42、onents. It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC/TR 61158-1. 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

43、 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 application 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

44、 of purposes: as a guide for implementors and designers; for use in the testing and procurement of equipment; as part of an agreement for the admittance of systems into the open systems environment; as a refinement to the understanding of time-critical communications within OSI. This standard is con

45、cerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination. BS EN 6

In this respect,

47、 the FAL can be viewed as a “window between corresponding application programs.” This standard 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. The term

48、“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, wit

49、h attendant risk to equipment, plant and possibly human life. This standard specifies interactions between remote applications and defines the externally visible behavior provided by the Type 7 fieldbus application layer in terms of a) the formal abstract syntax defining the application layer protoco
