This British Standard is a direct transposition of a European Standard produced under the direction of CENELEC TC205, Home and Building Electronic Systems, and represents a majority view of the subject at the time that the text of the standard was sent for bal

Prospective users of this standard are therefore urged to enquire as to the current state of standardization in CENE

User process, see EN 50090-2-
29、1, 3.2.9. 3.1.2 Definitions from EN 27498 Open systems interconnection (OSI) user element 3.2 Additional definitions 3.2.1 data set A data structure corresponding to well defined types of information. 3.2.2 HBES-function A set of operations performed on data set(s). NOTE. If the context makes it cle
30、ar that a function is an HBES-function, the HBES can be omitted. 4 Application structure 4.1 Overview As described in EN 50090-2-1 the application process is divided in two main parts: the user process (see EN 50090-3-2) and the application layer (see ENV 50090-3-3). Because the HBES device applicat
31、ion process is partly embedded in the OSI environment and partly outside it, a distinction has to be made between OSI and non OSI related parts. 4.2 Application objects The application process consists of application objects. Application objects are data sets with their corresponding HBES-functions.
32、 Application objects located in the user process are called user objects. Application objects located in the user element are called communication objects. They connect the user process to the communication part. Figure 1 shows the above mentioned structure.Page 4 EN 50090-3-1 : 1994 BSI 1996 E Figu
33、re 2. Possible information flow Figure 2 shows some possible relationships between these objects. The data sets and HBES functions are described in EN 50090-3-2 (User process) and the communication objects in ENV 50090-3-3 (Application Layer). The application objects are the means for describing app
34、lications. An application is modelled using one or several application objects. Values inside data sets may represent local physical inputs, outputs and internal states, handled by the application. These values may also correspond to information transmitted over the HBES. Values may also correspond
35、to some kind of configuration set by a human user, by software means or to information reported to this human user. The user process performs operations on data sets by means of the corresponding HBES-functions. NOTE. The standards EN 50090-3-1, EN 50090-3-2 and ENV 50090-3-3 are closely related to
