Wikipedia articles with GND identifiers. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.

A tree topology is recommended for a large installation. On this network, the devices form distributed applications and tight interaction is possible. The bus is routed in parallel to the intdrworking power supply to all devices and systems on the network linking:.

This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. The common kernel sits on top of the intwrworking layers and the medium-specific data link layer and is shared by all the devices on the KNX Network.

Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. KNX Powerline is aimed at smart white goods, but the take-up has been low. There are three categories of KNX devices:.

KNX (standard)

It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology. The communication system offers a reduced instruction set to read and write datapoint values.

Computer buses Building automation Home automation. For the jazz record label, see Konnex Records. 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 also uses CSMA. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. 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 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. Views Read Edit View history. KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.

Costs Mesh networking Organizations Smart grid. Elements Actuators Hardware controllers Sensors. This page was last edited on 18 Decemberat KNX is not based on a specific hardware platform and a network can be controlled by anything from an 8-bit microcontroller to a Khx, according to the demands of a particular building.

Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. It had partnership agreements with over 77, installer companies in countries and more than registered training centres. 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.

A KNX wired network can be formed with treeline and interwworking topologies, which can be mixed as needed; ring topologies are not supported. KNX kns link up to 57, devices using bit addresses. It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Ignoring any preamble for medium-specific access and collision control, a frame format is generally:.


An alternative variant, PLhas a carrier frequency centred on It is OSI 7-layer model compliant:. Dahapoint models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. A KNX installation always consists of a set of devices connected to the bus or network.

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. Knd installation has to be configured at the network topology level and at individual nodes or devices.

The standardised containers for these datapoints are group objects and interface object properties. Retrieved from ” https: Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks.

RF enables communication in the In other projects Wikimedia Commons. These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.

Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Thermostat automation. SELV power is distributed via the same pair for low-power devices.

To logically link applications datapoints across the network, KNX has kxn underlying binding schemes: The most common form of installation is over twisted pair medium.
