Recommendation: Into task levels PLC1_BEARB and PLC_BEARB, because
these levels are directly triggered.
Note: If you use this block in the task levels MW_BEARB and SFS_BEARB, a
change of the SWITCH signal is only recognized if the signal lasts longer than
the processing cycle of the task level.

Limit
32
If the limit is exceeded, the device rejects the parameter set
with an error message, restores the last valid parameter set
and restarts using that parameter set.
16
When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
400
When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
350
When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
