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

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.<\/p>\n
