Configure Modbus-RTU
Use Modbus-RTU to enable data transmission between devices using the HIPswitch serial interface.
- 
                Connect an RS-232 Modbus Program Logic Controller (PLC) to your HIPswitch
                    using a DB9-to-DB9 or DB9-to-RJ45 cable.
                Note: RS-485 is supported by the HIPswitch-250, but others will require an adapter.
- Go to HIPservices>HIPswitch>Ports>Serial over IP
- 
                Click Edit Settings, and then configure SoIP using the Generic Serial Over
                        IP communications protocol.
                 
 
- 
                Add the SoIP device to an overlay and create policy.
                For information, see Add devices or device groups to an overlay network.
- Using Modbus Polling software, such as FieldTalk's ModPoll, test the configuration using a command such as the following: modpoll -m rtu -r 1 -c 125 -1 -p 4001 10.10.20.162
