This ability is

24、provided without additional equipment (like translators or gateways). NOTE Media couplers are needed if different media are used in an installation. The market requires Interworking for a multi-vendor approach, this is, products from different manufacturers can interwork in a certain application seg

25、ment or domain as well as across different applications (cross discipline Interworking). Such an Interworking is only possible if a set of requirements is complied with as defined in an Interworking model. For this, Functional Blocks need to be defined, which in turn specify Datapoints and the commu

26、nication mechanisms to be used. Such a set of requirements is referred to as “Application Interworking Specifications“ (AIS). AIS allow Interworking independent of the implementation by a manufacturer. Besides the advantages for the user (multi-vendor offer) Interworking also allows a broad OEM mark

27、et and easy market access for niche-products providers. Furthermore Interworking allows the establishment of a common market infrastructure (i.e. common configuration tool, training, etc.) BS EN 50090-3-3:2009EN 50090-3-3:2009 - 6 - 1 Scope This European Standard gives general guidelines and recomme

28、ndations to ensure interworking between HBES devices made by different manufacturers. It also contains design guidelines for the design of Functional Blocks and new datapoint types, the building blocks of HBES interworking. In this way, the standard can be used as a basis to design application speci

29、fications relative to an Application Domain. If designed and supported by a large group of manufacturers, such application specifications will ensure to end customers a high degree of interoperability between products based on the HBES Communication System of different manufacturers. This European S

30、tandard is used as a product family standard. It is not intended to be used as a stand-alone standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、 Identifier OEM Original Equipment Manufacturer 4 HBES Interworking model HBES Interworking can be applied in many application domains. Each Application Domain can encompass one or more Applications. Application Application Domain Figure 1 - The HBES Interworking Model An Application Domain can cont

36、ain one or more Applications The Application Modelling or the process of analysing, deciding on the solution and specifying the model for such an Application needs to be agreed upon amongst manufacturers in Application Specification Groups. BS EN 50090-3-3:2009EN 50090-3-3:2009 - 8 - Applications sh

37、all not be defined in terms of products, but analysed and split up into Functional Blocks, which communicate with one another. The term Distributed Application indicates this approach: the total functionality of an Application is spread over a number of Functional Blocks implemented in various devic

38、es in the network. A Functional Block transports its data over the bus via one or more Datapoints (these are Inputs, Outputs, Parameters and Diagnostic Data). A Functional Block thus describes the standard specification of the chosen solution for one given task of an application. These Datapoints an

39、d their described functionality are implemented by the product developer. The following picture shows the Interworking model as defined so far.

45、 handling of its Datapoints and physical inputs and outputs (e.g. a state machine of a dimming actuator). A Datapoint is any interface over which data in the Functional Block can be set or received and/or transmitted (for its run-time operation). Every Functional Block may have one or more such Data

46、points. From the communication point of view, 4 classes of Datapoints can be distinguished (for more information see 5.3.3): NOTE These classes of Datapoints are defined in EN 50090-4-2, EN 50090-4-1 and EN 50090-3-2: Group Object Datapoint Interface Object Property Datapoint Polling Value Datapoint

Output: the value resulting from the process of the Functional Block and to be provided to at least one other Functional Block. Parameter: a value that controls the process of handling the Input(s)

49、and generating the values of the Output(s). This access type is typically non-volatile or saved at reset. It is usually set by management functions. Diagnostic Data: a value that represents the local or internal status information of a Functional Block.
