EN IEC 62056-3-1:2021

Electricity metering data exchange - The DLMS/COSEM suite - Part 3-1: Use of local area networks on twisted pair with carrier signalling

IEC 62056-3-1:2021 is available as IEC 62056-3-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62056-3-1:2021 describes two sets of profiles: the first set of profiles allows a bidirectional communication between a client and a server. This set of profiles is made of three profiles allowing 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 1 This first profile was 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 2 This second profile was published in IEC 62056-31:1999. • 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 and in IEC 62056 6 2 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. The second set of profiles allows unidirectional communication between a given Energy Metering device and a Customer Energy Management System. This second set is made up of three profiles. Subclause 4.2.1 to Clause 8 included specify the bidirectional communication using twisted pair signalling and Clause 9 to 9.5 the unidirectional communication using twisted pair signalling. This second edition cancels and replaces the first edition of IEC 62056-3-1, issued in 2013, and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: • addition of a profile which makes use of the IEC 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.

Échange des données de comptage de l'électricité - La suite DLMS/COSEM - Partie 3-1: Utilisation des réseaux locaux sur paire torsadée avec signal de porteuse

IEC 62056-3-1:2021 est disponible sous forme de IEC 62056-3-1:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. IEC 62056-3-1:2021 décrit deux ensembles de profils: le premier ensemble permet une communication bidirectionnelle entre un client et un serveur. Cet ensemble est composé de trois profils permettant l’échange de données par bus en local avec des stations alimentées ou non en énergie. Pour les stations téléalimentées, le bus fournit l’énergie pour l’échange des données. Trois différents profils sont pris en charge: • Profil de base: ce profil en trois couches fournit des services de télérelevé; NOTE 1 Ce profil a été publié dans l’IEC 61142:1993 et était alors connu sous le nom de Norme Euridis. • Profil avec DLMS: ce profil permet l’utilisation des services DLMS tels qu’ils sont spécifiés dans l’IEC 61334 4 41; NOTE 2 Ce deuxième profil a été publié dans l’IEC 62056-31: 1999. • Profil avec DLMS/COSEM: ce profil permet l’utilisation de la couche Application de DLMS/COSEM et le modèle objet COSEM tels qu’ils sont spécifiés respectivement dans l’IEC 62056 5 3 et dans l’IEC 62056 6 2. Les trois profils utilisent la même couche physique et ils sont entièrement compatibles, c’est-à-dire que des dispositifs mettant en œuvre l’un de ces profils peuvent fonctionner sur le même bus. Le moyen de transmission est la paire torsadée par signal de porteuse et connue sous le nom de Bus Euridis. Le deuxième ensemble de profils permet une communication unidirectionnelle entre un dispositif de comptage de l’énergie (energy metering device) donné et un système de gestion de l’énergie client (customer energy management system). Ce deuxième ensemble est composé de trois profils. Le paragraphe 4.2.1 à l'Article 8 inclus spécifient la communication bidirectionnelle utilisant le signal avec paire torsadée et l'Article 9 au 9.5 spécifient la communication unidirectionnelle utilisant le signal avec paire torsadée. Cette deuxième édition annule et remplace la première édition de l’IEC 62056-3-1, parue en 2013. Cette édition constitue une révision technique. Les principales modifications techniques par rapport à l’édition précédente sont les suivantes: • Ajout d’un profil qui permet l’utilisation de la couche Application et la modélisation objet DLMS/COSEM de l’IEC 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.
