Sadly, I've never worked with the iX-T7F2, but I have seen a similar issue on the iX-T7A.
This issue would occur due to some bug in a screen or background script. The screen would freeze for some time (while a crash report window is actually hidden behind the screen indicating a non-handled exception) and iX would reboot the panel when it discovered the program was no longer responding.
Do you have any custom script? If yes, try adding
Code:
try
{
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
blocks around your code to try to determine where you have a bug.
Hopefully this helps.
