	Funding: Authored by Jefferson Science Associates, LLC under U.S. DOE Contract No. DE-AC05-06OR23177. The U.S. Government retains a non-exclusive, paid-up, irrevocable, world-wide license to this manuscript. A new hot checkout process was implemented at Jefferson Lab for the upgraded 12 GeV accelerator. The previous process proved insufficient in the fall of 2011 when a fire broke out in a septa magnet along the beam line due to a lack of communication about the status of systems. The improved process provides rigorous verification of system readiness thus protecting property while minimizing program delays. To achieve these goals, a database and web application were created to maintain an accurate list of machine components and coordinate and record verification checks by each responsible group. The process requires groups to publish checklists detailing each system check to encourage good work practice. Within groups, the process encourages two independent checks of each component: the first by a technician, and a second by the group leader. Finally, the application provides a dashboard display of checkout progress for each system and beam destination of the machine allowing for informed management decisions. Successful deployment of the new process has led to safe and efficient machine commissioning.

MOPGF145	Commissioning and Design of the Machine Protection System for Fermilab's Fast Facility	controls, laser, interface, electron	428
	L.R. Carmichael, D.J. Crawford, N. Liu, R. Neswold, A. Warner, J.Y. Wu Fermilab, Batavia, Illinois, USA
	The Fermilab Accelerator Science and Technology (FAST) Facility will provide an electron beam with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 300 MeV beam energy. The completed machine will be capable of sustaining an average electron beam power of close to 15KW at the bunch charge of 3.2nC. A robust Machine Protection System (MPS) capable of interrupting the beam within a macro-pulse and that interfaces well with new and existing controls system infrastructure has been developed to mitigate and analyze faults related to this relatively high damage potential. This paper describes the component layers of the MPS system, including a FPGA-based Permit Generator and Laser Pulse Controller, the Beam Loss Monitoring system design as well as the controls and related work done to date.

WEM304	Status Monitoring of the EPICS Control System at the Canadian Light Source	controls, EPICS, network, database	667
	G. Wright, M. Bree CLS, Saskatoon, Saskatchewan, Canada
	The CLS uses the EPICS Distributed Control System (DCS) for control and feedback of a linear accelerator, booster ring, electron storage ring, and numerous x-ray beamlines. The number of host computers running EPICS IOC applications has grown to 200, and the number of IOC applications exceeds 700. The first part of this paper will present the challenges and current efforts to monitor and report the status of the control system itself by monitoring the EPICS network traffic. This approach does not require any configuration or application modification to report the currently active applications, and then provide notification of any changes. The second part will cover the plans to use the information collected dynamically to improve upon the information gathered by process variable crawlers for an IRMIS database, with the goal to eventually replace the process variable crawlers.

WEM308	A Multi-Modal Human-Machine-Interface for Accelerator Operation and Maintenance Applications	controls, operation, interface, vacuum	677
	R. Bacher DESY, Hamburg, Germany
	The advent of advanced mobile, gaming and augmented reality devices provides users with novel interaction modalities. Today's accelerator control applications do not provide features like speech, finger and hand gesture recognition or even gaze detection. Their look-and-feel and handling are typically optimized for mouse-based interactions and are not well suited for the specific requirements of more complex interaction modalities. This paper describes the conceptual design and implementation of an intuitive single-user, multi-modal human-machine interface for accelerator operation and maintenance applications. The interface seamlessly combines standard actions (mouse), actions associated with 2D single/multi-finger gestures (touch sensitive display) and 3D single/multi-finger and hand gestures (motion controller), and spoken commands (speech recognition system). It will be an integral part of the web-based, platform-neutral Web2cToGo framework belonging to the Web2cToolkit suite and will be applicable for desktop and notebook computers, tablet computers and smartphones, and even see-through augmented reality glasses.

	Funding: Swiss National Science Foundation (SNSF). The Detector Control System (DCS) of the Compact Muon Solenoid (CMS) experiment ran with high availability throughout the first physics data-taking period of the Large Hadron Collider (LHC). This was achieved through the consistent improvement of the control software and the provision of a 24-hour expert on-call service. One remaining potential cause of significant downtime was the failure of the computers hosting the DCS software. To minimize the impact of these failures after the restart of the LHC in 2015, it was decided to implement a redundant software layer for the control system where two computers host each DCS application. By customizing and extending the redundancy concept offered by WinCC Open Architecture (WinCC OA), the CMS DCS can now run in a fully redundant software configuration. The implementation involves one host being active, handling all monitoring and control tasks, with the second host running in a minimally functional, passive configuration. Data from the active host is constantly copied to the passive host to enable a rapid switchover as needed. This paper describes details of the implementation and practical experience of redundancy in the CMS DCS.

