Directory structure
The system directory structure is organized in such a way that user changes are retained if
the software is upgraded.
● User changes to the original software are made in parallel directories.
● There is a clear separation between standard HMI software and customer-specific
enhancements.
● The "mmc2" and "hmi_adv" directories (and their subdirectories) should be read-only
directories. They contain the original software supplied. These directories are overwritten
only if the software is upgraded.
The diagram below shows the priority sequence. This means that: Entries in the directory to
the right overwrite corresponding entries in directories to the left.
