It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC 61158-1
41、. The application protocol provides the application service by making use of the services available from the data-link or other immediately lower layer. The primary aim of this standard is to provide a set of rules for communication expressed in terms of the procedures to be carried out by peer appl
42、ication entities (AEs) at the time of communication. These rules for communication are intended to provide a sound basis for development in order to serve a variety of purposes: as a guide for implementers and designers; for use in the testing and procurement of equipment; as part of an agreement fo
43、r the admittance of systems into the open systems environment; as a refinement to the understanding of time-critical communications within OSI. This standard is concerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standar
44、d together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination.

45、tocol specification Type-24 Elements 1 Scope General 1.1The Fieldbus Application Layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a “window between corresponding application programs.” This standard provides c
46、ommon elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 24 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified a
47、ctions 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 standard defines in an abstract way t
48、he externally visible behavior provided by the Type 24 fieldbus application layer in terms of a) the abstract syntax defining the application layer protocol data units conveyed between communicating application entities, b) the transfer syntax defining the application layer protocol data units conve
49、yed between communicating application entities, c) the application context state machines defining the application service behavior visibly between communicating application entities, and d) the application relationship state machines defining the communication behavior visibly between communicating application entities. The purpose of this standard is t
