Requirement for online testing
● The project has been transferred to the HMI device.
● The HMI device is in "Online" mode.

In "Online" mode, you can test individual project functions on the HMI device without them
being affected by the controller. Controller tags are updated in this case.
You have the option to test all communication-related functions, such as alarms, etc.

Backup and restore
6.6.1
Overview
Backup and restore
A data backup saves the contents of the internal memory. Alarm logs and process value logs
are always stored on the external storage medium. Alarm logs and process value logs are
not backed up. Manually back up the contents of the memory card if required. If the HMI
device is integrated in a network, you can also back up the data on a network drive.
The following data is backed up:
● Project and HMI device image
● User administration
● Recipe data
● License keys
Use WinCC for backup and restore.
General information
Note
Power failure
If a complete restore operation is interrupted due to power failure on the HMI device, the
operating system of the HMI device may be deleted. In this case, you have to reset the HMI
device to its factory settings. The HMI device automatically switches to "bootstrapping"
mode.
Compatibility conflict
If an alarm is output on the HMI device warning of a compatibility conflict during the restore
operation, the operating system must be updated.
