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 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 61158-5-22 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.

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.

The application service is provided by the application protocol making use of the services

available from the data-link or other immediately lower layer. This standard defines the

application service characteristics that fieldbus applications and/or system management may

exploit.

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 application layer service defined in this standard is a conceptual architectural

service, independent of administrative and implementation divisions.

INDUSTRIAL COMMUNICATION NETWORKS –
FIELDBUS SPECIFICATIONS –
Part 5-22: Application layer service definition –
Type 22 elements
1 Scope
1.1 General

The fieldbus application layer (FAL) provides user programs with a means to access the

fieldbus communication environment. In this respect, the FAL can be viewed as a “window

between corresponding application programs.”

This standard provides common elements for basic time-critical and non-time-critical

messaging communications between application programs in an automation environment and

material specific to Type 22 fieldbus. 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 fieldbus

application layer in terms of

a) an abstract model for defining application resources (objects) capable of being

manipulated by users via the use of the FAL service;
b) the primitive actions and events of the service;

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

take; and

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

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

a) the FAL user at the boundary between the user and the application layer of the fieldbus

reference model; and
b) Systems Management at the boundary between the application layer and Systems
Management of the fieldbus reference model.

This standard specifies the structure and services of the fieldbus application layer, in

conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application

layer structure (ISO/IEC 9545).

FAL services and protocols are provided by FAL application-entities (AE) contained within the

application processes. The FAL AE is composed of a set of object-oriented application service

elements (ASEs) and a layer management entity (LME) that manages the AE. The ASEs

provide communication services that operate on a set of related application process object

(APO) classes. One of the FAL ASEs is a management ASE that provides a common set of

services for the management of the instances of FAL classes.

Although these services specify, from the perspective of applications, how request and

responses are issued and delivered, they do not include a specification of what the requesting

and responding applications are to do with them. That is, the behavioral aspects of the

applications are not specified; only a definition of what requests and responses they can

---------------------- Page: 9 ----------------------
– 8 – IEC 61158-5-22:2014 © IEC 2014

send/receive is specified. This permits greater flexibility to the FAL users in standardizing

such object behavior. In addition to these services, some supporting services are also defined

in this standard to provide access to the FAL to control certain aspects of its operation.

1.2 Specifications

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

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

OSI Basic Reference Model in guiding the development of application layer protocols for time-

critical communications.

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

communications protocols. It is this latter objective which gives rise to the diversity of services

standardized as the various Types of IEC 61158, and the corresponding protocols
standardized in subparts of IEC 61158-6.

This specification may be used as the basis for formal application 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 does it constrain

the implementations of application layer entities within industrial automation systems.

There is no conformance of equipment to this application layer service definition standard.

Instead, conformance is achieved through implementation of conforming application layer

protocols that fulfill the application layer services as defined in this standard.
