Standalone Network with One Subnet

Sample Network

This sample standalone network includes BMENOR2200H modules on local racks in a single subnet:

Legend:

1 The service port on the CPU connects the RIO main ring and distributed equipment (DNP3 devices, HMI) to the Ethernet control network.

2 RIO main ring (Dual-ring switches connect the local rack to an RIO drop.)

3 A BMENOR2200H module has a RS485 connection to DNP3 serial devices on a daisy chain loop.

4 A BMENOR2200H module has a direct RS232 connection to a DNP3 serial device.

5 A BMENOC0301 module on the local rack connects distributed equipment (DNP3 devices, IEC 60870 devices, HMI) to the RIO main ring.

6 A BMENOS0300 module on an RIO drop connects distributed equipment (DNP3 devices) to the RIO main ring.

NOTE: This example network uses DNP3 devices, but the BMENOR2200H module also supports IEC 60870 devices.
