Datapoints have to confirm to standardised datapoint typesthemselves grouped into functional blocks. 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.
Ignoring any preamble for medium-specific access and collision control, a frame format is generally:. This page was last edited on 18 Decemberat Every bus user has equal data transmission typpes and data is exchanged directly peer-to-peer between bus users.
KNX can link up to 57, devices using bit addresses.
Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Thermostat automation. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. Datapont logically link applications datapoints across the network, KNX has three underlying binding schemes: KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc.
A tree topology is recommended for a large installation. A KNX installation always consists of a set of devices connected to the bus or network. 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. Retrieved from ” https: Elements Actuators Hardware controllers Sensors.
Actuators Hardware controllers Sensors. On this network, the devices form distributed applications and tight interaction is possible. It also uses CSMA. It had partnership agreements with over 77, installer companies in countries and more than registered training intrrworking. These functional blocks and datapoint types are intrworking to applications fields, but some of them are of general use such as date and time. Computer buses Building automation Home automation.
The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:.
This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. Application software, together with system topology datapojnt commissioning software, is loaded onto the devices via a system interface component. Installed systems can be accessed via LAN, point to point links, or phone networks for central or interworjing control of the system via computers, tablets and touch screens, data;oint smartphones.
Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. Any product labeled with the KNX trademark must be certified to conform with the standards and thus interoperable with other devices interworkiny accredited third party test labs. An alternative variant, Datwpointhas a carrier frequency centred on Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried.
KNX (standard) – Wikipedia
Datapoints may be accessed through unicast or multicast mechanisms. 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.
From Wikipedia, the free encyclopedia. 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 standardised containers for these datapoints are group objects and interface object properties. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication.
The tyes system typea a reduced instruction set to read and write datapoint values. For the jazz record label, see Konnex Records. KNX is an approved standard by the following organisations, inter alia: It is OSI 7-layer model compliant:. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed. Views Read Edit View history.
The most common form of installation is over twisted pair medium. SELV power is distributed via the same pair for low-power devices. It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.
