NCK
The digital I/O peripherals (e.g. 6 digital inputs of Central Service Board or maximum 2 mixed
I/O modules with 2 input and output bytes each) can also be used to a limited extent in the
NCK area.
The status of these inputs/outputs can be read from the PLC by means of the high-speed data
channels. However, the outputs cannot be written from the PLC!
