DIN EN 13321-2:2013-03

This standard is has been developed for the design of new buildings and the retrofit of existing buildings to achieve an acceptable indoor environment as well as practical energy conservation and efficiency. This standard specifies the integration of KNX protocol implementations within the Internet Protocol (IP) named KNXnet/IP. Moreover, it specifies a standard protocol, which is implemented within KNX devices, ETS (Engineering Tool Software) and other implementations to support KNX data exchange over IP networks. In essence, KNXnet/IP provides a general framework, which accommodates several specialised "Service Protocols" in a modular and extendible fashion. The KNXnet/IP standard consists of the following clauses: - clause 1, Overview; - clause 2, Core Specification; - clause 3, Device Management, - clause 4, Tunnelling - clause 5, Routing; - clause 6, Remote Diagnosis and Configuration. Widespread deployment of data networks using the Internet Protocol (IP) presents an opportunity to expand building control communication beyond the local KNX control bus, allowing for the following: - remote configuration; - remote operation (including control and annunciation); - fast interface from LAN to KNX and vice versa; - WAN connection between KNX systems (where an installed KNX system is at least one line).
