  An Infrastructure Monitoring System has been developed at Argonne National Laboratory’s Advanced Photon Source (APS) to provide immediate notification to the Controls Group on-call staff in the event of failure of critical controls hardware components or software processes. Approximately 6,000 critical controls components and processes have been identified, many of which can be readily monitored through EPICS records. Nagios , an open-source host, service, and network monitoring program, has been interfaced to EPICS Channel Access monitoring tools to provide historical tracking of controls infrastructure events, email, and pager notifications to on-call staff, and Internet-accessible status displays. Two methods have been evaluated for checking EPICS alarm status data: a modified version of Mauro Giacchini’s NAL plug-in for Nagios, and a Perl script using the Channel Access Perl library recently developed by Andrew Johnson. A Personal Device Assistant-viewable Web page is also generated independently of Nagios that provides customized links to the controls database IRMIS . Performance studies have validated the reliability of Nagios and the Perl Channel Access software.

  Publish/subscribe message passing is an extremely simple, flexible, and powerful interprocess communication paradigm. It is widely used in industry, but not nearly so in HENP, perhaps due to the cost of commercial implementations. cMsg, developed at Jefferson Lab in the US, contains a full-featured pub/sub interprocess communication package that is simple to install and use. It is very efficient, and implements both point-to-point and pub/sub communications, server redundancy, hot server failover, and a server discovery service. In addition, for developers cMsg provides a framework within which one can deploy multiple underlying communication packages that do not necessarily need to implement the full pub/sub paradigm. This allows for unification of all communication in a control system under a single API, shortens development time, and allows for simple upgrade or replacement of underlying communication packages and protocols.

MOW03 Integration of Renovated Networking Middleware into a Running Control System Environment controls, extraction, coupling, ion-source 37

    GSI, Darmstadt
  Currently the proprietary networking middleware in the GSI control system is replaced by a CORBA based re-design. Rebuilding all controls components is out of scope, so existing applications as well as device specific front-end software still have to be used. The renovated middle layer has to fit between the former applications device access interface and the front-end framework. Providing similar functionality as before was a major design aspect therefore. However, the new outline, targeting more flexibility and clearity, did not completely provide the established functionality from the beginning. Several extensions, had to be added which on the other hand lead to additional capabilities for future usage of the system.

TUY04 TINE Video System – A Modular, Well-defined, Component-based and Interoperable TV System Undergoing a Redesign controls, diagnostics, electron, laser 64
 
  • S. Weisse
    DESY Zeuthen, Zeuthen
  In recent years, the usage of TV systems and optical readout at accelerator facilities has constantly been increasing. At the same time, the pace of vendor upgrades of industrial vision hardware has hardly slackened. Because image readout hardware is required to meet special criteria in accelerator physics, vastly different hardware systems are frequently used side by side. Given such circumstances it is not surprising that the imaging software needs to be changed, adapted and updated on a semi-permanent basis. Current TV systems cannot cope very well with rapid software and hardware changes. To improve this, a redesign of the current TINE Video System*, initiated at PITZ, was undertaken. Efforts are focused on an abstract, modular grabbing interface, dedicated software components, a well-defined Video Transport Layer and use of standard file formats where possible. This paper will show current, planned and possible software architectures as well as hardware support and outlines perspectives for near and far future. Although the current implementation is integrated into TINE control system, it is modular enough so that integration into other control systems can be considered.

  One of the strengths of the TINE* control system is the ability to easily make ‘rich-client’ applications containing that programming and display logic which is designed to expedite and enhance the operator’s or physicist’s abilities to diagnose problems and correlate results. In particular there are a large number of ‘rich-client’, general purpose applications which offer extensive interactions with the TINE standard servers and subsystems. This includes the TINE archive system, alarm system, post-mortem system, and video system, as well as scope trace analysis, multi-channel analysis and general configuration management. Available now for many years, these diagnostic applications have recently been realized as pure java applications using ACOP** beans. All applications have been honed and refined based on extensive feedback from the application users. We offer here a description of these applications, some of the novel techniques used and focus on those ‘rich-client’ aspects which cannot be achieved by configuring ‘simple-clients’ based on displayer widgets.

