All large scale particle accelerator facilities end up utilising computerised safety systems for the accelerator access control and interlock system including search lockup sequences and other safety functions. Increasingly there has been a strong move toward IEC 61508 based standards in the design of these systems. CLS designed and deployed its first IEC 61508 based system nearly 10 years ago. The challenge has increasingly been to manage the complexity of requirements and ensure that features being added into such systems were truly requirements to achieve safety. Over the past few years CLS has moved to a more structured Hazard Analysis technique that is tightly coupled and traceable through the design and verification of its engineered safety systems. This paper presents the CLS approach and lessons learned.

A Rational Approach to Control System Development Projects That Incorporates Risk Management

Over the past year CLS has migrated towards a project management approach based on the Project Management Institute (PMI) guidelines as well as adopting an Enterprise Risk Management (ERM) program. Though these are broader organisational initiatives they do impact how controls systems and data acquisition software activities and planned, executed and integrated into larger scale projects. Synchrotron beamline development and accelerator upgrade projects have their own special considerations that require adaptation of the more standard techniques that are used. Our ERM processes integrate in two ways: (1) in helping to identify and prioritising those projects that we should be undertaking and (2) in helping identify risks that are internal to the project. These broader programs are resulting in us revising and improving processes we have in place for control and data acquisition system development and maintenance. This paper examines the approach we have adopted, our preliminary experience and our plans going forward.

The Canadian Light Source has ongoing work to improve the user interfaces at the beamlines. Much of the direction has made use of Qt and EPICS, using both C++ and Python in providing applications. Continuing work on the underlying data acquisition and visualization tools provides a commonality for both development and operation, and provisions for extending tools allow flexibility in types of experiments being run.

Alarm management systems promise to improve situational awareness, aid operational staff in correcting responding to accelerator problems and reduce downtime. Many facilities, including the Canadian Light Source (CLS), have been challenged in achieving this goal. At CLS past attempts focusing on software features and capabilities. Our third attempt switched gears and instead focused on human factors engineering techniques and the associated response processes to the alarm. Aspects of ISA 18,2, EEMUA 191 and NREG-700 standards were used. CLS adopted the CSS BEAST alarm handler software. Work was also undertaken to identify bad actors and analyzing alarm system performance and to avoid alarm flooding. The BEAST deployment was augmented with a locally developed voice annunciation system for a small number of critical high impact alarms and auto diallers for shutdown periods when the control room is not staffed. This paper summaries our approach and lessons learned.
