Thanks Kareem.

You make a very good point! I followed your advice, and I did see some problem. I can find the Galil hardware on my old system computer, but I cannot find it in our new one. There is a difference between the two system. The old computer using PCI card, but the new one is connected to computer with ethnet cross cable. Will this be the reason?

Unfortunately, I don't believe I answer this question. Because you are using a third party card, I would contact Galil to understand whether communication via Ethernet is supported by their hardware. In the mean time, you can try installing the PCI card directly into the new system just to make sure that everything works properly with your LabVIEW code. This will allow you to further isolate the source of the problem.

I contact with Galil. It seems like there is some misunderstanding. Their device is just a controller for motors. It doesn't have a data aquisition function, though it has A/D input. I checked our old system, we used NI PCI-6036E. Do you think the error 10401 is related with missing this card? If so, we should definitely need to get this card, right? Thank you so much for your patience and help.

RobinX,

I checked into your error code and it means the following:

"NI-DAQ LV:  The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using the Measurement & Automation Explorer."

If you would like to acquire data, you definitely need a DAQ (data acquisition) card. The PCI-6036E in your old system serves this function. I assume that the VIs that came with your motor controller allow you to integrate it into LabVIEW - enabling control of your motor programmatically (i.e. Via software) through LabVIEW. This, however, would have nothing to do with acquiring any actual data. The DAQ card would handle that responsibility.
