Electricity metering data exchange - The DLMS®/COSEM suite - Part 6-2: COSEM interface classes

This part of IEC 62056 specifies a model of a meter as it is seen through its communication interface(s). Generic building blocks are defined using object-oriented methods, in the form of interface classes to model meters from simple up to very complex functionality. Annexes A to F (informative) provide additional information related to some interface classes.

Échange des données de comptage de l'électricité - La suite DLMS®/COSEM - Partie 6-2: Classes d'interfaces COSEM

IEC 62056-6-2:2013 spécifie un modèle de compteur tel qu’il est vu à travers son ou ses interfaces de communication. Des blocs génériques de base sont définis à l’aide de méthodes orientées objets, sous forme de classes d’interfaces permettant de modéliser les compteurs ayant des fonctionnalités allant de simples à très complexes. Les Annexes A à F (informatives) donnent des informations supplémentaires relatives à certaines classes d’interfaces. Cette quatrième édition annule et remplace la troisième édition de l’IEC 62056-6-2 parue en 2017. Cette édition constitue une révision technique. Les modifications techniques majeures par rapport à l’édition précédente sont énumérées à l’Annexe F (informative).

Izmenjava podatkov meritev električne energije - Niz DLMS/COSEM - 6-2. del: Vmesniški razredi COSEM (IEC 62056-6-2:2023)

Ta del standarda IEC 62056 določa model števca, kot je videti prek komunikacijskega vmesnika. Splošni gradniki so opredeljeni z metodami, ki so usmerjene v objekte, in sicer v obliki vmesniških razredov za modele števcev od preprostih do zelo zapletenih funkcij.
Dodatki od A do F (informativni) zagotavljajo dodatne informacije v zvezi z nekaterimi vmesniškimi razredi.
