Open data communication in building automation, controls and building management — Home and building electronic systems — KNXnet/IP communication
This document 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 twisted pair transmission speed) backbone in KNX installations.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document is intended for the design of new buildings and the retrofit of existing buildings in terms
of acceptable indoor environment, practical energy conservation and efficiency.
KNXnet/IP is a protocol designed to transport KNX home and building electronic system (HBES) control
frames over an IP network. It is used as an infrastructure backbone for connecting KNX sub-networks,
as a communication medium for KNX-IP devices and to provide IP based services for clients (e.g.
connecting a tool software to a KNX installation). The main advantages of using IP for these purposes
are that IP network in
