Function blocks - Part 1: Architecture (IEC 61499-1:2012)
This part of IEC 61499 defines a generic architecture and presents guidelines for the use of function blocks in distributed industrial-process measurement and control systems (IPMCSs). This architecture is presented in terms of implementable reference models, textual syntax and graphical representations. These models, representations and syntax can be used for:
- the specification and standardization of function block types;
- the functional specification and standardization of system elements;
- the implementation independent specification, analysis, and validation of distributed IPMCSs;
- the configuration, implementation, operation, and maintenance of distributed IPMCSs;
- the exchange of information among software tools for the performance of the above functions.
This part of IEC 61499 does not restrict or specify the functional capabilities of IPMCSs or their system elements, except as such capabilities are represented using the elements defined herein. IEC 61499-4 addresses the extent to which the elements defined in this standard may be restricted by the functional capabilities of compliant systems, subsystems, and devices. Part of the purpose of this standard is to provide reference models for the use of function blocks in other standards dealing with the support of the system life cycle, including system planning, design, implementation, validation, operation and maintenance. The models given in this standard are intended to be generic, domain independent and extensible to the definition and use of function blocks in other standards or for particular applications or application domains. It is intended that specifications written according to the rules given in this standard be concise, implementable, complete, unambiguous, and consistent.

Blocs fonctionnels - Partie 1: Architecture (CEI 61499-1:2012)
La CEI 61499-1:2012 définit une architecture générique et présente des lignes directrices pour l'utilisation de blocs fonctionnels dans des systèmes de mesure et de commande dans les processus industriels distribués (IPMCS). Cette architecture est présentée en termes de modèles de référence pouvant être mis en oeuvre, de syntaxe textuelle et de représentations graphiques. Les modèles donnés dans la présente norme sont censés être génériques, indépendants vis-à-vis de tout domaine et extensibles à la définition et à l'utilisation de blocs fonctionnels dans d'autres normes ou pour des applications particulières ou des domaines d'application particuliers. L'intention est de faire en sorte que les spécifications écrites selon les règles données dans la présente norme soient concises, réalisables, complètes, non ambiguës et cohérentes. Cette deuxième édition annule et remplace la première édition parue en 2005 et constitue une révision technique. Cette édition inclut des modifications techniques majeures liées aux: terme contrôle d'exécution, variables temporaires, séquences de service, syntaxe pour le mapping des instances FB, syntaxe relative à la définition des types de segment, commandes de gestion READ/WRITE.
Funkcijski bloki - 1. del: Arhitektura (IEC 61499-1:2012)
Ta del standarda IEC 61499 določa generično arhitekturo in predstavlja smernice za uporabo funkcijskih blokov v razširjenih sistemih merjenja in krmiljenja industrijskih postopkov (IPMCS). Ta arhitektura je predstavljena v smislu izvedljivih referenčnih modelov, skladnje besedila in grafičnih prikazov. Ti modeli, prikazi in skladnja se lahko uporabljajo za:
– specifikacijo in standardizacijo vrst funkcijskih blokov;
– funkcijsko specifikacijo in standardizacijo sistemskih elementov;
– specifikacijo, analizo in ovrednotenje razširjenih sistemov merjenja in krmiljenja industrijskih postopkov, ki niso odvisni od izvedbe;
– konfiguracijo, implementacijo, delovanje in vzdrževanje razširjenih sistemov merjenja in krmiljenja industrijskih postopkov;
– izmenjavo podatkov med programskimi orodji za izvajanje navedenih funkcij.
Ta del standarda IEC 61499 ne omejuje ali določa funkcijskih zmožnosti sistemov merjenja in krmiljenja industrijskih postopkov ali njihovih sistemskih elementov, razen če so navedene zmožnosti predstavljene z uporabo elementov, opredeljenih v tem dokumentu. Standard IEC 61499-4 obravnava, do kakšne mere so lahko elementi, opredeljeni v tem standardu, omejeni s funkcijskimi zmožnostmi skladnih sistemov, podsistemov in naprav. Med nameni tega standarda je zagotoviti referenčne modele za uporabo funkcijskih blokov v drugih standardih, ki obravnavajo podporo življenjskemu ciklu sistema, vključno s sistemskim načrtovanjem, projektiranjem, izvedbo, vrednotenjem, delovanjem in vzdrževanjem. Modeli, podani v tem standardu, naj bi bili splošni in neodvisni od področja, pri čemer se jih lahko razširi na opredelitev in uporabo funkcijskih blokov iz drugih standardov ali se jih uporabi za določeno vrsto uporabe oz. področje uporabe. Specifikacije, napisane v skladu s pravili iz tega standarda, naj bi bile jedrnate, izvedljive, popolne, jasne in usklajene.

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.
International Standard IEC 61499-1 has been prepared by subcommittee 65B: Measurement
and control devices, of IEC technical committee 65: Industrial-process measurement, control
and automation.
This second edition cancels and replaces the first edition published in 2005. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• Execution control in basic function blocks (5.2) has been clarified and extended:
– Dynamic and static parts of the EC transition condition are clearly delineated by using
the ec_transition_event[guard_condition] syntax of the Unified Modeling
Language (UML) (5.2.1.3, B.2.1).
– The terminology "crossing of an EC transition" (3.10) is used preferentially to "clearing"
to avoid the misinterpretation that the entire transition condition corresponds to a
Boolean variable that can be "cleared."

rigorous.
– Event and data outputs of adapter instances (plugs and sockets) can be used in EC
transition conditions, and event inputs of adapter instances can be used as EC action
outputs.
• Temporary variables (3.97) can be declared (B.2.1) and used in algorithms of basic
function blocks.
• Service sequences (6.1.3) can now be defined for basic and composite function block
types and adapter types, as well as service interface types.
