Dear Support team,
I have the Unistream US5-B10-B1 OPLC. The factory default touch screen calibration is bad, hence I used the Touch Screen Calibration command from the Uniapps menu. It usually worked well, however on this peace of hardware after touching all the 5 points, it writes "Calibration Failed" and recommends to do it again or restart...I have tried it sereral times with the same result. Any recommendations?
Thank you,
Best regards,
Martin Sirovy.
