ITER and CODAC Core System - Status and Road Map
ITER is a large international project building a fusion facility in the South of France. Most contributions are in-kind - integration of more than 200 plant systems will be the main challenge when building the control system. To support controls development of plant systems, ITER created CODAC Core System (CCS), a Linux Distribution based on RedHat Enterprise Linux, EPICS and ITER specific tools.

LCLS-II Status
The new LCLS-II facility at the SLAC National Accelerator Laboratory is a significant addition to the LCLS-I FEL, designed to dramatically decrease data acquisition time by providing high repetition rate over a broad energy range. The new design consisting of a CW superconducting linac with bunch repetition rates of up to one MHz and beam power of several hundred kilowatts requires major enhancements to the LCLS-I controls system. LCLS-II will retain the system architecture based on EPICS while implementing additional technologies to meet the new requirements. This includes new designs for SC LLRF, timing system to allow MHz operation, data acquisition electronics for the beam position monitors and other beam diagnostic systems, and a new beam-based feedback facility. The high beam rate and power also necessitate faster beam abort mechanisms, requiring enhanced machine and personnel protection systems as well as a new radiation containment system. This talk will present an overview of the LCLS-II controls and discuss the design status of the critical systems including the development of a general purpose electronic system to serve as a common platform for several applications.

Status of RAON control system
The Rare Isotope Science Project (RISP) at the Institute for Basic Science (IBS) constructs the rare isotope accelerator facility in South Korea. Since the facility uses stable ion beams and rare isotope beams dependently, independently, or both, possible operation modes and its combination could be a complex of different accelerator sub-systems. Therefore it will be a challenge to build an integrated control systems for the rare isotope accelerator named as RAON. In this report, we will present current status of the overall RAON control systems based on EPICS.

Overview and Status of the SwissFEL Project at PSI
Recently, the installation of the components for the free electron laser SwissFEL has started at the Paul Scherrer Institute (PSI). In February 2016, beginning of the injector commissioning is planned and first lasing is foreseen a year later. New hardware, like VME64x­boards (IFC 1210, an P2020 based intelligent FPGA controller from IOxOS) and ­crates (Trenew), timing system (from MRF with advanced features), motion controllers (Power PMAC from Delta Tau, and MDrive from Schneider), among others, as well as modern field buses, pose great challenges to the controls team. The close interaction of machine­ and experiment­components require advanced software concepts for data­acquisition, ­distribution, and ­archiving. An overview of the project will be presented and the different HW and SW solutions based on the experience gained from preliminary implementations at other facilities of PSI will be explained. First results of the HW commissioning at the SwissFEL will be reported.

From VME/RTEMS to Industrial PC/LinuxRT: A Migration Story
Until recently VME RTEMS-based IOCs have been the platform of choice for control systems at SLAC. Cost and hardware availability make industrial PCs running Linux an attractive option for EPICS based IOCs. The CONFIG_PREEMPT_RT patch has been used to significantly improve the real-time performance of Linux. We will discuss real-time performance issues and migration experience for LinuxRT based EPICS IOCs.

The Linac Coherent Light Source is a free electron laser (FEL) facility operating at the SLAC National Accelerator Laboratory (SLAC). The controls for low current powered magnets use a multi-channel power supply controller system (MCOR) to meet the requirements for LCLS. It has a modular architecture that consists of a rack mounted crate, with 16 removable power modules and 1 crate controller. A bulk power supply provides the main DC power for one or more crates. The I/O signals are read by the control system from VME, with an MVME 6100 Power PC CPU, 16-bit, 16-channel ADC and DAC IPAC modules, and a PMC-Event Receiver (EVR) to provide timing for fast feedback over a dedicated network. The MCOR system provides long term stability of 1000ppm over diurnal range of +/-15 degrees C, and can operate up to 120Hz, to meet fast feedback requirements. The upgrade to this system is a SLAC designed slot-0 controller with 2 Gigabit Ethernet ports, USB and serial port, 4 8-channel ADC, 4 8-channel DAC, Digital input and output channels, removable COMx CPU, Xilinx FPGA, timing supporting multi-mode or single mode, and interrupts. A prototype installation has been operating in LCLS Linac for 6 months and will be used for LCLS-II. This paper presents the controls upgrade motivation and commissioning results.

