KNX (Konnex) is the international standard ISO/IEC 14543-3 in the field of building automation. The KNX bus system is the successor or further development of EIB, BatiBus and EHS. A KNX system is used in these areas, among others:
- Heating technology
- Alarm systems
- Consumer electronics
- Building systems technology
With the help of KNX, the devices in these areas are both monitored and controlled. As all sensors and actuators are networked via the KNX fieldbus, the system is expandable and can be adapted at any time. The individual data and commands are configured via software, so that they can be changed again and again if required. Therefore, the following is required for a functioning KNX system:
- Bus line (separate control network with 29 V DC voltage, which must be laid parallel to the power line - acts as a communication link)
- Sensors (e.g. a motion detector)
- Actuators (e.g. lighting)
The sequence of a KNX system could therefore look as follows: The temperature sensor informs the actuator that it is too cold in a room and that the temperature should be increased. The actuator transmits this command via bus line to the heating, which then raises the temperature.
