WECC02 | EPICS Channel Access Using WebSocket | EPICS, controls, GUI, ECRIS | 7 |
|
|||
Web technology is useful as a means to widely inform of accelerators and beam status. For this purpose, WebOPI[1] as to web-based system using Ajax (Asynchronous JavaScript and XML) with EPICS was implemented by SNS. On the other hand, it is often necessary to perform the accelerator control from various locations as well as central control room during the beam operation and the maintenance. However, it is not realistic to replace GUI-based operator interface (OPI) with Web-based system using Ajax technology because of interactive performance. Therefore, as a next-generation OPI over the web using EPICS Channel Access (CA), we developed a client system based on WebSocket, which is a new protocol provided by Internet Engineering Task Force for Web-based system. WebSocket is a web technology providing bi-directional, full-duplex communication channels over a single TCP connection. By utlizing Node.js and WebSocket access library named Socket. IO, a WebSocket server was implemented. As a result, Web-based client systems became available not only in the central control room but also with various types of equipment for accelerator operation.

WEPD03 | Control System Studio Archiver with PostgreSQL Backend: Optimizing Performance and Reliability for a Production Environment | controls, EPICS | 15 |
|
|||
Funding: Supported by DFG through CRC 634. Archiving systems based on relational databases (RDB) provide a higher flexibility with regard to data retrieval and analysis than the traditional EPICS Channel Archiver. On the other hand they can suffer from poor performance compared to the Channel Archiver for simple linear data retrieval operations. However, careful tuning of the database management system's configuration can lead to major performance improvements. Special care must be taken to ensure data integrity following power outages or hardware failures. This contribution describes the hardware and software configuration of an archiving system used in the production environment at the S-DALINAC. It covers performance and reliability aspects of the hardware as well as tuning of the Linux operating system and PostgreSQL server optimizations. |

WEPD25 | Development of EPICS Channel Access Embedded ActiveX Components for GUI Development | controls, GUI, EPICS, heavy-ion | 54 |
|
|||
The paper describes the integration of EPICS Channel Access protocol and Microsoft ActiveX technology towards developing a generalize operator interface (OPI) building facility for Windows platform. EPICS is used as the development architecture of the control system in Superconducting Cyclotron (SCC). Considering the operators' familiarity and compatibility with third party software, it was decided to use MS-Windows platform at operator interface level in SCC during commission. Microsoft Visual Basic (VB) is used on trial basis as OPI building platform to incorporate user specific features e.g. file system access for data storage and analysis, user authentication at OPI level etc. A set of EPICS Channel Access embedded ActiveX components is developed to ease the programming complexity and reduce developmental time of the OPI for Windows platform. OPIs, developed using these components and containing hundreds of process parameters, are being used reliably over a considerable period of time. | |||

WEPD28 | Re-envisioning the Operator Consoles for Dhruva Control Room | controls, status, laser, acceleration | 62 |
|
|||
Control Room design is undergoing rapid changes with the progressive adoption of computerization and automation. Advances in man-machine interfaces have further accelerated this trend. This paper presents the design and main features of Operator consoles (OC) using new technologies for Dhruva control room. The OCs have been designed so as not to burden the operator with information overload but to help him quickly assess the situation and timely take appropriate steps. The consoles provide minimalistic yet intuitive interfaces, context sensitive navigation, display of important information and progressive disclosure of situation based information. The use of animations, 3D graphics, and real time trends with the benefit of hardware acceleration to provide a resolution-independent rich user experience. The use of XAML, an XML based Mark-up Language for User Interface definition and C# for application logic resulted in complete separation of visual design, content, and logic. This also resulted in a workflow where separate teams could work on the UI and the logic of an application. The introduction of Model View View-Model has led to more testable and maintainable software. | |||

