Error: Module 'MPI/DP': Local partner does not support S7 connections.
Warning: Local ID '1': The configured interface operating mode combined with the set 'DP' profile of PROFIBUS 'PROFIBUS(1)' may affect the communication via the S7 communication.
Warning: "'S7 connection', ID '1': For this uploaded connection, there is no need for the functions 'Compile' and 'Load PLC' because the connection was still not modified after upload to the programming device.
