Electricity metering data exchange - The DLMS/COSEM suite - Part 1-0: Smart metering standardization framework

IEC 62056-1-0:2014 provides information on the smart metering use cases and on architectures supported by the IEC 62056 DLMS/COSEM series of standards specifying electricity meter data exchange. It describes the standardization framework including: - the principles on which the standards shall be developed; - the ways the existing standards shall be extended to support new use cases and to accommodate new communication technologies, while maintaining coherency; - the aspects of interoperability and information security. It also provides guidance for selecting the suitable standards for a specific interface within the smart metering system.

L'IEC 62056-1-0:2014 fournit des informations relatives aux cas d'utilisation du comptage intelligent et aux architectures supportées par la série de normes IEC 62056 DLMS/COSEM spécifiant l'échange des données de comptage de l'électricité. Elle décrit le cadre de normalisation incluant: - les principes selon lesquels les normes doivent être développées; - la façon dont les normes existantes doivent être étendues pour couvrir de nouveaux cas d'utilisation et pour accueillir de nouvelles technologies de communication, tout en maintenant la cohérence; - les aspects d'interopérabilité et de sécurité des informations. Elle fournit également des lignes directrices pour la sélection des normes adaptées à une interface spécifique au sein du système de comptage intelligent.

Izmenjava podatkov pri merjenju električne energije - Niz DLMS/COSEM - 1-0. del: Struktura standarda za inteligentno merjenje

Ta del standarda IEC 62056 ponuja informacije o primerih uporabe inteligentnega merjenja in arhitekturah, podprtih z nizom standardov IEC 62056 DLMS/COSEM, ki določajo izmenjavo podatkov pri merjenju električne energije. Opisuje okvira standardizacije, vključno s/z:
• principi, na katerih je treba razviti standarde;
• načini za razširitev obstoječih standardov za podporo novim primerom uporabe in za prilagoditev novim komunikacijskim tehnologijam ob ohranjanju skladnosti;
• vidiki interoperabilnosti in informacijske varnosti.
Ponuja tudi napotke za izbiro primernih standardov za poseben vmesnik v okviru inteligentnega merilnega sistema.
Drugi vidiki merjenja, ki so zajeti v TC13, kot so meroslovne zahteve, preskušanje, varnost in zanesljivost, ne spadajo na področje uporabe tega standarda.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individua
