Hi *LJ,
I tried to take a look at your code, but I was unable to
open all of the parts of your code because there were missing subVIs that you
did not attach to the post. I took a look at
the VIs that you did post and I noticed that except in the AnalogueInput1.vi
you do not clear the DAQmx tasks in your program.
Tip: in the AnalogueInput1.vi you call both a DAQmx Control
Task VI and a DAQmx Clear Task VI. The DAQmx
Clear Task VI will release all reserved resources, so in this case you don’t
need to release resources using the DAQmx Control Task VI.
In general, you should always clear each DAQmx task at the
end of a program. Look through your code
and make sure that for each task you create, you have a corresponding clear
task. If desired, you can call the clear task as the last step in the subVIs
that you have created to configure and read/write to your various inputs and
outputs.
Tip: If you have multiple reads or writes taking place
inside of a while loop you can improve the execution speed of your program if
you configure the task outside the while loop, perform as many reads or writes inside
the while loop, and then at your end of the program clear the task outside of
the while loop.
