MOD006	Migrating Control Servers and Applications to Virtual Machines	43
	G. Wright, C. Angel, C. Finlay, E. Matias CLS, Saskatoon, Saskatchewan
	At the Canadian Light Source, there are an ever-increasing number of distributed Controls applications that can run on generic networked computers. This has led to additional servers when segregation by operating system or by LAN has been required. Additional concerns of maintenance of older computer hardware, driver support for older O/S's on new hardware, and growing Virtual LAN issues have led to an adoption of moving applications to Virtual Machines. Our implementation using VMware Infrastructure provides a high reliability environment, with centralized monitoring of performance and simplified expandability. The distributed 'average' reliability hardware has been replaced by a single high-reliability system with built-in redundancies. A new virtual machine can be started in a matter of minutes from an existing pre-configured template, and can be joined to up to four VLANs with a simple software configuration.

TUP047	The Use of Process and Instrumentation Drawings for Accelerator and Beamline Control Applications at the Canadian Light Source	191
	E. Matias, G. Judkins, M. McKibben, J. Swirsky CLS, Saskatoon, Saskatchewan
	In 2001 at the start of the Canadian Light Source Project, the CLS began to adopt the use of Process and Instrumentation Drawings not only for process systems but also for accelerator and beamline optical components. Given existing industry standards have only been formulated for process applications this posed unique challenges. This paper describes the internal standards that were adopted, how they evolved over the past nine years and operation benefits we have been able to achieve through the use of PID drawings. The paper also examines the benefits from using AutoCAD scripts to automate the implementation of PID drawings.
TUP075	Canadian Light Source - Phase II Beamline Control System Status Update	254
	E. Matias, D. Beauregard, R. Berg, G. Black, W. Dolton, R. Igarashi, T. Wilson, G. Wright CLS, Saskatoon, Saskatchewan
	The Canadian Light source is in the final commissioning stages of its six Phase II beamlines. These beamlines make use of both EPICS based control as well as experiment data acquisition using a common underlying framework. This paper outlines the approach adopted in deploying control system on this phase of beamlines. The beamline control system make extensive use of QT toolkit and EDM for operation screens and the CERN Root package for data visualization.
WEP052	Experience with Motion Control Systems at the Canadian Light Source	501
	D. Bertwistle, E. Matias, M. McKibben CLS, Saskatoon, Saskatchewan
	Devices requiring a motion control system are ubiquitous at the Canadian Light Source. The most numerous devices requiring control are found within the scope of beamlines and vary from simple slits to instruments as complex as endstations. A VME based motion control system has been implemented that is flexible, manageable, and relatively low cost. A general overview of the system is presented with advantages and disadvantages put forward.
WEP108	Contribution of the CLS Control System to the CLS Accelerator System Reliability	603
	E. Matias, H. Zhang, M. S. de Jong CLS, Saskatoon, Saskatchewan
	The control system software plays an increasingly important role in achieving overall accelerator system reliability, in this regard the CLS control system is no different. This paper reviews the two aspects of control system reliability (1) the reliability of the control system itself and it contribution to system reliability and (2) the use of the control system as a tool to aid in predicting and localizing system failure therefore providing an indirect impact on mean-time-between-failure and mean-time-to-repair. The paper provides a survey of metrics used at the CLS to evaluate system reliability, several failure modes that have been localized and removed from the system design to contribute to overall reliability. Recently CLS has deployed a new approach to alarm annunciation and fault location based on voice annunciation and nested dashboard display screens.

	As part of a joint project the Canadian Light Source, the University of Western Ontario, IBM and Concordia University are in the process of building an integrated experiment management system. This system utilizes web-browsers as a thin client that can be connected to servers at the CLS over conventional Ethernet or User Configurable Light Paths. The system is based on a Service Oriented Architecture and provides access control, data acquisition, data storage and data visualization. More recently work on the system has included implementation of user office functionality, integrated control of an EPICS based beamline and analysis codes.