WEPGF019	Database Applications Development of the TPS Control System	EPICS, database, controls, interface	732
	Y.-S. Cheng, Y.-T. Chang, J. Chen, P.C. Chiu, K.T. Hsu, C. H. Huang, C.Y. Liao NSRRC, Hsinchu, Taiwan
	The control system had been established for the new 3 GeV synchrotron light source (Taiwan Photon Source, TPS) which was successful to commission at December 2014. Various control system platforms with the EPICS framework had been implemented and commissioned. The relational database (RDB) has been set up for some of the TPS control system applications used. The EPICS data archive systems are necessary to be built to record various machine parameters and status information into the RDB for long time logging. The specific applications have been developed to analyze the archived data which retrieved from the RDB. One EPICS alarm system is necessary to be set up to monitor sub-system status and record detail information into the RDB if the problem happened. Some Web-based applications with RDB have been gradually created to show the TPS machine status related information. The efforts are described at this paper.

WEPGF028	A Self-Configurable Server for Controlling Devices Over the Simple Network Management Protocol	controls, network, operation, monitoring	753
	V. Rybnikov, V. Petrosyan DESY, Hamburg, Germany
	The Simple Network Management Protocol (SNMP) is an open-source protocol that allows many manufacturers to utilize it for controlling and monitoring their hardware. More and more SNMP-manageable devices show up on the market that can be used by control systems for accelerators. Some SNMP devices are being used at the free-electron laser (FLASH) at DESY and planned to be used at the European X-ray Free Electron Laser (XFEL) in Hamburg, Germany. To provide an easy and uniform way of controlling SNMP devices a server has been developed. The server configuration, with respect to device parameters to control, is done during its start-up and driven by the manufacturer Management Information Base (MIB) files provided with SNMP devices. This paper gives some details of the server design, its implementation and examples of use.

WEPGF052	Development of the J-PARC Time-Series Data Archiver using a Distributed Database System, II	distributed, database, EPICS, hardware	818
	N. Kikuzawa, A. Yoshii JAEA/J-PARC, Tokai-Mura, Naka-Gun, Ibaraki-Ken, Japan H. Ikeda, Y. Kato JAEA, Ibaraki-ken, Japan
	The linac and the RCS in J-PARC (Japan Proton Accelerator Research Complex) have over 64000 EPICS records, providing enormous data to control much equipment. The data has been collected into PostgreSQL, while we are planning to replace it with HBase and Hadoop, a well-known distributed database and a distributed file system that HBase depends on. In the previous conference it was reported that we had constructed an archive system with a new version of HBase and Hadoop that cover a single point of failure, although we realized there were some issues to make progress into a practical phase. In order to revise the system with resolving the issues, we have been reconstructing the system with replacing master nodes with reinforced hardware machines, creating a kickstart file and scripts to automatically set up a node, introducing a monitoring tool to early detect flaws without fail, etc. In this paper these methods are reported, and the performance tests for the new system with accordingly fixing some parameters in HBase and Hadoop, are also examined and reported.

WEPGF080	Encoder Interface for NSLS-II Beam Line Motion Scanning Applications	interface, controls, FPGA, hardware	881
	R.A. Kadyrov, J.H. De Long, K. Ha, S. So, E. Stavitski BNL, Upton, Long Island, New York, USA
	The variety of motion control applications on existing and future NSLS-II beam lines demand custom control electronics developed to meet specific needs and ease integration to existing systems. Thus an encoder interface was designed for a number of detection techniques that require fly-scan applications. This design fits in a 2U chassis and can handle up to 4 incremental quadrature encoders with a digital RS-422A interface and output frequencies up to 10 MHz. The logic, based on Xilinx Virtex-6 FPGA, processes signals from an encoder, associates it with accelerator timestamp and sends the data to a server using TCP/IP stack, with the server side running an EPICS IOC. Several filtering and compression techniques are also applied. The device then re-translates the interface signals for the motion controller, allowing the device to be installed between encoder and motion controller with no interference to the system. The hardware leverages the NSLS-II BPM Digital Front End (DFE) board with Virtex-6 FPGA and periphery. The design harmoniously complements the family of NSLS-II equipment sharing same mechanical and electrical platform.

WEPGF100	DRAMA 2 - An Evolutionary Leap for the DRAMA Environment for Instrumentation Software Development	interface, software, GUI, controls	934
	T.J. Farrell, K. Shortridge AAO, North Ryde, Australia
	The DRAMA Environment provides an API for distributed instrument software development. It originated at the Anglo-Australian Observatory (now Australian Astronomical Observatory) in the early 1990s, in response to the need for a software environment for large distributed and heterogeneous systems, with some components requiring real-time performance. It was first used for the AAO's 2dF fibre positioner project for the Anglo-Australian Telescope. 2dF is still in use today, but has changed dramatically over time. DRAMA is used for other AAO systems and is or has been used at various other observatories looking for a similar solution. Whilst DRAMA has evolved and many features were added, there had been no big changes. It was still a largely C language based system, with some C++ wrappers. It did not provide good support for threading or exceptions. Ideas for proper thread support within DRAMA have been in development for some years, but C++11 has provided many features which allow a high quality implementation. The opportunity provided by C++11 has been taken to make significant changes to the DRAMA API, producing a modern and more reliable interface to DRAMA, known as DRAMA2.

