Central to the KNX architecture concepts are datapoints inputs, outputs, parameters, and diagnostic data which represent process and control variables in the system. The standardised containers for these datapoints are group objects and interface object properties.

RF enables communication in the Datapoints may be accessed through unicast or multicast mechanisms. KNX can link up to 57, devices using bit addresses. This is implemented via interworking models with standardised datapoint types and objectsmodelling logical device channels. A KNX installation always consists of a set of devices connected to the bus or network.


KNX is the standard that unites advantages and guarantees to strict regulation. Elements Actuators Hardware controllers Sensors.

Blumotix has been adhering to Konnex Standard for years because only a high standard and shared worldwide Protocol can improve the home automation market to the benefit of manufacturers, technicians and end users. It is OSI 7-layer model compliant:. An installation has to be configured at the network topology level and at individual nodes or devices. peotocol

There are three categories of KNX devices:. Computer buses Building automation Home automation. Device models vary according to node roles, capabilities, management features and configuration modes, and are all laid down in the profiles.

KNX (standard)

From Wikipedia, the free encyclopedia. KNX devices are commonly jonnex by a twisted pair bus and can be modified from a controller. 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. An alternative variant, PLhas a carrier frequency centred on 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.

Costs Mesh networking Organizations Smart grid. A KNX wired network kkonnex be formed with treeline and star topologies, which can be mixed as needed; ring topologies are not supported.

In particular, the control experience is in the act of attention and maintenance. Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. Actuators Hardware controllers Sensors.

The most common form of installation is over twisted pair medium. Datapoints have to confirm to standardised datapoint typesthemselves komnex into functional blocks.

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:.
