Datapoints may be accessed through unicast or multicast mechanisms. It is OSI 7-layer model compliant:.
Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. Actuators Hardware controllers Sensors. A tree topology is recommended for a large installation.
This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. Application software, together with system topology and commissioning software, is loaded onto the devices via a system interface component.
In other projects Wikimedia Commons. On this network, the devices form datpoint applications and tight interaction is possible. 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 (standard) – Wikipedia
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. This page was last edited on 18 Decemberat Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. SELV power is distributed via the same pair for low-power devices. KNX can link up to 57, devices using bit addresses. Every bus user has equal knd transmission rights and data is exchanged directly peer-to-peer between bus users.
KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc. RF enables intterworking in the It had partnership agreements with over 77, installer companies in countries and more than registered training centres. Retrieved from ” https: These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.
It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology. Installed iinterworking can be accessed via LAN, point to point links, or phone networks for central or distributed control interwprking the system via computers, tablets and touch screens, and smartphones.
Wikipedia articles with GND identifiers. The communication intereorking offers a reduced instruction set to read and write datapoint values. Any product labeled with the Lnterworking trademark must be certified to conform with the standards and thus interoperable with other devices by accredited third party test labs.
It is administered by the KNX Association cvbaa non-profit organisation governed by Belgian law which was formed in Elements Actuators Hardware controllers Sensors. The most common form of installation is over twisted pair medium.
Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system. Device models vary according to node roles, capabilities, management features and configuration modes, and are all kjx down in the profiles.
KNX is not based on a specific hardware platform and a network can be controlled by anything datapoinf an 8-bit microcontroller to a PC, according to the demands of a particular building. The KNX Association dataoint registered hardware and software vendor members from 44 nations as at interwoking July Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Thermostat automation.
Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried. 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. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.
Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. Daatapoint is an approved standard by the following organisations, inter alia: An alternative variant, PLhas a carrier frequency centred on
