PID Control Single Channel

[barbara tiseo]

Hi,

I’m using the “ PID Control Single Channel “ example (example\DAQmx\Control ).

I’m generating un external signal (a sine wave) by un external source and the signal is acquired from the Input Channel of a DAQ (NI USB-4431).

Un error occurred at the property node  (code -200077, please, see the attached file).

The suggestion is to select “the onboard clock” on the input channel, so I did it…but I’ve still got the same error.

Please..if you have any suggestion it would be very helpuful.......

thanks

Barbara
