Communication systems for meters - Part 1: Data exchange

This document specifies data exchange and communications for meters in a generic way.
This document establishes a protocol specification for the Application Layer for meters and establishes several protocols for meter communications which can be applied depending on the application being fulfilled.
This document also 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.”
NOTE   Electricity meters are not covered by this document, as the standardization of remote readout of electricity meters is a task for CENELEC/IEC.

Kommunikationssysteme für Zähler - Teil 1: Datenaustausch

Dieses Dokument legt den Datenaustausch und die Kommunikation für Zähler in allgemeiner Weise fest.
Es gibt außerdem eine Protokollspezifikation für die Anwendungsschicht für Zähler und verschiedene Protokolle für die Zählerkommunikation an, die in Abhängigkeit von der auszuführenden Anwendung angewendet werden können.
Darüber hinaus wird in diesem Dokument die allgemeine Struktur des Objektidentifikationssystems OBIS und die Zuordnung aller allgemein in Messsystemen verwendeten Datenobjekte zu ihren Identifizierungs-Codes.
ANMERKUNG   Elektrizitätszähler werden von diesem Dokument nicht abgedeckt, da die Normung für die Fernablesung von Elektrizitätszählern CENELEC/IEC obliegt.

Systèmes de communication pour compteurs - Partie 1 : Échange de données

Le présent document explique l’échange de données et les communications relatifs aux compteurs, de manière générale.
Il établit une spécification de protocole pour la couche application des compteurs ainsi que plusieurs protocoles pour les communications des compteurs qui peuvent être appliqués selon l’application en cours de réalisation.
Il précise également la structure générale du système d’identification d’objet (OBIS) et l’organisation des données couramment utilisées dans les équipements de comptage en fonction de leurs codes d’identification.
NOTE   Les compteurs d’énergie électrique ne sont pas concernés par le présent document, car la normalisation du télérelevé des compteurs d’énergie électrique est assurée par le CENELEC/l'IEC.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee

CEN/TC 294.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations

which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
