Notes:
*) Bits 4 to 7 of the digital inputs and NCK outputs can be processed by the PLC although no equivalent
hardware I/Os exist. 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.
