6.7.1
Updating the operating system
Introduction
If the operating system version of an HMI device is not compatible with the configuration, you
need to update the operating system of the HMI device. Depending on the protocol used, the
operating system on the HMI device is updated automatically upon prompting when the
project is loaded. Thereafter, the loading continues. Otherwise, the loading of the project is
canceled. In this case, you have to start the update of the operating system manually.
Updating the operating system
To update the operating system of an HMI device, connect the HMI device to the
configuration PC. If possible, use the interface with the highest bandwidth, such as Ethernet,
to make this connection.
"Reset to factory settings"
If the operating system on the HMI device is no longer functional, update your operating
system and restore the factory settings on the HMI device. If the HMI device detects the fault
itself, the HMI device automatically restarts in "bootstrapping" mode and issues a
corresponding message.

Updating the operating system of the HMI device
If possible, use the interface with the highest bandwidth, such as Ethernet, to make the
connection.
NOTICE
Updating the operating system deletes all data on the HMI device
If you update the operating system, data on the target system is deleted. Therefore, first
back up the following data:
• User administration
• Recipes
A reset to the factory settings also deletes the license keys. Back up the license keys as
well before restoring the factory settings.
Note
Calibrating the touch screen
After the update, you may have to recalibrate the touch screen.
