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.

Attention is drawn to the fact that the use of the associated protocol type is restricted by its

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 its intellectual-property-right holders.

NOTE Combinations of protocol types are specified in IEC 61784-1 and IEC 61784-2.

International Standard IEC 61158-3-22 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 2010. This edition

constitutes a technical revision. This edition includes the following technical changes with

respect to the previous edition.
• Introduction of two new topology scan services.
• Marking old topology scan services as to be discontinued.

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

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be:
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

INTRODUCTION

This part of IEC 61158 is one of a series produced to facilitate the interconnection of

automation system components. It is related to other standards in the set as defined by the

“three-layer” fieldbus reference model described in IEC 61158-1.

Throughout the set of fieldbus standards, the term “service” refers to the abstract capability

provided by one layer of the OSI Basic Reference Model to the layer immediately above.

Thus, the data-link layer service defined in this standard is a conceptual architectural service,

independent of administrative and implementation divisions.

The International Electrotechnical Commission (IEC) draws attention to the fact that it is

claimed that compliance with this document may involve the use of patents concerning

Type 22 elements and possibly other types:

IEC takes no position concerning the evidence, validity and scope of these patent rights.

The holders of these patent rights have assured IEC that they are willing to negotiate licenses

either free of charge or under reasonable and non-discriminatory terms and conditions with

applicants throughout the world. In this respect, the statement of the holders of these patent

rights is registered with IEC. Information may be obtained from:
[PI] Pilz GmbH & Co. KG
Felix-Wankel-Str. 2
73760 Ostfildern
Germany

Attention is drawn to the possibility that some of the elements of this document may be the

subject of patent rights other than those identified above. IEC shall not be held responsible for

identifying any or all such patent rights.

ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of

patents relevant to their standards. Users are encouraged to consult the data bases for the

most up to date information concerning patents.

INDUSTRIAL COMMUNICATION NETWORKS –
FIELDBUS SPECIFICATIONS –
Part 3-22: Data-link layer service definition –
Type 22 elements
1 Scope
1.1 General

This part of IEC 61158 provides common elements for basic time-critical messaging

communications between devices in an automation environment. The term “time-critical” is

used to represent the presence of a time-window, within which one or more specified actions

are required to be completed with some defined level of certainty. Failure to complete

specified actions within the time window risks failure of the applications requesting the

actions, with attendant risk to equipment, plant and possibly human life.

This standard defines in an abstract way the externally visible service provided by the

Type 22 fieldbus data-link layer in terms of:
a) the primitive actions and events of the service;

b) the parameters associated with each primitive action and event, and the form which they

take; and

c) the interrelationship between these actions and events, and their valid sequences.

The purpose of this standard is to define the services provided to:

• the Type 22 fieldbus application layer at the boundary between the application and data-

link layers of the fieldbus reference model; and
• systems management at the boundary between the data-link layer and systems
management of the fieldbus reference model.
1.2 Specifications

The principal objective of this standard is to specify the characteristics of conceptual data-link

layer services suitable for time-critical communications, and thus supplement the OSI Basic

Reference Model in guiding the development of data-link protocols for time-critical

communications. A secondary objective is to provide migration paths from previously-existing

industrial communications protocols.

This specification may be used as the basis for formal DL-Programming-Interfaces.

Nevertheless, it is not a formal programming interface, and any such interface will need to

address implementation issues not covered by this specification, including:
a) the sizes and octet ordering of various multi-octet service parameters; and

b) the correlation of paired request and confirm, or indication and response, primitives.

1.3 Conformance

This standard does not specify individual implementations or products, nor do they constrain

the implementations of data-link entities within industrial automation systems.

There is no conformance of equipment to this data-link layer service definition standard.

Instead, conformance is achieved through implementation of the corresponding data-link

protocol that fulfils the Type 22 data-link layer services defined in this standard.
