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.
