Timeout error message due to slow communication with .upd file storage device
If you see the following error message box, then more than 5 seconds has elapsed and the
SIMATIC Automation Tool has not completed processing all the .upd files in the firmware
storage folder. The time required to open and scan all the .upd files is related to data access
time and the number of .upd files in the folder.
● This timeout error can occur when communication with a remote storage device is too
slow.
● To prevent this problem, assign a faster firmware data storage path with the
Tools>Options menu command. Copy the .upd files you need to a faster local storage
device and try the operation again.
