IEC 61158-3-4:2023 provides common elements for basic time-critical messaging communications between devices in an automation environment. 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.全文を表示する
This document defines in an abstract way the externally visible services provided by the Type 4 fieldbus data-link layer in terms of
the primitive actions and events of the services;
the parameters associated with each primitive action and event, and the form which they take; and
the interrelationship between these actions and events, and their valid sequences.
The purpose of this document is to define the services provided to
the Type 4 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model;
systems management at the boundary between the data-link layer and systems management of the fieldbus reference model.
