Normally, the built-in backlight brightness to be used for a part is set in the Part Feeding Configuration dialog. If changes to brightness are required at runtime, you can use this command to change it.
Cannot be executed from a virtual controller or command window.

KEY POINTS

---

The brightness can be set as a percentage in the range of 0 to 100%, but for IF-240, the actual minimum brightness will be limited to 25%, even if you set the brightness below 25%. This is because uniform brightness cannot be obtained below a certain degree.

If you would like 0% backlight brightness, use the PF_Backlight statement to turn off the backlight.
