Hi

I got a really strange problem today. I was running the program which I did before. I didn't change anything in the program, but it's not working now. The error message said "Error -200220 occurred at an identified location Possible reason(s): Device identifier is invalid". At frist, I thought I used the wrong device name,but I checked the device name in the MAX. It was correct,and then I ran a program which used the analog input and output. They all worked find!! Then I tried to use the "NI-DAQmx Base Configuration Utility",the result was the same. All the task of the analog was fine, but when trying to use digital input and put. It said"Error -1 occurred at an unidentified location. Possible reason(s): NI-DAQmx Base was not able to find a device compatible with this task."

I'm sure that my computer is alreay recognise this device, so why this happen?

Thank you!

Hi,

If you are in windows, which it looks like you are (if you are using MAX), then I strongly recommend programming your device with NI-DAQmx, not NI-DAQmx Base.  Having said that, I would guess that your problem is directly related to this KB.

Here is the information about switching the device from DAQmx Base to DAQmx so that it will work with the example that you have been working with the 6008's sucessfully with.

This should give you a device listed under 'NI-DAQmx Devices' where you can perform a DAQmx test on it. Then referencing the device as DevX/aiX should work from within LabVIEW.

I hope this helps, let me know if you have any more questions/problems with this

Thanks for your reply!

Yes, you're right. I have already solved the problem now.  Anyway,thanks again!!
