scope:
This specification 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:
- one EIB line with up to 64 (255) EIB devices
OR
one KNX segment (KNX-TP1, KNX-TP0, KNX-RF, KNX-PL110, KNX-PL132),
- a KNX-to-IP network connection device (called KNXnet/IP server),
and typically additional
- software for remote functions residing on e.g. a workstation
(may be iETS, data base application, BACnet Building Management System, browser, ...).