WEPGF142	Advanced Matlab GUI Development with the DataGUI Library	GUI, software, interface, controls	1040
	S.M. Meykopff DESY, Hamburg, Germany
	On the DESY campus Matlab is a widely used tool for creating complex user interfaces. Although the on-board GUI tools are easy to use and provide quick results, the generated low-level code lacks uniformity and advanced features like automatic verification and conversion of input and output data. These limitations are overcome by the newly developed DataGUI library. The library is based on the model-view-controller software pattern and supports enhanced data handling, undocumented Matlab GUI elements, and configurable resizing of the user interface. An outlook on features of the upcoming release is also presented.

THHD3O05	Standards-Based Open-Source PLC Diagnostics Monitoring	PLC, monitoring, diagnostics, controls	1151
	B. Copy, H. Milcent, M.Z. Zimny CERN, Geneva, Switzerland
	PLCs are widely used to control and monitor industrial processes at CERN. Since these PLCs fulfill critical functions, they must be placed under permanent monitoring. However, due to their proprietary architecture, it is difficult to both monitor the status of these PLCs using vendor-provided software packages and integrate the resulting data with the CERN accelerator infrastructure, which itself relies on CERN-specific protocols. This paper describes the architecture of a stand-alone "PLC diagnostics monitoring" Linux daemon which provides live diagnostics information through standard means and protocols (file logging, CERN protocols, Java Monitoring Extensions). This information is currently consumed by the supervision software which is used by the standby service to monitor the status of critical industrial applications in the LHC and by the monitoring console used by the LHC operators. Both applications are intensively used to monitor and diagnose critical PLC hardware running all over CERN.

THHD3O06	Overview of the Monitoring Data Archive used on MeerKAT	database, interface, monitoring, GUI	1155
	M.J. Slabber SKA South Africa, National Research Foundation of South Africa, Cape Town, South Africa
	Funding: SKA South Africa National Research Foundation of South Africa Department of Science and Technology. MeerKAT, the 64-receptor radio telescope being built in the Karoo, South Africa, by Square Kilometre Array South Africa (SKA SA), comprises a large number of components. All components are interfaced to the Control and Monitoring (CAM) system via the Karoo Array Telescope Communication Protocol (KATCP). KATCP is used extensively for internal communications between CAM components and other subsystems. A KATCP interface exposes requests and sensors. Sampling strategies are set on sensors, ranging from several updates per second to infrequent updates. The sensor samples are of multiple types, from small integers to text fields. As the various components react to user input and sensor samples, the samples with timestamps need to be permanently stored and made available for scientists, engineers and operators to query and analyse. This paper present how the storage infrastructure (dubbed Katstore) manages the volume, velocity and variety of this data. Katstore is comprised of several stages of data collection and transportation. The stages move the data from monitoring nodes to storage node to permanent storage to offsite storage. Additional information (e.g. type, description, units) about each sensor is stored with the samples.

The control system had been established for the new 3 GeV synchrotron light source (Taiwan Photon Source, TPS) which was successful to commission at December 2014. Various control system platforms with the EPICS framework had been implemented and commissioned. The relational database (RDB) has been set up for some of the TPS control system applications used. The EPICS data archive systems are necessary to be built to record various machine parameters and status information into the RDB for long time logging. The specific applications have been developed to analyze the archived data which retrieved from the RDB. One EPICS alarm system is necessary to be set up to monitor sub-system status and record detail information into the RDB if the problem happened. Some Web-based applications with RDB have been gradually created to show the TPS machine status related information. The efforts are described at this paper.

The Simple Network Management Protocol (SNMP) is an open-source protocol that allows many manufacturers to utilize it for controlling and monitoring their hardware. More and more SNMP-manageable devices show up on the market that can be used by control systems for accelerators. Some SNMP devices are being used at the free-electron laser (FLASH) at DESY and planned to be used at the European X-ray Free Electron Laser (XFEL) in Hamburg, Germany. To provide an easy and uniform way of controlling SNMP devices a server has been developed. The server configuration, with respect to device parameters to control, is done during its start-up and driven by the manufacturer Management Information Base (MIB) files provided with SNMP devices. This paper gives some details of the server design, its implementation and examples of use.

The linac and the RCS in J-PARC (Japan Proton Accelerator Research Complex) have over 64000 EPICS records, providing enormous data to control much equipment. The data has been collected into PostgreSQL, while we are planning to replace it with HBase and Hadoop, a well-known distributed database and a distributed file system that HBase depends on. In the previous conference it was reported that we had constructed an archive system with a new version of HBase and Hadoop that cover a single point of failure, although we realized there were some issues to make progress into a practical phase. In order to revise the system with resolving the issues, we have been reconstructing the system with replacing master nodes with reinforced hardware machines, creating a kickstart file and scripts to automatically set up a node, introducing a monitoring tool to early detect flaws without fail, etc. In this paper these methods are reported, and the performance tests for the new system with accordingly fixing some parameters in HBase and Hadoop, are also examined and reported.

The variety of motion control applications on existing and future NSLS-II beam lines demand custom control electronics developed to meet specific needs and ease integration to existing systems. Thus an encoder interface was designed for a number of detection techniques that require fly-scan applications. This design fits in a 2U chassis and can handle up to 4 incremental quadrature encoders with a digital RS-422A interface and output frequencies up to 10 MHz. The logic, based on Xilinx Virtex-6 FPGA, processes signals from an encoder, associates it with accelerator timestamp and sends the data to a server using TCP/IP stack, with the server side running an EPICS IOC. Several filtering and compression techniques are also applied. The device then re-translates the interface signals for the motion controller, allowing the device to be installed between encoder and motion controller with no interference to the system. The hardware leverages the NSLS-II BPM Digital Front End (DFE) board with Virtex-6 FPGA and periphery. The design harmoniously complements the family of NSLS-II equipment sharing same mechanical and electrical platform.

DRAMA 2 - An Evolutionary Leap for the DRAMA Environment for Instrumentation Software Development

The DRAMA Environment provides an API for distributed instrument software development. It originated at the Anglo-Australian Observatory (now Australian Astronomical Observatory) in the early 1990s, in response to the need for a software environment for large distributed and heterogeneous systems, with some components requiring real-time performance. It was first used for the AAO's 2dF fibre positioner project for the Anglo-Australian Telescope. 2dF is still in use today, but has changed dramatically over time. DRAMA is used for other AAO systems and is or has been used at various other observatories looking for a similar solution. Whilst DRAMA has evolved and many features were added, there had been no big changes. It was still a largely C language based system, with some C++ wrappers. It did not provide good support for threading or exceptions. Ideas for proper thread support within DRAMA have been in development for some years, but C++11 has provided many features which allow a high quality implementation. The opportunity provided by C++11 has been taken to make significant changes to the DRAMA API, producing a modern and more reliable interface to DRAMA, known as DRAMA2.

DESY, Hamburg, Germany

On the DESY campus Matlab is a widely used tool for creating complex user interfaces. Although the on-board GUI tools are easy to use and provide quick results, the generated low-level code lacks uniformity and advanced features like automatic verification and conversion of input and output data. These limitations are overcome by the newly developed DataGUI library. The library is based on the model-view-controller software pattern and supports enhanced data handling, undocumented Matlab GUI elements, and configurable resizing of the user interface. An outlook on features of the upcoming release is also presented.

PLCs are widely used to control and monitor industrial processes at CERN. Since these PLCs fulfill critical functions, they must be placed under permanent monitoring. However, due to their proprietary architecture, it is difficult to both monitor the status of these PLCs using vendor-provided software packages and integrate the resulting data with the CERN accelerator infrastructure, which itself relies on CERN-specific protocols. This paper describes the architecture of a stand-alone "PLC diagnostics monitoring" Linux daemon which provides live diagnostics information through standard means and protocols (file logging, CERN protocols, Java Monitoring Extensions). This information is currently consumed by the supervision software which is used by the standby service to monitor the status of critical industrial applications in the LHC and by the monitoring console used by the LHC operators. Both applications are intensively used to monitor and diagnose critical PLC hardware running all over CERN.

MeerKAT, the 64-receptor radio telescope being built in the Karoo, South Africa, by Square Kilometre Array South Africa (SKA SA), comprises a large number of components. All components are interfaced to the Control and Monitoring (CAM) system via the Karoo Array Telescope Communication Protocol (KATCP). KATCP is used extensively for internal communications between CAM components and other subsystems. A KATCP interface exposes requests and sensors. Sampling strategies are set on sensors, ranging from several updates per second to infrequent updates. The sensor samples are of multiple types, from small integers to text fields. As the various components react to user input and sensor samples, the samples with timestamps need to be permanently stored and made available for scientists, engineers and operators to query and analyse. This paper present how the storage infrastructure (dubbed Katstore) manages the volume, velocity and variety of this data. Katstore is comprised of several stages of data collection and transportation. The stages move the data from monitoring nodes to storage node to permanent storage to offsite storage. Additional information (e.g. type, description, units) about each sensor is stored with the samples.
