Industrial communication networks - Fieldbus specifications - Part 4-18: Data-link layer protocol specification - Type 18 elements

IEC 61158-3-18:2010(E) 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; procedures for giving communications opportunities to all participating DL entities, sequentially and in a cyclic manner for deterministic and synchronized transfer at cyclic intervals up to one millisecond; procedures for giving communication opportunities available for time-critical data transmission together with non-time-critical data transmission without prejudice to the time-critical data transmission; procedures for giving cyclic and acyclic communication opportunities for time-critical data transmission with prioritized access; procedures for giving communication opportunities based on standard ISO/IEC 8802-3 medium access control, with provisions for nodes to be added or removed during normal operation; 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 2007 and constitutes a technical revision. The main changes with respect to the previous edition are: - Editorial improvements and Addition of cyclic data segmenting.

Réseaux de communication industriels - Spécifications de bus de terrain - Partie 4-18: Spécification du protocole de couche de liaison de données - Eléments de type 18

La CEI 61158-4-18:2010 spécifie un protocole qui offre à toutes les entités de liaison de données participantes des opportunités de communiquer de manière cyclique à démarrage synchrone, selon un ordre préétabli, et de manière asynchrone cyclique ou acyclique, tel que requis par chaque cycle de chacune de ces entités de liaison de données. Les procédures décrites s'appliquent aux instances de communication entre des systèmes qui prennent en charge des services de communications à contrainte de temps dans la couche de liaison de données des modèles de référence OSI ou de bus de terrain, et qui peuvent être connectés dans un environnement d'interconnexion de systèmes ouverts. Les profils sont un moyen simple à plusieurs attributs de récapituler les capacités d'une mise en uvre, et donc son applicabilité en fonction des différents besoins de communications à contrainte de temps. Cette seconde édition annule et remplace la première édition parue en 2007. Elle constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont: Améliorations rédactionnelles et Ajout d'une segmentation des données cycliques. La présente version bilingue (2012-08) correspond à la version anglaise monolingue publiée en 2010-08.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-18. del: Specifikacija protokola na nivoju podatkovnih povezav - Elementi tipa 18 (IEC 61158-4-18:2010)

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 in b) na cikličen ali necikličen asinhron način, kot posamezne entitete podatkovnih povezav zahtevajo v vsakem ciklu. Tako lahko ta protokol opredelimo kot protokol, ki asinhrono omogoča cikličen in acikličen dostop s sinhronim ponovnim zagonom vsakega cikla.
