4、DateComments National foreword This Draft for Development is the English language version of ENV 13154-1:2000. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because further experienc
5、e of its application is required before publication as a European Standard. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience
6、 can be reported to the European organization responsible for its conversion into a European Standard. A review of this publication will be intiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its three-year life. The commenc
7、ement of the review period will be notified by an announcement in Update Standards. According to the replies recieved by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the prestandard or to wit
8、hdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee RHE/16/1, Control and management systems for building purposes, at 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the te
9、xt. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled Int
10、ernational Standards Correspondence Index, or by using the Find facility of the BSI Standards Electronic Catalogue. Summary of pages This document comprises a front cover, an inside front cover, the ENV title page, pages 2 to 74, an inside back cover and a back cover. The BSI copyright notice displa

32、ion for HVAC applications. Each of these networks has its own application layer protocol and services. Superordinate systems, which have to deal with this multitude of protocols, as well as field level end units and field level gateways, would benefit from a common set of objects and abstract servic
33、es, mapped onto this variety of communication protocols. This prestandard defines an object set which is independant of any communications protocol and is to be used for the implementation of application interfaces and gateway structures within building automation products. It is intended to be read
34、 by professional software and system design engineers. Licensed Copy: London South Bank University, London South Bank University, Tue Dec 12 05:07:35 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 6 ENV 13154-1:2000 1 Scope This prestandard defines FLN-objects and FLN-services to be used on a field
35、 level for system neutral exchange of data for HVAC applications. This prestandard defines the semantics of the objects and the abstract services applicable to them and it defines an optional syntax to be used to exchange data with a communication front-end unit. The syntax of the object data on the
36、 underlying communication (bus) protocol is not within the scope of this prestandard. In particular, this prestandard provides a set of objects and services which are : ? to be used by the application programmer as a unique logical interface independent of the underlying communication system. A form
37、al application programme interface may subsequently be defined in an amendment to this prestandard if TC247 considers this appropriate. ? to be used in an interface between the HBES device and a portable communication front-end, defined as level D or as a process-interface in EN 50090-2-1 ? to be in
38、corporated and mapped by the providers of the field level protocols ? the objects to be incorporated in the protocol providers set of objects and to be encoded in APDUs of the respective protocol ? the services to be mapped by the protocol providers onto appropriate services of their respective prot

47、C/S modelThe c/s (client/server) model relies upon one (or multiple) client(s), requesting a distinct service from a server-application. The server- application carries out the task according to the request and, usually, returns a result to the client(s) P/C modelIn the p/c (producer / consumer) mod
48、el, the producer of information offers its data to whoever it may concern. In contrast to the c/s model, there is no explicit relationship between a producer and the potential consumers of its data. Semantics and SyntaxSemantics is in linguistics, the study of meanings. In computer science, the term
49、 is frequently used to differentiate the meaning of an instruction from its format. The format, which covers the spelling of language components and the rules controlling how components are combined, is called the languages syntax. For example, if you misspell a command, it is a syntax error. If, on the other hand, you enter a legal command that does not make any sense in the current context, it is a semantic error.Source: http:/ SuperordinateA superordinate BA-system or BA-controller is a system or controller residing in a higher level of t
