Industrial communication networks - Fieldbus specifications - Part 4-3: Data-link layer protocol specification - Type 3 elements (IEC 61158-4-3:2014)

IEC 61158-4-3:2014 specifies procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entities forming the distributed data-link service provider and the structure of the fieldbus DLPDUs used for the transfer of data and control information by the protocol of this standard, and their representation as physical interface data units. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are:
- Corrections in Table A.15 and Table A.16;
- Expired patent removed and added new patents.

L'IEC 61158-4-3:2014 spécifie les procédures pour le transfert en temps utile de données et d'informations de commande d'une entité d'utilisateur de liaison de données vers une entité d'utilisateur homologue, et parmi les entités de liaison de données formant le fournisseur de service de liaison de données distribué et la structure des DLPDU du bus de terrain utilisée pour le transfert de données et d'informations de commande par le protocole de la présente norme, et leur représentation comme unités de données d'interface physique. Cette troisième édition annule et remplace la deuxième édition, parue en 2010. Elle constitue une révision technique. Les modification sont:
- Des corrections ont été apportées au Tableau A.15 et au Tableau A.16;
- Les brevets qui ont expiré ont été retirés et de nouveaux brevets ont été ajoutés.

IEC 61158-4-3:2014 določa postopke za pravočasni prenos podatkov in informacij o nadzoru od enega uporabniškega osebka podatkovne povezave do uporabniškega osebka vrstnika in med osebki podatkovne povezave, ki tvorijo ponudnika storitev porazdeljenih podatkovnih povezav, ter strukturo DLPDU-jev za procesna vodila, ki se uporabljajo za prenos podatkov in informacij o nadzoru s protokolom tega standarda, in njihovo zastopanost kot fizični vmesnik podatkovnih enot. Ta tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2010, in predstavlja tehnično popravljeno izdajo. Glavne spremembe so:
– Popravki v preglednici A.15 in preglednici A.16;
– Odstranjen potekli patent in dodani novi patenti.

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
...