softGlue: user programmable digital electronics
softGlue is an EPICS module that supports the Acromag IP-EP20x IndustryPack module (FPGA-based digital I/O). It enables users and application developers to construct small, simple, digital electronic circuits, and to connect those circuits to field wiring, all by writing to EPICS PV's. Because the circuits and field connections are defined entirely by EPICS PV's, they can be autosaved and restored, saved as text files (for example, as BURT snapshot files), emailed from one user to another, etc. softGlue also provides simple and safe (throttled) user control over how hardware interrupts are generated by field I/O signals, and how they are dispatched to cause EPICS record processing.

EPICS integration of Raspberry Pi Monitoring System for simple applications and user trainings
The Raspberry Pi is a very small size computer and it can connect to various sensors via GPIO ports. So It can be used not only IOC but also control device itself. In this report we'd like to present how to use and integrate into epics system. The first one is environment monitoring system which is consist of temperature sensor and serviced via web browser. The next one is a raspberry pi training kit for education. Because of low cost, The raspberry pi is very good device for epics start user.

RAON EPICS integration of SNMP and its realization at early stage
The Rare Isotope Science Project (RISP) at the Institute for Basic Science (IBS) constructs the rare isotope accelerator facility in South Korea. The accelerator control system uses various Ethernet-based devices and equipment, and most Ethernet-based devices support Simple Network Management Protocol (SNMP). Therefore, SNMP is useful to build a unified Network-based control system. In this presentation, we will present our trials and the status for EPICS integration of SNMP.

Deploying CS-Studio at DLS
About one year ago, it was decided to evaluate CS-Studio as a replacement for EDM at Diamond. Since then, much work has gone into making CS-Studio and BOY a viable replacement for the many existing deployed EDM screens without disrupting existing ways of working. This talk describes the problems and solutions found, including the new work on OPI Shells, and shows how CS-Studio may finally be deployed for both machine and beamline operation at DLS.

Monitoring Dynamic IOC Installations Using the alive Record
The alive record is part of a system used at the Advanced Photon Source for monitoring the IOCs on the experimental floor. These IOCs are spread across many subnets, are maintained by multiple people, run different versions of software, and some travel between sectors. For the beamline support groups, monitoring and maintaining these IOCs can be time-consuming as one is not sure of the current or most recent state for an IOC. The alive record allows an IOC to ping a central server across subnets, as well as provide upon demand from the server certain environment variables set at boot-time. This provides at the server an active list of IOC operational statuses, as well as configuration information about each IOC with information specific to an OS. At the APS, over 100 IOCs on the floor are in this sytem, with such systems as traditional VME-based ones as well as mobile detector computers.

Status Monitoring of the EPICS Control System at the Canadian Light Source
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.

Driver/Device Support sis3316/ip
Driver/Device Support sis3316/ip We have developed a driver support for the digitizer Struck sis3316 which uses the Gbit-Ethernet interface on that card. To communicate with the digitizer we are using a C-library supported by Struck. The communication is based on the UDP protocol. Within the library unfortunately error cases are not threaded properly. We had to customize the library in some places that, e. g. Packet losses are properly handled. We are still in the process to integrate the time stamp of the card into the created EPICS record. I hope that it is possible to compare our implementation with the standard vmebus driver up to our meeting. I just ordered a MVME6100 to continue with the comparative tests.

Accessing NI Network Shared Variables from EPICS IOCs
Network Variables are a convenient method for sharing information between National Instruments (NI) software and hardware. We have developed a configurable EPICS IOC for accessing information from such sources and exporting them as process variables, the intention being to use the shared variables as a clean interface between our EPICS control system and some specific third party provided equipment. The IOC software uses the LabWindows/CVI Network Variable Library and so can be run on Windows and several flavours of Linux.

