EN 62026-3:2015

Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 3: DeviceNet

IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings: - specification of group 4 messages (5.1.2); - clarifications on messaging protocol (5.2); - addition of I/O multicast poll messages (5.5.2 and 5.5.8); - clarifications on slave behaviour (5.5.4 and 5.5.9); - clarifications on physical layer (transceiver) in 5.7; - miscellaneous corrections/clarifications on cable (8.2); - clarifications on EMC testing (9.2.10) and logical testing (9.3).

Niederspannungsschaltgeräte - Steuerung-Geräte-Netzwerke (CDIs) - Teil 3: DeviceNet

Appareillage à basse tension - Interfaces appareil de commande-appareil (CDI) - Partie 3: DeviceNet

L'IEC 62026-3:2014 spécifie un système d'interfaces entre un ou plusieurs appareils de commande d'une part, et des appareils ou éléments de commutation pour circuits de commande, d'autre part. Le système d'interfaces utilise deux paires conductrices, réunies dans un câble - l'une des paires fournit un support de communication différentiel et l'autre alimente les appareils. Cette partie définit des exigences permettant l'interopérabilité des composants incluant de telles interfaces. Cette troisième édition de l'IEC 62026-3 annule et remplace la deuxième édition parue en 2008. Cette troisième édition constitue une révision technique. Les principales modifications effectuées par rapport à l'édition antérieure sont les suivantes: - spécification des messages du groupe 4 (5.1.2); - clarification du protocole de messagerie (5.2); - ajout de messages d'E/S interrogation multidestinataire (5.5.2 et 5.5.8); - clarifications du comportement esclave (5.5.4 et 5.5.9); - clarifications de la couche physique (transcepteur) en 5.7; - corrections/clarifications diverses relatives au câble (8.2); - clarification des essais de compatibilité électromagnétique (CEM) en 9.2.10 et des essais logiques (9.3).

Nizkonapetostne stikalne in krmilne naprave - Vmesniki krmilne naprave (CDIs) - 3. del: DeviceNet

Ta del standarda IEC 62026 določa vmesniški sistem med enim ali več krmilniki in krmilne naprave ali stikalne elemente. Vmesniški sistem uporablja dva para prevodnikov v enem kablu – eden od teh parov zagotavlja diferencialni komunikacijski medij, drugi par pa zagotavlja napajanje naprav. Ta del določa zahteve za interoperabilnost sestavnih delov s takšnimi vmesniki.
Ta del standarda IEC 62026 določa naslednje posebne zahteve za DeviceNet:
− zahteve za vmesnike med krmilniki in stikalnimi elementi;
− običajne pogoje uporabe za naprave;
− konstrukcijske zahteve in zahteve glede zmogljivosti;
− preskuse za preverjanje skladnosti z zahtevami.
Te posebne zahteve se uporabljajo poleg splošnih zahtev iz standarda IEC 62026-1.
