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.

On this network, the devices form distributed applications and tight interaction is possible. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. RF enables communication in the SELV power is distributed via the same pair for low-power devices.

dayapoint This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. An installation has to be configured at the network inetrworking level and at individual nodes or devices. Datapoints have to confirm to standardised datapoint typestyeps grouped into functional blocks.

Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Thermostat automation. For the jazz record label, see Konnex Records. Wikipedia articles with GND identifiers. An alternative variant, PLhas a carrier frequency centred on A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.

It had partnership agreements with over 77, installer companies in countries and more than registered training centres. The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:.


A KNX installation always consists of a set of devices connected to the bus or network. Views Read Edit View history. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July Actuators Hardware controllers Sensors. Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. From Wikipedia, the free encyclopedia. It is OSI onterworking model compliant:.

KNX (standard) – Wikipedia

Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component. The common kernel sits on top of the physical layers and the medium-specific data link layer and is shared by all the devices on the KNX Network. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.

It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology. The most common form of installation is over twisted pair medium. 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 also uses CSMA. KNX is an approved standard by the following organisations, inter alia: KNX can link up to 57, devices using bit addresses.

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

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.

These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried.

The communication system offers a reduced instruction set to read and write kns values. Computer buses Building automation Home automation. To logically link applications datapoints across the network, KNX has three underlying binding schemes: Elements Actuators Hardware controllers Sensors.

It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Costs Mesh networking Organizations Smart grid. Retrieved from interworkiny https: KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.

PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. There are three categories of KNX devices:. 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.
