Hi Guys,
I'm detecting HMI user activity/last key pressed by using sysBackLight and it works fine with the actual controller but in the Sim mode sysBackLight stuck at zero.
I'm trying to implement something like below:
>>> IF last key pressed longer than 60secs, show page 1.
Is there a way to make sysBackLight goes > 0 in Sim mode? If not, whats the best way to detect the last key pressed?
Thank you.

Hi you could find a code sampel in the integrated TVDA for large chiller.
It is located in the Global Procedure. In the sample the internal systimer is used to create a timer function to reach the same like with sysBacklight.
