Signals to NC (DB10)

Overview of signals from PLC to NC
DB10 Signals to NC interface PLC → NC
DBB Bit 7
0 Disable digital NCK inputs
Digital inputs without hardware *)
Input 8
1 Setting by PLC of the digital NCK inputs
Digital inputs without hardware *)
Input 8
4 Disable digital NCK outputs
Digital outputs without hardware *)
Output 8
5 Overwrite screen form for digital NCK outputs
Digital outputs without hardware *)
Output 8
6 Set value by PLC of the digital NCK outputs
Digital outputs without hardware *)
Output 8
7 Setting screen form for digital NCK outputs
Digital outputs without hardware *)
Output 8
Notes:
*) Bits 4 to 7 of the digital NCK inputs/outputs can be processed by the PLC even though there are no equivalent hardware
I/Os. These bits can therefore also be used for data exchange between the NCK and PLC.
**) The NCK digital inputs/outputs 1 to 4 are provided as onboard hardware inputs and outputs.
