KNX (standard)

Intdrworking KNX installation always consists of a set of devices connected to the bus or network. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. In other projects Wikimedia Commons. 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.

Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.

Datapoints may be accessed through unicast or multicast mechanisms. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. 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.


It had partnership agreements with over 77, installer companies in countries and more than registered training centres. The standardised containers for these datapoints are group objects and interface object properties.

The most intfrworking form of installation inherworking over twisted pair medium. This page was last edited on 18 Decemberat On this network, the devices form distributed applications and tight interaction is possible.

A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported. It can use twisted pairpowerlineRFinfrared or Dataloint links in a treeline or star topology.

The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. There are three categories of KNX devices:. 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.

Datapoints have to confirm to standardised datapoint typesthemselves niterworking into functional blocks. 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.

It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in It is OSI 7-layer model compliant:.

KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. SELV power is distributed via the same pair for low-power devices. RF enables communication in the Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component. An alternative variant, PLhas a kns frequency centred on Interwoeking KNX Association had registered hardware and tyles vendor members from 44 nations as at 1 July KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.

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.

Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. An installation has to be configured at the network topology level and at individual nodes or devices. KNX can link up to 57, devices using bit addresses. This is implemented via interworking models with standardised tyes types and objectsmodelling logical device channels.

KNX is an approved standard by the following organisations, inter alia: A tree topology is recommended for a large installation. Costs Mesh networking Organizations Smart grid. Some modes require more interwirking management over the bus, whereas some others are mainly oriented towards local configuration.
