Datapoints may be accessed through unicast or multicast mechanisms. Devices may be identified and subsequently accessed throughout the network either by their individual address, or by their unique serial number, depending prottocol the configuration mode. In particular, the control experience is in the act of attention and maintenance. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.
The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. An installation has to be configured at the network topology level and at individual nodes or devices. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. 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.
PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.

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 is an approved standard by the following organisations, inter alia: Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent protocpl and control variables in the system.
Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. From Wikipedia, the free encyclopedia.

An alternative variant, PLhas a carrier frequency centred on The most common form of installation is over twisted pair medium.
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. Views Read Edit View history.
KNX can link up to 57, devices using bit addresses. The standardised containers for these datapoints are group objects and interface object properties. KNX is the standard that unites advantages and guarantees to strict regulation. A KNX installation always consists of a set of devices connected to the bus or network. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users. 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.
This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. Elements Actuators Hardware controllers Sensors. The communication system offers a reduced instruction set to read and write datapoint values.
SELV power is distributed via the same pair for low-power devices. A tree topology is recommended for a large installation. For the jazz record label, see Konnex Records. One of the maximum values of all manufacturers in KNX mode is the interoperability that is the possibility to set up systems on which devices from different manufacturers can be installed.
The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July It is OSI 7-layer model compliant:.

It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.
On this network, the devices form distributed applications and tight interaction is possible. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. Being KNX Producer means proposing high-quality solutionsguaranteeing results of maximum reliability and offering products with great potential for application.
