The KNX network driver must have been be added to the Drivers node, the Data Defs must be loaded and connection to the physical KNXnet/IP network configured.
In the Driver Manager view, double click on the KNX Network driver to open its Device Manager view.
Click New to display the New [Devices] dialogue.
Enter the Number [of Devices] to Add and click OK to display the New dialogue.
NOTE: When Devices are added by this method, you will need to configure both the Knx Installation and Ip Address properties of each Device. It is not necessary to configure the Individual Device Address property because this will be discovered from the Device itself when the KNX network driver first tries to connect to the Device, by using the Ip Address.
