In this step the VI frameworks is expected to be populated.
Normally the configuration would provide back the "definition" to enable a GUI
since we don't have a GUI the sOP has a predefined configuration instance.

Is nothing to modify therefore PUT is used for create since the user defines
The label. However there is no update allowed.
