Figure 26 - Safety Task Status
These are the possible values for safety status:
•
Safety partner is unavailable.
•
Safety firmware is incompatible.
•
Safety task inoperable.
•
Safety task OK.
With the exception of safety task OK, the descriptions indicate that
nonrecoverable safety faults exist.
See
Major Safety Faults (Type 14) on page 108
for fault codes and corrective
actions.
Controller Faults
Faults in the Compact GuardLogix system can be nonrecoverable controller
faults, nonrecoverable safety faults in the safety application, or recoverable safety
faults in the safety application.
Nonrecoverable Controller Faults
These occur when the controller’s internal diagnostics fail. If a nonrecoverable
controller fault occurs, safety task execution stops and CIP Safety I/O modules
are placed in the safe state. Recovery requires that you download the application
program again.
Nonrecoverable Safety Faults in the Safety Application
If a nonrecoverable safety fault occurs in the safety application, safety logic and
the safety protocol are terminated. Safety task watchdog faults fall into this
category.
