INDUSTRIAL SYSTEMS, INSTALLATIONS AND EQUIPMENT AND INDUSTRIAL PRODUCTS –
IDENTIFICATION OF TERMINALS WITHIN A SYSTEM
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national
electrotechnical committees (IEC National Committees). The object of the IEC is to promote international cooperation on all
questions concerning standardization in the electrical and electronic field. To this end and in addition to other activities, the IEC
publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee
interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental
organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreement of the IEC on technical matters, express as nearly as possible an International consensus of
opinion on the relevant subjects since each technical committee has representations from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of standards,
technical reports or guides and they are accepted by the National Committees in that state.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards
transparently to the maximum extent possible in their national or regional standards. Any divergence between the IEC Standard
and the corresponding national or regional standard shall be clearly indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61666 has been prepared by sub-committee 3B: Documentation, of IEC
technical committee No. 3: Documentation and graphical symbols.
The text of this standard is based on the following documents:
FDIS Report on voting
3B/182/FDIS 3B/204/RVD
Full information on the voting for the approval of this standard can be found in the report on voting
indicated in the above table.
Annexes A, B and C are for information only.

IDENTIFICATION OF TERMINALS WITHIN A SYSTEM
1 Scope
This International Standard provides rules for the designation of terminals of objects within a system.
The principles laid down are primarily intended for use in the electrotechnical and related areas, but are
general and applicable to all technical areas. They can be used for systems based on different
technologies or for systems combining several technologies.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute
provisions of this International Standard. At the time of publication, the editions indicated were valid. All
normative documents are subject to revision, and parties to agreements based on this International
Standard are encouraged to investigate the possibility of applying the most recent editions of the
normative documents indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.

3 Definitions
For the purpose of this International Standard, the following definitions apply.
3.1 object: Entity treated in the process of design, engineering, realization, operation, maintenance and
demolition. [IEC 61346-1: 1996, 3.1]
NOTES
1 The entity may refer to an abstract or physical object or to a set of information associated with it.
2 Depending on purpose an object may be viewed in different ways, called aspects.
3.2 system: Set of interrelated objects. [IEC 61346-1: 1996, 3.2]
NOTES
1 Examples of a system: a drive system, a water supply system, a stereo system, a computer.
2 When a system is a part of another system, it may be considered as an object.
3.3 aspect: Specific way of selecting information on or describing a system or an object of a system.
[IEC 61346-1: 1996, 3.3]
NOTE - Such ways may be:
- what the system or object is doing (function viewpoint);
- how the system or object is constructed (product viewpoint);
- where the system or object is located (location viewpoint).
3.4 function: Purpose related to an object. [IEC 61346-1: 1996, 3.4]
3.5 product: Intended or accomplished result of labour or of a natural or artificial process.
[IEC 61346-1: 1996, 3.5]
NOTES
1 A product usually has a part number, order number, type designation, and/or a name.
2 A technical system or plant can be considered as a product.
3.6 reference designation: Identifier of a specific object with respect to the system of which it is a
constituent, based on one or more aspects of that system. [IEC 61346-1: 1996, 3.6]
3.7 terminal: Point of access to an object intended for connection to an external network.
NOTES
1 The connection may refer to:
a) a physical interface between conductors and/or contacts, or piping and/or duct systems to provide a signal, energy or
material flow path;
b) an association of functional nature established between logical elements, software modules, etc. for conveying
information.
2 The external networks may be of different nature and accordingly they may be classified. ISO/IEC 11714-3 provides such
classifications. See also Annex A.
3.8 terminal designation: Identifier of a terminal with respect to the object to which it belongs, related to
one aspect of the object.
3.9 terminal designation set: Set of terminal designations, each identifying the same terminal from
different aspects of the object.

4 Identification of terminals
4.1 General
A number of terminals may be associated with an object. Terminals may be provided for facilitating
connections to different networks, for example connecting to an electrical network, logic function network,
logic network in a software, etc. In order to make possible an unambiguous description of such a network,
each terminal used shall be uniquely identified with respect to the object of interest itself as well as to the
system to which this object belongs.
An identification of a terminal within a system shall be unambiguous. The unambiguous identifier shall
consist of:
- a terminal designation that uniquely identifies the terminal with respect to the object of interest;
preceded by
- a ” : ” (colon); preceded by
- a reference designation that explicitly depicts the object of interest.
Figure1 illustrates the unambiguous identifier of a term
