Heat meters - Part 3: Data exchange and interfaces
This European Standard specifies the general requirements and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The meter indicates heat in legal units.
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.

Der Wärmezähler zeigt die Wärme in gesetzlichen Einheiten an.
Teil 3 legt den Datenaustausch zwischen einem Zähler und einem Auslesegerät fest (PUNKT / PUNKT Kommunikation). Für diese Anwendungen, die einen optischen Auslesekopf verwenden, wird das Protokoll nach EN 62056-21 empfohlen.
Für direkte oder örtliche Fernauslesung eines einzelnen oder mehrerer Zähler über ein batteriebetriebenes Auslesegerät wird die Bitübertragungsschicht nach EN 13757-6 (lokales Bussystem) empfohlen.
Für größere Netzwerke mit bis zu 250 m ist eine Master-Einheit mit Wechselstromversorgung nach EN 13757-2 erforderlich, um den M Bus zu steuern. Für diese Anwendungen ist die Bitübertragungs- und Sicherungsschicht nach EN 13757-2 und die Anwendungsschicht nach EN 13757-3 erforderlich.
Für Zählerkommunikation über Funk beschreibt EN 13757-4 mehrere Alternativen des mobilen Auslesens oder durch Verwendung eines ortsfesten Empfängers oder eines Netzwerkes. Sowohl Zähler mit unidirektionaler als auch bidirektional Übertragung werden durch diese Norm abgedeckt.

Recommendation for heat meter test interface Modern heat meters are mainly equipped with CMOS microprocessors with a very low power consumption, allowing battery operation. Testing and adjusting of this type of meters needs a completely different approach. Until now, almost every meter type needed its own test equipment to handle the manufacturer's specific requirements. This is a very complicated and expensive way for users of several types of meters and for initial verification institutes. The more different types of heat meters a user has installed, the more testing equipment he may need. An economical testing of several meters should be possible and an easy adaptation to the existing test bench is of great interest. Since this problem came up, experts have been researching an acceptable solution to it. Details of one example of an acceptable solution are given in AGFW FW 203, "Normierter Wärmezähler-Adapter" [3]. SIST EN 1434-3:2016

