Industrial communication networks. High availability automation networks - Cross-network Redundancy Protocol (CRP) Ingestion-build-78747 • Category 1 is applicable1 Scope The IEC 62439 series is applicable to high availability automation networks based on the ISO IEC 88023 (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
