Using Engineering Automation Software to Document Safety Instrumented Systems

摘要

A case study of experiences in using Engineering Automation tools to document Safety Instrumented Systems field wiring and system parameters. The special requirements of SIS wiring presents some changes in how the automation tools are used and the work practices that need to be applied to support the documentation required by the owner operators. This paper will address issues such as identifying SIS I/O and maintaining system integrity within the Automation System database. Special data fields which are needed in the Automation System to reference the SIS control system and wiring will be identified. This paper will also discuss how the Automation Software is changing to accommodate SIS and other unique aspects of modern instrument wiring matrixes. The paper will conclude by looking at the deliverables generated by the Automation Software to support critical alarms, shutdown systems and PLC configurations.
