EN IEC 62056-6-1:2024

Electricity metering data exchange - The DLMS®/COSEM suite - Part 6-1: Object Identification System (OBIS)

This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes. OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of: - logical names of the various instances of the ICs, or objects, as defined in IEC 62056-6-2:2021; - data transmitted through communication lines; - data displayed on the metering equipment, see Clause A.2. This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc. To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately. NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators, thermal energy, gas, cold water and hot water.

Echange des données de comptage de l'électricité - La suite DLMS®/COSEM - Partie 6-1: Système d'identification des objets (OBIS)

IEC 62056-6-1:2023 est disponible sous forme de IEC 62056-6-1:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62056-6-1:2023 spécifie la structure globale du système d’identification des objets (OBIS) et la correspondance entre tous les éléments de données couramment utilisés dans les équipements de comptage et leurs codes d’identification. Le système OBIS fournit un identifiant unique pour toutes les données des équipements de comptage, incluant non seulement les valeurs de mesure, mais aussi les valeurs abstraites utilisées pour la configuration ou pour obtenir des informations sur le comportement des équipements de comptage. Les codes d’identification définis dans le présent document sont utilisés pour identifier: - les noms logiques des différentes instances des classes d’interfaces ou des objets, tels que définis dans l’IEC 62056‑6‑2:2023; - les données transmises par des lignes de communication; - les données affichées sur l’équipement de comptage (voir l'Article A.2 de l’Annexe A). Le présent document s’applique à tous les types d’équipements de comptage, tels que les compteurs entièrement intégrés, les compteurs modulaires, les appareils tarifaires associés aux compteurs, les concentrateurs de données, etc. Les concepts de support et de canaux sont introduits afin de couvrir les équipements de comptage mesurant d’autres types d’énergie que l’électricité, ainsi que les équipements de comptage combinés mesurant plusieurs types d’énergie ou les équipements de comptage avec plusieurs canaux de mesure physiques. Ceci permet d’identifier les données de comptage provenant de différentes sources. Bien que le présent document définisse entièrement la structure du système d’identification pour d’autres supports, la mise en correspondance d’éléments de données associés à une énergie non électrique avec des codes d’identification est effectuée séparément. Cette quatrième édition annule et remplace la troisième édition de l’IEC 62056-6-1 parue en 2017. Cette édition constitue une révision technique. Les modifications techniques majeures par rapport à l’édition précédente sont énumérées dans l’Annexe B (informative).

Izmenjevanje podatkov za odbiranje stanja števcev - Sestav DLMS/COSEM - 6-1. del: Sistem za prepoznavanje objektov (OBIS) (IEC 62056-6-1:2023)

Ta del standarda IEC 62056 določa splošno strukturo sistema za prepoznavanje objektov (OBIS) in preslikave vseh pogosto uporabljanih podatkovnih elementov v opremi za merjenje v njihove identifikacijske oznake.
Sistem za prepoznavanje objektov zagotavlja enolično oznako za vse podatke v opremi za merjenje, vključno z vrednostmi meritev in abstraktnimi vrednostmi, ki se uporabljajo za konfiguracijo ali pridobivanje informacij o delovanju opreme za merjenje. Oznake ID, opredeljene v tem dokumentu, se uporabljajo za prepoznavanje:
• logičnih imen različnih primerkov integriranih vezij ali objektov, kot je opredeljeno v standardu IEC 62056‑6‑2:2023;
• podatkov, prenesenih prek komunikacijskih vodov;
• podatkov, prikazanih prek opreme za merjenje (glej točko A.2 v dodatku A).
Ta dokument se uporablja za vse vrste opreme za merjenje, kot so vgrajeni števci,
modularni števci, tarifni priključki, podatkovni koncentratorji itd.
Za potrebe opreme za merjenje energije, ki ni električna energija, kombinirane opreme za merjenje več kot ene vrste energije ali opreme za merjenje z več fizičnimi merilnimi kanali sta uvedena koncepta medija in kanalov. To omogoča prepoznavanje merilnih podatkov z različnih virov. Čeprav ta dokument v celoti opredeljuje strukturo sistema prepoznavanja za druge medije, se preslikava podatkovnih elementov, povezanih z energijo druge vrste, v oznake ID izvede ločeno.
OPOMBA: Standard EN 13757-1:2014 opredeljuje oznake za opremo za merjenje energije, ki ni električna energija: delilniki stroškov, toplotna energija, plin, hladna in vroča voda.
