Turn off display in run-time on MD4 controller

mdaigneault 4 years ago in IQANdesign updated 4 years ago 3

I'd like to know if it's possible to disable the MD4 display and backlight during run-time to save power for batery operations. The application we have requires some periods of operation on battery power, and we'd like the controller to stay awake but be in a low-power mode. We believe turning off the display would help extend the duration of time we can operate on a single battery charge.


It would be great if an internal digital could be used to enable/disable the display and backlight, which could be woken another internal digital or a contact with the touch screen.

GOOD, I'M SATISFIED

Reducing the backlight will reduce the current consumption of the MD4, so that is a good idea. 

Under MD4 display pages, there is a property for controlling the backlight with a channel. 




The other option is to use the screen saver options in the display settings. 



Thanks. It would be nice if the screensaver could also be toggled via an internal digital.
