Open Data Communication in Building Automation, Controls and Building Management - Control Network Protocol - Part 3: Power Line Channel Specification

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 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 (defined by users) to coexist.
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 European Standard, this part of EN 14908 will prevail.

3 Foreword This document (EN 14908-3:2014) has been prepared by Technical Committee CEN/TC 247 “Building Automation, 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of an identical text or by endorsement, at the latest by October 2014 and conflicting national standards shall be withdrawn at the latest by October 2014. 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 for identifying any or all such patent rights. This document supersedes EN 14908-3:2006. This European 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 European Standard covers the data communications used for management, automation/control and field functions. EN 14908-3 is part of a series of European Standards under the general title 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. 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, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 14908-3:2014

EN 14908-3: 2014 (E) 4 Introduction This part 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 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 channel 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 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, installation 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, only 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.

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 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 (defined by users) to coexist. 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 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 are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 14908-3: 2014 (E) 6 4 General description 4.1 Electrical safety This clause gives several recommendations related to safety concerns with respect to this European Standard. This discussion is not complete, nor does it address all possible safety issues. The designer is urged to consult, among other things, the relevant local and national electrical codes for the country of intended use. Local codes may supplement national electrical codes and impose additional safety related requirements. Products conforming to this European Standard shall be designed, constructed, assembled, tested and installed following recognised safety provisions appropriate to products covered by the standard. Power line network cables are subject to at least five direct electrical safety hazards during their use: • high-energy transients coupled into the power line network from external environmental sources; • possible differences between safety grounds to which network components are connected; • possible high voltages on neutral or ground wiring; • possible open safety grounds; • high short-circuit current levels available at interface. These electrical safety hazards should be alleviated for the network to perform properly. In addition to provisions for properly handling these faults in an operational system, special measures should be taken to maintain the intended safety features during changes of an existing network.
