4.11 Modbus TCP
The WI-MOD-xxx-E-5W also has an on-board Modbus TCP server and Modbus TCP client that provide connectivity
for a range of Modbus applications. The Modbus TCP client and the Modbus TCP server can be enabled
simultaneously, and when combined with the built in Modbus TCP/RTU converter (enabled on the Serial page) the
WI-MOD-xxx-E-5W can transfer I/O to and from almost any combination of Modbus TCP or RTU devices.
Modbus TCP Server
The Modbus TCP server enables the WI-MOD-xxx-E-5W to accept connections from Modbus TCP clients. To
configure the Modbus TCP server, click Modbus TCP on the menu, and then click Modbus TCP Server to
display the page in Figure 59.
All Modbus transactions routed to the onboard Modbus TCP server are directed to/from the onboard general
purpose I/O registers. Because the Modbus TCP server can also be shared with the Modbus TCP/RTU converter (if
enabled), the
“Device ID” must be a unique address—which is why the default is set to 255. Care should be taken
