23、mittee CEN/TC 247 “Building automation and controls and building management”, the secretariat of which is held by SNV. This European Standard shall be 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

24、 national standards shall be withdrawn at the latest by October 2009.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 building automation, control and in building management systems. The content of this standard covers the data communications used for management, automat

25、ion/control and field functions. The EN 14908-5 is part of a series of European Standards under the title, Open Data Communication in Building Automation, Controls and Building Management Control Network Protocol (CNP), which comprises the following parts: Part 1: Protocol Stack Part 2: Twisted Pair

26、 Communication Part 3: Power Line Channel Specification Part 4: IP Communication Part 5: Implementation Part 6: Application elements Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible

27、for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germ

BS EN 14908-5:2009EN 14908-5:2009 (E) 6 Introduction This document specifies the Layered Impleme

29、ntation Guidelines (LIG) for the Control 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 speci

30、fication in reference to the CNP and 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

31、 as a complement to those specifications 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 ou

32、tside this boundary is covered in 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

33、in a standardised way. It defines 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 “Ener

34、gy Economy and Heat Retention”). Figure 1 Scope of this specification BS EN 14908-5:2009EN 14908-5:2009 (E) 7 1 Scope This specification provides mechanisms through which various vendors of networked control systems in commercial building automation, control, and building management may exchange inf

35、ormation 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-transport media specifications. This specification establishes a minimal set of ru

36、les 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 the bounds in which those services function, including the format for internal devi

37、ce-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 not be essential for the functioning of the device. Certain aspects of this standard

38、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 referenced documents are indispensable for the application of this document.
