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.
Attention is drawn to the fact that the use of some of the associated protocol types is restricted
by their intellectual-property-right holders. In all cases, the commitment to limited release of
intellectual-property-rights made by the holders of those rights permits a layer protocol type to
be used with other layer protocols of the same type, or in other type combinations explicitly
authorized by their respective intellectual property right holders.
NOTE Combinations of protocol types are specified in the IEC 61784-1 series and the IEC 61784-2 series.
IEC 61784-1-0 has been prepared by subcommittee 65C: Industrial networks, of IEC technical
committee 65: Industrial-process measurement, control and automation. It is an International
Standard.
This first edition, together with the other parts of the same series, cancels and replaces the fifth
edition of IEC 61784-1 published in 2019. This first edition constitutes a technical revision.

– 4 – IEC 61784-1-0:2023 © IEC 2023
This edition includes the following significant technical changes with respect to
IEC 61784-1:2019:
a) split of the original IEC 61784-1 into several subparts, one subpart for the material of a
generic nature, and one subpart for each Communication Profile Family specified in the
original document;
b) move most contents of the original scope into a new dedicated subclause;
c) addition of a new Communication Profile Family (CPF 22).
The text of this International Standard is based on the following documents:

INTRODUCTION
The IEC 61784-1 series provides a set of Communication Profiles (CP) in the sense of
ISO/IEC TR 10000-1. These answer the need of identifying the protocol families co-existing
within the IEC 61158 series, as a result of the international harmonization of fieldbus
technologies available on the market. More specifically, these profiles help to correctly state
the compliance with the IEC 61158 series, and to avoid the spreading of divergent
implementations, which would limit its use, clearness and understanding. Additional profiles to
address specific market concerns, such as functional safety or information security, can be
addressed by future parts of the IEC 61784-1 series.
The IEC 61784-1 series contains several Communication Profile Families (CPF), which specify
one or more communication profiles. Such profiles identify, in a strict sense, protocol subsets
of the IEC 61158 series via protocol specific communication profiles. They do not define device
profiles that specify communication profiles together with application functions needed to
answer the need of a specific application ("application profiles").
It is agreed that these latter classes of profiles would facilitate the use of the IEC 61158 series
of standards; the profiles defined in the IEC 61784-1 series are a necessary step to achieve
that task.
It is also important to clarify that interoperability – defined as the ability of two or more network
systems to exchange information and to make mutual use of the information that has been
exchanged (see ISO/IEC TR 10000-1) – can be directly achieved on the same link only for those
devices complying with the same communication profile.
Profiles contained in the IEC 61784-1 series are constructed of references to IEC 61158-2 and
the IEC 61158-3, IEC 61158-4, IEC 61158-5 and IEC 61158-6 series, and other IS, TS or
worldwide-accepted standards, as appropriate . Each profile is required to reference at least
one part of the IEC 61158 series in addition to IEC 61158-1.
Two or more Profiles, which are related to a common family, are specified within a
"Communication Profile Family" (CPF).

___________
International Standardised Profiles may contain normative references to specifications other than International
Standards; see ISO/IEC JTC 1 N 4047: The Normative Referencing of Specifications other than International
Standards in JTC 1 International Standardized Profiles – Guidelines for ISP Submitters.

General concepts and terminology

1 Scope
The IEC 61784-1 series defines several Communication Profile Families (CPF). Each CPF
specifies a set of protocol specific communication profiles (CPs) based primarily on the
IEC 61158 series, to be used in the design of devices involved in communications in factory
manufacturing and process control.
This part of IEC 61784-1 defines a common terminology for all CPFs and conventions to be
used in the specification of the CPs. It also provides a compliance statement and an overview
of the structure and contents of the CPFs in the IEC 61784-1 series.
NOTE The added value of the IEC 61784-1 series is explained in Annex A.

