Enterprise-control system integration - Part 6: Messaging service model (IEC 62264-6:2020)

This document defines a technology independent model for a set of abstract services that is
located above the application layer of the OSI model, and that is used for exchanging
transaction messages based on the transaction models defined in IEC 62264-5. The model,
which is called the Messaging Service Model (MSM), is intended for interoperability between
manufacturing operations domain applications and applications in other domains.
NOTE It is recognized that other sets of services not defined in accordance with this document are possible for the
exchange of MOM information and are not deemed invalid as a result of this document.

Intégration des systèmes entreprise-contrôle - Partie 6: Modèle de service de messagerie (IEC 62264-6:2020)

IEC 62264-6:2020 définit un modèle, indépendant de la technologie employée, pour un ensemble de services abstraits qui est situé au-dessus de la couche d'applications du modèle OSI et qui est utilisé pour échanger des messages de transaction sur la base des modèles de transaction définis dans l'IEC 62264-5. Le modèle, appelé Modèle de Service de Messagerie (MSM), est conçu pour l'interopérabilité entre les applications du domaine des opérations de fabrication et les applications d'autres domaines.

Integracija sistemov za upravljanje podjetij - 6. del: Model storitve sporočanja (IEC 62264-6:2020)

Ta dokument opredeljuje tehnološko neodvisen model za nabor abstraktnih storitev, ki je nad aplikacijsko plastjo modela OSI in se uporablja za izmenjavo transakcijskih sporočil na podlagi transakcijskih modelov, opredeljenih v standardu IEC 62264-5. Model, ki se imenuje Messaging Service Model (MSM), je namenjen interoperabilnosti med aplikacijami domene proizvodnih operacij in aplikacijami v drugih domenah.
OPOMBA: Za izmenjavo informacij MOM so možni tudi drugi sklopi storitev, ki niso opredeljeni v skladu s tem dokumentom, in se zaradi tega dokumenta ne štejejo za neveljavne.

ENTERPRISE-CONTROL SYSTEM INTEGRATION –

Part 6: Messaging service model

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.
International Standard IEC 62264-6 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee TC65: Industrial-process
measurement, control and automation.
The text of this International Standard is based on the following documents:

ENTERPRISE-CONTROL SYSTEM INTEGRATION –

Part 6: Messaging service model

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.
International Standard IEC 62264-6 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee TC65: Industrial-process
measurement, control and automation.
The text of this International Standard is based on the following documents:
FDIS Report on voting
65E/706/FDIS 65E/724/RVD
