EN 62056-31:2000

Electricity metering - Data exchange for meter reading, tariff and load control - Part 31: Use of local area networks on twisted pair with carrier signalling

Describes two new architectures for local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. The first architecture completes the base protocol (EN 61142) with remote transfer services. The second architecture allows operation of DLMS services using the same physical medium and the same physical layer. This complete compatibility guarantees the possibility of using EN 61142 and IEC 62056-31 equipment on the same bus.

Messung der elektrischen Energie - Zählerstandsübertragung, Tarif- und Laststeuerung - Teil 31: Nutzung örtlicher Bereichsnetze mit Trägerfrequenz-Signalübertragung auf verdrillten Zweidrahtleitungen

Comptage de l'électricité - Echange de données pour la lecture des compteurs, le contrôle des tarifs et de la charge - Partie 31: Utilisation des réseaux locaux sur paire torsadée avec signal de porteuse

Décrit deux nouvelles architectures d'échange de données par bus en local avec des stations alimentées ou non en énergie. Pour les stations télé-alimentées, c'est le bus qui fournit l'énergie pour l'échange des données. La première architecture complète le protocole de base (EN 61142) par des services de téléprogrammation simplifiée. La seconde architecture permet de mettre en oeuvre les services DLMS sur le même support physique et avec la même couche physique. Cette totale compatibilité quarantit qu'il est possible d'utiliser des équipements de type EN 61142 et CEI 62056-31 sur le même bus.

Part 31: Use of local area networks on twisted pair

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
International Standard IEC 62056-31 has been prepared by IEC technical committee 13:
Equipment for electrical energy measurement and load control.
This first edition of IEC 62056-31 cancels and replaces the first edition of IEC 61142,
published in 1993, and constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
13/1194/FDIS 13/1203/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is
claimed that compliance with this Internati
