Thank you so much. I think there is a problem with my screen because when I touch the yellow dots, another yellow dots appears. It beocmes a loopand I was trapped in for 5 minutes.
I thought it was my problem at first, and I restarted the PLC.However, it jumped to Enter Password Mode from the calibration mode automatically. With the keyboard, I can see that when I want to enter a number, another number is entered. For example, I want to touch the 9 bouton, the 0 bouton is lighted.
Based on this, I think there is a problem with my screen. Do you have any other ideas about this.
Thank you so much
