DIN EN 50491-11:2016-02

This standard has been prepared as a result of Mandate M/441 issued by the European Commission and in accordance with the functional reference architecture for standardization of functionalities and communication of smart metering for the use of electricity, gas, heat and water applications. Within this scope CLC-TC 205, responsible for Home and Building Electronic Systems, assumes the task of preparing standards for the communication of smart metering systems in the home sector. 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. The document specifies neither the communication mechanisms used on the data interface, nor the applied data privacy and security mechanisms where national regulations may apply. The document does also not specify the communication protocol used between the meters and the meter communication functions. However, existing European Standards such as EN 13757 and the EN 62056 series of standards are used to describe the data model. The responsible committee is DKE/K 716 "Elektrische Systemtechnik für Heim und Gebäude (ESHG)" ("Home and building electronic systems (HBES)") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
