If the NC control unit of the machine switches the E-stop input of the DLC off when the UD contact is open, then the message
"E-stop" is stored with each powering down. The NC control unit of the machine can, during the course of one program cycle and
prior to starting the program, clear the message "E-stop" with a CLEAR signal. Under some circumstances, error diagnoses can be
cancelled. It is not necessary to switch the E-stop input of the DLC off as part of a general powering down. As part of a general
powering down, the NC controls of the machine can, for example, suppress the evaluation of the UD contact. The NC control of the
machine cannot, however, start the program if the UD contact is closed.
