cdaq pwm

[bassinbc]

Using cDAQ 9172, modules 9401 and 9205.

I get the following error when running.

Error -200077 occurred at Property Node DAQmx Timing (arg 3) stating I can't use Hardware Timed Single Point.

What can I do to get this to work on cDAQ 9172?

Thanks for using NI forums.  I will take a look at your code and see what I come up with.  In the meantime, what slots are your modules in?

9401 in slot 5 and 9205 in slot 1. The attached vi works, i'm not sure if I should be using hardware timing. The objective of this code is to read a voltage in and vary the pulse width at a set frequency. I am not sure if there should be some sync between the AI and counter out.

You do not have to use hardware timing in this case.  Hardware timing is for more Control Design and Simulation applications.  If your VI works then I would say leave it as it is.  One thing you could do is synchronize the start triggers of your analog input and counter output (like what you had in your first VI).  Please let me know if you have any further questions.

Have a nice day,
