SFM is an OpreX™ Asset Operations and Optimization solution that helps identify whether actual operating performance meets safety design targets. SFM R3.35 provides continuous monitoring and evaluation of safety data to highlight deviations or failures in safety system performance and supports IEC 61511 standards with several new features including:
Cause and Effect matrix to quickly verify the logic of SIF activations and Final Elements (valves, vents, actuators, etc.) actuations to see if they match their configured or intended safety design
Enhanced proof testing by claiming proof test credit based on actual demand on the SIS during operation for SIF activations and Final Element actuations, with the functionality to record when proof tests have taken place and to monitor expiry dates of proof tests.
