Hello BADR3, Well, in the past, I „played“ a little bit with S7-1500 and WP231 via Modbus TCP. Attached you can find my test TIA-project. In my project it was possible to read and write data. I executed my commands manually with the Watch table „MODBUS_Watchtable“. I don’t know, but maybe my test TIA-project will help. You have to change the ".txt" to ".zap14".
