  The machine control system of the synchrotron radiation source ANKA at KIT (Karlsruhe Institute of Technology) is migrating from dedicated I/O microcontroller boards that utilise the LonWorks field bus and are visualised with the ACS Corba based control system to Ethernet TCP/IP devices with an EPICS server layer and visualisation by Control System Studio (CSS). This migration is driven by the need to replace ageing hardware, and in order to move away from the outdated microcontroller's embedded LonWorks bus. Approximately 500 physical devices, such as power supplies, vacuum pumps etc, will need to be replaced (or have their I/O hardware changed) and be integrated to the new EPICS/CSS control system. In this paper we report on the technology choices and discuss justifications of those choices, the progress of migration, and how such a task can be achieved in a transparent way with a fully user operational machine. We also report on the benefits reaped from using EPICS, CSS and BEAST alarming.

  IEC 61850, as part of the International Electro-technical Commission's Technical Committee 57, defines an international and standardized methodology to design electric power automation substations. It specifies a common way of communicating and integrating heterogeneous systems based on multivendor intelligent electronic devices (IEDs). They are connected to Ethernet network and according to IEC 61850 their abstract data models have been mapped to specific communication protocols: MMS, GOOSE, SV and possibly in the future Web Services. All of them can run over TCP/IP networks, so they can be easily integrated with Enterprise Resource Planning networks; while this integration provides economical and functional benefits for the companies, on the other hand it exposes the industrial infrastructure to the external existing cyber-attacks. Within the Openlab collaboration between CERN and Siemens, a test-bench has been developed specifically to evaluate the robustness of industrial equipment (TRoIE). This paper describes the design and the implementation of the testing framework focusing on the IEC 61850 previously mentioned protocols implementations.

  We describe a combined ultrasonic instrument for continuous gas flow measurement and simultaneous real-time binary gas mixture analysis. The analysis algorithm compares real time measurements with a stored data base of sound velocity vs. gas composition. The instrument was developed for the ATLAS silicon tracker evaporative cooling system where C3F8 refrigerant may be replaced by a blend with 25% C2F6, allowing a lower evaporation temperature as the LHC luminosity increases. The instrument has been developed in two geometries. A version with an axial sound path has demonstrated a 1 % Full Scale precision for flows up to 230 l/min. A resolution of 0.3% is seen in C3F8/C2F6 molar mixtures, and a sensitivity of better than 0.005% to traces of C3F8 in nitrogen, during a 1 year continuous study in a system with sequenced multi-stream sampling. A high flow version has demonstrated a resolution of 1.9 % Full Scale for flows up to 7500 l/min. The instrument can provide rapid feedback in control systems operating with refrigerants or binary gas mixtures in detector applications. Other uses include anesthesia, analysis of hydrocarbons and vapor mixtures for semiconductor manufacture.

  SPES (Selective Production of Exotic Species) is an ISOL type RIB facility of the LNL-INFN at Italy dedicated to the production of neutron-rich radioactive nuclei by uranium fission. At the LNL, for the last four years, an off-line laboratory has been developed in order to study the target front-end test bench. The instrumentation devices are controlled using EPICS. A new flexible, easy to adapt, low cost and open solution for this control system is being tested. It consists on EPICS IOCs developed at the LNL which are based on the low cost computer board Raspberry Pi with custom-made expansion boards. The operating system is a modify version of Debian Linux running EPICS soft IOCs that communicates with the expansion board using home-made drivers. The expansion boards consist on multi-channel 16bits ADCs and DACs, digital inputs and outputs and stepper motor drivers. The idea is to have a distributed control system using customized IOC for controlling the instrumentation devices on the system as well as to read the information from the detectors using the EPICS channel access as communication protocol. This solution will be very cost effective and easy to customize.