TUP005 Overview of the Personnel Safety System at the Heidelberg Ion Therapy Facility controls, radiation, ion, ion-source 88
 
  • S. Scheloske, J. M. Mosthaf
    HIT, Heidelberg
  The HIT (Heidelberg Ion Beam Therapy) Centre is the first heavy ion therapy accelerator in Europe, which is operated by the university hospital of Heidelberg, Germany. In accordance with the german radiological protection ordinance, a personnel safety system (PSS) was installed during the comissioning of the accelerator. Main functions of the PSS are radiation protection, gate control, emergency stop handling, change of the state of the protection areas and safety interlocks. The PSS is a stand alone part of the accelerator control system and consists of several OPC servers and a special designed GUI for the control room. The installation of the PSS was started in June 2006 and finished in March 2008. This presentation will report on the concept and realization of the PSS.

  Beam-loss level monitoring is a powerful diagnostic tool concerning accelerator health. Particles leave the vacuum pipe for various reasons, such as intrabeam scattering (Touschek effect), residual gas molecules, closed orbit distortions or mechanical obstacles (aperture restrictions, installation errors). These can be identified by appropriate measurements. The steady-state beam loss level varies throughout the machine and has to be measured and documented for further reference. Besides general radiation safety purposes, changes (especially increases) occurring after machine upgrades are of special interest. When simple monitoring of average beam loss fluctuations is insufficient, problem diagnostics should be further enhanced by correlating beam loss monitor (BLM) detector readout with events in the machine. For best flexibility, pulses should only be counted at certain conditions and during well defined time slots synchronized with the current machine operation cycle. In cooperation with Cosylab, such an advanced BLM acquisition system was developed for the Electron Stretcher Accelerator ELSA (University of Bonn, Germany), allowing various optimized acquisition modes.

  The Free Electron Laser in Hamburg (FLASH) at DESY is a user facility. It produces laser light of short wavelengths from the extreme ultraviolet down to soft X-rays. To study, monitor and document the machine performance and parameters and also to collect the results of the experiment measurements a fast data acquisition (DAQ) system has been developed. A shared memory based buffer manager is the heart of the system. It arranges collected data as events for every linac short. All events can be read by different consumers simultaneously. Linac feedback and monitoring processes as well as experiment middle layer servers are typical clients of the buffer manager. Any client can also generate its own data and insert it into the same event or produce its own one. The paper will focus on the detailed implementation of the buffer manager and its main features. The experience and the achieved performance will be covered as well.

  The temperature conditions affect the circulating bunches parameters in colliders. So, the permanent temperature measurements are very important for the estimation of the beam energy during the experiments with colliding beams. The system is realized in order to measure precisely temperature in a lot of points (about 500) of the VEPP-4M facility: magnet yokes, coils, air in the tunnel and electrical power connections, RF cavities, water cooling, environment. The system provides the interlock functions. In the case of overheating in measuring points the system switch off the corresponding power supplies. The system is based on using of DS1631Z Accuracy Digital Thermometers and 32-channel home-developed controller. The controllers are connected to PC via serial interface. Temperature values are renewed automatically for the all channels in each controller in 0.75 second. The program running in PC reads the data from the all controllers and transfers the temperature data to PostgreSQL database every minute. The graphic interface provides browsing of the temperature diagrams for the selected thermometers for any period of time. All the programs run under Linux.

