Industrial communication networks - Fieldbus specifications - Part 4-3: Data-link layer protocol specification - Type 3 elements
IEC 61158-4-3:2019 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 fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. The main changes are: This edition includes the following significant technical changes with respect to the previous edition: •corrections in Table 3; •corrections in Table A.15; •spelling and grammar.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 4-3 : Spécification du protocole de la couche liaison de données - Éléments de Type 3
L'IEC 61158-4-3:2019 la couche liaison de données permet la communication de messages de base, critiques du point de vue temporel, entre appareils dans un environnement d'automatisation. Ce protocole donne les moyens de communiquer à un sous-ensemble “maître” présélectionné d'entités de liaison de données de manière asynchrone cyclique, séquentiellement pour chacune de ces entités de liaison de données. D'autres entités de liaison de données communiquent uniquement si elles sont autorisées et déléguées par ces entités de liaison de données "maîtres". Les communications d'un maître avec d'autres entités de liaison de données peuvent être cycliques ou acycliques avec accès selon un ordre de priorité, ou une combinaison des deux. Ce protocole est un moyen de partager de manière équitable les ressources de communication disponibles. Il comporte des dispositions de fonctionnement synchrone et isochrone.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-3. del: Specifikacija protokola na ravni podatkovnih povezav - Elementi tipa 3 (IEC 61158-4-3:2019)
Nivo podatkovnih povezav omogoča osnovne časovno kritične sporočilne komunikacije med napravami v avtomatizacijskem okolju. Ta protokol omogoča komunikacijske priložnosti za predhodno izbrano »glavno« podmnožico entitet podatkovnih povezav na cikličen asinhroni način, zaporedno za vsako izmed teh entitet podatkovnih povezav. Druge entitete komunicirajo samo na način, ki ga dovolijo in določijo glavne entitete podatkovnih povezav. Za določeno glavno entiteto je lahko njena komunikacija z drugimi entitetami podatkovnih povezav ciklična ali aciklična s prednostnim dostopom ali kombinacija obeh. Ta protokol omogoča sredstvo za razdeljevanje razpoložljivih komunikacijskih virov na pošten način. V njem so določila za časovno sinhronizacijo in za izohrono delovanje.
