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

This part of IEC 62026 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 part of IEC 62026 specifies the following particular requirements for DeviceNet:
− requirements for interfaces between controllers and switching elements;
− normal service conditions for devices;
− constructional and performance requirements;
− tests to verify conformance to requirements.
These particular requirements apply in addition to the general requirements of IEC 62026-1.

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.
