KNXnet/IP device address

What KNXnet/IP device address information does the KNX driver need and how does it obtain it?

The two primary KNXnet/IP device types are Interfaces and Routers. There are three addresses the KNXnet/IP driver needs to communicate with either of these device types:

  • Ip Address: Obtained from the KNXnet/IP device either over the KNX network using the KNXnet/IP driver’s Search Network For Devices feature or by Manual data entry.
  • Control Port Number: Obtained from the KNXnet/IP device either over the KNX network using the KNXnet/IP driver’s Search Network For Devices feature or by Manual data entry or by default.

    NOTE: The default Control Port Number is 3671.

  • Individual Device Address: Obtained from the KNXnet/IP device either over the KNX network using the KNXnet/IP driver’s Search Network For Devices feature or by Manual data entry or by using the KNXnet/IP driver’s Import Devices from knxproj file

    NOTE: Manual data entry is not available in v29 of the KNXnet/IP driver.

The KNXnet/IP driver’s Search Network For Devices (Device Discovery) feature uses a Multicast connection.

NOTE: If both the Ip Address and Control Port Number are known by the KNXnet/IP driver, then it will not initiate a Search Request via a Multicast connection.
