Industrial communication networks. High availability automation networks - Ring-based Redundancy Protocol (RRP) Ingestion-build-264231 • Resistance test to corrosion1 Scope The IEC 62439 series of standards is applicable to high availability automation networks based on the ISO IEC 88023: 2000 (Ethernet) technology. This part of the IEC 62439 series specifies a redundancy protocol that is based on a ring topology, in which the redundancy protocol is executed at the end nodes, as opposed to being built into the switches. Each node detects link failure and link establishment using media sensing technologies, and
