Energy efficiency systems - Simple external consumer display
IEC 63345:2023 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 document, 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 CEN/CLC/ETSI TR 50572 between the display and the meter communication functions.

Systèmes pour l'efficacité énergétique - Affichage simple et externe du client
L'IEC 63345:2023 spécifie un modèle de données pour condenser l'ensemble des données de comptage dans un affichage simple et externe du client. Le modèle de données, décrit au moyen de blocs fonctionnels spécifiés dans le présent document, définit le format des données de comptage accessibles à l'aide d'un affichage simple et externe du client. Cette interface de données fait généralement partie des fonctions de communication du compteur et est accessible à partir d'un affichage simple et externe du client au moyen de l'interface H1 du CEN/CLC/ETSI TR 50572 située entre l'affichage et les fonctions de communication du compteur.
Sistemi energijske učinkovitosti - Preprost zunanji prikazovalnik za uporabnika
Ta dokument 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 dokumentu, 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 CEN/CLC/ETSI 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 vmesniku H1 kot na vmesnikih H2 in H3.
Ta dokument ne določa mehanizmov za komunikacijo, ki se uporabljajo na podatkovnem vmesniku, niti uporabljenih mehanizmov za zasebnost podatkov in varnost ter ergonomije zunanjih prikazovalnikov za uporabnike. Za te primere je mogoče uporabiti nacionalne predpise.
Prav tako dokument ne določa komunikacijskih protokolov, ki se uporabljajo med merilniki in funkcijami za komunikacijo z merilniki. Kljub temu pa upošteva obstoječe standarde, kot sta skupina standardov EN 13757 (zlasti standard EN 13757-3:2018 in njegov dodatek H) ter skupina standardov IEC 62056 za opredelitev podatkovnega modela.
