Understanding Standard/Virtual KNX Group Addresses in the Controller

The controller uses two types of KNX group addresses to manage communication:

Understanding the difference between these types helps determine which to use based on your system configuration.

If you have real KNX devices:

Use standard KNX group addresses for communication with commissioned KNX devices.
Use virtual KNX group addresses for all other purposes.

If you do not have KNX devices:

Use only virtual KNX group addresses.
Do not use standard KNX group addresses, as this may cause bus issues and overload the controller.
