IEC 61158-5-4:2023

Industrial communication networks - Fieldbus specifications - Part 5-4: Application layer service definition - Type 4 elements

IEC 61158-5-4:2023 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 4 fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 5-4: Définition des services de la couche application - Éléments de type 4

L'IEC 61158-5-4:2023 fournit des éléments communs pour les communications prioritaires ou non entre des programmes d’application dans un environnement et avec un matériel d’automatisation spécifiques aux bus de terrain de type 4. Le terme "prioritaire" signale l’existence d’une fenêtre temporelle dans laquelle une ou plusieurs actions spécifiées doivent être réalisées, avec un niveau de certitude défini. Si les actions spécifiées ne sont pas réalisées dans la fenêtre temporelle, les applications demandant les actions risquent de connaître une défaillance, avec les risques que cela comporte pour les équipements, les installations et éventuellement la vie humaine.
