1   Scope This European Standard defines the integration of KNX protocol implementations on top of Internet Protocol ( IP ) networks, called KNXnet/ IP . It describes a standard protocol for KNX devices connected to an IP network, called KNXnet/IP devices . The IP network acts as a fast (compared to KNX transmission speed) backbone in KNX installations. Widespread deployment of data networks using the Internet Protocol ( IP ) presents an opportunity to expand building control communication beyond the local KNX control bus, providing:

— 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).

A KNXnet/ IP system contains at least these elements:
