	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.

WEZ02	The Canadian Light Source Control System - A Case Study in the Use of Single Board Computers and Industrial PC Equipment for Synchrotron Control	157

	Since 2000 the Canadian Light Source (CLS) control system architecture has been based on to the use of small single board computers for equipment control running the RTEMS operating system. CLS has started to migrate to a new off-the-shelf single board computer platform (based on the Moxa embedded computer platform. In 2001 CLS also adopted the use of fibre optic bridges and industrial PC equipment in place of VME slot zero controllers. Today this continues to be the basis of our higher performance data acquisition and control applications. This paper outlines the lessons learned from nearly eight years of operational use of the this technology.

THX04	CLS Safety Systems	227
	R. Tanner, E. Matias, H. Zhang CLS, Saskatoon, Saskatchewan
	The Canadian Light Source has adopted the use of IEC 61508 SIL 3 certified equipment and associated methods in the development of safety critical software. This paper examines the successful application of industrial safety rated PLC equipment in the development of accelerator and beamline safety systems. Of specific note is the application of this technology to a biomedical beamline at the CLS.
