SELV power is distributed via the same pair for low-power devices. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of interwlrking packets and half duplex bi-directional communication. To logically link applications datapoints across the network, KNX has three underlying binding schemes: Datapoints may be accessed through unicast or multicast mechanisms.
An installation has to be configured at the network topology level and at individual nodes or devices. An alternative variant, PLhas a carrier frequency centred on The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. For the datapiint record label, see Konnex Records. Elements Actuators Hardware controllers Sensors. Actuators Hardware controllers Sensors.
A KNX installation always consists of a set of devices connected to the bus or network. Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system.
KNX can link up to 57, devices using bit addresses. The most common form of installation is over twisted pair medium. Any product labeled with the KNX trademark must be certified to datzpoint with the standards and thus interoperable with other devices interwotking accredited third party test labs.
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.
KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. Audio and video Heating, ventilation and air conditioning Datapkint control system Other systems Robotics Security Thermostat automation. KNX is kmx 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.
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. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.
From Wikipedia, the free encyclopedia. KNX Powerline is aimed at smart white goods, but the take-up has been low. The standardised containers for these datapoints are group objects and interface object properties. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July 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.
Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. It also uses CSMA.
In other projects Wikimedia Commons. RF enables communication in the 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.
It had partnership agreements with over 77, installer companies in countries and more than registered training centres. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.
It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.

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. This page was last edited on 18 Decemberinterwoking It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in There are three categories of KNX devices:.
This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. It is OSI 7-layer model compliant:. Views Read Edit View history. KNX is an approved standard by the following organisations, inter alia:
