IEC 61158-4-19:2007
(Main)Industrial communication networks - Fieldbus specifications - Part 4-19: Data-link layer protocol specification - Type 19 elements
Industrial communication networks - Fieldbus specifications - Part 4-19: Data-link layer protocol specification - Type 19 elements
IEC 61158-4-19:2007 defines the protocol that provides basic time-critical messaging communications between devices in an automation environment. This protocol provides communication opportunities to all participating data-link entities in a synchronously-starting cyclic manner, according to a pre-established schedule, and in a cyclic or acyclic asynchronous manner, as requested each cycle by each of those data-link entities. This first edition and its companion parts of the IEC 61158-4 subseries cancel and replace IEC 61158-4:2003. This part and its companion Type 19 parts also cancel and replace IEC PAS 62410, published in 2005. This edition of IEC 61158-4 includes the following significant changes from the previous edition:
- deletion of the former Type 6 fieldbus, and the placeholder for a Type 5 fieldbus data link layer, for lack of market relevance;
- addition of new types of fieldbuses;
- division of this part into multiple parts numbered -4-1, -4-2, , -4-19. This bilingual version (2014-12) corresponds to the monolingual English version, published in 2007-12.
Réseaux de communication industriels - Spécifications des bus de terrain - Partie 4-19: Spécification des protocoles des couches de liaison de données - Eléments de type 19
L'IEC 61158-4-19:2007 définit la couche liaison de données qui assure les communications de messagerie de base à temps critique entre les appareils d'un environnement d'automatisation. Ce protocole offre des opportunités de communication à toutes les entités de liaison de données participantes de manière cyclique avec un démarrage synchrone, selon une programmation préétablie, et de manière cyclique ou acyclique et asynchrone, comme demandé par chaque cycle de chacune de ces entités de liaison de données. Cette première édition et les autres parties de la sous-série CEI 61158-4 annulent et remplacent la CEI 61158-4:2003. La présente partie et ses parties d'accompagnement de Type 19 annulent et remplacent également la CEI PAS 62410, publiée en 2005. Cette édition de la CEI 61158-4 inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- suppression de l'ancien bus de terrain de type 6, et le réceptacle pour une couche liaison de données de bus terrain de type 5, en raison du manque d'adéquation au marché;
- ajout de nouveaux types de bus de terrain;
- division de la présente partie en plusieurs parties numérotées -4-1, -4-2, , -4-19. La présente version bilingue (2014-12) correspond à la version anglaise monolingue publiée en 2007-12.
