System.

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 Terms, definitions and abbreviations
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
function that uses 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
generally, a specific perspective on a system that contains things with different properties; a
referencing mechanism to organize KIM elements in a specific perspective
EXAMPLE A Function Point is an ex officio Aspect with an important specific perspective. It is a referencing
mechanism to organize together all to a Function Point interoperating Points (all GOs linked to a GA).
3.1.4
BIM
Building Information Model
digital process to describe and document a building in all its life cycle phases, from its planning,
construction, operation up to its demolition
3.1.5
channel
collection of Datapoints of a device that are logically related to each other typically by association with
a hardware feature or a specific function of that device
Note 1 to entry: These Datapoints may be derived from one or more defined Functional Blocks or may be an
expansion above and beyond defined Functional Blocks or may be independent of a Functional Block if none is
defined for the function associated with the Channel. The concept of a Channel is well-understood by the market
participant, e.g. installers.
3.1.6
datapoint
represents a logical input entity of a device acting as recipient of Installation state data, whereas a
logical output of a device acts as source of Installation state data
Note 1 to entry: In case of implementation as a Group Object, state data are communicated with the use of
Function Points.
Note 2 to entry: The term Datapoint is the common term; to specifically denote a Datapoint available on an
IoT 3rd Party API, the term IoT Datapoint is used.
3.1.7
device
physical element that is part of the network; it is a physical, concrete object that a customer can buy
3.1.8
endpoint
entry point to a service, a process, or a queue or topic destination in service-oriented architecture
3.1.9
Feature of Interest
abstraction of a real-world thing (phenomenon, equipment, person, event…) defined by its observable
or actuatable properties
Note 1 to entry: In colloquial terms, a FOI is a property carrier.
Note 2 to entry: A Sensor operates on a FOI with observable properties, an Actuator with actuatable
properties.
Note 3 to entry: A FOI is not a “classification/type” tag itself; the “classification/ type” is accomplished with
the help of tags. Examples are defined in 4.5.1.4.
3.1.10
function
describes a part of the intended behaviour of a FB in a building context
3.1.11
Functional Block
consists of one or more Functions that belong together and that cannot be separated across two
devices but big enough that a device with only one such Functional Block could be marketed
Note 1 to entry: A Functional Block has a well-defined black box behaviour.
3.1.12
Function Point
runtime system state information of a specific Application Function
Note 1 to entry: Shared by at least two Datapoints.
Note 2 to entry: Has a unique identifier that addresses a group of controlled objects. This identifier is called
a Group Address.
EXAMPLE < Light Switch > in living room on/off, whereas the < … > is the Function Point name
3.1.13
Group Address
numerical identifier of a Function Point
3.1.14
Group Communication
communication model in which one sender communicates information to one and typically more
receivers
Note 1 to entry: In IoT, this can be realized by simple UDP communication or by using a message broker
system or other.
3.1.15
Group Object
foreseen for Group Communication using Group Address(es)
Note 1 to entry: May be accessed via point-to-point communication without an assigned Group
Address. With assigned Group Address, it becomes a member of that Function Point represented by
the Group Address.
3.1.16
HBES Information Model
ontology based model of HBES System relevant parts, including additional semantic (dictionary)
information
Note 1 to entry: It is managed by the HBES Association, hence the abbreviation KIM.
3.1.17
Industry Foundation Classes
open standard to describe BIM data in a digital way
Note 1 to entry: IFC data and models are specified in ISO 16739-1.
3.1.18
installation
assembly of materials and components (devices) placed in position to provide a service
Note 1 to entry: An Installation is a deployed system (e.g. HVAC system or fire protection system) and
consists of equipment and Functions that are used for a particular purpose.
Note 2 to entry: In
