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.
