Hello. Did this work for you? I am trying to communicate with a charge controller that supports modbus/tcp but when I modify code above I don't even see traffic leave my host. I get a response from the program that looks like "Response: ModbusRequest PDU(000000000006ff040001000a)" but I don't know what that means. I am going crazy over this. Please help. Thank you.
