Industrial communication networks - Fieldbus specifications - Part 6-14: Application layer protocol specification - Type 14 elements
IEC 61158-6-14:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-14, and define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 14 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are: - corrections of editorial errors; - specification changes for CPF4; - update of the requirements for all conformance classes; - update of the requirements for all conformance services.

Cette troisième édition annule et remplace la deuxième édition parue en 2010. Elle constitue une révision technique. Les principales modifications sont: - correction des erreurs éditoriales; - modifications de la spécification de la CPF4; - mise à jour des exigences de l'ensemble des classes de conformité; - mise à jour des exigences de l'ensemble des services de conformité.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 6-14. del: Specifikacija protokola na aplikacijski ravni - Elementi tipa 14 (IEC 61158-6-14:2014)
1.1 General
Aplikacijski nivo procesnih vodil (FAL) omogoča uporabniškim programom dostop do komunikacijskega okolja procesnih vodil. Glede na to je mogoče aplikacijski nivo procesnih vodil obravnavati kot »okno med ustreznimi aplikacijami«.
Ta standard določa skupne elemente za osnovne časovno kritične in časovno nekritične sporočilne komunikacije med aplikacijami v avtomatizacijskem okolju in material, specifičen za procesna vodila tipa 14. Izraz »časovno kritičen« se uporablja za predstavitev prisotnosti časovnega okna, v okviru katerega se zahteva dokončanje enega ali več opredeljenih dejanj z določeno stopnjo gotovosti. Zaradi neuspešnega dokončanja opredeljenih dejanj v časovnem oknu je možna odpoved aplikacij, ki zahtevajo dejanja, pri čemer so ogroženi oprema, obrat in morda človeška življenja.
Ta standard opredeljuje interakcije med oddaljenimi aplikacijami in določa zunanje vidno vedenje, ki ga zagotavlja aplikacijski nivo procesnih vodil tipa 13 v smislu
a) formalne abstraktne sintakse, ki določa podatkovne enote protokola aplikacijskega nivoja, ki se prenašajo med aplikacijskimi osebki, ki komunicirajo;
b) prenosne sintakse, ki opredeljuje pravila kodiranja, ki se uporabljajo za podatkovne enote protokola aplikacijskega nivoja;
c) stroja stanja aplikacijskega konteksta, ki opredeljuje vedenje aplikacijskega opravila, vidnega med aplikacijskimi osebki, ki komunicirajo;
d) strojev stanja aplikacijskega razmerja, ki opredeljujejo komunikacijsko vedenje med aplikacijskimi osebki, ki komunicirajo.
Namen tega standarda je opredeliti protokol, ki se zagotavlja za
a) določitev žične predstavitve primitivov opravil iz standarda IEC 61158-5-14, in
b) določitev zunanje vidnega vedenja, povezanega z njihovim prenosom.
Ta standard določa protokol aplikacijskega nivoja procesnih vodil tipa 14 v skladu z osnovnim referenčnim modelom OSI (ISO/IEC 7498) in strukturo aplikacijskega nivoja OSI (ISO/IEC 9545).

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

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 protocol provides the application service by making use of the services
available from the data-link or other immediately lower layer. The primary aim of this standard
is to provide a set of rules for communication expressed in terms of the procedures to be
carried out by peer application entities (AEs) at the time of communication. These rules for
communication are intended to provide a sound basis for development in order to serve a
variety of purposes:
• as a guide for implementors and designers;
• for use in the testing and procurement of equipment;
• as part of an agreement for the admittance of systems into the open systems environment;
• as a refinement to the understanding of time-critical communications within OSI.
This standard is concerned, in particular, with the communication and interworking of sensors,
effectors and other automation devices. By using this standard together with other standards
positioned within the OSI or fieldbus reference models, otherwise incompatible systems may
work together in any combination.

Part 6-14: Application layer protocol specification –
Type 14 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 14 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 specifies interactions between remote applications and defines the externally
visible behavior provided by the Type 14 fieldbus application layer in terms of
a) the formal abstract syntax defining the application layer protocol data units conveyed
between communicating application entities;
b) the transfer syntax defining encoding rules that are applied to the application layer
protocol data units;
c) the application context state machine defining the application service behavior visible
between communicating application entities;
d) the application relationship state machines defining the communication behavior visible
between communicating application entities.
The purpose of this standard is to define the protocol provided to
a) define the wire-representation of the service primitives defined in IEC 61158-5-14, and
b) define the externally visible behavior associated with their transfer.
This standard specifies the protocol of the Type 14 fieldbus application layer, in conformance
with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI application layer structure
(ISO/IEC 9545).
1.2 Specifications
The principal objective of this standard is to specify the syntax and behavior of the application
layer protocol that conveys the application layer services defined in IEC 61158-5-14.
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
protocols standardized in the IEC 61158-6 series.

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.
Conformance is achieved through implementation of this application layer p
