Error -200220 occurred at DAQmx Create Channel

[cassy]

Hello everybody,

I am an amateur in NI, so excuse me if the answer was simple.

I have a program that generates signals on 4 channels with some delay and all other signal manipulation features. It seemed to work for first 2 times and then suddenly the error like this popped (attached for your reference) in one of those runs. Final goal is to interface these generated signals to a Signal generator and reproduce them on it. (In this experiment the signal generator was not connected, program was run plain)

And this error when cancelled reappears continuosly, in fact the only was to abort the program was to press escape button (for the error window to close) and instantaneously click on the STOP button of the main interface.

Any solutions ??? I reinstalled NI DAQ drivers 8.1 twice (uninstall-install cycle) already going by some of the other posts, no difference. I even installed Labview 8.0 itself twice.

Please let me know as soon as possible.

Bye,
Cassy

Reinstalling NIDAQ device drivers repeatedly will not help

Go to MAX and see what device identifier has been assigned to the DAQ hardware that you are using to generate Analog output in your code.

Now, use this Device ID for assigning channel names in your application while generating analog output. ( for EX, if device identifier is Dev2 on MAX, select channel name as Dev2\ao0 etc)

Since you say you are an amateur, I assume that you are usign DAQ express VI's .

Here, click on the express VI icon in the block diagram and Update your channels list for the MAX Detected/ valid DAQ device

any doubts, do get back
