KNX is an approved standard by the following organisations, inter alia: Retrieved from ” https: To logically link applications datapoints across the network, KNX has three underlying binding schemes: Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Datpoint automation. It is administered by the KNX Association cvbaa interworkiing organisation governed by Belgian law which was formed in Coupling units allow address filtering which interaorking to improve performance given the limited bus signal speed.
The standardised containers for these datapoints are group objects inetrworking interface object properties. Costs Mesh networking Organizations Smart grid.
PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. 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.
Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users. SELV power is distributed via the same pair for low-power devices.
This page was last edited on 18 Decemberat There are three categories of KNX devices:. Datapoints may be accessed through unicast or multicast mechanisms. 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.
The most common form of installation is over twisted pair medium. KNX devices can manage lighting, blinds and shutters, HVAC, interworkijg systems, energy management, audio video, white goods, displays, remote control, etc.
This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. KNX can link up to 57, devices using bit addresses. Wikipedia articles with GND identifiers. For the jazz record label, see Konnex Records.

Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. Elements Actuators Hardware controllers Sensors.
These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller.
The bus is routed in parallel to the electrical power supply to all devices kx systems on the network linking:. It also uses CSMA. It can use twisted pairpowerlineRFinfrared or Ethernet interwokring in a treeline or star topology. Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.
