| THD001 | Integrating High Level Applications and Software Components Using a SCADA Tool | 904 |
|
||
|
To build integrated high level applications, SOLEIL is using an original component oriented approach based on GlobalSCREEN*, an industrial Java SCADA. The first kind of components is made up on top of the ATK (Application Tango Toolkit) library: a rich set of Java graphical widgets, including scientific data visualization tools, and encapsulating TANGO communication. More complex components are Java Rich Client applications providing a high level of service and ergonomic layouts to the end user: data logging access, scanning services, sequencing setup and control. Packaged as JavaBeans in GlobalSCREEN's components library, all these components are ready to use by means of drag-dropping and properties configuration to connect them to the control system. So, using GlobalSCREEN as a Rich Client Platform allows non experienced developers to quickly build, without writing any Java code, very complex and fully integrated applications dedicated for example to the end users of a beamline. The work organization, the software architecture and design of the whole system will be presented, as well as the current status of deployment at SOLEIL for the Accelerators and the Beamlines.

| THD002 | A Mobile Platform for Remote Inspection Inside ESRF Tunnel | 907 |
|
||
|
A light source has to provide beam 24h/24h x 7 days. Numerous sensors have been installed to detect hardware failures, fires, water leaks etc' Unfortunately, with aging we are sometimes faced to false alarms. Then, visual inspection is sometime necessary to confirm or evaluate an alarm. ESRF in collaboration with the Tampere University of Technology (TUT/IHA)* and expertize from ROVIR** is developing a autonomous vehicle remotely controlled via WiFi. It is able to travel all along the tunnel, with beam ON, and transmit live image of a high definition video camera. Thanks to a virtual reality software, the operator is able to send the platform to any location of the tunnel. The platform should be able to get energy autonomy, to automatically recharge its battery, to react to unforeseen situations, to avoid collisions, and to do self learning of its environment. One of the goals of the collaboration is to design this tool in such a way that it can become a commercial product available at low cost for any light source. This paper describes the hardware and the software issues of this platform and describes how ESRF and TUT are collaborating in view of building this tool.

| THD003 | UNICOS: An Open Framework | 910 |
|
||
| In early 2001 an object collection called UNICOS (Unified Control System) developed at CERN with the objective of building the LHC cryogenics control system was commissioned for the first time. It deployed the controls layers covering the SCADA (Supervisory Control And Data Acquisition) and the PLC (Programmable Logic Controllers) layers. A possibility of re-targeting the system on other kinds of applications and environments was identified. Since then, the framework proposes a reusable environment composed of a set of components for the SCADA part and several solutions for the front end part (i.e. others than PLC). Together with the description of the UNICOS environment, the paper describes a number of very different applications developed at CERN based on the UNICOS methodology: (1) SURVEY, to align the focusing magnets of the LHC located on both sides of the experiments; (2) Quench Protection System, to display and act on the devices used to protect the superconducting elements of the LHC; (3) Powering Interlock Controller, to manage the powering permissions of the electrical circuits making the LHC. | ||
| THD004 | Options for Interfacing EPICS to COTS Hardware Through LabVIEW | 913 |
|
||
| Over the years, many have developed custom drivers to interface hardware to EPICS Input Output Controller (IOC). With LabVIEW having native drivers for supporting commercial hardware, development time can be reduced if an interface with LabVIEW and EPICS IOC was developed. This paper examines the different ways of interfacing LabVIEW and EPICS IOC both on VxWorks and Windows operating systems. Implementation of the Channel Access (CA) server on LabVIEW will also be covered along with the advantages and limitations of such an approach. The paper will also list the status of the different implementations at Oak Ridge and Los Alamos National Laboratory. | ||
| THD005 | Application of EPICS on F3RP61 to Accelerator Control | 916 |
|
||
| A new type of Input / Output Controller (IOC) has been developed based on F3RP61, a CPU module of FA-M3 Programmable Logic Controller (PLC). Since the CPU module runs Linux as its operating system, it takes no special effort to run EPICS IOC core program on the CPU module. With the aid of wide variety of I/O modules of FA-M3 PLC, the F3RP61-based IOC has various applications in accelerator control, such as magnet power supply control, monitoring interlock system, stepping motor control, data acquisition from beam monitors and so forth. The adoption of the new IOC makes the architecture of accelerator control systems simpler by unifying the two layers of front-end computers, i.e., the IOC layer and the PLC layer, into one layer. We found that the simplification of the control system architecture helps us to reduce the time and cost for the development and maintenance of the application software. | ||
| THD006 | Cryogenics Controls in the ISAC-II Superconducting RF Accelerator | 919 |
|
||
| The TRIUMF ISAC-II superconducting heavy ion linear accelerator is composed of eight cryomodules containing a total of 40 superconducting radio frequency cavities. This paper describes the control system for delivery of liquid Helium and liquid Nitrogen, and quench protection of accelerator components. We discuss integration of the ISAC EPICS-based control system with the control systems for two turn-key Helium refrigerators, details related to the delivery system and it's interface to other accelerator elements. Anticipated and ongoing control system upgrades are described. |
