Language in which you want to receive the document.


This document specifies General Requirements and Architecture of an application layer interface between the Customer Energy Manager (CEM) and Smart Devices (SD) operating within the smart grid premises-side system (i.e. home or building but not industrial premises).
This document does not include requirements for:
– Safety;
– EMC;
– Data security; it is assumed that the underlying protocols will take the data security aspect into account;
NOTE Although data security is not within the scope of this standard, in Clause 4 some high-level design guidelines for data security are provided.
– Special equipment (e.g. legacy heat pumps) with a direct physical connection to the grid, as such equipment bypasses the CEM and is not HBES/BACS enabled (covered by other standards than the EN 50491 series).
