Industrial communication networks - Fielbus specifications - Part 4-12: Data-link layer protocol specification - Type 12 elements
IEC 61158-4-12:2007 It 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, and in a cyclic or acyclic asynchronous manner, as requested each cycle by each of those data-link entities. Thus this protocol can be characterized as one which provides cyclic and acyclic access asynchronously but with a synchronous restart of each cycle. It includes the following significant changes with respect to 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.
Réseaux de communication industriels - Specification des bus de terrain - Partie 4-12: Spécification du protocole de la couche liaison de données - Eléments de type 12
L'IEC 61158-4-12:2007 décrit le protocole qui offre des opportunités de communication à toutes les entités de liaison de données participantes: de manière cyclique et synchrone, 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 ses parties d'accompagnement de la sous-série CEI 61158-4 annulent et remplacent la CEI 61158-4:2003. Elle constitue une addition technique, qui remplace également la CEI/PAS 62407, publiée en 2005. Cette édition de la CEI 61158-4 inclut les modifications majeures suivantes par rapport à l'édition précédente: suppression du précédent bus de terrain de Type 6 et de la référence à une couche de liaison de données de bus de terrain de Type 5, en raison du manque d'adéquation au marché; ajout de nouveaux types de bus de terrain; division de cette partie en parties multiples numérotées -4 1, -4 2, , -4-19. La présente version bilingue (2014-06) correspond à la version anglaise monolingue publiée en 2007-12.
