AMENDMENT 1 Industrial communication networks – High availability automation networks – Part 4: Cross-network Redundancy Protocol (CRP)

ICS Code (Information coding): | 35.040 |

scope:
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.
