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.