THIA03 | The IUAC Tandem-LINAC Control System | controls, linac, GUI, ion | 94 |
|
|||
The 16MV Tandem Van de Graff accelerator at IUAC is one of the earliest machines to go for a PC based control system. The PDP11, supplied with it, was replaced by an IBM PC running DOS before the accelerator was commissioned in 1989. The present system, commissioned in 1997 to include the LINAC, runs on a network of PCs under the GNU/Linux operating system. We have followed a distributed approach by grouping the signals, around 1000 in total, based on the location. Each group is connected to a server computer, by hardware interfaces like CAMAC, VME and custom hardware. The signals connected to each server PC are handled by a server program and they are accessible to the outside world, over a TCP/IP network, using a unique identifier consisting of a Label, Function and Unit. The features like a user interface, monitoring for alarm conditions, data logging and partial automation are handled by several client programs, communicating to multiple servers to access the hardware. The communication is done by passing a message packet and waiting for the reply. The message consists of the unique signal identifier and commands for setting/reading analog and digital parameter values. The development of the control system also resulted in low cost equipment for science education[1]. It also helped further development of the control system by additions like client programs in Python language. This feature enabled accelerator users to write simple scripts for tasks like setting the LINAC resonator parameters based on calculations, writing routines for partial automation etc. The system is cost effective, scalable and simple. It has shown very high reliability and ease of use during the past two decades of operation.

THCA06 | Status of the Ultra Fast Tomography Experiments Control at ANKA | controls, synchrotron, optics, HOM | 103 |
|
|||
X-ray imaging permits spatially resolved visualization of the 2D and 3D structure in materials and organisms which is crucial for the understanding of their properties. Additional resolution in the time domain gives insight in the temporal structure evolution and thus access to dynamics of processes allowing to understand functionality of devices and organisms and to optimize technological processes. Such time resolved dynamic analyses ofμsize structures became now possible by the new ultrafast tomography at the TopoTomo beamline of the synchrotron light source ANKA. At TopoTomo the whole experimental workflow has been significant improved in order to decrease the total duration time of a tomography experiment in a range of minutes. To aim the goal of a Tango based control system for ultra fast tomography with a data throughput of several 100 MB/s, detectors and computing infrastructure have been optimized. Multi GPU based computing allows a high speed data processing by using a special reconstruction scheme. Furthermore data management infrastructure will allow a life cycle management of data sets accumulating to several TByte/day. | |||

THCC02 | Controls Architecture for the Diagnostic Devices at the European XFEL | controls, diagnostics, site, electron | 121 |
|
|||
The X-ray laser is an 3.4-km-long facility which runs essentially underground and comprises three sites above ground. For controlling all diagnostic devices like toroids, BPMs or BLMs, it is planned to use the new MTCA.4 crate standard instead of VME. ATCA is an emerging standard from the Telecom Industry and adapted with the PICMG MTCA.4 branch for physics usage. The communication on the backplane utilizes the high speed serial PCIe communication plus precise clock lines and SATA interface. The MTCA.4 hardware supports hot-plug mechanism and remote monitoring and control via IPMI over Ethernet. Some of the diagnostics will be connected to 16Bit ADCs with up to 125Mhz sampling rate from Struck company or to an internal DESY development call DAMC2. The software architecture is based on the DOOCS control system known from the FLASH accelerator. The raw data from the ADCs will be read via DMA transfer by one server process. Then this raw data will distributed locally on the CPU using a message passing system based on the ØMQ project. The receiving server processes are calculating these data into engineering units then. Everything works in an event driven way. | |||

