Archiving of images and diagnostic information on a PC
You can find the program described in this section on the Web pages of Siemens Online
Product Support (https://support.industry.siemens.com/cs/ww/en/ps/15147/ae
).
Using the "MMIDiagnosticsGUI.exe" file, you archive diagnostic data records in the form of
CSV files and diagnostics images as bitmaps on a PC. A text file containing bitmap details is
sent along with the diagnostics images.
