Introduction
A restore operation deletes the old data from flash memory of the HMI device on
confirmation. The data stored on the external memory is then copied to the internal flash
Flash memory.
Requirements
● The external memory holding the backed up data is inserted in the HMI device.
● You have opened the "Backup/Restore" dialog with the "Backup/Restore"
icon.
NOTICE
Loss of data possible
All data on the HMI device will be deleted during a restore operation. License keys are
deleted after counter-inquiry.
Back up the HMI device's data before restoring if required.
External memory with data backup
If several external memories with data backups are plugged in, the data cannot
be restored.
Remove the external memory with the data backups not needed.
