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.
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.

INTRODUCTION
IEC 62264 is a multi-part standard that defines the interfaces between enterprise activities
and control activities. This standard provides standard models and terminology for describing
the interfaces between the business systems of an entreprise and its manufacturing-control
systems. The models and terminology presented in this standard
a) emphasize good integration practices of control systems with enterprise systems during
the entire life cycle of the systems;
b) can be used to improve existing integration capabilities of manufacturing control systems
with enterprise systems; and
c) can be applied regardless of the degree of automation.
Specifically, this standard provides a standard terminology and a consistent set of concepts
and models for integrating control systems with enterprise systems that will improve
communications between all parties involved. Some of the benefits produced will
a) reduce users' times to reach full production levels for new products;
b) enable vendors to supply appropriate tools for implementing integration of control systems
to enterprise systems;
c) enable users to better identify their needs;
d) reduce the costs of automating manufacturing processes;
e) optimize supply chains; and
f) reduce life-cycle engineering efforts.
It is not the intent of this standard to
− suggest that there is only one way of implementing integration of control systems to
enterprise systems;
− force users to abandon their current methods of handling integration; or
− restrict development in the area of integration of control systems to enterprise systems.
This standard discusses the interface content between manufacturing-control functions and
other enterprise functions, based upon the Purdue Reference Model for CIM (hierarchical
form) as published by ISA. This standard presents a partial model or reference model as
defined in ISO 15704.
The scope of this standard is limited to describing the relevant functions in the enterprise and
the control domain and which objects are normally exchanged between these domains.
Subsequent parts will address how these objects can be exchanged in a robust, secure, and
cost-effective manner preserving the integrity of the complete system.
The intent of Clause 4 is to describe the context of the models in Clause 5 and Clause 6. It
gives the criteria used to determine the scope of the manufacturing control system domain.
Clause 4 does not contain the formal definitions of the models and terminology but describes
the context to understand the other clauses.

62264-1  IEC:2003 – 15 –
The intent of Clause 5 is to describe hierarchy models of the activities involved in
manufacturing-control enterprises. It presents in general terms the activities that are
associated with manufacturing control and the activities that occur at the business logistics
level. It also gives an equipment hierarchy model of equipment associated with manufacturing
control.
The intent of Clause 6 is to describe a general model of the functions within an enterprise
which are concerned with the integration of business and control. It presents, in detail, an
abstract model of control functions and, in less detail, the business functions that interface to
control. The purpose is to establish a common terminology for functions involved in
information exchange.
The intent of Clause 7 is to state in detail the objects that make up the information streams
defined in Clause 6. The purpose is to establish a common terminology for the elements of
information exchanged.
Annex A defines the relationship of this standard with other related standardization work in
the manufacturing area.
The intent of Annex B is to present the business reasons for the information exchange
between business and control functions. The purpose is to establish a common terminology
for the reason for information exchange.
Annex C discusses the rationale for multiple models.
Annex D contains selected elements from the Purdue Reference Model that may be used to
place the functions described in Clauses 5 and 6 in context with the entire model.
Annex E is informative. It correlates the Purdue Reference Model to the MESA International
Model.
This standard is intended for those who are
– involved in designing, building, or operating manufacturing facilities;
– responsible for specifying interfaces between manufacturing and process control systems
and other systems of the business enterprise; or
– involved in designing, creating, marketing, and integrating automation products used to
interface manufacturing operations and business systems.

Annex F is a discussion of systems, resources, capability, capacity, and time as used in this
standard.

ENTERPRISE-CONTROL SYSTEM INTEGRATION –

Part 1: Models and terminology

1 Scope
This part of IEC 62264 describes the 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 by this standard. The goal is to
reduce the risk, cost, and errors associated with implementing these interfaces.
The standard can be used to reduce the effort associated with implementing new product
offerings. The goal is to have enterprise systems and control systems that inter-operate and
easily integrate.
The scope of this standard is limited to
a) a presentation of the scope of the manufacturing operations and control domain;
b) a discussion of the organization of physical assets of an enterprise involved in
manufacturing;
c) a listing of the functions associated with the interface between control functions and
enterprise functions; and
d) a description of the information that is shared between control functions and enterprise
functions.

4 Enterprise-control system integration overview
4.1 Introduction
Successfully addressing the issue of enterprise-control system integration requires identifying
the boundary between the enterprise and the manufacturing operations and control domains
(MO&C). The boundary is identified using relevant models that represent functions, physical
equipment, information within the MO&C domain, and information flows between the domains.
Multiple models show the functions and integration associated with control and enterprise
systems.
a) Hierarchy models that describe the levels of functions and domains of control associated
within manufacturing organizations are presented in Clause 5. These models are based on
The Purdue Reference Model for CIM, referenced as PRM; the MESA International
Functional Model; and the equipment hierarchy model from IEC 61512-1.
NOTE 1 Selected elements of the Purdue Reference Model for CIM are included in Annex D.
NOTE 2 See the Bibliography for reference to the MESA white paper defining MES functionality.

b) A data flow model that describes the functional and data flows within manufacturing
organizations is given in Clause 6. This model is also based on The Purdue Reference
Model for CIM.
c) An object model that describes the information that may cross the enterprise and control
system boundary is given in Clause 7.

This standard provides models and information in multiple levels of detail and abstraction.
These levels are illustrated in Figure 1, which serves as a map to the rest of the document.
Each model and diagram increases the level of detail presented in the previous model.
The models start with a description of the domain of control systems and the domain of
enterprise systems. The domain discussion is contained in Clause 5.
Functions within the domains are presented in Clauses 5 and 6. Functions of interest that are
relevant to the standard are also given a detailed description in Clause 6. The information
flows of interest between the relevant functions are listed in 6.5.
The categories of information are given in 7.2. The formal object model of the information of
interest is presented in 7.5, 7.6, 7.7, and 7.8.
4.2 Criteria for inclusion in manufacturing operations and control domain
The hierarchy and data flow models describe most of the functions within a manufacturing
enterprise. Only some of those functions are associated with manufacturing control and
manufacturing control systems. The following list shows the criteria used to determine which
functions and which information flows are included in this standard.
a) The function is critical to maintaining regulatory compliance. This includes such factors as
safety, and compliance to environmental and current good manufacturing practices.
b) The function is critical to plant reliability.
c) The life impacts the operation phase of the life of a facility, as opposed to the design,
construction, and disposal phases of the life of a facility.
d) The information is needed by facility operators in order to perform their jobs.

The information that flows between functions identified as being within the control domain
and those outside the control domain describe the enterprise-control system boundary.
Information exchanged between functions within the control domain and information
exchanged between functions outside the control domain are outside the scope of this
document. Figure 2 illustrates the enterprise-control system interface, as depicted in the data
flow model, between control and non-control functions; the blue circles indicate functions that
exchange information and are described in the data flow model. Functions depicted as white
circles and data flows depicted as dashed lines are those considered as outside the scope
of this standard.
