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.

Wärmezähler - Teil 3: Datenaustausch und Schnittstellen

Diese Europäische Norm legt die allgemeinen Anforderungen für Wärmezähler fest. Wärmezähler sind Geräte, die dazu dienen, die Wärmemenge zu messen, die in einem Wärmetauscherkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit aufgenommen (kühlen) oder abgegeben (heizen) wird. 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.

Compteurs d'énergie thermique - Partie 3 : Échange de données et interfaces

La présente Norme européenne spécifie les exigences générales et s'applique aux compteurs d'énergie thermique. Il s'agit d'instruments prévus pour mesurer l’énergie qui, dans un circuit d’échange d’énergie thermique, est absorbée (refroidissement) ou abandonnée (échauffement) par un liquide appelé liquide transmetteur d'énergie thermique. Le compteur indique l’énergie thermique en unités légales.
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.

Toplotni števci - 3. del: Izmenjava podatkov in vmesniki

Ta evropski standard določa splošne zahteve in se uporablja za toplotne števce. Toplotni števci so instrumenti, namenjeni merjenju energije, ki jo v krogotoku toplotne izmenjave absorbira (hlajenje) ali oddaja (ogrevanje) tekočina, imenovana tekočina za prenos toplote. Števec podaja toploto v predpisanih enotah.
3. del standarda določa izmenjavo podatkov med števcem in napravo za odbiranje (komunikacija tipa TOČKA-TOČKA). Za uporabo z optično glavo za odbiranje se priporoča protokol standarda EN 62056-21.
Za neposredno ali oddaljeno lokalno odbiranje posameznega ali več števcev prek naprave za odbiranje z baterijskim napajanjem se priporoča fizična plast standarda EN 13757-6 (vodilo).
Za večja omrežja do 250 metrov je za nadzor vodila M-Bus potrebna glavna enota z izmeničnim napajanjem v skladu s standardom EN 13757-2. Za te načine uporabe je zahtevana fizična in povezovalna plast glede na standard EN 13757-2 in aplikacijska plast glede na standard EN 13757-3.
Standard EN 13757-4 za brezžične komunikacije števcev opisuje nekatere alternativne možnosti odbiranja med premikanjem po terenu (hoja/vožnja) z mobilno postajo ali prek stacionarnih sprejemnikov ali omrežja. Ta standard podpira števce s komunikacijo v eni ali obeh smereh.

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

이 기사는 EN 1434-3:2015에 대해 다룬다. 이는 열량계에 적용되는 유럽 표준으로, 열전달 액체인 열우동 액체에 의해 흡수(냉각) 또는 방출(가열)되는 열에 대해 측정하는 기기를 말한다. 이 표준은 열량계와 독자 장치 간의 데이터 교환과 인터페이스에 대한 일반적인 요구사항을 명시한다. POINT / POINT 통신을 사용하는 경우, 광학 리드아웃 헤드를 사용하고 EN 62056-21 프로토콜을 추천한다. 단일 또는 일부 열량계의 직접 또는 원격 로컬 리드아웃을 위한 배터리 구동 리드아웃 장치에서는 EN 13757-6(로컬 버스)의 물리 계층을 추천한다. 최대 250개의 열량계를 갖는 대형 네트워크의 경우, EN 13757-2에 따른 AC 전원 공급을 갖는 마스터 유닛이 M-Bus를 제어하기 위해 필요하다. 이러한 응용에는 EN 13757-2의 물리 및 링크 계층과 EN 13757-3의 응용 계층이 필요하다. 무선 열량계 통신의 경우, 이 표준은 이동 기반의 리드아웃, 고정 수신기 또는 네트워크를 사용하여 줄/타고다니는 리드아웃의 여러 가지 대안을 설명한다. 이 표준은 단방향과 양방향으로 전송되는 열량계를 모두 지원한다.

この記事はEN 1434-3:2015について述べています。これは熱量計に適用されるヨーロッパの標準であり、熱交換回路内の熱伝達液体によって吸収（冷却）または放出（加熱）されるエネルギーを測定するための機器を指します。この標準は、熱量計と読み取り装置間のデータ交換とインタフェースに関する一般的な要件を明示しています。POINT / POINT通信を使用する場合、光学読み取りヘッドを使用し、EN 62056-21プロトコルを推奨しています。バッテリー駆動の読み取り装置による1つまたは複数の熱量計の直接またはリモートローカル読み取りの場合、EN 13757-6（ローカルバス）の物理層が推奨されています。最大250台の熱量計を持つ大規模なネットワークの場合、EN 13757-2に準拠したACメイン電源を備えたマスターユニットがM-Busを制御するために必要です。これらのアプリケーションでは、EN 13757-2の物理層とリンク層、およびEN 13757-3のアプリケーション層が必要です。ワイヤレス熱量メータ通信については、移動基盤による読み取り、固定受信機、またはネットワークを使用した歩行/ドライブバイ読み取りのいくつかの代替手法をEN 13757-4で説明しています。この標準は、単方向および双方向で送信されるメーターの両方をサポートしています。

The article discusses EN 1434-3:2015, a European standard that applies to heat meters. Heat meters are used to measure the energy absorbed or given off by a heat-conveying liquid in a heat-exchange circuit. The standard focuses on data exchange and interfaces between the meter and readout devices. It recommends using the EN 62056-21 protocol for applications with optical readout heads and the physical layer of EN 13757-6 for direct or remote local readout using a battery-driven device. For larger networks with up to 250 meters, an EN 13757-2 compliant master unit with AC mains supply is necessary for controlling the M-Bus. The standard also addresses wireless meter communications, offering alternatives for walk/drive-by readout using mobile stations, stationary receivers, or a network. Both unidirectional and bidirectional transmitting meters are supported.
