Error: the specified resource is reserved.

Hi all,

I have composed a program that is going to read 4 analog input voltages, however, I get error as shown in the picture.  Basically, Dev1/ai0 thru Dev1/ai3 will be used to get data from. But everytime I run this program, one of the DAQmx reads will light up and the error message will pop up and I am in trouble.

Is there any way I can fix this problem, so that I can read all 4 AIs at the same time?

Thanks a lot in advance.

I guess you did not try to search for this error. It's been asked numerous times.

The answer is simple - don't use 4 separate tasks. Use a single task with multiple channels.

Thank you very much. I think I found the solution!
