BS EN 14908-1:2014

This standard BS EN 14908-1:2014 Open Data Communication in Building Automation, Controls and Building Management. Control Network Protocol is classified in these ICS categories:

• 97.120 Automatic controls for household use
• 35.240.67 IT applications in building and construction industry
• 91.040.01 Buildings in general
• 91.140.01 Installations in buildings in general

This European Standard applies to a communication protocol for networked control systems in commercial Building Automation, Controls and Building Management. The protocol provides peer-topeer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. This specification describes services in layers 2 to 7. In the layer 2 (data link layer) specification, it also describes the MAC sub-layer interface to the physical layer. The physical layer provides a choice of transmission media. The interface described in this specification supports multiple transmission media at the physical layer. In the layer 7 specification, it includes a description of the types of messages used by applications to exchange application and network management data.
