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.
