  EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from modulator and undulator communication and control, over motion control, basic I/O control, all the way to Machine Protection System for the new SwissFEL accelerator. A combined EPICS/Linux driver package has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The driver is capable of automatic scan of the existing devices and modules, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. Additionally, the driver package supports the user PLC to manipulate EtherCAT data in real time, implements fast real-time (single cycle) slave-to-slave communication (skipping EPICS layer or PLC completely), features guaranteed one-shot trigger signals otherwise not supported by EPICS and much more. All the standard EtherCAT functions are supported, including the complete reprogramming of slave configurations and configuration generation for programmable slaves, such as EL6692 and EL6695 network bridges.

  BLISS is the new ESRF control system for running experiments, with full deployment aimed for the end of the EBS upgrade program in 2020. BLISS provides a global approach to run synchrotron experiments, thanks to hardware integration, Python sequences and an advanced scanning engine. As a Python package, BLISS can be easily embedded into any Python application and data management features enable online data analysis. In addition, BLISS ships with tools to enhance scientists user experience and can easily be integrated into TANGO based environments, with generic TANGO servers on top of BLISS controllers. BLISS configuration facility can be used as an alternative TANGO database. Delineating all aspects of the BLISS project from beamline device configuration up to the integrated user interface, this poster will present the technical choices that drove BLISS design and will describe the BLISS software architecture and technology stack in depth.

  At the National Synchrotron Light Source II (NSLS-II) there are many different ultra-high vacuum system configurations on the unique beamline end-stations. The proposed controls solution attempts to capture the requirements of all of these configurations with a single standard logic and graphical user interface. Additional design considerations include: resource management for multiple users, providing a high level of abstraction to simplify operation for users, providing a high level of flexibility to do non-standard operations, minimizing shock from pressure differentials when opening valves, supporting a variety of pumps, and maximizing pump lifetime. At NSLS-II it was determined that all vacuum configurations can be captured by the composition of three standard objects: a "rough vacuum group", and "high vacuum group", and a "smart vacuum manifold" which implements a blocking queue. These objects can be flexibly linked together to meet the needs of the beamline experiments. This solution is platform independent, but implemented and tested here using Pfeiffer vacuum pumps, Allen Bradley PLC, EPICS, and Control System Studio (CSS).

  The industrial control systems of CERN's experiments are undergoing major renovation since 2017 and well into CERN's second Long Shutdown (LS2) until the end of 2019. Each detector power-supply control system runs several hundred software instances consisting of many different components in parallel on a large scale, broadly distinguishable as servers and clients. Our accumulated experience during LHC runs proves that some complex control issues are impossible to detect using stand-alone components on a small scale only. Furthermore, new components must be developed well before the electron-ics becomes available, without impact on operations. Moreover, during LS2, the improved and now widely established Open Protocol Communication Unified Ar-chitecture (OPC-UA) replaces OPC-DA as middleware protocol. For these reasons, we developed a simulation environment to emulate the real, and valuable, CAEN power-supply electronics underneath the OPC-UA serv-ers. This distributed simulation is configurable to mimic and exceed the nominal conditions during production and provides a repeatable setup for validation. This paper discusses the functionality and use of this simulation service.

An Infrared Free Electron Laser Light (IRFEL) is being constructed at National Synchrotron Radiation Laboratory. The EPICS Archiver Appliance provides the functions of historical data acquisition, archiving, migration, retrieval and management in the IRFEL facility. A Single-Page Web Application is developed for the data visualization based on Vue.js framework and Highcharts JavaScirpt library. A unified interface is developed for the visualization to integrate multiple data sources and provide the same retrieval entry of the historical data from EPICS Archiver Appliance, the real-time data from EPICS IOC, the statistical data from database and the alarm information from the Phoebus. This paper will describe the implementation details of data archiving and visualization of IRFEL.

  GUI for supervision, control and data acquisition systems are usually oriented to specialist users. In big organizations like CERN, where different teams play the roles of operators, scientists and instrumentation specialists, providing a unique or static user interface usually results in a situation of dissatisfaction of everyone. On the other hand, providing distinct user interfaces for each type of user increases the development and maintenance effort and makes software evolution heavier. The approach taken for the design and development of GUIs for radiation and environment protection at CERN addressed this issue by integrating user interface changes as an embedded software functionality. Key users were provided with a tool to build, deploy and maintain their own tailor-made user interfaces, in a graphical way and without the necessity of learning any kind of programming or scripting languages. Other benefits observed from this solution include reduction of the resources spent on the support and maintenance and increase of the frequency of GUIs updates, executed without compromising the underlying control system. This paper describe the innovative design that was implemented.

