Hello Jim, thank you for your answer. It is no big problem. The reason is I want to use different front panels with different controls (placing as a subpanel), but the main program in the background is always the same. Due to your answer I have to lock the registration to the controls names now and I'm not very flexible. It would be more comfortable to use only "mechanical action" instead of names. Therefore I'm very interrested in your workaround.
Regards Heinrich
