IEC 61158-3-14:2010 provides common elements for basic time-critical messaging communications between devices in an automation environment. It defines in an abstract way the externally visible service provided by the Type 14 fieldbus data-link layer in terms of the primitive actions and events of the service; 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.
