General requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) - Smart grid - Application specification - Interface and framework for customer - Part 12-1: Interface between the CEM and Home/Building Resource manager - General Requirements and Architecture EN 50491-12-1:2018

Publication date:   Oct 17, 2018

Scope

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).