EPICS Independent Test Suite for PCI-based controls devices using PythonQT
In this paper we present the generic solution for testing PCI-based hardware devices on Linux. For simple device manipulation, EPICS provides additional layer of complexity, which is usually not desired by the people who are just interested that device works on its own. The paper presents four software modules that were developed to ease the testing of such hardware devices remotely, without the usage of EPICS. The complete solution provides a server that exposes device data on the network, client Python API to modify the data remotely, and PythonQt GUIs that enable the user to change the data easily as well as run automated Python tests and generate their reports. Implemented software package was successfully used for testing EMCOR controller at SLAC National Accelerator Laboratory. Since it has been made with reusability in mind, it can be used for any other PCI-based hardware device without additional effort.

Development Plan for Reliable Card-size IOC
Recent card-size PCs, such as Raspberry Pi or BBB (Beagle bone black), have enough performance to use as EPICS IOCs. In ERL in KEK-Tsukuba, a few pieces of BBB IOCs with serial lines were developed to monitor radiation-monitoring instruments [1]. However, due to lack of long-term reliability and hardness, mass introduction to accelerator controls is not realistic. We have started study to develop a customized card-size PC. It will: 1) use long-term guaranteed parts, 2) has simple IOs (1 LAN, 2 serials, 8bit io), 3) be used with a hard metal-chassis, and 4) be not low-cost but ... We hope to develop a prototype by the end of FY2015. After 2016, it will be used for newly introduced devices. In addition, part of legacy VME-bus IOCs in J-PARC MR will be replaced by them.

Dynamic logging configuration in CS-Studio
Additional information from the logger in CS-Studio would make it easier to identify and resolve issues. It is not possible to have the logger's default configuration set to a very fine level due to the volume of messages it would produce. The logging configuration tool provides a user interface which lists all the JVM loggers and allows users to dynamically change their logging levels. This allows acquiring detailed logs for only the potentially problematic pieces.

areaDetector: What’s New? M. L. Rivers, Center for Advanced Radiation Sources (CARS), The University of Chicago, Chicago, IL 60637 This talk will focus on enhancements to the areaDetector package since it was last presented at the 2014 collaboration meeting at Saclay. These include: - New driver for cameras from QImaging. - New driver for Dexela flat-panel CMOS detectors from Perkin Elmer. - New driver for detectors from Princeton Instruments using their PICam library. - New driver for the Merlin detector from Quantum detectors. - Added the modules ffmegViewer, ffmegServer, aravisGogE, and firewireDCAM to the github repository. These modules were written at Diamond Light Source and were previously hosted there. - NDPluginROIStat: New plugin that supports multiple regions-of-interest with simple statistics on each. It is more efficient and convenient than the existing NDPluginROI and NDPluginStats when many regions of interest with simple statistics are needed. - NDPluginCircularBuff: New plugin that implements a circular buffer. NDArrays are stored in the buffer until a trigger is received. When a trigger is received it outputs a configurable number of pre-trigger and post-trigger NDArrays. The trigger is based on NDArray attributes using a user-defined calculation. - NDPluginAttribute: New plugin that exports attributes of NDArrays as EPICS PVs. Both scalar (ai records) and time-series arrays (waveform records) are exported. - iocs/simDetectorNoIOC: New application that demonstrates how to instantiate a simDetector driver and a number of plugins in a standalone C++ application, without running an EPICS IOC. Applications only need the libCom library from EPICS base and the asyn library. The talk will also discuss future plans for the areaDetector package.

Time source callback and attribute plugin for areaDetector
Timestamp tagging to data and aligning data to individual beam pulse are important part of data acquisition system for pulse machine. We have utilized Beam Synchronous Acquisition (BSA) for LCLS, FACET and other accelerator facilities in SLAC. BSA provides a common interface for the timestamp tagging and aligning data to beam pulse. Unfortunately, we could not get benefit from the BSA for camera image data due to the image is an array data and it should be stored as image file format. BSA only supports scalar type epics PV. Our timing system in SLAC has 360Hz granularity. Most of image processing and acquiring cycles are non-deterministic in time domain and spend longer time than the 360Hz timestamp update period. These bring difficulty of timestamp tagging for image data. We have discussed with Mark Rivers, author for the areaDetector module, about time source callback to implement the driver level timestamp tagging with user defined function. The driver level timestamp tagging gives more deterministic and real-time behavior. The timestamp is stored as a part of meta-data of the image and can be utilized by downstream plugins such as file plugin which saves the timestamp into image file format. We also discussed to extend attribute plugin to post out the timestamp related data to epics PVs. He reflected our requirements for the time source callback in the latest areaDetector module and the attribute plugin also. We are going to describe the details about the time source callback and attribute plugin.

