Industrial communication networks - Fieldbus specifications - Part 4 -19: Data-link layer protocol specification - Type 19 elements (IEC 61158-4-19:2019)

The data-link layer provides basic time-critical messaging communications between devices in an automation environment. This protocol provides communication opportunities to all participating data- link entities a) in a synchronously-starting cyclic manner, according to a pre-established schedule, and b) 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.

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 (IEC 61158-4-19:2019)

IEC 61158-4-19:2019 La couche liaison de données assure les communications de messagerie prioritaires de base entre les appareils d’un environnement d’automatisation.
Ce protocole offre à toutes les entités de liaison de données participantes
a) des opportunités de communication cyclique à démarrage synchrone, selon un ordre préétabli, et
b) de manière asynchrone cyclique ou acyclique, tel que requis à chaque cycle par chacune de ces entités de liaison de données.
Ainsi, ce protocole peut être caractérisé comme un protocole qui offre un accès cyclique et acyclique asynchrone, mais avec un redémarrage synchrone de chaque cycle.

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 asinhroni 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.
