A default SIS SRS is provided within ProSET.

The SIS requirements are split into 6 sections:

Below are the fields within each section.

SIS Details

  • Operator Interface
  • SIS / Basic Process Control System (BPCS) interface

Process Details

  • Normal Plant Operation
  • Abnormal Plant Operation

SIL Data

This describes the SIL target for the SIS, which is automatically taken from the SIL Determination module, and provides information on the target proof test interval and mean repair time of the SIS.

  • SIS SIL Target
  • SIS Target Proof Test Interval (Months)
  • SIS Mean Repair Time (Hours)

Trip Actions

  • Operator Interface

Application Software

  • Logic Solver Software Type
  • Application Software Self Monitoring
  • Functions To Enable Periodic Testing
