DESCRIPTION

BS EN 62439-4:2010+A1:2012


This standard BS EN 62439-4:2010+A1:2012 Industrial communication networks. High availability automation networks is classified in these ICS categories:
  • 35.100.05 Multilayer applications
  • 35.040.01 Information coding in general
  • 35.040 Character sets and information coding
  • 35.110 Networking
  • 25.040.40 Industrial process measurement and control

The IEC 62439 series is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology.

This part of the IEC 62439 series specifies a redundancy protocol that is based on the duplication of the network, the redundancy protocol being executed within the end nodes, as opposed to a redundancy protocol built in the switches. The switchover decision is taken in each node individually. The cross-network connection capability enables single attached end nodes to be connected on either of the two networks.
