I want to increase the brightness by 10 every time we press the button. I tried creating a tag and scripting it in VB.. However there is no Change in the brightness. May be I am using the wrong logic or commands .Can anyone guide me regarding this ?

If you want to use a script for the job, try using: SetBrightnessValue. Otherwise i would do it inside the PLC logic, because you can define a PLC tag to give the brightness value between 10-100%.
