I am thinking of using mgate mb 3180 modbus gateway to connect multilple modbus tcp slaves with multiple rtu masters. Different master will poll different slave. We have only one serial and one ethernet port on the Modbus gateway. How can we connect multiple slaves and rtu masters through same gateway?

Thank you!

 

You can't. Modbus RTU can only have one master per RS-485 bus. You would need to use the 2-port 3280 or the 4-port 3480. Another option would be to use one 3180 per Modbus RTU master.