La norme SIST EN 1434-3:2016 présente des exigences générales pour les compteurs de chaleur, des instruments essentiels pour mesurer l'énergie dans un circuit d'échange thermique. Son champ d'application est significatif, traitant spécifiquement des méthodes de mesure de la chaleur, tant pour le refroidissement que pour le chauffage, en utilisant un fluide de transfert thermique. Cette précision dans la définition de la norme assure que les compteurs de chaleur peuvent fournir des indications dans des unités légales acceptées. Un des points forts de cette norme est sa spécification sur l'échange de données entre le compteur et un appareil de lecture, utilisant la communication POINT / POINT. Cela est particulièrement pertinent dans un contexte où la gestion des données et l'accessibilité de l'information sont devenues cruciales. La recommandation d'utiliser le protocole EN 62056-21 pour les applications nécessitant une tête de lecture optique démontre l'engagement de la norme vers l'interopérabilité et l'efficacité des processus de lecture. Concernant la lecture directe ou à distance de compteurs, la norme propose des solutions variées, selon le nombre de compteurs à gérer. L'utilisation d'un dispositif de lecture par batterie pour un nombre limité de compteurs et la nécessité d'une unité maître alimentée par le réseau électrique pour des réseaux plus larges illustrent la flexibilité de la norme. En intégrant les couches physiques et de liaison des normes EN 13757-2 et EN 13757-3, cette norme garantit une communication efficace dans des configurations complexes. De plus, la prise en charge des communications sans fil, ainsi que l'option d'un fonctionnement unidirectionnel et bidirectionnel des compteurs, accorde à la norme une grande pertinence dans le développement technologique actuel. Les alternatives pour la lecture de compteurs via des stations mobiles ou des récepteurs stationnaires augmentent l'accessibilité et l'efficacité, répondant aux besoins croissants de collecte de données dans les systèmes de gestion de l'énergie. En somme, la norme SIST EN 1434-3:2016 se positionne comme un standard essentiel pour les compteurs de chaleur, offrant des directives claires et des recommandations qui facilitent l'intégration et l'utilisation efficace de ces instruments dans des systèmes modernes de mesure. Sa portée, ainsi que ses atouts en matière de communication et d'interopérabilité, en font un document fondamental pour les professionnels du secteur.
The SIST EN 1434-3:2016 standard outlines critical requirements for heat meters, focusing on data exchange and interfaces, thereby addressing essential aspects of energy measurement in heating and cooling systems. This standard is pertinent for professionals in the energy metering industry, as it ensures that heat meters effectively track the energy consumed or released in heat-exchange circuits. One of the significant strengths of this standard is its comprehensive coverage of the various communication protocols necessary for effective data exchange between meters and readout devices. By recommending the EN 62056-21 protocol for optical readout heads, it ensures compatibility and reliability in data transmission. Furthermore, the guidance for local readout via battery-driven devices through EN 13757-6 demonstrates the standard's adaptability to different operational needs. The structured approach to larger network setups is another merit of the SIST EN 1434-3:2016 standard. It specifies the necessity of a master unit for controlling up to 250 meters through M-Bus according to EN 13757-2. This scalability illustrates the standard's relevance in both small-scale and larger installations, promoting efficiency and effectiveness in energy management systems. Additionally, the inclusion of various methods for wireless meter communications as described in EN 13757-4 enhances the standard's applicability. By supporting both unidirectional and bidirectional data transmission, the standard accommodates a wide range of operational scenarios, thereby increasing its utility for different stakeholders in the heat metering sector. In conclusion, the SIST EN 1434-3:2016 standard is essential for ensuring accurate data exchange and interface compatibility in heat meters, providing a robust framework for energy measurement that supports both current and emerging technologies in the field. Its focus on standardization enhances the reliability and interoperability of heat meters, which is crucial for efficient energy management solutions.
SIST EN 1434-3:2016 표준은 열계측기와 관련된 데이터 교환 및 인터페이스에 대한 일반 요구사항을 규정하고 있습니다. 이 표준은 열교환 회로에서 열을 흡수하거나 방출하는 액체인 열 전달 액체를 통해 에너지를 측정하는 데 사용되는 열계측기에 적용됩니다. 특히, 이 표준은 법적 단위로 열을 표시하는 기기에 대한 요구사항을 다루고 있습니다. 이 표준의 강점 중 하나는 열계측기와 판독 장치 간의 데이터 교환을 위한 다양한 통신 방법을 제공한다는 점입니다. 예를 들어, 광학 판독 장치를 사용하는 경우 EN 62056-21 프로토콜을 추천하고 있으며, 배터리 구동의 판독 장치를 통해 단일 또는 소수의 미터를 직접 또는 원격으로 판독할 수 있는 방법에 대해서는 EN 13757-6 (로컬 버스)의 물리적 계층을 권장합니다. 이러한 다양한 접근 방식은 사용자의 필요에 맞는 유연성을 제공합니다. 또한, 최대 250개의 미터를 포함하는 대규모 네트워크에 대한 요구사항도 명시되어 있습니다. 이를 위해서는 EN 13757-2에 따른 AC 전원 공급 장치를 가진 마스터 유닛이 필요하며, 이는 M-Bus를 제어하는 데 필수적입니다. 이와 함께 EN 13757-2의 물리적 및 링크 계층과 EN 13757-3의 응용 계층이 요구됩니다. 무선 계량 통신에 대해서도 SIST EN 1434-3:2016 표준은 EN 13757-4를 통해 여러 가지 도보/차량 통과 판독의 대안을 제시하고 있으며, 정방향 통신 및 양방향 통신을 지원하는 미터도 포함되어 있습니다. 이러한 다양한 통신 옵션은 향후 스마트 미터링 시스템에 큰 기여를 할 것으로 예상됩니다. 결론적으로, SIST EN 1434-3:2016 표준은 열계측기와 데이터 교환 간의 기준을 제시하며, 다양한 응용 상황에 적합하도록 설계되어 있어 현대 에너지 관리 시스템에 매우 중요한 문서라고 할 수 있습니다.
