hi I Have one basic doubt,I was reffering the specification of MODBUS TCP, I got confused. According to my understanding, the controlling device i.e the RTU(Real Time Unit) will be the slave and the one who request(poll) for the data is the master. But in case of client/server concept the one who serves the request(RTU) will be the server and one poll for the data is the client.
Please clarify my doubt Thanks in advance Prasi
