Industrial communication networks - Fieldbus specifications - Part 4-2: Data-link layer protocol specification - Type 2 elements
IEC 61158-4-2:2023 is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the "three-layer" fieldbus reference model described in IEC 61158‑1. The data-link protocol provides the data-link service by making use of the services available from the physical layer. The primary aim of this document is to provide a set of rules for communication expressed in terms of the procedures to be carried out by peer data-link entities (DLEs) at the time of communication. These rules for communication are intended to provide a sound basis for development in order to serve a variety of purposes: - as a guide for implementers and designers; - for use in the testing and procurement of equipment; - as part of an agreement for the admittance of systems into the open systems environment; - as a refinement to the understanding of time-critical communications within OSI.

L'IEC 61158-4-2:2023 appartient à la série de normes visant à faciliter l’interconnexion des composants du système d’automatisation. Elle est liée aux autres normes de la série telle que définie par le modèle de référence de bus de terrain "à trois couches" décrit dans l’IEC 61158‑1. Le protocole de liaison de données assure un service de liaison de données en s’appuyant sur les services offerts par la couche physique. Le présent document a pour principal objet de préciser un ensemble de règles de communication, exprimées sous la forme de procédures que doivent réaliser des entités de liaison de données homologues (DLE) au moment de la communication. Ces règles de communication ont pour vocation de fournir une base de développement stable visant à atteindre différents objectifs: guider les implémenteurs et les concepteurs; réaliser les essais et acquérir l’équipement; dans un accord d’intégration des systèmes dans l’environnement de systèmes ouverts; dans le cadre d’une meilleure compréhension des communications prioritaires au sein de l’OSI.
Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-2. del: Specifikacija protokola na ravni podatkovne povezave - Elementi tipa 2 (IEC 61158-4-2:2023)
Standard IEC 61158-4-2:2023 spada v skupino standardov, namenjenih za lažje medsebojno povezovanje sestavnih delov avtomatizacijskega sistema. Povezan je z drugimi standardi v sklopu, kot je opredeljeno z referenčnim modelom procesnih vodil »s tremi ravnmi« iz standarda IEC 61158-1.
Protokol podatkovnih povezav zagotavlja opravilo podatkovne povezave z uporabo opravil, ki so na voljo na fizični ravni. Primarni cilj tega dokumenta je zagotoviti nabor pravil za komunikacijo, izraženih v smislu postopkov, ki jih morajo izvesti entitete vrstnikov podatkovne povezave (DLE) v času komunikacije. Ta pravila za komunikacijo so namenjena zagotavljanju trdne podlage za razvoj za različne namene:
– kot vodilo za izvajalce in projektante;
– za uporabo pri preskušanju in nabavi opreme;
– kot del dogovora za sprejem sistemov v okolje odprtih sistemov;
– za boljše razumevanje časovno kritičnih komunikacij znotraj OSI.
