Good luck Nit

I try to put the Step7 communications connector on the X122 but no success. I stopped at this point.

If you don't have the MPI lightening you must check if you have external 24V on the X121 connector. Good luck Nit

X121 pin 1 24V - X121 pin 20 24V + if you've done a reset with S3 / S4 after commissioning instructions is no PLC program in the NCU the error message 2001 to the HMI is quite normal because the HMI does notcommunicate with the PLC the PLC Base Program is missing you have to load the PLC Program
