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. **) With the 840D, the NCK digital inputs and outputs 1 to 4 are provided as onboard
hardware inputs and outputs. These can be processed by the PLC according to *).
