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. This page was last edited on 24 August , at The communication system offers a reduced instruction set to read and write datapoint values. A KNX installation always consists of a set of devices connected to the bus or network. Many actuators include controller functionality, but also sensor functionality for instance measuring operating hours, number of switch cycles, current, electrical power consumption, and more. An installation has to be configured at the network topology level and at individual nodes or devices. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed.

This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device konneex. In other projects Wikimedia Commons. There are three categories of KNX devices:. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. Application software, together with system topology and commissioning software, is loaded onto the devices via konnnex system interface component.

An installation has to be configured at the network topology level and at individual nodes or devices. Datapoints may konndx accessed through unicast or multicast mechanisms. Many actuators include controller functionality, but also sensor functionality for instance measuring operating hours, number of switch cycles, current, electrical power consumption, and more.
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.

KNX devices can manage lighting, blinds and shutters, HVACsecurity systems, energy management, audio video, white goods, displays, remote control, etc.
Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users.
The standardised containers for these datapoints are group objects and interface object properties. 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 wts the demands of a particular building. These functional blocks and datapoint types are related to applications fields, but some of them are of general use such as date and time.
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. To logically link applications datapoints across the network, KNX has three underlying binding schemes: The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:.
Views Read Edit View history. On this network, the devices form distributed applications and tight interaction is possible.
Configuration may konnwx 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. Ignoring any preamble for medium-specific access and collision control, a frame format is generally:.
KNX Powerline is aimed at smart white goods, but the take-up has been low. An alternative variant, PLhas a carrier frequency centred on Actuators Hardware controllers Sensors. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration.
The most common form of installation is over twisted pair medium. Coupling units allow address filtering which helps to improve performance given the limited bus signal speed.

SELV power wts distributed via the same pair for low-power devices. Devices can also disclose both a manufacturer specific reference and functional manufacturer independent information when queried.
PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. Elements Actuators Hardware controllers Sensors. The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July
