7.7 Updating the operating system
7.7.1 Overview
Updating the operating system
A compatibility conflict may occur when transferring a project to the HMI device. This is
caused by different versions of the configuration software used and the HMI device image
available on the HMI device. If there are different versions, the transfer is aborted. A
message indicating a compatibility conflict is displayed on the configuration PC.
There are two ways to match the versions:
● Update the HMI device image if the project was created with the most recent version of
the configuration software.
● Transfer a matching version of the HMI device image if you do not want to adapt the
project for the HMI device to the most recent version of the configuration software
for the project.
NOTICE
Data loss
All data on the HMI device, such as the project and licenses, will be deleted when you
update the operating system.
Note
When WinAC MP is used, all data channel parameters are reset.
Note
Calibrating the touch screen
After the update, you may have to recalibrate the touch screen.