Fast Data Storage system for PAL-XFEL
We have developed a fast data storage and archiving system for the PAL-XFEL project. The system monitors around 5000 EPICS PVs, updated at 60Hz, most of which are scalars. The system keeps, at a minimum, 5 minutes of short-term history available for retrieval at any time. On the other hand, the system allows for long-term preservation of data from specific time intervals. This includes preservation of both past buffered data as well as future data. For example, the system can be configured to preserve the last 5 minutes and the next 2 minutes of data in the event of an interlock, or upon manual request by a user. As the basic interface, the system accepts HTTP requests to preserve a specific time frame of data. There is also an option to issue such data preservation requests based on updates of PVs. The system is based on the EPICS Archiver Appliance software with modifications that implement the data preservation logic, along with various improvements related to the data storage logic and general performance.

Software Architecture of a Remotely Monitored Dosimetry System
A study of absorbed dose in undulator magnets at SLAC's Linac Coherent Light Source (LCLS) was performed using RADFET dosimeters. An extrapolation of the dose rate observed with the present LCLS, at 120 Hz, to the 1-MHz rate planned for LCLS II suggests the new system's permanent magnets could have an unacceptably short useable lifespan. In order to study factors affecting integrated dose rate in real time, a networked system was designed to monitor up to 168 RADFETs, with the accumulate/read cycle implemented in Keithley's Test Script Builder (TSB). TSB is an extension of the Lua language, used for local control and serial communications. Thus we had the opportunity to design and implement both a streamdevice based EPICS IOC and the device it controls. Design of both sides of the system and the overall system will be presented. Functionality is divided by where it can best be performed, with a minimal and specialized protocol to bridge the parts.

Ophyd: Software for Data Collection, Management, and Analysis
Ophyd is a Python-based framework for experiment control under development at Brookhaven National Lab and deployed for use on NSLS-II beamlines. The software supports device control, data collection and distribution, reciprocal space operations, integration with electronic logging, and more. Ophyd is coupled with searchable back-end storage and retrieval components, which together form an end-to-end data management architecture for the NSLS-II. An overview of Ophyd’s architecture and its accompanying data management infrastructure will be discussed.

The beamlines at NSLS-II are among the highest instrumented, and controlled of any worldwide. Each beamline can produce unstructured data sets in various formats. This data should be made available for data analysis and processing for beamline scientists and users. Various data flow systems are in place in numerous synchrotrons, however these are very domain specific and cannot handle such unstructured data. We have developed a data flow service, metadatastore, that manages experimental data in NSLS-II beamlines. This service enables data analysis and visualization clients to access this service either directly or via databroker api in a consistent and partition tolerant fashion, providing a reliable and easy to use interface to our state-of-the-art beamlines.

NSLS-II Data Management
Each NSLS-II beamline can generate 72,000 data sets per day, over 2 M data sets in one year. The large amount of data files generated by our beamlines poses a massive file management challenge. In response to this challenge, we have developed filestore, as means to provide users with an interface to stored data. By leveraging features of Python and MongoDB, filestore can store information regarding the location of a file, access and open the file, retrieve a given piece of data in that file, and provide users with a token, a unique identifier allowing them to retrieve each piece of data. Filestore does not interfere with the file source or the storage method and supports any file format, making data within files available for NSLS-II data analysis environment.

Past, present, and future of EPICS Qt
A serious drawback that exists today is the lack of comprehensive frameworks on which to develop high level applications on top of EPICS. The lack of modern alternatives to antiquated codes has stalled progress in control systems development and presents impending difficulties for both private and public users to maintain EPICS. In the past few years, controls engineers from different accelerator facilities have proposed to extend code-reuse to higher level applications by advocating a modern framework, Qt. The goal of this presentation is to communicate the recent progress of the EPICS Qt collaboration. The EPICS Qt framework is Python, C/C++, and Qt environment. Unlike MEDM and EDM, EPICS Qt is modern, well-documented, and backed by a healthy community. Like Tk, EPICS Qt is free and open source. EPICS Qt offers the potential of seamless integration of MATLAB-like software. Like LabVIEW, EPICS Qt allows for fast prototyping. EPICS Qt's many-language bindings offer existing facilities a smooth transition to a modern high-level framework. EPICS Qt will be viable alternative to CSS through the involvement of the EPICS community and the development of open source tools, ultimately providing a strong foundation for many types of control systems across DOE labs as well as private industries that use DOE accelerator technology.

