You cannot enter any forwarding destinations for this type of forwarding from the station device. You must use AMO ZIEL or Configuration Management. You can only activate or deactivate it by code from the station device or by using AMO ACTDA or Configuration Management.

A special feature is that you cannot activate the type of forwarding (CFU or CFB, for example) for each separately, but must do all at once. If you later add a destination for a type of forwarding, it is automatically activated if this type of forwarding was activated for the previously entered destination.

Example:

You have entered and activated a CFNR destination for CFVAR=SYSTEM. If you later enter a CFB destination, it is automatically activated.
