European foreword
This document (EN 50090-6-2:2025) has been prepared by CLC/TC 205 “Home and Building
Electronic Systems (HBES)”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2026-06-30
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2028-06-30
conflicting with this document have to be
withdrawn
This document supersedes EN 50090-6-2:2021 and all of its amendments and corrigenda (if any).
2:2021:
— certain HBES concepts were split to have a better distinction between definitions and their types
(e.g. datapoints and their types);
— improved linking between different concepts such as devices and application functions;
— copies of external ontology parts were removed from the HBES ontology and replaced by
references.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national committee. A
complete listing of these bodies can be found on the CENELEC website.
1 Scope
This document defines the HBES Information Model and a corresponding data exchange format for
the Home and Building HBES Open Communication System.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
applies.

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 50090-1:2011 and the
following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1.1
actuator
point performing an actuation (executed by a specific procedure, with an expected result) that
changes an Installation state during Runtime
Note 1 to entry:
— The term Actuator can be mapped to sosa:Actuator in the SSN Ontology.
— The subject actuation can be mapped to sosa:Actuation in the SSN Ontology.
— The subject procedure can be mapped to sosa:Procedure in the SSN Ontology.
— The subject result can be mapped to sosa:Result in the SSN Ontology.
3.1.2
Application Function
use of a set of Functions to achieve the desired behaviour of a technical system, typically using a
combination of devices exchanging information via their input and output Datapoints
Note 1 to entry: An Application Function may be split into several Functional Blocks with their input and output
Datapoints that are logically connected to each other. The Functional Blocks may be located in one or more
devices.
EXAMPLE Application Functions examples are “direct electrical heating”, “electrical heating with
accumulators”, “warm water heating”, “fan coil air-conditioning” …
Note 2 to entry: The Application Function and Application are meant to be the same. Reason to introduce an
alias term is to use a clear (understandable) reference from Application/ Application Function to the
corresponding KIM class:ApplicationFunction or to the Function in the Management Client.
3.1.3
aspect
