This European Standard shall be
21、 given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. This standard is part of a series of standards for open data transmission in bui
22、lding automation, control and in building management systems. The content of this standard covers the data communications used for management, automation/control and field functions. The EN 14908-5 is part of a series of European Standards under the title, Open Data Communication in Building Automat
23、ion, Controls and Building Management Control Network Protocol (CNP), which comprises the following parts: Part 1: Protocol Stack Part 2: Twisted Pair Communication Part 3: Power Line Channel Specification Part 4: IP Communication Part 5: Implementation Part 6: Application elements Attention is draw

27、ontrol Network Protocol (CNP) Specification: EN 14908-1:2005. The CNP specification model is based on the ISO Open Systems Interconnection Reference Model. There are also important extensions to the 7-layer OSI Reference Model. Figure 1 shows the scope of this specification in reference to the CNP a
28、nd companion specifications for handling various data-transport media at the lower ISO protocol layers. A dashed line is used to show that the scope of this document is not treated as redundant, compared with other specifications covering their respective layers but as a complement to those specific
29、ations in implementing them in an interoperable fashion. In this document, the guidelines for implementing a device based on CNP are specified to increase the ability for devices to interoperate regardless of the installer or manufacturer of the devices. Anything outside this boundary is covered in
30、other parts of the standard. Similar specifications exist for CNP data-transport media. This standard has been prepared to provide mechanisms through which various vendors of building automation, control, and of building-management systems, may exchange information in a standardised way. It defines
31、communication and internal-documentation requirements. This standard is contributing to the general European policy for energy savings particularly in the field of the “Energy Performance of Building Directive” and the Construction Products Directive (ER No. 6 “Energy Economy and Heat Retention”).

33、n commercial building automation, control, and building management may exchange information in a standardised way. This specification contains all the information necessary to facilitate the exchange of data and control information in an interoperable fashion using EN 14908-1 and its associated data
34、-transport media specifications. This specification establishes a minimal set of rules for compliance. It does not rule-out extended services to be provided, given that the rules are adhered-to within the system. It is the intention of the standard to permit extended services to coexist and defines
35、the bounds in which those services function, including the format for internal device-documentation of those services. Services outside purvey of this specification so long as they are adherents of the system are permitted but will not necessarily be interoperable with any other devices and shall no
36、t be essential for the functioning of the device. Certain aspects of this standard are defined in other documents. These documents are referenced where relevant. In the case where a referenced standard conflicts with this document, this document will prevail. 2 Normative references The following ref
