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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.

INTRODUCTION
IEC 62264 is a multi-part standard that defines the interface content between enterprise
activities and control activities. This part of IEC 62264 provides the definitions of the
attributes of the object models in IEC 62264-1.
IEC 62264 defines object models of exchanged information between enterprise systems and
control systems. This part of IEC 62264 adds details to the object models through the
definition of attributes, so that implement able interfaces may be constructed. IEC 62264
does not define models of enterprise objects or control objects.
The area of concern of this standard is strongly related to the ISO TC 184 (Industrial
automation systems and integration) scope. Nevertheless the objectives and approaches are
completely different and complementary. Relevant TC184 standards or work in progress
address the modeling of enterprise and/or the modeling of enterprise objects whereas this
standard specifies the content of interfaces between control functions and enterprise
functions. The functions may be precisely modeled with TC184 standards. See
ISO/IEC 62264-1 Annex A for further details.

ENTERPRISE-CONTROL SYSTEM INTEGRATION –

Part 2: Object model attributes

1 Scope
This part of IEC 62264, in conjunction with IEC 62264-1, specifies generic interface content
between manufacturing control functions and other enterprise functions. The interfaces
considered are the interfaces between Levels 3 and 4 of the hierarchical model defined in
IEC 62264-1. The goal is to reduce the risk, cost, and errors associated with implementing
these interfaces.
Since IEC 62264 covers many domains, and there are many different standards in those
domains, the semantics of this Standard are described at a level intended to enable the other
standards to be mapped to these semantics. To this end, this Standard defines a set of
generic interfaces content elements, together with a mechanism for extending those elements
for implementations.
The scope of this part of IEC 62264 is limited to the definition of attributes of the IEC 62264-1
object models.
This part of IEC 62264 does not define attributes to represent the object relationships defined
in IEC 62264-1.
2 Normative references
The following referenced documents are indispensable for the application 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.
IEC 62264-1, Enterprise-Control System Integration – Part 1: Models and terminology
ISO 10303-1:1994, Industrial automation systems and integration – Product data representa-
tion and exchange – Part 1: Overview and fundamental principles
ISO 15704:2000, Industrial automation systems – Requirements for enterprise–reference
architectures and methodologies
3 Terms and definitions
For the purpose of this document, the terms and definitions given in IEC 62264-1 as well as
the following apply.
3.1
event
representation of a solicited or unsolicited fact indicating a state change in the enterprise

62264-2  IEC:2004(E) – 11 –
3.2
product
the desired output or by-product of the processes of an enterprise
NOTE 1 A product may be an intermediate product or end product from a business perspective.
NOTE 2 Also defined in ISO 10303-1 as: ‘a substance produced by a natural or artificial process’.
3.3
property
object denoting an implementation specific characteristic of an entity
4 Object model attributes
4.1 General
This clause describes the attributes associated with the objects listed in IEC 62264-1.
Tables 3 to 88 in Clause 4 define the attributes of objects defined in IEC 62264-1, Clause 7.
The attributes are an extension to the object information model presented in IEC 62264-1 and
are thus a part of the definition of terms. The attributes of this part of IEC 62264 and the
object models of IEC 62264-1 define interface content for integration of Level 3 and Level 4
enterprise-control systems. See also IEC 62264-1, Clause 7.4.
In this part of IEC 62264, the word “Class” used as part of an object definition name is to be
considered as a category, not as a “Class” in the object-oriented sense.
EXAMPLE “Personnel class” is to be considered a “personnel category”, in the sense of distinguishing between the
kinds of personnel in the real world.
A minimum set of industry-independent information has been defined, in this part of
IEC 62264, as attributes. However, values for all attributes may not be required depending on
the actual usage of the models. If additional information, including industry- and application-
specific information, is needed, it shall be represented as property objects. This mechanism is
the extension capability referenced in Clause 1. This solution increases the usability through
the use of standard attributes, and allows flexibility and extensibility through the use of
properties. This was done to make the standard as widely applicable as possible.
4.2 Attribute extensibility
For particular applications, the objects defined in the object models will need to be extended
through the addition of attributes to object class definitions. Accordingly, this part of
IEC 62264 provides for attributes that are application or industry specific, to be modeled in
terms of properties and represented in property classes in the model. For example, the
personnel class property would be used to define application or industry specific attributes for
personnel classes, and person property would be used to contain instance values for the
properties.
4.3 Object model structure
The object models are depicted using the Unified Modelling Language (UML) notational
methodology.
Table 1 defines the UML notations used in the object diagrams.

