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

IEC 62056-6-2:2017 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. This third edition cancels and replaces the second edition of IEC 62056-6-2 published in 2016. It constitutes a technical revision. The significant technical changes with respect to the previous edition are listed in Annex F(Informative).

Datenkommunikation der elektrischen Energiemessung - DLMS/COSEM - Teil 6-2: Interface-Klassen

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

L'IEC 62056-6-2:2017 spécifie un modèle de compteur tel qu'il est vu à travers son/ses interface(s) de communication. Des blocs génériques de base sont définis à l'aide de méthodes orientées objet, sous la forme de classes d'interfaces pour modéliser les compteurs à partir d'une fonctionnalité simple jusqu'à une fonctionnalité très complexe. L'Annexe A à l'Annexe F (informative) donnent des informations supplémentaires relatives à certaines classes d'interfaces. Cette troisième édition annule et remplace la deuxième édition de l'IEC 62056-6-2, parue en 2016. 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

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.
