Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 7: CompoNet

IEC 62026-7:2010 specifies an interface system providing bit-level and word-level communication between a controller and control circuit devices such as sensors, actuators, and switching elements. The interface system uses cabling with round or flat profiles containing a two conductor signalling pair and optionally a two conductor power supply pair. This part establishes requirements for the interchangeability of components with such interfaces. This standard cancels and replaces IEC/PAS 62026-7 published in 2009. This first edition constitutes a general technical revision with clarifications only and with no significant change in the technology.

Niederspannungsschaltgeräte - Steuerung-Geräte-Netzwerke (CDIs) - Teil 7: CompoNet

Appareillage à basse tension - Interfaces appareil de commande-appareil (CDI) - Partie 7: CompoNet

La CEI 62026-7:2010 spécifie un système d'interface assurant une communication au niveau bit et au niveau mot entre un appareil de commande et des appareils pour circuit de commande, tels que des capteurs, des actionneurs et des éléments de commutation. Le système d'interface utilise un câblage à profil rond ou plat comportant une paire de signalisation à deux conducteurs et éventuellement une paire d'alimentation à deux conducteurs. Cette partie définit des exigences permettant l'interchangeabilité des composants incluant de telles interfaces. La présente norme annule et remplace la CEI/PAS 62026-7 publiée en 2009. Cette première édition constitue une révision technique générale comportant uniquement des clarifications et aucune modification importante concernant la technologie.

Nizkonapetostne stikalne in krmilne naprave - Krmilni mesniki naprave (CDIs) - 7. del: CompoNet (IEC 62026-7:2010, spremenjen)

Ta del standarda IEC 62026 določa vmesniški sistem, ki zagotavlja komunikacijo na ravni bitov in besed med krmilnikom in krmilnimi napravami, kot so senzorji, aktuatorji in stikalni elementi. Vmesniški sistem uporablja okablenje z okroglimi ali ploščatimi profili, ki vključuje par prevodnikov za signaliziranje in poljubno par prevodnikov za napajanje. Ta del določa zahteve za zamenljivost sestavnih delov s takšnimi vmesniki. Ta del standarda IEC 62026 določa naslednje posebne zahteve za CompoNetTM 1):
– zahteve za vmesnike med krmilnikom in krmilnimi napravami;
– 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.
