Communication Basics
(OP)
Hello,
I'm trying to understand communications in the utility field. The protocols available, transport method, physical media. I'm not sure if I exactly understand the above, But I believe the transport method is either RS 485 or RS 232, the media is air,fiber, bus (PLC) and the protocol is DNP 3, or Modbus. Does anyone know of a tutorial that explains this in simple terms, the differences of protocols ?
thanks
