Standalone Architectures

Introduction

This topic describes the use of the BMENOR2200H module in a standalone M580 system.

Connection Media

Make connections to the BMENOR2200H module with a cable or a wireless medium:

upstream connection: Connect the module to a SCADA system through the DNP3 protocol. (A Modbus TCP connection is another option.)
downstream connection: Connect the module to remote outstation devices and stations through the DNP3 protocol.

Limitations

Observe these guidelines when you use the BMENOR2200H module:

The module is compatible with Control Expert 14.1 Hot Fix and later.
The module is compatible with CPUs that run firmware version 2.2 or later.
The module does not support Hot Standby systems in Control Expert 14.1 or earlier versions.

Hot Standby

A Hot Standby system uses a primary PAC (PLC) and a standby PAC. The two PAC racks have identical hardware and software configurations. The standby PAC monitors the current system status of the primary PAC. If the primary PAC becomes inoperable, high-availability control is maintained when the standby PAC takes control of the system.
