Industrial communication networks - High availability automation networks - Part 3: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)
IEC 62439-3:2012 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: duplication of the LAN, resp. duplication of the transmitted information. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. The main changes with respect to the previous edition are: - specification of the interconnection of PRP and HSR networks; - introduction of a suffix for PRP frames; - clarification and modification of specifications to ensure interoperability; - slackening of the specifications to allow different implementations; - consideration of clock synchronization according to IEC 61588; - introduction of test modes to simplify testing and maintenance.

Réseaux industriels de communication - Réseaux d’automatisme à haute disponibilité - Partie 3 : Protocole de redondance parallèle (PRP) et redondance transparente de haute disponibilité (HSR)
La CEI 62439-3:2012 spécifie deux protocoles de redondance conçus pour assurer une reprise transparente en cas de défaillance unique d'une maille inter-étage ou d'un pont au sein du réseau, qui reposent sur le même schéma: duplication du réseau local, duplication des informations transmises. Cette deuxième édition annule et remplace la première édition parue en 2010. Elle constitue une révision technique. Les principales modifications apportées à l'édition précédente sont: - spécification de l'interconnexion des réseaux PRP et HSR; - introduction d'un suffixe pour les trames PRP; - clarification et modification des spécifications pour garantir l'interopérabilité; - assouplissement des spécifications pour permettre des mises en oeuvre différentes; - prise en compte de la synchronisation des horloges conformément à la CEI 61588; - introduction de modes d'essai visant à simplifier les essais et la maintenance.
Industrijska komunikacijska omrežja za avtomatizacijo z visoko razpoložljivostjo - 3. del: Protokol vzporedne redundance (RPR) in brezprehodna zanka z visoko razpoložljivostjo (IEC 62439-3:2012)
Serija IEC 62439 se uporablja za avtomatizacijska omrežja z veliko razpoložljivostjo, ki temeljijo na tehnologiji iz standarda ISO/IEC 8802-3 (Ethernet). Ta del standarda IEC 62439 določa dva protokola redundance, zasnovana za zagotavljanje hitre obnovitve v primeru izpada ene medmostne povezave ali mostu v omrežju, ki temelji na isti shemi: podvojevanje LAN oziroma podvojevanje oddajanih informacij.
