Overview - EN IEC 61158-1:2019 (Fieldbus specifications, Part 1)

EN IEC 61158-1:2019 provides an authoritative overview and implementation guidance for the IEC 61158 and IEC 61784 series of fieldbus standards. It defines the generic concept of fieldbuses, describes the structure and content of the IEC 61158 series, maps fieldbus concepts onto the ISO/IEC 7498-1 OSI Basic Reference Model, and explains how to combine IEC 61158 parts with the IEC 61784 profile series. This second edition (2019) replaces the 2014 edition and incorporates updates including the introduction of Type 25 and Type 26 fieldbus types and their related profile families (CPF 20 and CPF 21).

Key topics and technical requirements

  • Fieldbus architecture and scope - generic concepts common to all IEC 61158 fieldbus types.
  • OSI mapping - relation of physical, data-link and application layer services and protocols to the OSI Basic Reference Model.
  • Application layer service descriptions - guidance on the formal style and concepts used across type-specific parts.
  • Generic fieldbus data types - explanations of common data-type usage shared by multiple fieldbus types.
  • Structure of IEC 61158 and IEC 61784 - how parts (physical, data-link, application) and IEC 61784 profiles interrelate for implementation and interoperability.
  • Profile guidance - use of IEC 61784 functional, installation and safety communication profiles alongside IEC 61158.
  • Updates - references and cross-links to related series (IEC 61784-1, IEC 61784-3, IEC 61784-5, IEC 61918) and the addition of new type/profile families (CPF 20/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.

4 Guidelines for implementers and users
4.1 Background and purpose
Communication in global markets requires a global understanding of a specification (standard
or not). ISO/OSI related specifications provide a common basis for understanding and
acceptance between international experts (manufacturers and end-users).

– 10 – IEC 61158-1:2019 © IEC 2019
Examples are
• ISO/IEC 7498-1 for general layering and structuring;
• ISO/IEC 9545 for general application layer modeling;
• ISO/IEC 8886 for data-link layer modeling.
The IEC 61158 series specifies a number of different fieldbus types in each of its parts
(IEC 61158-2 and the type specific parts of IEC 61158-3-tt, IEC 61158-4-tt, IEC 61158-5-tt
and IEC 61158-6-tt). As a result of the editorial harmonization work done by IEC, each PhL,
DLL and AL specification within IEC 61158 is shown in a homogeneous way. The description
of each layer offers, as far as possible, common views, concepts, definitions, and descriptive
methods.
NOTE The list of IEC 61158 parts is abbreviated as IEC 61158-3-tt, IEC 61158-4-tt, IEC 61158-5-tt, or
IEC 61158-6-tt, where tt represents one or more type numbers.
This common approach has been adopted to assist users and implementers in understanding
the several specifications. It is also intended to assist in comparing available products and
their communications-related features.
4.2 Supported options
Most of the fieldbus types specified in the IEC 61158 series include a range of selectable and
configurable options within their detailed specifications. In general, only certain restricted
combinations of options will interwork or interoperate correctly.
The recommended combinations of options are collected in IEC 61784-1 and IEC 61784-2.
IEC 61784-1 and IEC 61784-2 provide users and implementers with details of supported
fieldbus specifications based on selected options that are intended to work together
consistently and correctly. In most cases, available product demonstrations and working plant
experience support these profiles.
Annex A of IEC 61784-1 and Annex A of IEC 61784-2 help select the needed fieldbus by
showing the key features of each of the profiled fieldbus protocol families.
As a result, the route map recommended to select a fieldbus is:
• Clause 5 to Clause 8 of this part of IEC 61158;
• IEC 61784-1, Annex A: Communication concepts;
• IEC 61784-2, Annex A: Performance indicator calculation;
• IEC 61784-1 and IEC 61784-2, Communication profile family;
• the parts of IEC 61158 as referenced in IEC 61784-1 and IEC 61784-2 for the selected
communication profile of interest.
4.3 Benefits from using a common and formal style
The benefits gained from using a common and formal style to specify the communication
system are:
• the common look and feel of a specification saves effort during evaluation;
• a common structure helps to identify and to specify common parts and contents;
• the common approach represents a first step to ensure long-term quality and stability;
• the missing parts and items of any specification are more readily identified by comparison
with the other specifications, leading to a simplified review and evaluation procedure;
• a common basis facilitates the development of test and certification procedures;

IEC 61158-1:2019 © IEC 2019 – 11 –
• the modular concepts support future enhancements, extensions and adaptation of new
technologies.
5 Concept of the IEC 61158 series
Conceptually, a fieldbus is an industrial digital communication network for integration of
industrial control and instrumentation devices into a system. Examples of such devices are
transducers, sensors, actuators and controllers.
The IEC 61158 series specifies a number of fieldbus protocol types. Each protocol type is
designed to permit multiple measurement and control devices to communicate. Devices
communicate directly only with other devices of the same protocol type. The basic
requirements of industrial communication networks for measurement and control are given in
Clause 11.
Devices which use the same lower-layer protocols in a compatible fashion but differ in their
higher-layer protocols may be able to share a lower-layer medium.
In all cases, a particular data-link layer protocol type may be used without restriction when
coupled with physical layer and application layer protocols of the same type or with other
combinations as specified in IEC 61784-1 and IEC 61784-2. Use of the various protocol types
in other combinations may require permission from their respective copyright holders.
The protocol types in IEC 61158 have been engineered to support information pro
