TCP (Transmission Control Protocol)

TCP (Transmission Control Protocol) provides reliable connection-oriented network

communication with error checking. In TCP mode the Modbus gateway can be

configured as a client or a server.

When the Modbus gateway is configured as a TCP client it initiates connections with a

server on the network. You must set up the IP address and port number of the server that

you want the client (Modbus gateway) to communicate with. You also select whether the

Modbus gateway is to connect at power up or only when it receives data from the device

connected to its serial port.

When the Modbus gateway is configured as a TCP server it waits for connections to be

initiated by another network device. You must set up the TCP port number that it will

listen to for connections and set the maximum (up to eight) number of simultaneous

connections it will accept. You can filter the connections it will accept based on specific

IP addresses or ranges of IP addresses that you specify.
