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 standard does not include requirements for:
- safety;
- EMC;
- Data security; it is assumed that the underlying protocols will take the data security aspect into account;
- 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).
