regarding USB DAQ 6009

[Samurai555]

hai,this is praveen

i am new to DAQ implementation.

i have been using USB DAQ6009 for the past one week and applying basic concepts on it

like writing to port ,reading to port and simultaneously writing and reading th analog data. There was no error

when i was working last week but now it is giving error saying "Error -50103 occurred at DAQmx Read (Analog DBL 1Chan 1Samp).vi:1". this error i am getting when both write and read operation done simultaneously.

 i am sending the vi pls help me out.

Hi,

Your VI cannot work properly : the while loop is not in a right position. You create the tasks at each loop, but it is not necessary to do that each time ... maybe you can open some examples (help menu / find examples ... ) to show you the correct diagram to acquire and write continously.

Bye

Hi Praveen,

The error that you are receiving is due to the resource being reserved. From your code this is most likely caused by not clearing the AI voltage task at the end of your program. Below is a screenshot of how your program could be laid out. It should be noted that this example does not configure the sample clock therefore the default sample clock will be used. I hope this helps!!
