What is BS EN 61158-6-7 - Type 7 application layer protocol specification about?

BS EN 61158-6-7 is part of a series produced to facilitate the interconnection of automation system components. BS EN 61158-6-15 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 61158-6-7 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 7 fieldbus. BS EN 61158-6-7 specifies interactions between remote applications and defines the externally visible behaviour provided by the Type 7 fieldbus application layer in terms of:

The formal abstract syntax defining the application layer protocol data units conveyed between communicating application entities The transfer syntax defining encoding rules that are applied to the application layer protocol data units The application context state machine defining the application service behaviour visible between communicating application entities The application relationship state machines defining the communication behaviour visible between communicating application entities
