IEC 61158-6-10:2023

Industrial communication networks - Fieldbus specifications - Part 6-10: Application layer protocol specification - Type 10 elements

IEC 61158-6-10:2023 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 10 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 a 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 6-10: Spécification du protocole de la couche application - Éléments de type 10

L'IEC 61158-6-10:2023 donne les éléments communs visant à assurer les communications de messagerie de base à temps critique et à temps non critique entre les programmes d’application d’un environnement d’automatisation et d’un matériel spécifique au bus de terrain de type 10. Le terme "prioritaire" est utilisé pour traduire la présence d’une fenêtre temporelle à l’intérieur de laquelle une ou plusieurs actions spécifiées doivent être terminées avec un niveau de certitude défini. Tout manquement à réaliser ces actions dans la fenêtre de temps prévue risque de provoquer la défaillance des applications qui les demandent, avec le risque de mettre en danger l’équipement, l’usine, voire les personnes.
