Hi
I have a gaurd logix system with L73S and safety partner L7SP.
1756-L73S 1756-L7SP faulted with major Error Type 14 Code 01 and after clearing the fault, when controller put in run mode, again faulted with error type 14 code 07.
I have checked technote 46434 and 68112, and checked the points given in both technotes. but could not found a reason in the program which can cause the watchdog time expire.
The program has contineus task and safety task. safety task has logic in it.
system is installed and running from 8 months, this is the first occurence of this type of fault.
Can you suggest what can cause safety task watchdog expired.
