KNX (standard) – Wikipedia

A KNX installation always consists of a set of dataooint connected to the bus or network. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller.

Datapoints may be accessed through unicast or multicast mechanisms. Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. A KNX wired network can datapointt formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.

Views Read Edit View history. For the jazz record label, see Konnex Records. A tree topology is recommended for a large installation. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried.

Actuators Hardware controllers Sensors. The bus is routed in parallel to typfs electrical power supply to all devices and systems on the network linking:. Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.

KNX (standard)

These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time. It had partnership agreements with over 77, installer companies in countries and more than registered training centres.


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.

Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Interworkiing automation. KNX is an approved standard by the following organisations, inter alia: The most common form of installation is over twisted pair medium.

An installation has to be configured at the network topology level and at individual nodes or devices. Datapoknt alternative variant, PLhas a carrier frequency centred on This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels.

Knd from ” https: Computer buses Building automation Home automation. KNX can link up to 57, devices using bit addresses. On this network, the devices form distributed applications and tight interaction is possible. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July Elements Actuators Hardware controllers Sensors. To logically link applications datapoints across the network, KNX has three underlying binding schemes: Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.

KNX Powerline is aimed at smart white goods, but the take-up has been low. In other projects Wikimedia Commons. 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.

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 devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. Ignoring dataponit preamble for medium-specific access and collision control, a frame format is generally:. It is OSI 7-layer model compliant:. SELV power is distributed via the same pair for low-power devices. There are three categories of KNX devices:.

The common kernel sits on top of the physical layers and tpes medium-specific data link layer and is shared by all the devices on the KNX Network. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed.

It can use twisted pairpowerlineRFinfrared interworkjng Ethernet links in a treeline or star topology. This page was last edited on 18 Decemberat Typpes Mesh networking Organizations Smart grid. 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. 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.

Wikipedia articles with GND identifiers. PL power-line transmission interworing delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. It also uses CSMA. Devices may be identified and subsequently accessed throughout the network either by their individual address, or by their unique serial number, depending on the configuration mode.
