適用范圍：This standard provides common elements for basic time-critical and non-time-critical messagingcommunications between application programs in an automation environment and material specificto Type 16 fieldbus. The term “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 ofcertainty. Failure to complete specified actions within the time window risks failure of theapplications requesting the actions, with attendant risk to equipment, plant and possibly human life.This standard define in an abstract way the externally visible service provided by the differentTypes of fieldbus Application Layer in terms of? an abstract model for defining application resources (objects) capable of being manipulated byusers 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;and? the interrelationship between these actions and events, and their valid sequences.The purpose of this standard is to define the services provided to? the FAL user at the boundary between the user and the Application Layer of the FieldbusReference Model, and? Systems Management at the boundary between the Application Layer and Systems Managementof the Fieldbus Reference Model.This standard specifies the structure and services of the IEC fieldbus Application Layer, inconformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI Application LayerStructure (ISO/IEC 9545).The principal objective of this standard is to specify the syntax and behavior of the application layerprotocol that conveys the application layer services defined in IEC 61158-5-16.A secondary objective is to provide migration paths from previously-existing industrialcommunications protocols. It is this latter objective which gives rise to the diversity of protocolsstandardized in subparts of IEC 61158-6.
