Sample Network

This M580 architecture implements BMENOR2200H modules in two rack configurations, an M580 redundant system and an M580 Safety redundant system.

Both the redundant system (SYSTEM A) and the Safety redundant system (SYSTEM B) have primary and secondary rack configurations with routing functionality to support redundancy. The connected SCADA network is also equipped with switch routing:

Legend:

1 An M580 redundant PAC connects the main ring to the control network.

2 A BMENOC0301 module connects to the standalone and Safety Hot Standby PACs via the Ethernet backplane that supports distributed equipment.

3 A BMENOR2200H module acts as an RTU server to support DNP3, IEC60870-5-101, or IEC60870-5-104 communications.

4 RIO main ring

5 A dual-ring switch (DRS) connects distributed equipment to the RIO drop on the main ring.

6 Distributed equipment connects to the main ring via the DRS using DNP3, IEC60870-5-101, or IEC60870-5-104 communications.

7 A DIO cloud connects to the main ring via the DRS.

8 BMENOR2200H modules connect to a network splitter block.

9 DNP3 serial devices have RS485 connections to the network splitter block.

NOTE: The primary and standby BMENOR2200H modules use the RIO network or the upstream network to synchronize data. Otherwise, the pair of modules cannot establish Hot Standby functionality.
