Ready signal to PLC

DB10 DBX104.7 (NCK CPU ready)
The NCK CPU is ready and registers itself cyclically with the PLC.
DB10 DBX108.3 (HMI - CPU at OPI ready)
SINUMERIK Operate is ready and registers itself cyclically with the NC.
DB10 DBX108.5 (drives in cyclic operation)
Requirement: For all machine axes of the NC, the associated drives are in the cyclic operation,
i.e. they cyclically exchange PROFIdrive telegrams with the NC.
DB10 DBX108.6 (drive ready)
Requirement: For all machine axes of the NC, the associated drives and also the third-party
drives are ready via PROFIBUS:
DB31, ... DBX93.5 == 1 (drive ready)
DB10 DBX108.7 (NC ready)
The NC is ready.
