IEC EN 62439-5 Industrial Communication Networks - Signal Redundancy Protocol (BRP)

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62439-5 testing. IEC EN 62439-5 applies to high availability automation networks based on ISO/IEC/IEEE 8802-3 (IEEE 802.3) Ethernet technology.

This part of the IEC EN 62439 series specifies a redundancy protocol based on network replication, which is a redundancy protocol executed at end nodes as opposed to a redundancy protocol built into switches. Fast fault detection is provided by two beacon nodes, the pass decision is taken separately at each node. The inter-network connectivity feature allows individually connected end nodes to be connected to one of two networks.

This part of the IEC EN 62439 series specifies a protocol for an Ethernet network tolerant of all single point faults. This protocol is called Beacon Redundancy Protocol or BRP. A BRP-based network is called a BRP network. BRP network is based on switched ISO/IEC/IEEE 8802-3 (IEEE 802.3) (Ethernet) and ISO/IEC/TR 8802-1 (IEEE 802.1) technologies and redundant infrastructure. In this network, the decision to switch between infrastructures is made individually at each end node.

The BRP network topology can be defined as two interconnected upper switches, each driving an underlying topology of star, line, or ring. Beacon end nodes will be connected to the upper switches.