THCC03 | PC Based Real Time Data Exchange on 10GbE Optical Network Using RTOS | controls, status | 124 |
|
|||
Funding: This work is supported by research grant No. BRFST/NFP/2012/Feb/N/05; dated 5th April, 2012, under the National Fusion Programme of the Board for research in Fusion Science & Technology at IPR The traditional embedded systems are expensive to adapt to the new requirements. The Personal Computer based systems offer alternatives for industrial controls. It reduces the capital cost and provides a solution for multiple applications. However, limitations of PC based controls should be resolved. PC operates on a non-real time OS with non-deterministic response to real time events and data. The real-time pre-emptive kernel for Linux uses Xenomai for better solution. A real-time 10GbE data exchange optical network using Xenomai extension for Linux is demonstrated. The hardware based on Intel_82599 10GbE Ethernet PCIe network card supports IEEE1588 standard for synchronization, deterministic response to real-time interrupts and events. The benchmark testing comprises multiple nodes and data sources, for data exchange among nodes, which would improve the performance of PC control systems. Data sources and consumers include time synchronization, hardware and software events broadcasting. A single fiber cable is used for exchange of measured status and calculated control data among nodes. Moreover, the open source Ubuntu Linux RTOS will help the future development.

THCD06 | Design Development and Analysis of a Comprehensive Open Source System for Proactive Management of Security Aspects of a Control Network | controls, status, factory | 134 |
|
|||
Control networks can only be assumed to be secure, when they work in complete isolation and all communication ports of the constituent control devices are disabled and are closely monitored for security breaches on 24X7 basis. With more and more control systems being developed using Common Out of The Shelf (COTS) computers, using windows OS, the chances of virus attacks on such control networks is extremely large. Handling zero day virus attacks or virus attacks with unknown cure, is a serious challenge for control network administrators. Another important aspect, somehow related to the security of the control network, is the rising temperatures of the control devices, because of 24X7 operation. All this is difficult to handle manually or using disconnected systems and hence there is a requirement of a comprehensive system which can do all this automatically. In this paper we will discuss the various security related parameters of the control networks and then present a simplified design followed by development details of a comprehensive open source system for proactive management of the security aspects of the control network. | |||

THPD09 | Development of a Monitoring System for the FL-net Protocol | controls, PLC, status, undulator | 151 |
|
|||
At SPring-8 and SACLA, we are using the FL-net for many control systems as a communication protocol between front-end computers and PLCs. The FL-net is one of the Ethernet-based open standard protocols for a factory floor network authorized by the Japan Electrical Manufacturers' Association. It is a UDP/IP based master-less token passing protocol and supports a cyclic transmission. At SACLA, we had some troubles in a data acquisition by using the FL-net for beam line equipment protection system. In a network based control system, an analysis of network packets is an effective way at troubleshooting. We developed a monitoring system for the FL-net protocol, which captures and analyzes all packets of an FL-net network segment, detects protocol failure events, and stores the event information into a relational database. We can easily refer to the stored information in the database via a web browser. The monitoring system is highly portable software based system without dedicated hardware implementing a protocol stack. In this paper, the design of the monitoring system for the FL-net will be presented. | |||

ZigBee based wireless technology is used to provide a low cost, low power, secured, PAN solution for monitoring of parameters from several distributed vacuum pumping modules installed in the SCC injection line. The parameters include On-Off status of the modules, RPM of pump, input current and pressure reading of different vacuum gauges. The ZigBee stack is written in a simplified form so that each node can create a network and can join to any established network when powered on. End nodes can be replaced through a little modification in the firmware codes. End node consists of sensors, signal conditioning circuits, micro-controller and ZigBee Transceiver whereas the central node consists of micro-controller, Transceiver and UART interface. This paper highlights the future approach of utilizing this network for data acquisition related with environmental temperature, relative humidity, noise, water leakage from inaccessible areas of Cyclotron Vault, Pit, Basement and ECR Highbay for the ease of maintenance also demonstrate the development of an environment monitoring system powered by solar cells covering a wide area. | |||

|
|||
The control system software needed for operation of Indus accelerators is interfaced to the underlying firmware and hardware of the control system by the Application Programming Interface (API) manager. PVSS-II SCADA is being used at the layer-1 (L1) for control and monitoring of various sub-systems in the three-layered architecture of Indus control system. The layer-2 (L2) consists of VME bus based system. The API manager plays a crucial role in interfacing the L1 and L2 of the control system. It has to interact with both the PVSS database and the L2. It uses the PVSS API, a C++ class library, to access the PVSS database, whereas in order to access the L2, custom functions have been built. Several other custom functionalities have also been implemented. This paper presents the important aspects of the API manager like its implementation, its interface mechanism to the lower layer and features like configurability, reusable classes, multithreading capability etc. | |||

