5.15.2  Restoring from external storage medium – Restore 
Use this function to restore data from a storage medium to the HMI device. 
A restore operation deletes the old data from flash memory of the HMI device on 
confirmation. The data backed up on the storage medium is then transferred. 
Requirement  
●  The Control Panel is open. 
●  The storage medium with the backed up data is inserted in the HMI device. 
Procedure 
1.  Open the "Service & Commissioning" dialog with the Service & Commissioning icon. 
2.  Change to the "Restore" tab. 
 
 
 
All data on the HMI device is deleted during a restore operation. License keys are only 
deleted after a security prompt. 
Back up data before restore operations, if required. 
3.  Press the "Next" button. 
The Restore from external memory dialog is displayed. The dialog corresponds to the 
"Backup to external memory" dialog in the section  
"Saving to external storage medium – backup (Page 144)". 
The "0 devices found" message appears if there is no storage medium in the HMI device 
or if it is defective. Insert a storage media or replace the storage medium. 
4.  Press the "Refresh" button. 
The "Type of HMI interface" group is updated. The HMI device checks the storage 
medium. Information about this storage medium is displayed in the "status information" 
field. 
5.  Select the storage medium with the required backup in the "Type of HMI interface" group.
