Can you give me your program to reference? Thanks you for your support ! Hello, with the Modbus driver a sample project is installed in the Simatic manager. I recommend to use that. And evaluate the outputs of the FBs and the diagnostic buffer of the CP. Regards, Kaulquappe

Alternativly I canoffer youmy blocks if you are interested. My software does not require a hardware dongle in the CP341 and is very simple to use, esspecially for beginners. Best Regards.
