USL-050-B5 backlight adjust from program

[AleksanderØ]

Hi.

I have a USL-050-B5 that is displaying the HMI on a USC-B5-B1.

I want to control the brightness of the backlight from the program, using a slider in a menu and turning the backlight on and off depending on if the system is started or not, as it is only needed about 2 hours every month, the rest of the time I want it to be dark.

Last time I made a similar project I used a US5-B5-B1, here I used modbus-tcp to read the wanted brightness from the main PLC, and a action to change the brightness on the display,

Do I need to replace the USL with a US5 to get this function?

Dear AleksanderØ,
You cannot adjust the USL backlight from program/application because he do not have one. You can adjust the USL backlight  manually from the configuration menu ("UniApps style").
