Panels and Presentation

Due to enhancements to the WinCC OA Layout Management feature the existing behavior and default values have changed. This must be considered when upgrading your WinCC OA project. It may be necessary to adjust your existing layout settings to get the previous visuals representation of your panels.

Note that following warning message at project start indicates that a picture used inside of the project is not conform to the rules of the latest "libpng" library.

 "WCCOAui (1), <DATE and TIME>, SYS, WARNING, 54, Unexpected state, Qt, libpng warning: iCCP: profile 'ICC Profile': 'CMYK': invalid ICC profile color space"

To remove this warning please update/remove the outdated ICC Profile of your picture. One option for this purpose may be the pngcrush tool.#

Note that an old project, which uses the panel topology feature, has to contain the panel files when updating the project. For the generation of the Panel Topology sum alert data points, project panels are required. Without these, the panel topology sum alert data points cannot be created correctly. Therefore, the project panels have to exist when updating the project. Otherwise the sum alert data points will be deleted or generated wrong.