  One of the heaviest workloads when installing a Control System on a plant is the development of a large number of device drivers. This is even more true in the case of scientific facilities for which you typically deal with many custom devices and legacy code. In these cases, it is useful to consider the Rapid Application Development (RAD) approach that consists in lessen the planning phase and give more emphasis on an adaptive process, so that software prototypes can be successfully used in addition to or in place of design specifications. LabVIEW* is a typical RAD-oriented development tool and is widely used in technical laboratories where many stand-alone programs are developed to manage devices under construction or evaluation. An original system that allows software clients to use external LabVIEW drivers is presented. This system, originally created for the !CHAOS Control System**, is entirely written in LabVIEW and is based on JSON messages -transmitted on a WebSocket communication- driving LabVIEW VIs through dynamic calls. This system is completely decoupled from the client and is therefore suitable for any Control System.

  The main driving part of the X-ray free electron laser facility (SwissFEL) at the Paul Scherrer Institute (PSI) is a compact electron linear accelerator (linac). The machine is highly optimized to generate a superior FEL radiation with the lowest suitable electron beam energy. In order to meet extremely stringent SwissFEL requirements for electron beam quality and stability, a variety of beam diagnostics tools were developed and implemented at the PSI. All these tools are integrated into the SwissFEL control system. The paper describes basic control elements of the electron beam diagnostics tools and their operational performance.

  Fixed field alternating gradient (FFAG) accelerator complex has been operated as a proton driver for the experiment of accelerator driven system (ADS) at Institute for Integrated Radiation and Nuclear Science, Kyoto University (KURNS)*.  PLC based control system has been developed and the operator interface has been connected to PLC via network. Originally, a LabVIEW based operational interface was chosen to construct the system because of its easiness. However we met an upgrade problem, and a new control system based on EPICS instead of LabVIEW was introduced in 2010. In the spring of 2018, the replacement from LabVIEW to EPICS has been almost completed except for the beam interlock system and the LINAC control system provided by LINAC production company (AccSys). Also, the EPICS archiving tool (Archiver Appliance) has been invoked and operated at the end of 2017. This Presentation reports the details of the current control system and also the upgraded GPIB control and storage system.

  The Taiwan Photon Source (TPS) is a 3 GeV storage ring. A NI C-RIO controller, basic to the real-time, EPICS program, is used and designed such as to maintain ultra-high vacuum conditions and protect vacuum components. Pressure readings from ionization gauges are taken as the logic signal to control sector gate valves to protect ultra-high vacuum condition. Monitoring of vacuum components, water-cooling systems and chamber temperatures serves to protect vacuum equipment from radiation power. The evolution and status of the control system is presented in this paper.

  We report on development of the successor of the existing controller device used for the magnet power supplies in the RIKEN Radioactive Isotope Beam Factory (RIBF). The existing controller for the magnet power supplies is operated in the Versa Module European (VME) computing machines under the Experimental Physics and Industrial Control System (EPICS) framework. The present controller has been operated stably for more than 10 years, however, it is now commercially unavailable because supply of some parts has been already terminated. In 2016, we developed a successor to have the same function essentially as the existing one, but it is designed to run in control systems constructed by programmable logic controller (PLC) modules instead of the VME computing environment, in order to achieve cost reduction and functional scalability. We confirmed that the successor was successfully controlled by using a test system. And now, we are developing a control system that can flexibly add new functions through actual operation while having all the existing functions. We will introduce the successor to the new injector LINAC system this year.

The Electromagnetic Calorimeter (ECAL) is one of the detectors of the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC). The ECAL Detector Control System (DCS) software has been implemented using the WinCC Open Architecture (OA) platform. Modifications that require fundamental changes in the architecture are deployed only during the LHC long shutdowns. The upcoming long shutdown (2019-2020) offers a unique opportunity to perform large software updates to achieve a higher modularity, enabling a faster adaptation to changes in the experiment environment. We present the main activities of the ECAL DCS upgrade plan, covering aspects such as the re-organization of the computing infrastructure, the consolidation of integration tools using virtualized environments and the further usage of centralized resources. CMS software toolkits are evaluated from the point of view of the standardization of important parts of the system, such as the machine protection mechanism and graphical user interfaces. Many of the presented features are currently being developed, serving as precursors to the major ECAL upgrade foreseen for the next long shutdown (~2024-2025).