  The EMBL is located at the DESY site in Hamburg and operates 5 beamlines at the DORIS III storage ring. Currently the EMBL Hamburg is in charge to build three new beamlines at the new PETRA III high-brilliance synchrotron radiation source which will commence user operation in 2009. A new multilayer double-crystal monochromator has been developed in house. This has been a real application test for the software and hardware architecture of the new PETRAIII beamlines. An embedded-PC controls the electronic integrated in the EtherCAT real-time Ethernet bus. Inside this PC a logic of PLC’s directly drives the hardware allowing real time data acquisition. The control of the system is distributed and remotely accessible by a connection to a TINE device server. The commissioning phase has been done using a Labview TINE client application. The client is able to perform on-the-fly scans thanks to the PLC's base logic. In the following paper the different pieces of the system are presented as well as an overview of the instrument.

  The CODAS department of the Joint European Torus project has developed an application protocol for centralised simultaneous data acquisition, control and monitoring of a large number of processors. It is developed around the easy-to-use HTTP standard. The protocol has now been in use for about 5 years. It is intended to allow parallel, collaborative, developments to take place, by defining communication interfaces between systems. For this reason, it is referred to as the 'Black Box' protocol. The paper outlines the main factors that led to this protocol choice, and the benefits and experience gained. The paper briefly describes the functionality of the protocol, and explains how these are being used on a variety of platforms, including Windows, Linux, Solaris, VME, and PLCs.

  As part of a joint project CLS, the University of Western Ontario, IBM and BigBangwidth has developed a beamline remote access system that has been demonstrated on the CLS VESPERS and the alft x-ray source facilities. This system utilizes web-browsers as a thin client that can be connected to servers at the CLS over conventional Ethernet or User Configuration Light Paths. The RBA system is based on the concept of a Service Oriented Architecture and provides access control, data acquisition, data storage and based visualization. More recently the system has been modified to permit experimental data to be streamed into third party analysis tools such as Quartz Imaging X-one. This system is now being extended to form the basis for ScienceStudio and integrated experiment management system.

WEX04 An Embedded Distributed System Based on TINE and Windows CE controls, feedback 148

  We present an embedded distributed system based on the integration of the control system (TINE) inside an embedded-PC running Windows CE RTOS. As Windows CE is not Windows and requires a cross-compilation of the source modules, porting TINE to Windows CE turned out to be straightforward, but non-trivial. Having a dedicated Windows CE TINE library allows creating device servers inside the embedded operating system, close to the hardware application layer. The embedded-PC is the master of the hardware line, where different hardware devices are connected through a real-time Ethernet field bus. On the one hand there is a low level control of this hardware performed by a set of programmable logic controllers (PLC) running in fast cycling and on the other hand there is a higher level control performed by the TINE server devices. The server is the responsible of providing an interface to the external world, exporting the functionality of the system through the Ethernet control network. It is also possible that the server acts as a TINE client of other external servers, constituting a network of embedded nodes. We present a practical development that demonstrates the proposed system.

  At XFEL it is planned to install most electronic components and computers for LLRF, diagnostics and controls inside the tunnel. Access to these devices during the XFEL operation will not be possible. Remote control and monitoring of all relevant parameters of the shelfs/crates and the computers must be ensured and should be done in a standardised way. In addition software downloads and debugging up to the FPGA level should be provided, even if an operating system crashes e.g. due to radiation, maintenance functionality must be available. An introduction to xTCA will be given, the reasons to change the crate standard from a VME to a xTCA based system and the experience with this new electronics standard will be described.

WEP007 FESA - The Front-End Software Architecture at FAIR controls, diagnostics, ion, instrumentation 183
 
  • T. Hoffmann
    GSI, Darmstadt
  The planned Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is a very challenging task due to its dimension and complexity. Several new heavy ion accelerators have to be built and then operated in parallel and multiplexed modes. In order to cope with these unique requirements numerous collaboration partners are involved to add so-called ”in-kind contributions” to the project. Detailed guidelines and interface specifications have to be defined in advance to avoid an indefinite pool of different technologies which have to be handled by the future control system. For that purpose, GSI decided to use the Front-end Software Architecture (FESA) at the lowest level of the control system. FESA was developed by CERN and is already established for usage at LHC and its injectors. It is a framework to integrate any kind of equipment such as beam instrumentation devices, magnet power supplies, vacuum- and cryogenic components into the control system. A framework overview, its advantages, and boundary conditions provided by FESA are described.

