(Main)Industrial communication networks - High availability automation networks - Part 2: Media Redundancy Protocol (MRP)
Industrial communication networks - High availability automation networks - Part 2: Media Redundancy Protocol (MRP)
IEC 62439-2:2021 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE Std 802.3) (Ethernet) technology. The IEC 62439-2:2021 specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node.

Réseaux de communication industriels – Réseaux de haute disponibilité pour l'automatisation – Partie 2: Protocole de redondance du support (MRP)
IEC 62439-2:2021 s'applique aux réseaux de haute disponibilité pour l'automatisation qui reposent sur la technologie ISO/IEC/IEEE 8802-3 (IEEE Std 802.3) (Ethernet). L'IEC 62439-2:2021 spécifie un protocole de reprise reposant sur une topologie en anneau, qui est conçu pour réagir de manière déterministe en cas de défaillance unique sur une maille interétage ou sur un commutateur du réseau, sous le contrôle d'un nœud du gestionnaire de redondance du support dédié.
Industrijska komunikacijska omrežja - Omrežja za avtomatizacijo z visoko razpoložljivostjo - 2. del: Protokol z redundanco medijev (MRP) (IEC 62439-2:2021)
Standardi iz skupine IEC 62439 se uporabljajo za avtomatizacijska omrežja z visoko razpoložljivostjo, ki temeljijo na tehnologiji iz standarda ISO/IEC/IEEE 8802-3 (IEEE 802.3) (Ethernet).
Ta del skupine standardov IEC 62439 določa obnovitveni protokol, ki temelji na obročni topologiji, ki je zasnovana za determinističen odziv pri posamezni okvari povezave med stikali ali stikali v omrežju pod nadzorom dodeljenega vozlišča upravitelja redundance medijev.