– 12 – 62264-2 © IEC:2004(E)
Table 1 – UML notation used
Symbol Definition
Defines a package, a collection of object models, state models, use
classes, and other UML models. In this document a package is used to
specify an external model, such as a production rule model, or a reference
Package
to another part of the model.
Defines a class of objects, each with the same types of attributes. Each
object is uniquely identifiable or enumerable. No operations or methods are
Class
listed for the classes. Attributes with a “ – ” before their name indicate
attributes that are generally optional in any use of the class.

An association between elements of a class and elements of another or the
same class. Each association is identified. May have the expected number

or range of members of the subclass, when ‘n’ indicates an indeterminate
number. For example, 0,n means that zero or more members of the
Association name
0.n Role
subclass may exist.

the class is a specialized type of the super class.

Aggregation (made up of) shows that an element of the class is made up of
elements of other classes.

composite object has sole responsibility for disposition of its parts.

4.4 Explanation of tables
4.4.1 Tables of attributes
This subclause gives the meaning of the attribute tables. This includes a listing of the object
identification, data types, and presentation of the examples in the tables.
4.4.2 Object identification
Many objects in the information model require unique identifications (IDs). These IDs shall be
unique within the scope of the exchanged information. This may require translations:
– from the internal ID of the source system to the interface content ID;
– from the interface content ID to the internal ID of the target system.
EXAMPLE A unit may be identified as “X6777” in the interface content, as resource “R100011” in the business
system, and as “East Side Reactor” in the control system.
A unique identification set shall be agreed to in order to exchange information.
The object IDs are used only to identify objects within related exchanged information sets.
The object ID attributes are not global object IDs or database index attributes.

62264-2  IEC:2004(E) – 13 –
Generally, objects that are elements of aggregations, and are not referenced elsewhere in the
model, do not require unique IDs.
4.4.3 Data types
The attributes presented are abstract representations, without any specific data type
specified. A specific implementation will show how the information is represented.
Example 1 An attribute may be represented as a string in one implementation and as a
numeric value in another implementation.
Example 2 A date/time value may be represented in ISO standard format in one
implementation and in Julian calendar format in another.
Example 3 A relationship may be represented by two fields (type and key) in database
tables or by a specific tag in XML.
4.4.4 Presentation of examples
Examples are included with each attribute given. Where multiple examples are used, there
are multiple rows in the right hand column. See Table Table 2 below for how the example
rows and columns are used.
Table 2 – Example table
Attribute name Description Examples
Name of first attribute Description of first attribute Example #1 for first attribute
Example #2 for first attribute
Example #3 for first attribute
Name of second attribute Description of second attribute Example #1 for second attribute
Example #2 for second attribute
Example #3 for second attribute
Name of third attribute Description of third attribute Example #1 for third attribute
Example #2 for third attribute
Example #3 for third attribute

When an example value is a set of values, or a member of a set of values, the set of values is
given within a set of braces, {}.
The examples are purely fictional. They are provided to further describe attributes in the
model. No attempt was made to make the examples complete or representative of any
manufacturing enterprise.
4.4.5 Data relationships
The models used to document a reference to a resource, in another package, using the class
or instance, with additional optional specification using properties, are not fully illustrated in
the IEC 62264-1 object model figures. This relationship does not conform to the Unified
Modeling Language (UML) modeling methodology, but was done to keep the diagrams
simpler. Figure 1 illustrates how it is currently presented, on the left side, and how it could be
more accurately modeled in UML on the right side. UML was used in this standard as a
visualization method and not meant to describe implementations. The simplified relationship
diagram method is used for the following objects and their relationship to another package:
