CDAQ 9229 configure for independan​t channel measuremen​t

Question

I have a need to use the cDAQ 9229 to make 3 measurements using 3 separate channels at different times, but when I try to configurre the channels independantly and use them to make a measurement.
My configuration is (pseudo):
Chan1: Create Chan "Dev1/ai0",commit,start_task,read,stop,clear.
Chan2: Create Chan "Dev1/ai1",commit,start_task,read,stop,clear.
Chan3: Create Chan "Dev1/ai2",commit,start_task,read,stop,clear.
 The First CHannel Works, but when the second gets to commit, I get an error saying the following.
"NI Platform Services:  The specified resource is reserved. The operation could not be completed as specified."
Please help.

Answer 1

If you have truly stopped and cleared the previous task, you will not get the error. Post your actual LabVIEW code so someone can look at it.
Your alternative, as you must have seen when you searched for the error, is to simply read all channels.
