DIN EN 14908-3:2014-08 EN 14908-3: 2014 (E) 4 Introduction This part
34、of EN 14908 specifies the Control Network Power Line (PL) Channel and serves as a companion document to EN 14908-1:2014. Its purpose is to present the information necessary for the development of a PL physical network and nodes to communicate and share information over that network. This is one of a
35、 series of documents covering the various media that comprise the CNP standard. This part of EN 14908 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access Control (MAC) Sub-Layer and the interface to the medium. It includes parameters specific to the PL chann
36、el type, even though the parameters may be controlled at an OSI layer other than layer 1. This part of EN 14908 also provides a set of guideline physical and electrical specifications for the power line environment as an aid in developing products for that environment. This part of EN 14908 has been
37、 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 communication capabilities. This part of EN 14908 is used by all involved in design, manufacture, engineering, i
38、nstallation and commissioning activities. The CNP specification model is based on the OSI 7-layer model Reference Model. There are also important extensions to the OSI Reference Model. Figure 1 shows the scope of this specification in reference to the entire CNP model. In this European Standard, onl
39、y the parts of the model relevant to power line communication are specified. Anything outside this boundary is covered in other parts of the standard. Similar specifications exist for other CNP media. Figure 1 Relationship of CNP 3 specification to the CNP 1 specification DIN EN 14908-3:2014-08 EN 1
40、4908-3: 2014 (E) 5 1 Scope This European Standard specifies all the information necessary to facilitate the exchange of data and control information over the power line medium for networked control systems in commercial Building Automation, Controls and Building Management. This European Standard es
41、tablishes 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 (defined by users) to coexist. Certain aspects of this standard are defined i
42、n other documents. These documents are referenced where relevant. In the case where a referenced standard conflicts with this European Standard, this part of EN 14908 will prevail. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and ar
