This sample standalone network builds upon the single-subnet example and includes BMENOR2200H modules on local racks that communicate with two different
subnets:
Legend:
1BMENOC0321 modules on the local racks connect the RIO main ring and distributed
equipment (DNP3 devices, HMI) to the Ethernet
control network (red).
2 RIO main ring (Dual-ring switches
connect the local rack to two RIO drops and distributed equipment.)
3 A BMENOR2200H module has a direct RS232 connection
to a DNP3 serial device.
4 A BMENOS0300 module on an RIO drop connects distributed equipment (DNP3 devices) to the RIO main ring.
