What is BS EN 61158-5-11 - Type 11 application layer service definition about?
BS EN 61158-5-11 is part of a series produced to facilitate the interconnection of automation system components. BS EN 61158-5-11 is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC/TR 61158-1 . BS EN 61158-5-11 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 11 fieldbus. BS EN 61158-5-11 defines in an abstract way the externally visible service provided by the different types of fieldbus application layer in terms of:
An abstract model for defining application resources (objects) capable of being manipulated by users via the use of the FAL service The primitive actions and events of the service The parameters associated with each primitive action and event, and the form which they take The interrelationship between these actions and events, and their valid sequences
