System management
In addition, there is a large number of parameter settings that are saved in internal data points. Internal data points are identified by an understroke "_" in front of the data point type name.
The majority of global parameter settings for a WinCC OA system saved in data points can be managed in dedicated panels. These can be accessed from a central location, the System management panel (<wincc_oa_path>/panels/vision/SysMgm), see also System management.

The System management panel can be opened either from the operating block (the icon with the folder Tool) or from the Start cascade option "System management".
