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 61784-1-6 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 61784-1-6:2023 © 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.
The text of this International Standard is based on the following documents:
Draft Report on voting
65C/1207/FDIS 65C/1236/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
A list of all parts of the IEC 61784-1 series, published under the general title Industrial networks

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.

Communication Profile Family 6
1 Scope
This part of IEC 61784-1 defines Communication Profile Family 6 (CPF 6). CPF 6 specifies a
set of protocol specific communication profiles (CPs) based on the IEC 61158 series (Type 8)
and other standards, to be used in the design of devices involved in communications in factory
manufacturing and process control.
NOTE 1 All CPs are based on standards or draft standards or International Standards published by the IEC or on
standards or International Standards established by other standards bodies or open standards processes.
NOTE 2 Some CPs of CPF 6 are specified in IEC 61784-2-6.
Each CP selects an appropriate consistent and compatible subset of services and protocols
from the relevant set that is defined and modelled in the IEC 61158 series. For the selected
subset of services and protocols, the profile also describes any possible or necessary
constraints in parameter values.
