Yes, use SI 9 to adjust the backlight intensity from 0% - 100% and use SB 16 to return the screen backlight to its previous value.
Be careful though, when a user touches a dark screen, any button or control that is there will be activated. I usually load a blank screen when I dim the display to prevent inadvertent activation of some control.
I'm developing a recipes application in a sm43-j-r22.
I want to disable or turn off the display if no control is touched in 5 five minutes in order to improve de durability of te device.
Thescreen must be turn on if the user touch the screen again.
Is this possible?
If the "Burn Upload Project" option was selected when the project was downloaded, then the .vlp file can be extracted. If not, then no. Once you download a new project, the previous project in the PLC is gone forever.
