Industrial communication networks - Fieldbus specifications - Part 4-24: Data-link layer protocol specification - Type 24 elements

IEC 61158-4-24:2019 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 second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision with the following technical changes: •patent declaration in the Introduction; •corrections on transmission sequence of fixed-width time slot type in 4.3.2; •technical extension for band sharing between I/O data exchange and message communication; •spelling and grammar

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 4-24: Spécification du protocole de la couche liaison de données - Éléments de type 24

L'IEC-61158-4-24:2019 spécifie a) les procédures de transfert en temps opportun des données et des informations de commande entre une entité utilisateur de liaison de données et une entité utilisateur homologue et, parmi les entités de liaison de données formant le fournisseur de services distribués de liaison de données; b) les procédures pour donner des opportunités de communication à toutes les entités DL participantes, séquentiellement et de manière cyclique pour le transfert déterministe et synchronisé à intervalles cycliques pouvant aller jusqu'à 64 ms; c) les procédures pour donner les opportunités de communication disponibles pour la transmission de données prioritaires ainsi que pour la transmission de données non prioritaires, sans nuire à la transmission de données prioritaire; d) les procédures pour donner des opportunités de communication cyclique et acyclique pour la transmission de données prioritaires avec accès hiérarchisés; e) les procédures pour donner des opportunités de communication selon le contrôle d'accès au support physique normalisé par l'ISO/IEC/IEEE 8802 3, avec des dispositions pour les nœuds à ajouter ou à retirer lors du fonctionnement normal; f) la structure des DLPDU de bus de terrain utilisées par le protocole du présent document pour le transfert des données et des informations de commande, et leur représentation sous forme d'unités de données d'interface physique.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-24. del: Specifikacija protokola na ravni podatkovnih povezav - Elementi tipa 24 (IEC 61158-4-24:2019)

Nivo podatkovnih povezav omogoča osnovne časovno kritične sporočilne komunikacije med napravami v avtomatizacijskem okolju. Ta protokol omogoča komunikacijske priložnosti vsem sodelujočim entitetam podatkovnih povezav a) na cikličen način s sinhronim začetkom v skladu z vnaprej določenim razporedom ali b) na necikličen način, kot zahtevajo posamezne entitete podatkovnih povezav. Tako lahko ta protokol opredelimo kot protokol, ki asinhrono omogoča cikličen in acikličen dostop s sinhronim ponovnim zagonom vsakega cikla.
