KNX INTERWORKING DATAPOINT TYPES PDF

It describes the data, setting the rules about the format and values to be allowed, and it holds the bytes containing the data. A datapoint type is identified by its main number and a sub number. Each main number corresponds to a datapoint type with a particular structure. The sub numbers correspond to different interpretations or naming of this structure. The Qt KNX module provides a class for each datapoint type with the main number less than 30 and sub number less than All datapoint types with the same main number inherit from a datapoint type class representing the main number datapoint type characteristics.

The KNX Association had registered hardware and software vendor members from 44 nations as at 1 July 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.

Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles. Every bus user has equal data transmission rights and data is exchanged directly peer-to-peer between bus users. KNX standard — Wikipedia This page was last edited on 18 Decemberat KNX devices are commonly connected by a twisted pair bus and can be modified from a controller.

The standardised containers for these datapoints are group objects and interface object properties. In other projects Wikimedia Commons. Configuration may be achieved through a combination of local activity on the devices such pushing a buttonand interdorking network management communication over the bus peer-to-peer, or more centralized master-slave.

This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. 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. SELV power is distributed via the same pair for low-power devices.

An interworikng variant, PLhas a carrier frequency centred on KNX Powerline is aimed at smart white goods, but the take-up has been low. It can use twisted pairpowerlineRFinfrared or Ethernet links in a treeline or star topology.

The bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:. 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.

Views Read Edit View history. To logically link applications datapoints across the network, KNX has three underlying binding schemes: The communication system offers a reduced instruction set to read and write datapoint values. These functional blocks and datapoint types typpes related to applications fields, but some of them are of general use such as date and time.

Audio and video Heating, ventilation and air conditioning Lighting control system Other systems Robotics Security Thermostat automation. The most common form of installation is over twisted pair medium. KNX standard From Wikipedia, the free encyclopedia. PL power-line transmission is delivered using spread frequency shift keying signalling with asynchronous transmission of data packets and half duplex bi-directional communication. KNX can link up to 57, devices using bit addresses.
