5.4

Modbus

The Gateway supports both Modbus RTU over the RS-485 serial port and Modbus TCP over
Ethernet. It functions as a sub device on the Modbus network and must be polled by a
Modbus master or client (host system).

5.4.1

Communication settings

It is import that the Modbus communication settings in the Gateway match the setting in
the Modbus master or client. Refer to host system documentation for more information
on how to configure these settings. The Modbus communication settings can be found by
navigating to
