Wikipedia articles with GND identifiers. The communication system offers a reduced instruction set to read and write datapoint values. These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.

Retrieved from ” https: RF enables communication in the The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:.

Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.

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. Datapoints may be accessed through unicast or multicast mechanisms. It is OSI 7-layer model compliant:. Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.

There are three categories of KNX devices:. Views Read Edit View history. SELV power is distributed via the same pair for low-power devices. This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels.

PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. 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.

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

Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. 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.

Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system. For the jazz record label, see Konnex Records. In other projects Wikimedia Commons. KNX can link up to 57, devices using bit addresses.

KNX (standard)

From Wikipedia, the free encyclopedia. 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.

The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July A KNX installation always consists of a set of devices connected to the bus or network. The standardised containers for these datapoints are group objects and interface object properties.

KNX (standard) – Wikipedia

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 had partnership agreements with over 77, installer companies in countries and more than registered training centres. An installation has to be configured at the network topology level and at individual nodes or devices. Device models vary according to node roles, capabilities, management features and configuration modes, tupes are all laid down in the profiles.

Ignoring any preamble for medium-specific access and collision control, a frame format is generally:.

satapoint KNX is not 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. Costs Mesh networking Organizations Smart grid. KNX is an approved standard by the following organisations, inter alia: To logically link applications datapoints across the network, KNX has three underlying binding schemes: Elements Actuators Hardware controllers Sensors.

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. Actuators Hardware controllers Sensors. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.

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

KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Computer buses Building automation Home automation.

Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. An alternative variant, PLhas a carrier frequency centred on A KNX wired network can be formed with treeline and star topologies, which can inrerworking mixed as needed; ring topologies are not supported.

On this network, the devices form distributed applications and tight interaction is possible. KNX Powerline is aimed at smart white goods, but the take-up has been low. By using this site, you agree to the Terms of Use and Privacy Policy.
