The following applies to cyclic tasks with watchdog activated:
Reference for Watchdog Settings!
For each tasks created, a watchdog can be enabled that monitors the execution

If the task runtime exceeds the specified watchdog time (e.g., t#200 ms), then
the watchdog event has occurred.
The runtime system stops the IEC program and reports an error.

If the watchdog time set is greater than the call interval of the task, then the
watchdog is restarted for each task call interval.
