Industrial communication networks - Fieldbus specifications - Part 3-24: Data-link layer service definition - Type 24 elements
IEC 61158-3-24:2023 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.This document defines in an abstract way the externally visible service provided by the Type 24 fieldbus data-link layer in terms ofthe primitive actions and events of the service;the interrelationship between these actions and events, and their valid sequences;the parameters associated with each primitive action and event, and the form which they take.

IEC 61158-3-24:2014 defines the services provided to the Type 24 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model.
ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
