Normally, when we press a button on the logo, the screen becomes white and then the backlight will be dimmed after not pressing any buttons. I need in the logic to warn the user of certain events at a time by activating an output plus the red background of the logo using the M29. But when we use M29, even if the M29 is zero the page will be dimmed whether we press the key or not. Please guide me how to modify the Logic to make the display backlight behave as normal when the M29 is zero. Thank you.

Only when a cursor key is pressed in conjunction with the ESC key, ie ESC + cursor key. Then you can put the 4 cursor keys in the program query and on the flag for the white backlight.
