Note
After communication between the PLC and NC (read/write NC variables, FB2, 3, 5, or PI
general services, FB4) has been aborted by POWER OFF, the start jobs must be deleted in
the first OB1 run after cold restart or reset (signal: Req = 0).
FB 5 can read GUD variables only if basic program parameter NCKomm has been set to "1"
FB 1, DB 7).
