Hi, I’m trying to establisch communicate with a Modbus TCP slave. I need to reed address 3201 by using FC3. For some reason I always get error “illegal data address”. I have double checked the addressing (Unit ID = 0, FC3, offset 3201) with an external Modbus TCP tool and this works. Do I miss something within the Codesys configuration
