Acquisition with Analog Triggering on a CompactDAQ - Falling slope does not appear to work

Hi,

 

I have been trying out the Acquisition with Analog Triggering on a CompactDAQ example without the AO generation part.

 

I am using cDAQ9174 and NI9205 module.

 

My setup is using Grounded Differential Signal, connecting

- a 10k resistor across AI0 and AI8

- AI8 to COM.

- COM to supply -ve

- AI0 to supply +9V via switch.

 

With this set up what I have observed is that whether I set the trigger 'slope' to 'Rising' or 'Falling', the VI is always triggered on rising edge (ie when the switch is pressed)

 

Is my setup that is cause the VI to always trigger on rising edge even if I select slope as 'falling'?

 

if so, what changes should I make so that it can trigger on Falling edge (ie when switch is release) as well?

Hey Sherzaad,

 

Would you be able to share your VI with us? We will then be able to have a quick look at it and see if we can make any recommendations.

 

Best,

Jelmer
