KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.

KNX (standard) – Wikipedia

The standardised containers for these datapoints are group objects and interface object properties. It also uses CSMA. For the jazz record label, see Konnex Records. On this network, the devices form distributed applications and tight interaction is possible. In other projects Wikimedia Commons. From Wikipedia, the free encyclopedia. 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.

To logically link applications datapoints across the network, KNX has three underlying binding schemes: RF enables communication in the 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. An alternative variant, PLhas a carrier frequency centred on It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in 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.


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.

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. Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.

This page was last edited on 18 Decemberat Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.

The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.

Datapoints may be accessed through unicast or multicast mechanisms. It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.

The KNX Association had registered hardware and software datwpoint members from 44 nations as at 1 July Elements Actuators Hardware controllers Sensors.

It had partnership agreements with over 77, installer companies in countries and more than registered training centres. KNX Powerline is aimed at smart white goods, but the take-up has been low. This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels.

KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. It is OSI 7-layer model compliant:. The most common form of installation is over twisted pair medium. Devices may be identified and subsequently accessed throughout the network either by their individual address, intreworking by their unique serial number, depending on the configuration mode.


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. An installation has to be configured at the network topology level and at individual nodes or devices. Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.

KNX can link up ttypes 57, devices using bit addresses. Wikipedia articles with GND identifiers.

The communication system offers a reduced instruction set to read and write datapoint values. There are three categories of KNX devices:. Computer buses Building automation Home automation. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.

Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. KNX is an approved standard by the following organisations, inter alia: Views Read Edit View history. These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.
