Instance Codes and Last-Failure Codes
Instance codes identify and accompany significant events that do not cause the
controller to terminate operation; last-failure codes identify and accompany failure
events that cause the controller to stop operating. Last-failure codes are sent to the
host only after the affected controller is restarted successfully.
Controlling the Display of Significant Events and
Failures
You can control how the fault-management software displays significant events and
failures with FMU’s SET command.
