Retrieved from ” https: Views Read Edit View history. KNX is konne approved standard by the following organisations, inter alia: KNX is the standard that unites advantages and guarantees to strict regulation.

The communication system offers a reduced instruction ptotocol to read and write datapoint values. To logically link applications datapoints across the network, KNX has three underlying binding schemes: KNX can link up to 57, devices using bit addresses. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.

An installation has to be configured at the network topology level and at individual nodes or devices. A tree topology is recommended for a large installation. In potocol projects Wikimedia Commons. Wikipedia articles with GND identifiers.

KNX (standard)

KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. It is OSI 7-layer model compliant:. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July SELV power is distributed via the same pair for low-power devices.


Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.

Computer buses Building automation Home automation. From Wikipedia, the free encyclopedia. An alternative variant, PLhas a carrier frequency centred on RF enables communication in the Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. Datapoints may be accessed through unicast or multicast mechanisms.

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. Utilizziamo i cookie per essere sicuri che tu possa avere la migliore esperienza sul nostro sito.

A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported. KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.

If you continue to use this site we assume that you will be happy. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users. The bus is routed in protocok 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. For the jazz record label, see Konnex Records. By using this site, you agree to the Terms of Use and Privacy Policy.

Blumotix has been adhering to Konnex Standard for years because only a high standard and shared worldwide Protocol can improve the home automation market to the benefit of manufacturers, technicians and end users. Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. On this network, the devices form distributed applications and tight interaction is possible.


Four communication infrastructures are supported: Being KNX Producer means proposing high-quality solutionsguaranteeing results of maximum reliability and offering products with great potential for application. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.

Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. The most common form of installation is over twisted pair medium.

It is the only worldwide recognize technology, the standard that combines advantages and guarantees with a strict regulation. 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. It had partnership agreements with over 77, installer companies in countries and more than registered training centres.

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. It also uses CSMA. 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.
