Industrial communication networks - Fieldbus specifications - Part 3-7: Data-link layer service definition - Type 7 elements

It 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.

La CEI 61158-3-7:2007 définit de manière abstraite le service visible de l'extérieur fourni par la couche de liaison de données de bus de terrain de Type 7 en termes: - d'actions et événements primitifs du service; - de paramètres associés à chaque action primitive et événement primitif, et la forme qu'ils prennent; - de l'interrelation entre ces actions et événements, et leurs séquences valides. Cette première édition et ses parties associées de la sous-série CEI 61158-3 annulent et remplacent la CEI 61158-3:2003. La présente édition de cette partie constitue une révision rédactionnelle. Cette édition inclut les modifications suivante: - suppression du précédent bus de terrain de Type 6, et du paramètre fictif pour une couche de liaison de données des bus de terrain de Type 5, en raison d'un manque de pertinence avec le marché; - ajout de nouveaux types de bus de terrain; division de cette partie en plusieurs parties numérotées 3-1, 3-2,..., 3-19. La présente version bilingue (2013-07) 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.
