Hello Dan,
The Configure Change Detection screen is accessed through the DAQ Assistant. After placing a DAQ Assistant, and selecting a Digital Input task, you will come to the Task Configuration dialog where you can change the channel settings (input range, terminal configuration, etc.), task timing, and task triggering.
In the
Task Timing tab, select one of the hardware timed modes--anything other than 1 Sample (On Demand). Once this is done, the
Clock Type selector under
Advanced Clock Settings, will become active. If you select
Change Detection, a Configure button will appear. Click on that button to get to the Configure Change Detection screen. I hope this helps!
Best regards,
