Industrial communication networks - High availability automation networks - Part 3: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)
IEC 62439-3:2016 is available as IEC 62439-3:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of IEC 62439 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: parallel transmission of duplicated information. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - technical corrections and extension of specifications; - consideration of IEC 61588 clock synchronization with end-to-end delay measurement alongside the existing peer-to-peer delay measurement in PRP.

Réseaux de communication industriels - Réseaux d'automatisme à haute disponibilité - Partie 3 : Protocole de redondance en parallèle (PRP) et redondance transparente de haute disponibilité (HSR)
L'IEC 62439-3:2016 s'applique aux réseaux d'automatisme à haute disponibilité basés sur la technologie Ethernet. Cette partie de l'IEC 62439 spécifie deux protocoles de redondance conçus pour assurer une reprise transparente en cas de défaillance unique de liaison interpont ou de pont au sein du réseau, basés sur le schéma: transmission en parallèle d'informations dupliquées. Cette troisième édition annule et remplace la deuxième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - corrections techniques et extension des spécifications; - prise en compte de la synchronisation des horloges selon l'IEC 61588 lors de la mesure du délai entre extrémités et la mesure existante du délai entre homologues dans le protocole PRP.
Industrijska komunikacijska omrežja za avtomatizacijo z visoko razpoložljivostjo - 3. del: Protokol vzporedne redundance (PRP) in brezprehodna zanka z visoko razpoložljivostjo (HSR) (IEC 62439-3:2016)
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: vzporedno oddajanje podvojenih informacij. Tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2012. Ta izdaja je tehnično popravljena izdaja. Ta izdaja vključuje naslednje pomembne tehnične spremembe glede na prejšnjo izdajo:
– tehnični popravki in razširitev specifikacij;
– upoštevanje sinhronizacije ure, določene v standardu IEC 61588, z meritvami celotnega časovnega zamika in meritvami obstoječega enakovrednega časovnega zamika v PRP.
