Hello e_skazem, 

Attached snap is of connectors on PPU i.e. X122 & X132 is of DI/DO for drive. X242 & X252 id DI/DO for NC. I guess you want to know if these NC DI can be configured as PLC input? If correct, answer is - not recommended as PLC input. NC inputs are fast inputs & you need read those in PLC logic. You can configure PP module to connect DI/DO as PLC input/outputs.
