(Main)Heat Meters - Part 3: Data exchange and interfaces
Heat Meters - Part 3: Data exchange and interfaces
This European Standard applies to heat meters, that is to instruments intended for measuring the heat which, in a heat-exchange circuit, is absorbed or given up by a liquid called the energy-conveying liquid. The meter indicates heat in legal units.
Electrical safety requirements are not covered by this standard.
Part 3 specifies the data exchange between a meter and a readout device (POINT / POINT communication). For these applications using the optical readout head, the EN 62056-21 protocol is recommended.
For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN 13757-6 (local bus) is recommended.
For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN 13757-2 is necessary to control the M-Bus. For these applications the physical and link layer of EN 13757-2 and the application layer of EN 13757-3 is required.
For wireless meter communications, EN 13757-4 describes several alternatives of walk/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.

Compteurs d'énergie thermique - Partie 3 : Echange de données et interfaces
La présente Norme internationale s’applique aux compteurs d’énergie thermique, c’est-à-dire aux instruments prévus pour mesurer l’énergie thermique qui, dans un circuit d’échange d’énergie thermique, est absorbée ou abandonnée par un liquide appelé liquide thermique. Le compteur indique l’énergie thermique en unités légales.
Les exigences en matière de sécurité électrique ne sont pas couvertes par la présente norme.
La Partie 3 spécifie l’échange de données entre un compteur et un dispositif de lecture (communication point à point). Pour les applications qui utilisent une tête de lecture optique, le protocole de l'EN 62056-21 est recommandé.
Pour une lecture directe ou locale à distance d’un seul compteur ou de quelques compteurs par l’intermédiaire d’un dispositif de lecture alimenté par batterie, la couche physique de l’EN 13757-6 (bus local) est recommandée.
Pour les réseaux plus importants comportant jusqu’à 250 compteurs, une unité maître disposant d'une alimentation secteur en courant alternatif conforme à l’EN 13757-2 est nécessaire pour commander le M-bus. Pour ces applications, la couche physique et la couche de liaison de l’EN 13757-2 et la couche d’application de l’EN 13757-3 sont requises.
Pour les communications avec compteurs sans fil, l’EN 13757-4 décrit plusieurs alternatives de lectures à pied/en voiture par l’intermédiaire d’un poste mobile ou en utilisant des récepteurs fixes ou un réseau. Les compteurs à transmission unidirectionnelle et les compteurs à transmission bidirectionnelle sont pris en charge par la présente norme.
