Industrial communication networks - High availability automation networks - Part 5: Beacon Redundancy Protocol (BRP)
IEC 62439-5:2016 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE 802.3) Ethernet technology. This part of the IEC 62439 series 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. Fast error detection is provided by two beacon nodes, the switchover decision is taken in every node individually. The cross-network connection capability enables singly attached end nodes to be connected on either of the two networks. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The protocol is now independent of application (Path_Check_Request is sent periodically); - Failure_Notify message has been removed; - Frame format had been changed; - New MAC address had been added. This publication is to be read in conjunction with IEC 62439-1:2010.

IEC 62439-5:2016 concerne les réseaux de haute disponibilité pour l'automation qui reposent sur la technologie Ethernet ISO/IEC/IEEE 8802-3 (IEEE 802.3). La présente partie de la série IEC 62439 porte sur un protocole de redondance qui repose sur la duplication du réseau; ce protocole est exécuté dans les noeuds d'extrémité, par opposition à un protocole de redondance intégré aux commutateurs. La détection rapide des erreurs est assurée par deux noeuds Beacon; la décision de basculement est prise dans chaque noeud individuellement. La capacité de connexion interréseau permet à des noeuds d'extrémité à une seule association d'être connectés sur l'un ou l'autre des deux réseaux. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - le protocole est maintenant indépendant de l'application (Path_Check_Request est périodiquement envoyé); - le message Failure_Notify a été supprimé; - le format de trame a été modifié; - la nouvelle adresse MAC a été ajoutée. Cette publication doit être lue conjointement avec la IEC 62439-1:2010.
Industrijska komunikacijska omrežja - Omrežja za avtomatizacijo z visoko razpoložljivostjo - 5. del: Redundančni protokol radijskega odzivnika (BRP) (IEC 62439-5:2016)
Standard IEC 62439-5:2016 se uporablja za avtomatizacijska omrežja z veliko razpoložljivostjo, ki temeljijo na tehnologiji Ethernet iz standarda ISO/IEC/IEEE 8802-3 (IEEE 802.3). Ta del skupine standardov IEC 62439 določa redundantni protokol, ki temelji na podvajanju omrežja, pri čemer se redundantni protokol izvaja v končnih vozliščih in ni vgrajen v stikala. Hitro zaznavanje napak zagotavljata dve signalni vozlišči, odločitev za preklop pa se sprejme za vsako vozlišče posebej. Sposobnost navzkrižne omrežne povezave omogoča povezavo posamezno pritrjenih končnih vozlišč z enim od obeh omrežij. Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2010. Ta izdaja je tehnično popravljena izdaja. Ta izdaja vključuje naslednje znatne tehnične spremembe glede na prejšnjo izdajo:
– protokol je zdaj neodvisen od aplikacije (zahteva Path_Check_Request se redno pošilja);
– odstranjeno je sporočilo Failure_Notify;
– spremenjena je bila oblika zapisa okvirja;
– dodan je bil nov naslov MAC.
