5.2 Fault Diagnostics
Note
Channel-related diagnostics are always updated to the current diagnostic function in the
diagnostic message frame. Subsequent, older diagnostic functions are not deleted.
Remedy: Evaluate the valid current length of the diagnostic message frame in
the RET_VAL parameter of SFC13.
Possible Fault Types of Fail-Safe Modules
