Monitor Safety Status
View controller safety status information on the safety status button on the
online bar and on the Safety tab of the Controller Properties dialog box.
Figure 42 - 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 183
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.
