Sample Network
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:

Legend:
1 A BMENOR2200H module connects the local rack to distributed equipment (DNP3 devices, HMI) via the Ethernet backplane connection using redundant links.
2 BMENOS0300 modules on the local racks connect distributed equipment (DNP3/IEC60870 devices, HMI) to the RIO main rings using redundant links
3 BMENOC0321 modules with IP forwarding enabled connect the RIO main rings and distributed equipment (DNP3/IEC60870 devices, HMI) to the blue network via the service port and the red network through the control network port using redundant links
