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 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.
