DBX104.7 NCK CPU ready
Signal state 0 The NCK CPU is not ready.
If a sign-of-life is not received from the NCK, the PLC/NCK interface is neutralized by the PLC basic
program and the interface signal "NCK CPU Ready" is set to 0.
The following measures are introduced by the PLC basic program:
● Status signals from NCK to PLC (user interface) are deleted (cleared)
● Change signals for help functions are deleted
● Cyclic processing of the user interface PLC to NCK is terminated.

DBX108.5 Drives in cyclic operation
Edge evaluation: No
Signal state 1 For all machine axes of the NC, the corresponding drives are in the cyclic operation, i.e. they cyclically
exchange PROFIdrive telegrams with the NC.
Signal state 0 For at least one machine axis of the NC, the corresponding drive is not in cyclic operation, i.e. it is
not cyclically exchanging PROFIdrive telegrams with the NC.

DBX108.6 Drive ready
Edge evaluation: No
Signal state 1 For all machine axes of the NC, the corresponding drives are ready:
DB31, ... DBX93.5 == 1 (DRIVE ready)
Signal state 0 For at least one machine axis of the NC, the corresponding drive is not ready:
DB31, ... DBX93.5 == 0 (DRIVE ready)
Corresponding to ... DB31, ... DBX93.5 (DRIVE ready)
