DAQ Error -200284

[rtck]

Hi,

We are knew to Labview but we have been given a Labview program that previosuly worked. The program sends signals to resistors to turn them on and off to measure a voltage of a power supply.

We keep getting this error when we try to run the programm, is the issue with our program or with the circuit?

Thank you

What is your timeout?  How many samples are you trying to collect?  What is the sampling rate?  Can you just post the VI itself?

And for future reference, post images as jpg or png.  There are many people who don't want to open up Word documents.

Are you by chance using a USB DAQ on Windows 7? Was the machine that it was previously working on XP? Check out this KB from NI. You'll have to update DAQmx to 9.4 and set the property node mentioned in this post.

The time out is 30 seconds.

We are trying to collect 14 samples. I'm not sure what the sampling rate is?

Is one of these attachments the VI?

Thank you

Hi Charles,

We are running on Windows XP. The macine has always been working on XP.

Do you think it could be a problem with one of the USB DAQ leads?

Thank you
