WECOAA04	Employing RTEMS and FPGAs for Beamline Applications at the APS	controls, coupling, power-supply, instrumentation	27
	D. M. Kline, S. K. Ross ANL, Argonne
	At the Advanced Photon Source (APS), the power and flexibility of an Altera Cyclone-II FPGA combined with the Arcturus uC5282 embedded microprocessor running RTEMS, provides a low cost solution for implementing beamline applications. In this paper, we discuss the approach of coupling an Altera FPGA and the Arcturus uC5282 to implement a time-resolved 32-channel scaler, development using the Altera Quartus-II design environment and the RTEMS tools, as well as an ASYN based EPICS device driver and its integration to the standard scaler record support. Furthermore, we discuss how this approach has been applied to other control system applications, such as for photon counting and flexible CCD shutter timing control. By employing this approach, a variety of applications can be quickly developed on one hardware platform which realizes real-time performance within the FPGA and provide a cost effective EPICS IOC for exporting data to scientists and users.

WEPL009	Integration of Programmable Logic Controllers into the FAIR Control System using FESA	controls, radiation, ion, antiproton	44

	For the upcoming 'Facility for Antiproton and Ion Research' (FAIR) at GSI, the Front End Software Architecture (FESA) framework built by CERN has been chosen to serve as front-end level of the future FAIR control system. All future beam diagnostic devices will be controlled by FESA classes that are addressable by the new control system. The connectivity to the old control system is retained, since both control systems will be in operation contemporaneously for several years. Commercially available Programmable Logic Controllers (PLCs) have been installed as part of beam induced fluorescence (BIF) monitors to replace outdated network attached devices and to improve the reliability of the BIF systems. The new PLC devices are now controlled by FESA classes which are addressed from the existing C++ software via RDA calls. This contribution describes the system setup and the involved software components to access the PLC hardware.

WEPL022	STARS on PLC	controls, factory, monitoring, vacuum	73
	T. Kosuge, K. N. Nigorikawa KEK, Ibaraki
	STARS (Simple Transmission and Retrieval System) is a message transferring software for small scale control systems with TCP/IP sockets, which works on various types of operating systems. We have succeeded to run STARS server and client on PLC (Yokogawa FA-M3, CPU module F3RP61) this time. At present, PLCs are used for beamline interlock systems (BLIS) and PCs are used for monitoring system (CCS) of BLISs at the Photon Factory. Running STARS on PLC brings capability of BLIS and CCS integration. We will describe detail of "STARS on PLC".
WEPL033	EPICS IOCcore Real-Time Performance Measurements on Coldfire Module*	target, controls, site	94
	S. Xu, R. Laird, F. Lenkszus, H. Shang ANL, Argonne
	Since EPICS (Experimental Physics and Industrial Control System) is gaining use in accelerator control systems and because the EPICS Input/Output Controller (IOC) has been ported to different operating systems, the performance of EPICS IOCcore on different hardware and software platforms is becoming important. This paper will provide real-time performance measurements of EPICS IOCcore on a Coldfire module uc5282 and two different OS platforms: RTEMS 4.9 and uClinux 2.6. The most recent EPICS base and extensions are used to build the test application.

THCOMA02	synApps: EPICS-Application Software for Synchrotron Beamlines and Laboratories	synchrotron-radiation, controls, diagnostics, feedback	106
	T. Mooney ANL, Argonne
	synApps is a collection of EPICS-application software originally intended to support the needs of scientists working at synchrotron-radiation beamlines. The collection contains general purpose software that extends or exploits capabilities of EPICS base, and a large amount of instrument-specific software that applies EPICS to control and provide a user interface for off-the-shelf electronics. This presentation will provide an overview of synApps, describe how synApps is deployed at the Advanced Photon Source, and highlight recent additions to the collection.

THCOAA01	Web Services Cyber-Security Issues	controls, monitoring	115
	D. E.R. Quock ANL, Argonne
	The Web’s potential for distributed programming has been proven not only in the business realm, but also in the accelerator controls domain. Web Services describes clients and servers that communicate over the Internet’s Hypertext Transfer Protocol (HTTP) using predefined Internet-based Application Programming Interfaces (APIs). It is the uniqueness of Web Services transactions such as cloud computing, data sharing, and data archiving that give rise to the security concerns of Web Services (authentication, data integrity, non-repudiation, and privacy). At Argonne National Laboratory’s Advanced Photon Source, Simple Object Access Protocol (SOAP)-based Web Services were implemented into the Integrated Relational Model of Installed Systems (IRMIS) as the application interface to Oracle’s Content Server document management software. This report reviews the basics of Web Services, cyber-security issues that are inherent for Web Services, current Web Services security implementation practices, and future directions of Web Service security development efforts where the overriding goal of Web Services security is to focus on managing risk and protecting data.

THCOAA04	Diamond's transition from VME to fieldbus based distributed control	controls, instrumentation, vacuum, optics	124
	I. J. Gillingham, T. M. Cobb, P. Hamadyk, M. T. Heron, S. C. Lay, R. Mercado, M. R. Pearson, N. P. Rees Diamond, Oxfordshire
	The interface lay of Diamond's accelerator and photon beamline control systems have predominately been implemented as VME based systems. Forthcoming control systems, for new photon beamlines, have requirements necessitating a divergence from Diamond's adopted design patterns, including a reduction in available rack space and the management of hardware obsolescence. To address these, a new standard based on PCs and Ethernet field buses to the instrumentation has been defined. This paper will present the new design, how the design transition is being effected and the key benefits to Diamond.

THPL023	Data Acquisition and Studies of Vibration Motion in TLS Beamlines	electron, site, controls, feedback	177
	P. C. Chiu, J. Chen, Y. K. Chen, K. T. Hsu, K. H. Hu, C. H. Kuo NSRRC, Hsinchu
	TPS (Taiwan Photon Source) is being under construction while TLS (Taiwan Light Source) is still on operation at the same NSRRC site. It was observed that the stability of photon beam intensity (Io) of TLS seemed a little deteriorated at daytime, when civil work is busy, compared to the nighttime. The intensity changes at different beamlines, however, aren’t consistent with each other in each time, furthermore not so agreeing with the electron beam. Therefore, to correlate how the ground vibration due to civil construction effected on beam behaviour, the vibration measurement system is integrated into the existing TLS control system. The system will support waveform acquisition which could be acquired on demand. Meanwhile, realtime 10 Hz rms detector which could be archived continuously is also considered to be built in the future.
