m/q settings, acquire the appropriate data and move on to the next setting. In addition to controlling the new multi-sample changer and laser ablation system, a master control program will communicate via the network to integrate the ATLAS accelerator control system, FMA control computer, and the data acquisition system.

The programmable spatial shaper (PSS) within the National Ignition Facility (NIF) reduces energy on isolated optic flaws in order to lower the optics maintenance costs. This will be accomplished by using a closed-loop system for determining the optimal liquid-crystal-based spatial light pattern for beamshaping and placement of variable transmission blockers. A stand-alone prototype was developed and successfully run in a lab environment as well as on a single quad of NIF lasers following a temporary hardware reconfiguration required to support the test. Several challenges exist in directly integrating the C-based PSS engine written by an independent team into the Integrated Computer Control System (ICCS) for proof on concept on all 48 NIF laser quads. ICCS is a large-scale data-driven distributed control system written primarily in Java using CORBA to interact with +60K control points. The project plan and software design needed to specifically address the engine interface specification, configuration management, reversion plan for the existing 0% transmission blocker capability, and a multi-phase integration and demonstration schedule.

The communication framework for the in-house controls system in the Collider-Accelerator Department at BNL depends on a variety of hardware interfaces and protocols including RS232, GPIB, USB and Ethernet to name a few. IISC is a client software library, which can be used to initiate, communicate and terminate data exchange sessions with devices over the network. It acts as a layer of abstraction allowing developers to establish communication with these devices without having to be concerned about the particulars of the interfaces and protocols involved. Details of implementation and a performance analysis will be presented.
