Industrial communication networks - Fieldbus specifications - Part 3-12: Data-link layer service definition - Type 12 elements

IEC 61158-3-12:2007 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. It includes the following significant changes with respect to the previous edition deletion of the former Type 6 fieldbus, and the placeholder for a Type 5 fieldbus data-link layer, for lack of market relevance; addition of new types of fieldbuses; division of this part into multiple parts numbered.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 3-12: Définition des services de la couche liaison de données - Éléments de Type 12

L'IEC 61158-3-12:2007 définit de manière abstraite le service visible de l'extérieur fourni par la couche liaison de données de réseau de terrain Type 12. Le but de la présente norme est de définir les services fournis à la couche application de réseau de terrain Type 12 au niveau de la frontière entre l'application et les couches liaison de données du modèle de référence de réseau de terrain ainsi que la gestion des systèmes au niveau de la frontière entre la couche liaison de données et la gestion des systèmes selon le modèle de référence de bus de terrain. Cette première édition et les autres normes de la sous-partie CEI 61158-3 annulent et remplacent la CEI 61158-3:2003. Elle constitue un ajout technique. La présente partie ainsi que les normes connexes traitant du Type 12 remplacent également la CEI/PAS 62407, parue en 2005. Elle inclut les modifications suivantes: suppression de l'ancien bus de terrain de Type 6, et du paramètre fictif pour une couche liaison de données de bus de terrain de Type 5, qui ne sont plus adaptés au marché; ajout de nouveaux types de bus de terrain; division de la présente partie en plusieurs parties numérotées 3-1, 3-2, , 3-19. La présente version bilingue (2014-06) correspond à la version anglaise monolingue publiée en 2007-12.

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.

NOTE  Use of some of the associated protocol types is restricted by their intellectual-property-right holde
