Digital Input Timing

[sky_11]

Hello,

I have an Digital Input signal coming to my Daq, which is 4sec ON and 10sec OFF.

But I would like to compare the 4sec ON, if the high signal was high for more on equal to 2sec, if send a true signal, if it was less then 2sec then a false.

I know i have to use case structure to have true & false conditions, but I dont know how can i check how long the signal was high.

Any help would be appreciated.

Kind regards,

Hi Sky

You can use DAQmx to measure the period of the digital input:

Then just add a case structure for the conditions and the actions

Hope that helps
