Electricity metering data exchange - The DLMS/COSEM suite - Part 6-2: COSEM interface classes (IEC 62056-6-2:2013)

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.

Echange de données pour le comptage de l'énergie électrique - La suite DLMS/COSEM - Partie 6-2: Classes d'interfaces COSEM (CEI 62056-6-2:2013)

La CEI 62056-6-2:2013 spécifie un modèle d'un 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.

Izmenjava podatkov meritev električne energije - Niz DLMS/COSEM - 6-2. del: Vmesniški razredi COSEM (IEC 62056-6-2:2013)

Ta del standarda IEC 62056 določa model števca, kot je videti prek komunikacijskega vmesnika. Splošni gradniki so določeni z metodami, ki so usmerjene v predmete, in sicer v obliki razredov vmesnikov za modele števcev od preprostih do zapletenih funkcij.
