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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
Technical reports do not necessarily have to be reviewed until the data they provide are
considered to be no longer valid or useful by the maintenance team.
NOTE 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 particular data-link layer protocol Type to be used with physical layer and application layer protocols in Type
combinations as specified explicitly in the IEC 61784 series. Use of the various protocol types in other
combinations may require permission of their respective intellectual-property-right holders.
IEC 61158-1, which is a Technical Report, has been prepared by subcommittee 65C:
Industrial networks, of IEC technical committee 65: Industrial-process measurement, control
and automation.

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). Examples are
• ISO/IEC 7498 series 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 the parts of the
series (part 2 and the parts of part 3 through part 6). As a result of the editorial harmonization
---------------------- Page: 10 ----------------------
SIST-TP CLC/TR 61158-1:2009
TR 61158-1 © IEC:2007(E) – 7 –
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.
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 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:
5 to Clause 8 of this Technical Report
• Clause
• IEC 61784-1, Annex A: Communication concepts
• IEC 61784-2, Annex A: Performance indicator calculations
• IEC 61784-1 and IEC 61784-2, Communication Profile Family
• IEC 61158 series as appropriate for the particular fieldbus type 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;
• 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;
• modular concepts support future enhancements, extensions and adaptation of new
technologies.
5 Concept of IEC 61158 series
Conceptually, a fieldbus is a digital, serial, multidrop, data bus for communication with
industrial control and instrumentation devices such as – but not limited to – transducers,
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 on a shared
medium. Devices communicate directly only with other devices of the same protocol type.
---------------------- Page: 11 ----------------------
SIST-TP CLC/TR 61158-1:2009
– 8 – TR 61158-1 © IEC:2007(E)
NOTE 1 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.
NOTE 2 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.
These protocol types have been engineered to support information processing, monitoring
and control systems for any industrial sector and related domains. An example application for
high-integrity low-level communication between sensors, actuators and local controllers in a
process plant, together with the interconnection of programmable controllers, is shown in
Figure 1.

Figure 1 – Generic fieldbus network
A number of fieldbus types are specified in the IEC 61158 series using the following concepts
for decomposition.
a) First concept: The complex communication task is divided into different layers based on
an adaptation of ISO/IEC 7498, the ISO/OSI Basic Reference Model, thereby facilitating
well-structured functions and interfaces (see Clause 6). This has the following benefits:
⎯ decomposition of complex tasks;
⎯ modular structure to adapt different technologies.
b) Second concept: Each fieldbus type is composed of one or more layer specifications.
Most types include a number of services and protocol options that require an appropriate
selection to support a working system. Compatible selections of options and services
within one of the IEC 61158 fieldbus types are specified as standardized communication
profiles in IEC 61784-1 and IEC 61784-2. Most of these profiles are supported by
consortia or trade associations which are identified in the profile specification.
c) Third concept: The physical, data-link and application layers are described in
complementary ways, in terms of the offered services and the protocol which provides
those services.
Figure 2 illustrates the differences between service and protocol viewpoints of the data-link
and application layers. The protocol parts show the layer implementer’s view and the service
parts show the layer user’s view.

The application layer structure is as follows:
— the "what“ is described by application layer service elements (ASE); and
— the "how“ is described by application layer relationships (AR).
The data-link layer structure is as follows:
— the "what“ is described by data-link layer services and models; and
— the "how“ is described by data-link layer protocol machines and medium access principles.
The physical layer is structured similarly, but, because its services are readily described, they
occur in the same specification (IEC 61158-2) as the definitions of the physical protocols:
— the "what“ is described by physical layer services and models, and
— the "how“ is described by physical layer electromagnetic and mechanical specifications.
6 Mapping onto the OSI Basic Reference Model
6.1 Overview
IEC 61158 protocol types are described using the principles, methodology and model of
ISO/IEC 7498. The OSI model provides a layered approach to communications standards,
whereby the layers can be developed and modified independently. IEC 61158 specifies
functionality from top to bottom of a full OSI stack and, potentially, some functions for the
users of the stack. Functions of the intermediate OSI layers, layers 3 through 6, may be
consolidated into either the IEC 61158 data-link layer or the IEC 61158 application layer, or
may be realized by a separate layer. Likewise, some features common to users of the fieldbus
application layer may be provided by the IEC 61158 application
