AleksanderØ Posted August 3, 2020 Report Share Posted August 3, 2020 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?

NoamM Posted August 26, 2020 Report Share Posted August 26, 2020 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"). Quote Link to comment Share on other sites More sharing options...
