Industrial communication networks - Fieldbus specifications - Part 1: Overview and guidance for the IEC 61158 and IEC 61784 series

IEC 61158-1:2019 specifies the generic concept of fieldbuses. This document presents an overview and guidance for the IEC 61158 series explaining the structure and content of the IEC 61158 series, relating the structure of the IEC 61158 series to the ISO/IEC 7498-1 OSI Basic Reference Model and showing how to use parts of the IEC 61158 series in combination with the IEC 61784 series. It also provides explanations of some aspects of the IEC 61158 series that are common to the type specific parts of the IEC 61158 5 including the application layer service description concepts and the generic fieldbus data types. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
• updates of the references to and information about the IEC 61158 series, IEC 61784 1, IEC 61784 3, IEC 61784-5 series and IEC 61918 throughout the document;
• new Type 25 and the related profile family CPF 20;
• new Type 26 and the related profile family CPF 21.

Part 1: Overview and guidance for the IEC 61158 and IEC 61784 series
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 IEC 61784-1 and IEC 61784-2.

International Standard IEC 61158 1 has been prepared by subcommittee 65C: Industrial

networks, of IEC technical committee 65: Industrial-process measurement, control and

automation.

This second edition cancels and replaces the first edition published in 2014. This edition

constitutes a technical revision.

This edition includes the following significant changes with respect to the previous edition:

• updates of the references to and information about the IEC 61158 series, IEC 61784-1,

IEC 61784-3, IEC 61784-5 series and IEC 61918 throughout the document;
• new Type 25 and the related profile family CPF 20;
• new Type 26 and the related profile family CPF 21.
The text of this International Standard is based on the following documents:

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.
The French version of this standard has not been voted upon.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts of the IEC 61158 series, published under the general title Industrial

communication networks – Fieldbus specifications, can be found on the IEC web site.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
