Modbus TCP

2. Modbus TCP

A standard simple network with a single Master and several Slaves running Modbus TCP. A TCP/IP connection is established and maintained between Master PLC and Slave RTU across the entire radio network.

In Bridge mode, no special setup is required. RipEX operates as an intelligent Bridge. For more information refer to on-line help or chapter ETH / Modbus TCP of the manual.

In Router mode, routing must be set up in the radio network. Communication between the IP address of the Modbus Master and IP addresses of all Modbus Slaves is necessary. Remember to set Modbus TCP/RTU and Terminal Servers (under Settings/Ethernet) to Off.
