EN 50491-11:2015

General requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) - Part 11: Smart Metering - Application Specifications - Simple External Consumer Display

This European Standard specifies a data model to abstract the metering world towards a simple external consumer display. The data model, as described by means of functional blocks contained in this European Standard, lays down the format of metering data accessible by a simple external consumer display. This data interface would be typically part of the meter communication functions and be accessed by a simple external consumer display via the H1 interface of the CEN/CLC/ETSI TR 50572 between the display and the meter communication functions. The data interface specified in this document may also be accessed by the LNAP or NNAP through the C or M interface, after which the data could be accessed by HBES devices through the H2 and H3 interface. In other words, in this way the same data model can be used both on the H1 as well as the H2 and H3 interface. The document specifies neither the communication mechanisms used on the data interface, nor the applied data privacy and security mechanisms nor the ergonomics of the simple external consumer displays, where national regulations may apply. The document does also not specify the communication protocol used between the meters and the meter communication functions. However, it takes into account the existing European standards like the EN 13757 series (in particular EN 13757-3:2013 and its Annex O) and the EN 62056 series for the definition of the data model.

Allgemeine Anforderungen an die Elektrische Systemtechnik für Heim und Gebäude (ESHG) und an Systeme der Gebäudeautomation (GA) - Teil 11: Smart Metering - Applikationsbeschreibung - Einfache externe Verbrauchsanzeige

Diese Europäische Norm spezifiziert ein Datenmodell zur Abstraktion des Bereichs Verbrauchszählung (en: metering) hinsichtlich einer einfachen externen Verbrauchsanzeige. Das Datenmodell, wie es mittels Funktionsblöcken beschrieben wird, welche in dieser Europäischen Norm enthalten sind, legt ein Format für Mess- und Verbrauchswerte fest, die für eine einfache externe Verbrauchsanzeige verfügbar sind. Diese Datenschnittstelle ist üblicherweise Teil der Kommunikationsfunktionen des Zählers (en: meter). Eine einfache externe Verbrauchsanzeige kann über die H1-Schnittstelle nach TR 50572 auf die Kommunikationsfunktionen des Zählers zugreifen. Auf die in diesem Dokument spezifizierte Datenschnittstelle kann auch durch das LNAP oder NNAP über die C- oder M-Schnittstelle zugegriffen werden, worauf folgend durch ESHG-Geräte über die H2- oder H3-Schnittstelle auf die Daten zugegriffen werden kann. Mit anderen Worten können die Daten auf diese Weise sowohl in der H1- als auch in der H2- und H3-Schnittstelle verwendet werden. Das vorliegende Dokument spezifiziert weder die an der Datenschnittstelle verwendeten Kommunikations-mechanismen noch die angewendeten Datenschutz- und Datensicherheitsmechanismen, wo nationale Vorschriften gelten können. Das vorliegende Dokument legt auch nicht das Kommunikationsprotokoll fest, das zwischen Zähler und den Kommunikationsfunktionen der Zähler eingesetzt wird. Für die Beschreibung des Datenmodells werden jedoch die bestehenden Europäischen Normen wie EN 13757 und die Reihe der Normen EN 62056 herangezogen.

Splošne zahteve za stanovanjske in stavbne elektronske sisteme (HBES) in sisteme za avtomatizacijo in krmiljenje stavb (BACS) - 11. del: Inteligentno merjenje - Aplikacijske specifikacije - Preprost zunanji prikazovalnik za uporabnika

Ta evropski standard določa podatkovni model za prenos podatkov merilnikov na preprost zunanji prikazovalnik za uporabnika. Podatkovni model, kot je opisan na podlagi funkcionalnih blokov, zajetih v tem evropskem standardu, določa obliko meritvenih podatkov, ki so dostopni prek preprostega zunanjega prikazovalnika za uporabnika. Ta podatkovni vmesnik je navadno del funkcij za komunikacijo z merilniki in se do njega dostopa s preprostim zunanjim prikazovalnikom za uporabnika prek vmesnika H1 TR 50572 med prikazovalnikom in funkcijami za komunikacijo z merilniki.
Do podatkovnega vmesnika v tem dokumentu se lahko dostopa tudi z LNAP ali NNAP prek vmesnika C ali M, nakar se lahko do podatkov dostopa z napravami HBES prek vmesnikov H2 in H3.
Tako se lahko isti podatkovni model uporablja tako na vmensiku H1 kot na vmesnikih H2 in H3.
Dokument ne določa mehanizmov za komunikacijo, ki se uporabljajo na podatkovnem vmesniku, niti uporabljenih mehanizmov za zasebnost podatkov in varnost, kjer se za te primere uporabljajo nacionalni predpisi.
Prav tako dokument ne določa komunikacijskih protokolov, ki se uporabljajo med merilniki in funkcijami za komunikacijo z merilniki. Kljub temu upošteva obstoječe evropske standarde za opredelitev podatkovnega modela, kot na primer skupine standardov EN 13757 in EN 62056.
