Chapter 9 Monitor Status and Handle Faults
Capture Fault Information
The SafetyStatus and SafetyTaskFaultRecord attributes can capture information
about non-recoverable faults. Use a GSV instruction in the controller fault
handler to capture and store fault information. The GSV instruction can be used
in a standard task in conjunction with a controller fault handler routine that
clears the fault and lets the standard tasks continue executing.