TUPPC096 Migration from WorldFIP to a Low-Cost Ethernet Fieldbus for Power Converter Control at CERN controls, interface, software, network 805

  Power converter control in the LHC uses embedded computers called Function Generator/Controllers (FGCs) which are connected to WorldFIP fieldbuses around the accelerator ring. The FGCs are integrated into the accelerator control system by x86 gateway front-end systems running Linux. With the LHC now operational, attention has turned to the renovation of older control systems as well as a new installation for Linac 4. A new generation of FGC is being deployed to meet the needs of these cycling accelerators. As WorldFIP is very limited in data rate and is unlikely to undergo further development, it was decided to base future installations upon an Ethernet fieldbus with standard switches and interface chipsets in both the FGCs and gateways. The FGC communications protocol that runs over WorldFIP in the LHC was adapted to work over raw Ethernet, with the aim to have a simple solution that will easily allow the same devices to operate with either type of interface. This paper describes the evolution of FGC communications from WorldFIP to dedicated Ethernet networks and presents the results of initial tests, diagnostic tools and how real-time power converter control is achieved.

  As defined by the CODAC Architecture of ITER, a Plant System Host (PSH) and one or more Slow Controllers (SIEMENS PLCs) are connected over a switched Industrial Ethernet (IE) network. An important part of Software Engineering of Slow Controllers is the standardization of communication between PSH and PLCs. Based on prototyping and performance evaluation, Open IE Communication over TCP was selected. It is implemented on PLCs to support the CODAC data model of ‘State’, ‘Configuration’ and ‘Simple Commands’. The implementation is packaged in Standard PLC Software Structure(SPSS) as a part of CODAC Core System release. SPSS can be easily configured by the SDD Tools of CODAC. However Open IE Communication is restricted to the PLC CPUs. This presents a challenge to implement redundant PLC architecture and use remote IO modules. Another version of SPSS is developed to support communication over Communication Processors(CP). The EPICS driver is also extended to support redundancy transparent to the CODAC applications. Issues of PLC communication standardization in the context of CODAC environment and future development of SPSS and EPICS driver are presented here.

  SuperKEKB is the upgrade of the KEKB asymmetric energy electron-positron collider, for the next generation B-factory experiment in Japan. It is designed to achieve a luminosity of 8x1035/cm2/s, 40 times higher than the world highest luminosity record at KEKB. For SuperKEKB, we upgrade the accelerator control network system, which connects all devices in the accelerator. To construct the higher performance network system, we install the network switches based on the 10 gigabit Ethernet (10GbE) for the wider bandwidth data transfer. Additional optical fibers, for the reliable and redundant network and for the robust accelerator control timing system, are also installed. For the KEKB beamline construction and accelerator components maintenance, we install the new wireless network system based on the Leaky Coaxial (LCX) cable antennas into the 3 km circumference beamline tunnel. We reconfigure the network design to enhance the reliability and security of the network. In this paper, the design and current status of the SuperKEKB accelerator control network system will be presented.

  ARM microcontrollers have high processing speed and low power consumption because they work efficiently with less memory by their own instruction set. Therefore, ARM microcontrollers are used not only in portable devices but also other commercial electronic devices. In recent years, free development environments and low-cost development kits are provided by many companies. The “mbed” provided by NXP is one of them. The “mbed” provides an environment where we can develop a product easily even if we are not familiar with electronics or microcontrollers. We can supply electric power and can transfer the program that we have developed by connecting to a PC via USB. We can use USB and LAN that, in general, require high level of expertise. The “mbed” has also a function as a HTTP server. By combining with JavaScript library, we can control multiple I/O ports at the same time through LAN. In the presentation, we will report the results that we applied the “mbed” to develop an RF signal switching system for a turn-by-turn beam position monitor (BPM) at a synchrotron light source, UVSOR-III.

  Two synchronization layers for timing systems in large experimental physics control systems are compared. White Rabbit (WR), which is an emerging standard, is compared against the well-established event based approach. Several typical timing system services have been implemented on an FPGA using WR to explore its concepts and architecture, which is fundamentally different from an event based. Both timing system synchronization layers were evaluated based on typical requirements of current accelerator projects and with regard to other parameters such as scalability. The proposed design methodology demonstrates how WR can be deployed in future accelerator projects.
