Chapter 12 Monitor Status and Handle Faults
Access FaultRecord Attributes
Create a user-defined structure to simplify access to the MajorFaultRecord and
SafetyTaskFaultRecord attributes.
For more information on using the GSV and SSV instructions, refer to the I/O
Instructions chapter of the Logix Controllers Instructions Reference Manual,
publication 1756-RM009
.
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.
