Actuators Hardware controllers Sensors. In particular, the control experience is in the act of attention and maintenance. This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. Costs Mesh networking Organizations Smart grid. KNX is an approved standard by the following organisations, inter alia: Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.
An installation konmex to be configured at the network topology level and at individual nodes or devices. 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.
Retrieved from ” https: Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.
RF enables communication in the Application software, together with system topology and commissioning software, konnsx loaded onto the devices via a system interface component.
Four communication infrastructures are supported: Datapoints may be accessed through unicast or multicast mechanisms. Utilizziamo i cookie per essere sicuri che tu possa avere la migliore esperienza sul nostro sito.
Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology. It is the only worldwide recognize technology, the standard that combines advantages and guarantees with a strict regulation. For the jazz record label, see Konnex Records.
It had partnership agreements with over 77, installer companies in countries and more than registered training centres. 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.
Views Read Edit View history. The most common form of installation is over twisted pair medium.
It also uses CSMA. Elements Kinnex Hardware controllers Sensors. A tree topology is recommended for a large installation. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.
This page was last edited on 18 Decemberat There are three categories of KNX devices:. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. SELV power is distributed via the same pair for low-power devices.
A KNX wired network can be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.
In other projects Wikimedia Commons. To logically link applications datapoints across the network, KNX has three underlying binding schemes: The communication system offers a reduced instruction set to read and write datapoint values.
KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. Computer buses Building automation Home automation.
It is OSI 7-layer model compliant:. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.
A KNX prptocol always consists of a set of devices connected to the bus or network. Datapoints have to confirm to konnnex datapoint typesthemselves grouped into functional blocks.
The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. An alternative variant, PLhas a carrier frequency centred on 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.
On this network, the devices form distributed applications and tight interaction is possible.
KNX (standard) – Wikipedia
The KNX Association had registered hardware and software protoccol members from 44 nations as at 1 July If you continue to use this site we assume that you will be happy. KNX is not based on a specific hardware platform and a network can be controlled by anything from an 8-bit microcontroller to a Prtoocol, according to the demands of a particular building. KNX is the standard that unites advantages and guarantees to strict regulation.
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. KNX Powerline is aimed at smart white goods, but the take-up protoco been low.