Funding: Science & Technology Facilities Council, UK Computerised controls are vital to the operability and flexibility of large-scale physics facilities (such as accelerators, synchrotrons and high-power lasers) in providing fundamental services, for example, automatic configuring of specialist hardware, motion control, firing of shot sequences, enabling precision trigger distribution, vacuum monitoring and control, data acquisition and analysis. The proposed 10PW Laser facility, in line with other major physics facilities around the world, will require a complex computer control system. This is expected to be modeled on the existing Vulcan Laser[1] control system and consist of a dozen or so Windows based PCs each of which will be running a separate and dedicated application to control a particular area or function of the facility. This paper will present an overview of the existing Vulcan laser and provide a status report on the development towards the 10PW which will require the control system to be designed to allow autonomous operation of the 10PW facility as well as to be fully integrated with the existing Vulcan laser controls for combined and synchronized 10PW plus 1PW operations.

|
|||
Funding: RRCAT, Indore, Department of Atomic Energy, Government of India This paper describes a distributed embedded system that uses a high performance mixed signal controller C8051F040 for its DAQ nodes and is based on CAN bus protocol for remote monitoring and controlling of various subsystems of 750 keV DC accelerator based irradiation facility at RRCAT, Indore. A PC with integrated PCI CAN card communicates with intelligent DAQ nodes over CAN bus and each node is interfaced with a subsystem. An opto- isolated SN65HVD230 CAN driver is interfaced between each node and physical bus. Remote frames and message prioritizing are used for efficient control. The PC application is developed using LabVIEW 8.6. The proposed system is more reliable and noise immune as compared to previously [1] used systems that initially used a centralized system based on C8051 controller. This was then upgraded [2] to a distributed system that used micro-controller AduC812 and communicated over RS485 link. The new system has been integrated and tested satisfactorily for its designed performance with test jigs that simulated the actual subsystems with a bus length of 75 meters. First the complete scheme of the system is presented, then the hardware and software designs are discussed. [1] A.

Funding: ESS Bilbao Although EPICS is a mature software framework, the study and validation of new configurations of EPICS systems is very valuable, since new ideas open its evolution and improvement. So, the goal of the present work is to introduce new technologies under EPICS control structures and test different configurations with innovative hardware in this kind of applications. More specifically, it is intended to validate the use of non-stardard EPICS controllers. This paper presents a test bench using LabVIEW together with EPICS. LabVIEW eases and speeds up the development of control structures, avoids the hardware dependent developing costs and offers almost absolute compatibility with all kind of hardware used in control and data acquisition. To validate its use, it is mandatory to make a study facing this solution and EPICS standard methodology, specifically CODAC system used in ITER. To do so, a test bench is defined running both methods and its results compared. Following this scheme, the next step is to make a similar experiment introducing wireless links and replacing as many wires as possible. |

Funding: Swiss National Science Foundation (SNF) The sub-detectors of the Compact Muon Solenoid (CMS) multi-purpose particle detector at the CERN Large Hadron Collider (LHC) have been collecting physics data from particle collisions for almost three years. During this period, the Electromagnetic Calorimeter (ECAL) Detector Control System (DCS) has contributed to the high level of availability of the experiment. This paper presents the current architecture of this distributed and heterogeneous control system alongside plans and developments for future improvements. To ensure that the system can efficiently operate and adapt to changes throughout the required operation lifetime of more than a decade, the potential legacy aspects of this kind of control system must be carefully managed. Such issues include evolving system requirements, turnover of staff members, potential benefits from new technologies and the need to follow release schedules of external software dependencies. The techniques and results of the work to continually maintain, improve and streamline the control system are presented, including the use of metrics to evaluate the impact of this effort. |
