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".

Note: The System management panel (panels/vision/SysMgm) is not kept in the /panels/ directory of the current project but is saved in the WinCC OA installation path. However, it can still be opened from within the application like any other panel as though it was actually kept there. The reason for this lies in the mechanism of the "hierarchical search" which forms the basis for industry packages. For more information about the hierarchical search and industry paths, see the Projects section.
