36、-15 IEC:2010(E) 7 INTRODUCTION This part of IEC 61158 is one of a series produced to facilitate the interconnection of automation system components. 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 servi
37、ce is provided by the application protocol making use of the services available from the data-link or other immediately lower layer. This standard defines the application service characteristics that fieldbus applications and/or system management may exploit. Throughout the set of fieldbus standards
38、, the term “service” refers to the abstract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the application layer service defined in this standard is a conceptual architectural service, independent of administrative and implementation divisions
39、. BS EN 61158-5-15:2012 8 61158-5-15 IEC:2010(E) INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 5-15: Application layer service definition Type 15 elements 1 Scope 1.1 Overview In network communications, as in many fields of engineering, it is a fact that “one size does not fit all.”
40、 Engineering design is about making the right set of trade-offs, and these trade-offs must balance conflicting requirements such as simplicity, generality, ease of use, richness of features, performance, memory size and usage, scalability, determinism, and robustness. These trade-offs must be made i
41、n light of the types of information flow (e.g. periodic, one-to-many, request-reply, events), and the constraints imposed by the application and execution platforms. The Type 15 fieldbus provides two major communication mechanisms that complement each others to satisfy communication requirements in
42、the field of automation: the Client/Server and the Publish/Subscribe paradigms. They can be used concurrently on the same device. Type 15 Client/Server operates in a Client/Server relationship. Its application layer service definitions and protocol specifications are independent of the underlying la
43、yers, and have been implemented on a variety of stacks and communication media, including EIA/TIA-232, EIA/TIA-422, EIA/TIA-425, HDLC (ISO 13239), fiber, TCP/IP, Wireless LANs and Radios. Type 15 Publish/Subscribe operates in a Publish/Subscribe relationship. Its application layer service definition
44、s and protocol specifications are independent of the underlying layers and can be configured to provide reliable behavior and support determinism. The most common stack is UDP/IP. The fieldbus application layer (FAL) provides user programs with a means to access the fieldbus communication environmen
45、t. In this respect, the FAL can be viewed as a “window between corresponding application programs.” This part of IEC 61158 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific t
46、o Type 15 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 of certainty. Failure to complete specified actions within the time window risks failure of the application
47、s requesting the actions, with attendant risk to equipment, plant and possibly human life. This part of IEC 61158 defines in an abstract way the externally visible service provided by the Type 15 fieldbus application layer in terms of a) an abstract model for defining application resources (objects)
48、 capable of being manipulated by users via the use of the FAL service, b) the primitive actions and events of the service; c) the parameters associated with each primitive action and event, and the form which they take; and d) the interrelationship between these actions and events, and their valid s
49、equences. BS EN 61158-5-15:201261158-5-15 IEC:2010(E) 9 The purpose of this part of IEC 61158 is to define the services provided to a) the FAL user at the boundary between the user and the Application Layer of the Fieldbus Reference Model, and b) Systems Management at the boundary between the Application Layer and Systems Management of the Fieldbus Reference Model.
