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

EN-IEC 62056 describes three profiles for local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported: - base profile: this three-layer profile provides remote communication services; NOTE This first profile has been published in IEC 61142:1993 and became known as the Euridis standard. - profile with DLMS: this profile allows using DLMS services as specified in IEC 61334-4-41; NOTE This second profile has been published in IEC 62056-31 Ed. 1.0:1999; - profile with DLMS/COSEM: this profile allows using the DLMS/COSEM Application layer and the COSEM object model as specified in IEC 62056-5-3 Ed. 1.0:- and in IEC 62056- 6-2 Ed. 1.0:- respectively. The three profiles use the same physical layer and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signalling and it is known as the Euridis Bus.

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

La CEI 62056-3-1:2013 décrit trois profils pour échange de données par bus en local avec des stations alimentées ou non en énergie. Pour les stations télé-alimentées, le bus fournit l'énergie pour l'échange des données. Trois différents profils sont supportés:
- Profil de base;
- Profil avec DLMS;
- Profil avec DLMS/COSEM. Les trois profils utilisent la même couche physique et ils sont entièrement compatibles, c'est-à-dire que des équipements ayant implémenté l'un de ces profils peuvent opérer sur le même bus. Le moyen de transmission est la paire torsadée par signal de porteuse et connue sous le nom de Bus Euridis. Cette première édition annule et remplace la première édition de la CEI 62056-31, parue en 1999, dont elle constitue une révision technique. Les modifications techniques sont:
- Ajout d'un profil qui permet l'utilisation de la couche Application et la modélisation objet DLMS/COSEM de la CEI 62056,
- Révision de la couche liaison de données qui est maintenant scindée en deux parties: la première est intégralement une couche de liaison de données; la dernière, nommée "Gestion du Support", gère le média de communication;
- Capacité de négocier la vitesse de communication, portant la vitesse maximale jusqu'à 9 600 bauds.

Merjenje električne energije - Izmenjevanje podatkov za odbiranje stanja števcev, tarife in krmiljenje obremenitve - 31. del: Uporaba lokalnih omrežij prek zvitih parov s signalizacijo po nosilcu (IEC 62056-3-1:2013)

Standard EN-IEC 62056 opisuje tri profile izmenjave podatkov prek lokalnega vodila s postajo z napajanjem ali brez. Pri postajah brez napajanja vodilo zagotavlja energijo za izmenjavo podatkov. Podprti so trije različni profili: – osnovni profil: ta triplastni profil omogoča oddaljene komunikacijske storitve; OPOMBA Ta profil je bil objavljen v standardu IEC 61142:1993 in je poznan kot standard Euridis. – profil z DLMS: ta profil omogoča uporabo storitev DLMS iz standarda IEC 61334-4-41; OPOMBA Ta profil je bil objavljen v standardu IEC 62056-31, izdaja 1.0:1999; – profil z DLMS/COSEM: ta profil omogoča uporabo aplikacijske plasti DLMS/COSEM in objektnega modula COSEM iz standarda IEC 62056-5-3, izdaja 1.0:– in iz standarda IEC 62056- 6-2, izdaja 1.0. Ti trije profili uporabljajo enako fizično plast in so popolnoma združljivi, kar pomeni, da naprave v skladu s katerim koli od teh profilov lahko delujejo na istem vodilu. Medij prenosa je zvit par s signalizacijo po nosilcu in je poznan kot vodilo Euridis.

This European Standard was approved by CENELEC on 2013-09-24. CENELEC 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.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the CEN-CENELEC Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the CEN-CENELEC Management Centre has the same status as the official versions.

Foreword
The text of document 13/1546/FDIS, future edition 1 of IEC 62056-3-1, prepared by IEC/TC 13
"Electrical energy measurement, tariff- and load control" was submitted to the IEC-CENELEC parallel
vote and approved by CENELEC as EN 62056-3-1:2014.

The following dates are fixed:
(dop) 2014-09-07
• latest date by which the document has to be
implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2016-09-24
standards conflicting with the
document have to be withdrawn

This document supersedes EN 62056-31:2000.

EN 62056-3-1:2014 includes the following significant technical changes with respect to
EN 62056-31:2000:
• addition of a profile which makes use of the EN 62056 DLMS/COSEM Application layer and
COSEM object model;
• review of the data link layer which is split into two parts:
– a pure Data Link layer;
– a “Support Manager” entity managing the communication media;
• ability to negotiate the communication speed, bringing baud rate up to 9 600 bauds.

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.

Endorsement notice
The text of the International Standard IEC 62056-3-1:2013 was approved by CENELEC as a
European Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:

IEC 62056-6-1:2013 NOTE Harmonized as EN 62056-6-1:2013 (not modified).
