Calculate the difference time and give it to the soft PLC

Pull overtravel fault:

GLOBAL REAL max_sf=15.0 Maximum deviation value

$softplcreal[20]=max_sf

sf_prog_status Delayed fault program status

$ASYNC_STATE Additional axis status

Therefore, we can conclude that one of the two control units of the pulling fault is the difference value max_sf=15.0, and the other difference time TotzeitNeu is given to the PLC. Therefore, the conditions for the pulling fault in the program are generated.
