Cause and
correction
Assumed cause Correction Prevention
The watchdog time was set
incorrectly
If the watchdog time of the safety
process data communications set-
ting is set to a value inappropriate
for the communications cycle or
the configuration, correct it, and
transfer the setting to the Safety
CPU Unit.
Set the watchdog time in consider-
ation of the actual configuration
and surrounding environment.
The processing was not com-
pleted within the watchdog time
because communications were
not established due to the noise
If there is no improvement after
you performed noise countermea-
sures, set the longer watchdog
time, and transfer the setting to the
Safety CPU Unit.
