42.1 Introduction and Overview
The KNX standard describes an extensive open system concept for distributed home and building automation
and control. KNX covers the full scope of related applications, including lighting, shading, shutters
and blinds, heating, cooling, ventilation, and air conditioning (HVAC), and remote meter reading.
All relevant communication media are supported. The KNX specification results from a formal merger
of three technologies dedicated to this area: European Installation Bus (EIB), Batibus, and European
Home System (EHS).
Significant parts of the KNX specification are published as European standards, mainly the EN 50090
family but also EN 13321-1:2006 and EN 13321-2:2006. KNX technology is also covered by ISO/IEC 14543-
3-x (2006/2007), which has been published as GB/Z 20965-2007 by the Standardization Administration
of China as well.
The KNX Association is a for-profit organization governed by Belgian law. Its members are mostly
manufacturers and developers of home and building electronic devices, building services equipment,
and related software. They can freely make use of patents held by fellow KNX members in certified KNX
products if this is necessary to make them KNX compatible. The main task of the KNX Association is
to maintain the system master specification frequently referred to as the “KNX Handbook.” Moreover,
the association is responsible for the development and maintenance of a manufacturer-independent
PC-based commissioning tool, trademark licensing (bound to conformance tests), and the certification
of training centers and testing laboratories. Also, the association maintains partnership programs for
national associations, user clubs, and scientific partners.
KNX is more than just a simple network protocol specification. Besides merely defining how data
is transferred, the standard includes rules and definitions of how a KNX system is managed and how
devices implemented by different vendors have to behave to achieve interworking.