The CMS Detector Control System (DCS) is implemented as a large distributed and redundant system, with applications interacting and sharing data in multiple ways. The CMS XML-RPC is a software toolkit implementing the standard Remote Procedure Call (RPC) protocol, using the Extensible Mark-up Language (XML) and a custom lightweight variant using the JavaScript Object Notation (JSON) to model, encode and expose resources through the Hypertext Transfer Protocol (HTTP). The CMS XML-RPC toolkit complies with the standard specification of the XML-RPC protocol that allows system developers to build collaborative software architectures with self-contained and reusable logic, and with encapsulation of well-defined processes. The implementation of this protocol introduces not only a powerful communication method to operate and exchange data with web-based applications, but also a new programming paradigm to design service-oriented software architectures within the CMS DCS domain. This paper presents details of the CMS XML-RPC implementation in WinCC Open Architecture (OA) Control Language using an object-oriented approach.

A compact electron-accelerator based neutron source/facility for the characterization of structural materials is under construction by the Innovative Structural Materials Association (ISMA) at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan. The facility consists of a linear electron accelerator (LINAC) with a planned maximum beam power of 10 kW (~35 MeV, ~275 mA) incident on a water cooled tantalum target. The LINAC will be primarily controlled from a control room outside the radiation control area. It is also planned that a full monitoring system and some control functionality will also be available at the neutron beamline hall. We plan to install a control and monitoring system using the EPICS framework. A separate interlock system for the facility is also being developed and installed. The interlock system uses a commercial PLC sequencer in combination with a newly developed serial bus communication system developed at AIST. Both the EPICS and interlock systems will be presented in more detail at the conference.

  The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine and efficient online data display and analysis were determining criteria, but also the seamless integration of many different platforms and programming languages. Although there has been continuous development and improvement during the operation of PETRA, it has now been 10 years since the last major release (version 4). Introducing a new major release necessarily implies a restructuring of the protocol headers and a tacit guarantee that it be compatible with its predecessors, as any logical deployment and upgrade strategy will entail operating in a mixed environment. We report here on the newest features of TINE Release 5.0 and on first experiences in its initial deployment.

  The IFMIF prototype accelerator, LIPAc, aims at producing a powerful (9MeV, 1.1MW) deuteron beam at 125mA in CW, to validate the concept for the future IFMIF (40MeV, 125mA CW). The beam will go through two main accelerating stages (RFQ and SRF Linac), plus two bunching cavities as part of the MEBT. These require continuous wave RF power at 175 MHz for the 18 RF power sources feeding the eight RFQ couplers (200kW), the two buncher cavities (16kW) and the eight superconducting half wave resonators of the SRF Linac (105kW). The functionality of the LLRF has been complemented with python based automatic rearming tool to resume RF power automatically in case of safe interlocks in order to optimise the RFQ conditioning process. The rearming tool is communicating with EPICS using pyEPICS module, and it is running on central control system (CCS) and is interfacing the RF power system (RFPS) through EPICS.

  The Photo Injector Test Facility at DESY in Zeuthen (PITZ) was built to test and to optimize sources of high brightness electron beams for Free-Electron Lasers (FELs). In order to achieve high accelerating gradients and long RF pulse lengths in the RF gun cavities an extensive and safe RF conditioning is required. A State Machine based Automatic Conditioning application (SMAC) was developed to automate the RF conditioning processes, allowing for greater efficiency and performance optimization. SMAC is written in Java and uses State Chart XML (SCXML) as the finite-state machine execution environment based on Harel statecharts. It employs the Distributed Object-Oriented Control System (DOOCS) and Three-fold Integrated Networking Environment (TINE) for the communication with the control system of PITZ. The graphical user interface (GUI) is created by using the Java Swing toolkit. Communication between GUI and SXML processing layer is performed via Document Object Model (DOM) events. The SMAC application has been successfully applied to RF conditioning of several gun cavities at PITZ.

  The Photon Factory is an accelerator-based light source facility, as a part of the High Energy Accelerator Research Organization (KEK) Japan and STARS (Simple Transmission and Retrieval System) is used as the beamline control system at the Photon Factory. STARS is a message transferring software for small scale control systems with TCP/IP sockets, which works on various types of operating systems. STARS is effective for various control systems and we developed Vacuum Gauge Monitoring and Control System with STARS. Web2cToolkit is developed by DESY that provides a user-friendly interface and user can develop Web based GUIs easily with Web2cToolkit. Web2c supports various types of protocol (e. g. TINE, DOOCS, EPICS, TANGO etc.) and the STARS protocol has been supported. We decided to introduce Web2cToolkit as the GUI application on our vacuum gauge monitoring and control system and a few functions are implemented. The development is still in progress.

