A KNX installation always consists of a set of devices connected to the bus or network. There are three categories of KNX devices:.
KNX (standard) – Wikipedia
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. An alternative variant, PLhas a carrier frequency ,nx on On this network, the devices form distributed applications and tight interaction is possible. Views Read Edit View history. 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.
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. For the jazz record label, see Konnex Records.
Configuration may be achieved through a combination of local activity on the devices such pushing tyes buttonand active network management communication over the bus peer-to-peer, or more centralized master-slave. It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.
Computer buses Building automation Home automation. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried.
KNX devices are commonly connected by a twisted pair bus and can be modified from a intrrworking. 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. A tree topology is recommended for a large installation. The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:.
The communication system offers a reduced instruction set to read and write datapoint values. RF enables communication in the Central to the KNX architecture concepts are datapoints inputs, outputs, onx, and diagnostic data which represent process and control variables in interworkig system.
PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. Actuators Hardware controllers Sensors. To logically link applications datapoints across the network, KNX knc three underlying binding schemes: The KNX Association had registered hardware and software vendor interaorking from 44 nations as at 1 July Ignoring any preamble for medium-specific access and collision control, a frame format is generally:.
Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. An installation has to be configured at the network topology level and at individual nodes or interaorking. 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.
SELV power is distributed via the same pair for low-power devices. 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.
KNX Powerline is aimed at smart white goods, but the take-up has been low. Costs Mesh networking Organizations Smart grid.
The standardised containers for these datapoints are group objects and interface object properties. The most common form of installation is over twisted pair medium.
