CEI EN 50491-12-1 PDF

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).
