I have a DNP 3.0 RTU Slave and on other hand a OMRON PLC that speak Fins command through its Ethernet port. I want to install a server computer running a OPC server performing as a bridge for both devices (RTU and PLC) to allow PLC take the data it needs from RTU database for the process.

The protocols above mentioned are the optimum for the design, but another protocols are posible. For example the Link Server - RTU could be ModBus and the link PLC - server could be modbus too or Host Link. I need some idea to solve that problem.

Omron has an OPC Server package. Go to

Best of luck,

You want to convert data between protocol X slave (DNP 3.0 RTU) and protocol Y slave (Omron FINS PLC).

Get the following software.
1. OPC Server for protocol X master (DNP 3.0)
2. OPC Server for protocol Y master (Omron FINS)
3. OPC Gateway to transfer data between [1] and [2].

Why noy use Device Net? The PLC can communicate with Device Net devices directly from a Device Net scanner. Much easier.

I had the same problem any time and solved it using 2 OPC servers: CX OPC server from Omron and IO server (an Australian Product with well behavior). I used the IO server Gateway to pass through items from OMRON PLC by Fins and a DNP 3 RTU.

I could operate a OMRON PLC Out from a RTU input. I don't found the solution slow and I would not use it for critical mission.
