This sample standalone network builds upon the
two-subnet example with different (red and green) subnets. In this case, BMENOC0321 modules with embedded IP forwarding in the local racks facilitate the connection to a third (blue) subnet:
1
A BMENOR2200H module
2
A BMENOS0300 module on the local rack connects distributed equipment (DNP3 devices, HMI) to the RIO main ring using redundant links
3
A BMENOC0321 module with IP forwarding enabled connects the RIO main ring and distributed equipment (DNP3 devices, HMI) to the blue network via the service port and the red network through the control network port using redundant links
4
RIO main ring
5
A BMENOS0300 module on an RIO drop connects distributed equipment (DNP3 devices) to the RIO main ring
