Overview

EN IEC 62832-2:2020 (IEC 62832-2:2020) defines the model elements of the Digital Factory framework for industrial-process measurement, control and automation. The standard specifies detailed requirements for model components (for example, dictionaries, data elements, libraries and digital assets) and the nature of the information they provide - but it does not prescribe file formats or message encodings. It is part of the IEC 62832 series that supports interoperable Digital Factory and Industry 4.0 implementations.

Key Topics and Technical Requirements

• Model element definitions: Precise definitions for core elements such as ConceptDictionary, ConceptDictionaryEntry, DataElement, CollectionOfDataElements (CDEL), Library, LibraryEntry, DigitalFactory, DFasset, DFassetLink and related identifiers (ElementIdentifier, VersionIdentifier, RoleBasedEquipmentIdentifier).
• DataElementTypes (DET): Formal definitions of specific DataElementTypes and their usage (e.g., DataValue, PhysicalUnit, PreferredName, Description, TimeStamp).
• Permissible values and dictionaries: Rules for permissible values, dictionary entries and how concepts are referenced and reused across models.
• Relationships and associations: Definitions for asset classes, assignments, link endpoints and rules that govern relationships between model elements (DFassetClass, DFassetAssignment, DFassetLinkEndPoint).
• Conventions and UML: Conventions for naming, UML notation and an informative UML model to support implementation and modeling consistency.
• Normative annexes: Includes data type specifications and normative mappings, plus informative annexes for mapping model elements to other data standards and UML diagrams.

Practical Applications and Users

Who benefits:

• Systems integrators and automation engineers building interoperable control and monitoring systems.
• Data architects and digital twin designers who need standardized model element definitions for asset modeling and semantic interoperability.
• Manufacturers and library/catalogue providers creating product/asset information catalogs and reusable component libraries.
• Software vendors developing MES, PLM, SCADA or asset-management solutions requiring standardized data models. Practical uses:
• Creating standardized data dictionaries and asset models (DFasset/DFassetClass) to support configuration, commissioning and lifecycle management.
• Enabling semantic interoperability between engineering tools, ERP/MES and IoT platforms.
• Mapping Digital Factory models to other industry standards for catalogue exchange and identification.

Related Standards (if applicable)

• IEC 62832-1 (Digital factory framework - Part 1: General principles)
• IEC 62832-3 (related parts referenced)
• IEC 61360 series, ISO 13584-42, ISO 22745 (catalogue and dictionary mappings)
• ISO/IEC 6523 (organization identification) and IETF RFC 3986 (URI syntax)

This standard is essential for organizations implementing structured, reusable Digital Factory models and pursuing consistent, standards-based industrial automation and digital twin strategies.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). 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. 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 agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
IEC 62832 provides a framework used for establishing and maintaining the digital
representations of production systems, including the representation of the elements of the
production systems and of the relationships between these elements. The framework is
intended also to support the exchange of information about these elements.
The framework aims at reducing the interoperability barriers for exchange of information for the
various activities related to production systems. The main advantages of this method are that
all information related to a production system is described in a standardized manner, and it can
be used and modified through its entire life cycle. The method defined in IEC 62832 is kept as
generic as possible in order to enable its use in several industrial sectors.
While IEC 62832-1 describes the general principles of the DF reference model together with its
most important model elements, this part of IEC 62832 provides a technology-independent
definition of all model elements of the DF reference model.
The intention of this document is to provide a common base for implementation of the DF
framework using different technologies (for example different dictionary technologies and
different engineering data formats). Proposals for such implementations are provided in
Annex C.
The data type specification provided with this document is intended to allow mapping of the DF
framework to different dictionaries.
Two types of templates for representation, namely for specific DataElementTypes and for model
elements, are described in 3.3. Based on these templates, definitions of specific
DataElementTypes are given in Clause 4, and definitions of model elements, using the
DataElementTypes are given in Clause 5.
To allow broad use of the framework, the requirements for these two sets of definitions are kept
as minimal as possible.
If the concepts of DF framework are applied to provide model elements for different engineering
domains, domain-specific data specifications will be used (for example based on IEC 62656-1).

NOTE 1 The abbreviated term DF is only used as a qualifier for model elements specified in this document. It is not
understood as a replacement for the Digital Factory concept defined in IEC 62832-1:2020, 3.1.19.
NOTE 2 The abbreviated term PS is only used as a qualifier for model elements specified in this document. It is not
understood as a replacement for the production system concept defined in IEC 62832-1:2020, 3.1.24.
3.3 Conventions for representing the definition of a model element
3.3.1 Convention for names
While IEC 62832-1 is using general names for describing the concepts, IEC 62832-2 and
IEC 62832-3 define more formal requirements. In order to clearly identify the names of the
model elements, the documents IEC 62832-2 and IEC 62832-3 use ‘PascalCase’ for names.
A help for matching the names between IEC 62832-1 and IEC 62832-2 is provided in Table B.1
(see Annex B).
3.3.2 Representation of specific DataElementTypes
The template used in this document for representing the definition of specific
DataElementTypes of the DF reference model is specified in Table 1.
NOTE Definitions in this document are independent of actual definitions of model elements in any specific
dictionary.