Moving towards Continuous Delivery
The complexity of the FRIB control system requires high code quality while, particularly during the commissioning phase, short turn-around times are desirable. We will present the status of our efforts moving towards automated software builds, deploying and managing FRIB's controls infrastructure. The tools used in this process include a revision control system (Git), software packaging (for Debian), continuous integration services (Jenkins), configuration management (Puppet) and automatically installed virtual machines for development (Vagrant).

caputRecorder: a "macro" recorder for EPICS
caputRecorder supports the recording and playback of sequences of caputs. It records each caput as a python command, and a sequence of caputs as a python function (users call this a "macro"). caputRecorder can also serve as a simple user interface for delivering canned python functions to end users. caputRecorder communicates with users via an EPICS database, so it allows any EPICS record or channel-access client to record and run python functions, and to wait for them to complete. See http://www.aps.anl.gov/bcda/synApps/caputRecorder/caputRecorder.html

Paired Redundant IOCs with Redundant Hardware
Last year we installed a dual redundant master timing system at LANSCE. A fiber-optic fanout concentrator module acts as a switch to select which timing generator is used to control the accelerator. Each generator consists of two IOCs, which must fail over as a pair. We modified the redundant IOC software from DESY to be able to synchronize some PVs but not others, and allow both IOCs to control hardware simultaneously. If the master stops generating timing signals, our software on the slave first commands the switch and then tells the IOCs to follow suit. I will discuss the modifications we made, and our experience in operating these IOCs.

DISCS Status
Distributed Information Services for Control Systems (DISCS) is a framework for building high-level applications for commissioning, operation, and maintenance of an experimental physics facility. It provides programmatic as well as graphical interfaces to its data and services. It is comprised of a set of cooperating services and applications, and manages data such as naming, machine configuration, lattice, measurements, alignment, cables, machine state, inventory, operations, calibration, and design parameters. The services/applications include Logbook, Traveler, Unit Conversion, Online Model, and Save-Restore. Each component of the system has a database, an API, and a set of applications. The services are accessed through RESTful and EPICS V4 interfaces. We present the current status of DISCS.

Developing a user interface for experiment control at the ISIS neutron and muon spallation source
For over ten years the beamline instruments at the ISIS neutron and muon spallation source have been operating successfully using a LabVIEW-based control system. However, a range of new instruments are being built, offering the potential to implement very complex experiments. For this reason, the long-term suitability of the control system was reviewed. Based on this review, it was decided that switching to an EPICS-based system would offer many advantages in terms of flexibility, code reuse and collaboration. Over the last two years, the ISIS Computing Group has been developing this new EPICS-based control system whilst maintaining the existing system. The new system, which is still under active development, is currently being used to commission a new instrument on ISIS’s second target station. This presentation will describe: • The strengths and weaknesses of the existing control system and how this has fed into the design of the new EPICS-based system • The architecture of the new system • The development of a new graphical user interface • The current state of the control system and thoughts about the progress so far

WebPODS: web gateway and HTML/CSS widgets
There is an increasing interest to access data coming out of the control system through web technology. Use cases includes the integration with other web tools, applications on tablets/devices, office network live reports/status and off campus access for monitoring beamlines. WebPODS aims to provide a specification based on HTTP/WebSockets/JSON to access the data, a server implementation to act as a gateway, a javascript client library, a set of pure HTML/CSS widgets to display such data and a Java client library. The server utilizes DIIRT as the connection layer, the same engine used in CS-Studio, and therefore makes already available a broad set of functionality (e.g. support for different protocols, formulas, …). As the project has completed its first official release, we go through its status, its functionality and its future.