  Among the candidate technologies for the Extremely Large Telescope (E-ELT) are ALMA Common Software (ACS) and LabVIEW. ACS is a CORBA-based control system infrastructure that implements a container-component model. It allows developers to focus on development of components that define application logic, with ACS-provided containers addressing infrastructural issues of distributed control systems such as remote procedure calls, logging, configuration, etc. LabVIEW is a commercial solution provided by National Instruments which allows rapid construction of user interfaces and control loops. Control loops can execute on Windows and Linux operating systems, as well as real-time control systems and FPGA circuits. In this paper, we present an approach for integration of ACS and LabVIEW. We accessed ACS from a LabVIEW user interface (both sending of data into ACS, and receiving data from ACS). Also, we accessed a real-time LabVIEW process (parts of which were executing in FPGA) from ACS – again in both directions. From the LabVIEW perspective, the approach is platform-independent as it is based on a Simple TCP/IP Messaging protocol.

  MicroIOC LR-BPM product offers complete beam position monitoring solution to be used on transfer lines or linear accelerators where bunch repetition rate is low (< 50Hz). It consists of Log ratio Beam position monitor (LR-BPM) modules from Bergoz instrumentation and of microIOC analog to digital acquisition unit (microIOC-ADA) from Cosylab. In this paper we present the detailed operation of the system and the results from testing that was performed at Soleil accelerator in May 2008. In this particular test microIOC LR-BPM proved to be a complete stand alone solution with only signals from the beam pickup detectors as inputs. It is capable of providing up to 8 X-Y beam positions and since its design is based on a single board computer inside the ADA unit it is easily integrated in a higher level control system software. Furthermore the position data is available to the control system clients over the external network via Ethernet link. EPICS was used as a control system although the product can accommodate other types of control systems that can run on x86 platform.

  • M. Pugliese
    ELETTRA, Basovizza, Trieste
  Modern science requires the most advanced Information and Communication technologies. Data generated by detectors and experimental stations have to be acquired, stored, processed, shared and visualized. Starting from the experience with the Elettra Virtual Collaboratory which allows a distributed team of researchers to carry out remote experiments using Elettra beamlines and with the contribution of EU funded research projects (GRIDCC, EUROTeV, DORII) we have developed a platform for E-Science applications. The platform is base on Grid technologies and allows the integration of sensors, instruments and other data sources to the computing and storage resources of the eInfrastructure / cyberInfrastructure and distance collaboration through a web portal called Virtual Control Room. The platform can be used in different contexts and supports the development of both scientific and industrial applications such as on-line processing of experimental data, environmental monitoring, remote operations and supervision of geographically distributed systems.

  TCP/IP is established as a de facto standard network-communication protocol. Development of the TCP/IP enables us to build a large-scale distributed control system. Recent accelerator-control system consists of many TCP/IP devices; not only computers, but also embedded devices such as digital multimeters, oscilloscopes, multi-channel analyzers, and so on. Since these embedded devices are designed with limited hardware resources, most devices use subset of the TCP/IP components. The limited resources and components therefore cause many problems such as vulnerabilities of TCP/IP implementations. In SPring–8, by increasing the number of network-connected instruments with latent vulnerabilities, more trouble have arisen such as packet flooding and unexpected response delaying. One of the most serious trouble is hang-up of pulse-motor controllers* based on embedded operating system. To determine cause of the trouble, network-connected instruments were inspected using basic TCP/IP tools and security scanners. As a result, we successfully found vulnerabilities of embedded implementation. In this presentation, the cause of vulnerabilities in embedded systems will be discussed.
