DESCRIPTION

BS EN 14908-2:2014


This standard BS EN 14908-2:2014 Open Data Communication in Building Automation, Controls and Building Management. Control Network Protocol is classified in these ICS categories:
  • 91.040.01 Buildings in general
  • 97.120 Automatic controls for household use
  • 35.240.67 IT applications in building and construction industry
  • 91.140.01 Installations in buildings in general

This European Standard specifies the control network protocol (CNP) free-topology twisted-pair channel for networked control systems in commercial Building Automation, Controls and Building Management and is used in conjunction with EN 14908-1:2014. The channel supports communication at 78,125 kbit/s between multiple nodes, each of which consists of a transceiver, a protocol processor, an application processor, a power supply, and application electronics.

This European Standard covers the complete physical layer (OSI Layer 1), including the interface to the Media Access Control (MAC) sub-layer and the interface to the medium. Parameters that are controlled by other layers but control the operation of the physical layer are also specified.
