If you enable the "Firmware upgrade" or "Firmware downgrade" option, the operating
system of the HMI device will be updated. All data on the HMI device, including the
HMI device password, is deleted in the process. Settings in the Start Center are
retained. License keys are backed up to the external storage medium before the
operating system update.
Back up your data before the load operation, if necessary.
The project can be loaded into the HMI device if no "Error..."-type alarms occur or if all

automatically backed up to the system memory card during operation in form of a backup
including firmware. Backup is synchronized. You can insert the system memory card into any
HMI device of the same type. After data is copied and a restart has been performed, the HMI
device of the same type is operational.

Only the SIMATIC
HMI Memory Card ≥ 2 GB may be used as a system memory card. All
other memory cards are not recognized as system memory card by the HMI device.
System memory card in a device of a different type
If you use the system memory card of an HMI device in an HMI device of a different type, an
error message is displayed.
For service purposes, use a system memory card only in HMI devices of the same type.
Do not remove the system memory card for "automatic backup" during operation
If the "Automatic
backup" function is activated, the system memory card may only be
