Hi Everybody

I need to interlink two RTU which is (i) 200 meters and (ii) 400 meters between two lifting station.

What methodology is best suited and cost effective to interlink the two RTU. The RTU's communicate with each other and the master station we can also control, monitor and viewing alarms.

Also is Modbus/TCP appropriate?

Thanking you in advance.

Hi, ModbusTCP is of course appropiate if your RTUs talk Modbus...

In this scenario, considering the distances, I would suggest to use an ethernet network, considering this:

- If your devices are not TCP-capable, but talk modbus, you could use a Modbus Serial/TCP Converter next to each one.
- For your ethernet network to work properly, you should use switches every 100 meters (Maximum length of Ethernet over CAT5).

Hope this helps!