4 Conformance to communication profiles
Each communication profile within the IEC 61784-1 series includes part of the IEC 61158
series. It may also include parts of other standards or international specifications.
A statement of compliance with a Communication Profile Family n (CPF n) of the IEC 61784-1
series shall be stated as either
Compliance with IEC 61784-1-n:2023
or
Compliance with IEC 61784-1-n (Ed.1.0)
and a statement of compliance with a Communication Profile (CP) of the IEC 61784-1 series
shall be stated as either
Compliance with IEC 61784-1-n:2023 CP n/m
or
Compliance with IEC 61784-1-n (Ed.1.0) CP n/m
where the Type within the angle brackets < > is optional and the angle brackets are not to be
included.
Product standards shall not include any conformity assessment aspects (including QM
provisions), neither normative nor informative, other than provisions for product testing
(evaluation and examination).
5 Communication profiles and communication profile families
Each CP selects specifications for the communications protocol stack at a device. It contains a
minimal set of required services at the application layer and specification of options in
intermediate layers defined through references. If no application layer is included, then a
minimal set of required services at the Data-link layer is specified. The appropriate references
to the protocol specific types are given in each communication profile family or associated
profiles.
NOTE All CPs are based on standards or draft standards or International Standards published by the IEC or from
standards or International Standards established by other standards bodies or open standards processes.
The structure of CPFs is specified in Figure 1.

Annex A
(informative)
Added value of the IEC 61784-1 series
The approval of the IEC 61784-1 series as an International Standard means that a number of
industry specifications for field communication have well-defined communication stacks
(physical layer, data-link layer, application layer).
The added value of the IEC 61784-1 series is that:
– It is the guideline to properly use the IEC 61158 series of International Standards.
– The communication profiles are fully defined and available as International Standards.
– Devices declared fully compliant with one of these profiles are usable on the same network
(they support the basic level of interoperability).
– Compliance may be supported by independent organizations.
– It gives the possibility to reference other existing national and international standards, where
neither IEC nor ISO have equivalent standards.
– The harmonization work done in the IEC 61158 series resulted in the identification of some
common views, concepts, definitions, and approaches. This helps understand the basis of
fieldbus technologies.
– The IEC 61784-1 series specifies the different fieldbus concepts in one International
Standard. This is a first and important step forward in resolving difficulty in comparing
market products and performances.
The communication profiles give the normative basis needed to support the complementary
work about the application functions.

Concepts généraux et terminologie

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l’ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l’électricité et de l’électronique. A cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d’études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l’Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC intéressés
sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s’assure de l’exactitude du contenu technique de ses Publications; l’IEC ne peut pas être tenue responsable de
l’éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d’encourager l’uniformité internationale, les Comités nationaux de l’IEC s’engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d’évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n’est responsable d’aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s’assurer qu’ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d’études et des Comités nationaux de l’IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l’utilisation de cette Publication de l’IEC ou de toute autre Publication de l’IEC,
ou au crédit qui lui est accordé.
8) L’attention est attirée sur les références normatives citées dans cette publication. L’utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de l’IEC peuvent faire l’objet
de droits de brevet. L’IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de
propriété et averti de leur existence.
L’attention est attirée sur le fait que l’utilisation de certains des types de protocoles associés
est restreinte par les détenteurs des droits de propriété intellectuelle. En tout état de cause,
l’engagement de renonciation partielle aux droits de propriété intellectuelle pris par les
détenteurs de ces droits autorise l’utilisation d’un type de protocole de couche avec les autres
protocoles de couche du même type, ou dans des combinaisons avec d’autres types autorisées
explicitement par les détenteurs respectifs des droits de propriété intellectuelle pour ces types.
NOTE Les combinaisons de types de protocoles sont spécifiées dans la série IEC 61784-1 et dans la série
IEC 61784-2.
L’IEC 61784-1-0 a été établie par le sous-comité 65C: Réseaux industriels, du comité
d’études 65 de l’IEC: Mesure, commande et automation dans les processus industriels Il s’agit
d’une Norme internationale.

Cette première édition, conjointement avec les autres parties de la même série, annule et
remplace la cinquième édition de l’IEC 61784-1 parue en 2019. Cette première édition constitue
une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à
l’IEC 61784-1:2019:
a) scission de l’IEC 61784-1 d’origine en plusieurs sous-parties, une sous-partie pour le
matériel de nature générique et une sous-partie pour chaque famille de profils de
communication spécifiée dans le document d’origine;
b) déplacement de la plupart des contenus du domaine d’application d’origine dans un
nouveau paragraphe dédié;
c) ajout d’une nouvelle famille de profils de communication (CPF 22).
