This document contains all the information necessary to read and interpret the format of data and control information that is used by EN 14908 5. It also defines the device interface for a device as specified, which is necessary to exchange data between various devices from different manufacturers.

The purpose of this document is to define data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems and to define, in addition, an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

In this European Standard the IP channel will be defined in such a way to allow it to be used like any other CNP channel.
In the above diagram, the IP network can be considered to be one or more IP channels. This European Standard covers only how CNP packets are transported over IP channels. It does not cover how CNP packets are routed between standard CNP channels and IP channels. This specification is not intended to cover the lower layers (physical, MAC and link layers) of either standard CNP or IP channels.

-   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 data base application, BACnet Building Management System, browser, etc.).
Figure 1 shows a typical scenario where a KNXnet/IP client (e.g. running ETS) accesses multiple KNX installed systems or KNX subnetworks via an IP network. The KNXnet/IP client may access one or more KNXnet/IP servers at a time. For subnetwork, routing server-to-server communication is possible.
