Industrial communication networks - High availability automation networks - Part 4: Cross-network Redundancy Protocol (CRP)
IEC 62439-4:2010(E) is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It 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. It cancels and replaces IEC 62439 published in 2008 and constitutes a technical revision. It includes the following significant technical changes with respect to IEC 62439 (2008): - adding a calculation method for RSTP (rapid spanning tree protocol, IEEE 802.1Q), - adding two new redundancy protocols: HSR (High-availability Seamless Redundancy) and DRP (Distributed Redundancy Protocol), - moving former Clauses 1 to 4 (introduction, definitions, general aspects) and the Annexes (taxonomy, availability calculation) to IEC 62439-1, which serves now as a base for the other documents, - moving Clause 5 (MRP) to IEC 62439-2 with minor editorial changes, - moving Clause 6 (PRP) was to IEC 62439-3 with minor editorial changes, - moving Clause 7 (CRP) was to IEC 62439-4 with minor editorial changes, and - moving Clause 8 (BRP) was to IEC 62439-5 with minor editorial changes, - adding a method to calculate the maximum recovery time of RSTP in a restricted configuration (ring) to IEC 62439-1 as Clause 8, - adding specifications of the HSR (High-availability Seamless Redundancy) protocol, which shares the principles of PRP to IEC 62439-3 as Clause 5, and - introducing the DRP protocol as IEC 62439-6.

La CEI 62439-4:2010 est applicable aux réseaux d'automatisation à haute disponibilité basés sur la technologie ISO/CEI 8802-3 (IEEE 802.3) (Ethernet). Elle définit un protocole de redondance basé sur la duplication du réseau, le protocole de redondance étant exécuté dans les n uds terminaux, par opposition à un protocole de redondance intégré aux commutateurs. La décision de commutation est prise individuellement par chaque n ud. La capacité de connexion inter-réseau permet à des n uds terminaux simples d'être connectés à l'un ou l'autre des deux réseaux. Elle annule et remplace la CEI 62439 publiée en 2008. et constitue une révision technique. Elle inclut les modifications techniques majeures suivantes par rapport à la CEI 62439 (2008): - ajout d'une méthode de calcul pour les RSTP (Rapid spanning tree protocol, IEEE 802.1Q), - ajout de deux nouveaux protocoles de redondance: HSR (High-availability Seamless Redundancy) et DRP (Distributed Redundancy Protocol), - transfert des anciens Articles 1 à 4 (introduction, définitions, aspects généraux) et des Annexes (taxonomie, calcul de disponibilité) dans la CEI 62439-1, qui sert désormais de base pour les autres documents, - transfert de l'Article 5 (MRP) dans la CEI 62439-2 avec des modifications éditoriales mineures, - transfert de l'Article 6 (PRP) dans la CEI 62439-3 avec des modifications éditoriales mineures, - transfert de l'Article 7 (CRP) dans la CEI 62439-4 avec des modifications éditoriales mineures, et - transfert de l'Article 8 (BRP) dans la CEI 62439-5 avec des modifications éditoriales mineures, - ajout d'une méthode de calcul de la durée maximale de rétablissement de RSTP dans une configuration réduite (anneau) dans la CEI 62439-1 comme Article 8, - ajout de spécifications de protocole HSR (High-availability Seamless Redundancy), qui partage les principes de PRP dans la CEI 62439-3 comme Article 5, et - introduction du protocole DRP en tant que CEI 62439-6. Cette publication doit être lue conjointement avec la CEI 62439-1:2010.
Industrijska komunikacijska omrežja za avtomatizacijo z visoko razpoložljivostjo - 4. del: Protokol redundance prepletenega omrežja (CRP) (CRP) (IEC 62439-4:2010)
Serija IEC 62439 velja za omrežja za avtomatizacijo z visoko razpoložljivostjo, osnovana na ISO/IEC 8802-3 (IEEE 802.3) (eternet) tehnologiji. Ta del serije IEC 62439 določa redundančni protokol, osnovan na podvajanju omrežja, kjer se redundančni protokol izvaja znotraj končnih vozlišč, v nasprotju z redundančnimi protokoli vgrajenimi v stikala. Odločitev za preklop se izvede na vsakem vozlišču posebej. Med-mrežna sposobnost povezave omogoča enojnim priključenim končnim vozliščem, da so lahko povezana na obeh omrežjih.
