Dear all,
I sat all day here trying to figure out what is wrong with my Labwindows data acquisition systems. To be specific, I created multiple channel data acqusition (7 signals from 6 different instruments) using LabWindows 2013 on a Win7 OS. Five signals are taking at the same time, and another two needs to be done separately. To realize, I created two DAQmxCreateAIVoltage tasks. However, when running, it turns out the task created second did not give any data other than zeros. I switched the creating sequence of the two tasks. It turns out the task created second always do not give any signal.
My question is, it is allowed to create two data acquistion taskhandles at the same time in one single application? If not, is there a way to circumvent it?
Thank you for your suggestions in advance.