  In 2007, the creation of the electron-positron collider VEPP-2000 was completed at the Institute of Nuclear Physics of the SB RAS. VEPP-2000 collider facility consists of various subsystems, and a failure of any subsystem can lead to the incorrect operation of the complex for several hours or even days. Thus, there is a need to create software that, based on the data analysis, will warn about possible malfunctions. To accomplish the task, software was developed consisting of three modules. The first performs automatic verification of compliance data obtained from the accelerator complex and rules describing the correct subsystems operation. The second module is a user-friendly web interface that displays information about the state of the complex in a convenient way. The third module acts as some intermediary between the first and the second. It processes messages arriving at the message queue and redirects them to all subscribed clients via the web socket. This article is devoted to the development of test software, which is currently running on the VEPP-2000 control panel.

  The VEPP-2000 is an electron-positron collider, that was commissioned at Budker Institute of Nuclear Physics. The VEPP-2000 acceleration complex consists of a few main subsystems: BEP booster ring and VEPP-2000 collider ring. Data from accelerator complex are recorded regularly with a frequency at 1 Hz. There is often a need to obtain already stored data for analysis or modeling. In addition, you must provide remote data access to optimize the workflow. The solution of this problem must be universal, and it must be easily adapted to various databases and installation modes. To solve the task, the software was developed based on the client-server architecture. The server part is responsible for processing data in automatic mode according to the developed algorithm. The client part allows to view the data in a user-friendly form. This article talks about the development of software, simplifying access to the VEPP-2000 archiving system, that is launched on the VEPP-2000 control panel.

  In RIBF project, a superconducting linac will be implemented in order to enhance the beam energy necessary for promoting super heavy element experiment. A new 28 GHz electron resonance ion source has been installed upstream of them. Its control system will be consisted of Yokogawa FA-M3 series which is a porgrammble logic controller (PLC) with EPICS because of many achievements in case of RIBF control system. On the other hand, in the previous system with PLCs there was a disadvantage of low reliability for communications between PLC stations. Additionally, some devices (eg, oven, mivoc etc.) are changed for the generation of various kind of ions each times, therefore higher expandability is required. In the new system, we have designed the control system by utilizing star topology fieldbus for communications between the PLC stations to establish safety and expandability. In this conference, we report on the details of the system.

  In the design of the ADS injector II, the RFQ cavity holds a supreme status, and the RFQ temperature and flow information are the key parameters for the cavity frequency tuning. To ensure the long-term, stable and accurate acquisition of temperature flow data is the core task of control. In this paper, the PLC temperature flow acquisition system which is based on EPICS design was described, and the EPICS driver of this PLC was developed independently. The driver uses TCP/IP connection to EPICS IOC, and the communication protocol uses the "data block overall transmission protocol", to ensure the stability of the device's data communications. After 3 months of long-term operation inspection, this acquisition system can ensure long-term and stable acquisition of real-time temperature and flow data of the equipment, and be able to send control information to related controlled equipment. In addition, redundant PLCs and redundant IOCs were adopted in this acquisition system to make the switch to alternate channels within milliseconds once a channel fails.

  As one of the major components of ADS Injector II, SRF (Superconducting Radio Frequency) cavities are used to transmit the intense-beam proton reliably, stably and efficiently. Before starting the process of transmitting particle beams, SRF cavities are routinely conditioned to achieve its optimized status in the deliverable energy. The whole conditioning process is involved in various types of hardware devices and is also a heavy task for engineers to manually operate these equipment. In this paper, the software ANSC is presented in details, which is used to automatically condition SRF cavities. At the present, ANSC is in the stage of testing. During the testing, ANSC indeed can achieve comparative results compared with manually operated conditioning.

  Building a high power spallation target is one of the critical issues in Accelerator Driven System (ADS). The control system which was built based on the real-time distributed control software of experimental physics and industrial control system (EPICS) was attempted for the experimental target prototype. There are several sub-systems in the target system, e.g. the elevating system, the vacuum system, the heat-exchanging system. As an IOC, each sub-system was finally integrated into the control system of the target by different drivers and methods because different hardware devices were used for each sub-system. The 'SLS s7 driver' which was devel-oped based on the Ethernet Interface was used for the communication between the Siemens PLCs and the Hu-man Machine Interface (HMI). The interfaces between Labview and EPICS were used for the NI (Nation-al Instruments) DAQs systems. In addition, the driver developed by ourselves was used for devices with serial ports, e.g. RS-232 or RS-485/422. The control system was finally proved stable and could basically meet the ele-mentary requirements of the spallation target system.
