Chapter 5 Characteristics of Safety Tags, the Safety Task, and Safety Programs
The safety task period is limited to a maximum of 500 ms and cannot be
modified online. Make sure that the safety task has enough time to finish before
it is triggered again. Safety task watchdog timeout, a non-recoverable safety fault
in the GuardLogix controller, occurs if the safety task is triggered while it is still
executing from the previous trigger.
See Chapter 7
, Monitor Status and Handle Faults, for more information.
