The PLC user program recognizes from the 0/1 edge of the signal DB43xx.DBX0.0 (job) that a
new job has been assigned by the tool management.
The PLC user program sets the acknowledgment signal in DB42xx.DBX0.0 (total acknowledg‐
ment). With activation of the 0/1 edge, the PLC firmware starts transferring the acknowledgment
to the tool management.
After successful transmission of the acknowledgment to the tool management, the PLC firmware
sets a PLC cycle to 1 for the signal "acknowledgment OK" and at the same time the job signal
and the acknowledgment bit are reset to 0.
