It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system. 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. Datapoints may be accessed through unicast or multicast mechanisms. Protocll devices are commonly connected by a twisted pair bus konenx 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.

KNX can link up to 57, devices using bit addresses. KNX encompasses tools for project engineering tasks such as linking a series of individual devices into a functioning installation and integrating different media and configuration modes.

These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time. There are three categories of KNX devices:. An installation has to be configured at the network topology level and at individual nodes or devices.

The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July KNX Powerline is aimed at smart white goods, but the take-up has been low. 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.

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

To logically link applications datapoints across the network, KNX has three underlying binding schemes: It is the only worldwide recognize technology, the standard that combines advantages and guarantees with a strict regulation. In particular, the control experience is in the act of attention and maintenance.

This page was last edited on 18 Decemberat KNX is the standard that unites advantages and guarantees to strict regulation. It had partnership agreements with over 77, installer companies in countries peotocol more than registered training centres.

Being KNX Producer means proposing high-quality solutionsguaranteeing results of maximum reliability and offering products with great potential for application.

A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.

Four communication infrastructures are supported: From Wikipedia, the free encyclopedia. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.

The common kernel sits on top of the physical layers and the medium-specific data link pprotocol and is shared konmex all the devices on the KNX Network. It also uses CSMA. 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.

Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. Actuators Hardware controllers Sensors. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.

KNX is an approved standard by the following organisations, inter alia: A tree topology is recommended for a large installation.

Retrieved from ” https: KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.

KNX (standard)

Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. 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.

The most common orotocol of installation is over twisted pair medium.

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. The communication system offers a reduced instruction set to read and write datapoint values.
