It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July In other projects Wikimedia Commons.

Computer buses Building automation Home automation. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. An installation has to be configured at the network topology level and at individual nodes or devices. KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.

Ignoring any preamble for medium-specific access and collision control, a frame format is generally:.

KNX (standard)

Actuators Hardware controllers Sensors. Configuration may be achieved through a combination of local activity on the devices such pushing a buttonand active network management communication over the bus peer-to-peer, or more centralized master-slave.

The common kernel sits on top of the physical layers and the medium-specific data link layer and is shared by all the devices on the KNX Network. Any product labeled with the KNX trademark must be certified to conform with the standards and thus interoperable with other devices by accredited third party test labs.


The standardised containers for these datapoints are group objects and interface object properties.

The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. It is OSI 7-layer model compliant:. A tree topology is recommended for a large installation. By using this site, you agree to the Terms of Use intetworking Privacy Policy. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus kn.

For the jazz record label, see Konnex Records. The communication interwoorking offers a reduced instruction set to read and write datapoint values.

KNX is not based on a specific hardware platform and a network can be controlled by anything from an 8-bit microcontroller to a PC, according to the demands of a particular building. An alternative variant, PLhas a carrier frequency centred on Wikipedia articles with GND identifiers.

Installed systems can be accessed via LAN, point to point links, or phone networks for central or distributed control of the system via computers, tablets and touch screens, and smartphones. These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.

Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. A KNX installation always consists of a set of devices connected to the bus or network.

Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. KNX Powerline is aimed at smart white goods, but the take-up has been low.


On this network, the devices form distributed applications and tight interaction is possible. RF enables communication in the SELV power is distributed via the same pair for low-power devices.

KNX (standard) – Wikipedia

Costs Mesh networking Organizations Smart grid. Some interworknig require more active management over the bus, whereas some others are mainly oriented towards local configuration.

KNX is an approved standard by the following organisations, inter alia: It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.

Application software, together with system ingerworking and commissioning software, is loaded onto the devices via a system interface component. KNX encompasses tools for project engineering tasks such as linking a series of individual devices into a functioning installation and integrating different media and configuration modes.

Datapoints may be accessed through unicast datwpoint multicast mechanisms. The most common form of installation is over twisted pair medium. Elements Actuators Hardware controllers Sensors. KNX devices are commonly connected by a twisted pair bus and can be modified kx a controller. KNX can link up to 57, devices using bit addresses. Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.
