Outputs:
• All signals or values to be output are also transferred to the PLC.
• The NCK can also transfer signals or values to the PLC even if there is no hardware for
this channel on the NCK side.
• The values transferred by the NCK can be overwritten by the PLC.
• Signals and values from the PLC can also be output directly via the NCK I/O devices.
Note
When implementing digital and analog NCK I/Os, you must observe the information in the
following references:

Signals PLC/mode group
The operating mode signals set by the machine control panel or the MMC are transferred to
the operating mode group (mode group). The mode signals are valid for all NC channels of
the mode group on the 810D and 840D. On 840D systems, several mode groups can
optionally be defined in the NCK.
The mode group reports its current status to the PLC.
