These devices are managed within a project. This makes configuration easier and secures a correct assignment of the appropriate devices. This way, all receive the same project ID. **Important**\\ In order to enable all devices to exchange global potentiometers via UDP, their project IDs have to be identical. In a project, up to 20 global potentiometers can be used. All global potentiometers can be used in every device of the project, for example to change levels in output functions. (See [[tb9:output_functions|Output Functions]]) [{{ tb9_globalpoti.png?1000&nolink |//Global Control - Potentiometers//}}] Select the ''Global Control'' node in the project tree. On the ''Potentiometer'' tab, you can assign distinctive names to the global potentiometers. A global potentiometer is controlled by an assigned physical potentiometer. For this, select a ''Device'' and an actual ''Potentiometer'' on this tab under ''Potentiometer Source''.
