IEC 61158-4-19:2014

Industrial communication networks - Fieldbus specifications - Part 4-19: Data-link layer protocol specification - Type 19 elements

IEC 61158-4-19:2014 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:
- introducing connections based on a producer-consumer model;
- introducing additional mechanisms to realize features such as timestamping and oversampling;
- improving the hotplug and redundancy features;
- improving the phase switching and the error handling.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 4-19: Spécification du protocole de la couche liaison de données - Eléments de type 19

L'IEC 61158-4-19:2014 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 modifications principales sont:
- introduction de connexions établies sur un modèle producteur-consommateur;
- introduction de mécanismes supplémentaires destinés à réaliser des fonctionnalités telles que l'horodatage et le sur-échantillonnage;
- amélioration des caractéristiques de connexion à chaud et de redondance;
- amélioration de la commutation des phases et de la gestion des erreurs.
