My first thought is to register a formal support request:
https://support.industry.siemens.com/my/ww/en/requests#requests

There is a chance that some user may know what to do.
Please give some more explanation other than "not working". Please give some detailed description of the symptoms and tell us how many is effected.

Good luck!

So the touch functionality does not work - right?

What happens if you connect a USB corded mouse to it?

Which firmware version is the KTP700?..
you should be able to see it in the device settings somewhere.
It may be that you can do a firmware update.

Make sure that there is no place in the device settings (on the HMI) where you can select to not use the touch functionality and have to use the USB mouse.

Don't ask why.. I have a  ' feeling '  that this is hardware related issue. I would suggest strongly that you get the Siemens Rep. where you got the HMI from, to be part of your solution.

Good Luck !!

Hi!!

I thank you, for your collaboration, I tried to connect the mouse and I can access to settings, but I could not find an option that would be useful, I learned a good trick, so thank you so much,

I contacted me with our confiability provider, and like you said, the problem is the hardware, so the provider made use of the guarantee.

I am grateful by your help.

I wish so luck...
