Annotation of standard text IEC 62439-3-ed.4.0 :

IEC 62439-3:2021 specifies two related redundancy protocols that, in the event of failure of any network element, provide seamless switchover with zero recovery time: • PRP (Parallel Redundancy Protocol), which allows attaching nodes to two separate networks while allowing attachment of nodes to one network only; and • HSR (High-availability Seamless Redundancy), which allows threading two-port nodes in a ring or multi-port nodes in a meshed network. The contents of the corrigendum of April 2023 have been included in this copy. IEC 62469-3:2021 specifie deux protocoles de redondance associes qui assurent une commutation transparente avec un temps de reprise nul en cas de defaillance dun element de reseau: • le protocole de redondance en parallele PRP (Parallel Redundancy Protocol) qui permet dassocier des nouds a deux reseaux tout en permettant dassocier des nouds a un seul reseau; et • la redondance transparente de haute disponibilite HSR (High-availability Seamless Redundancy) qui permet de lier des nouds a deux ports dans un anneau ou des nouds a plusieurs ports dans un reseau maille. Le contenu du corrigendum davril 2023 a ete pris en consideration dans cet exemplaire.
