if you can change brigness via terminal in Linux or Command Line in Windows, of course you can also change via code by using "SysProcessExecuteCommand" function. To try this method you need to apply below modification.
Connect to the target device.
Find and open the runtime configuration file "...codesys/CODESYSControl.cfg" with an editor.
Before [CmpLog], add [SysProcess] and allow line.
