Error 10401:
"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."
This error is usually because the device number you are using is invalid. Make sure you are using the correct device number, and check to see if the device you are using is supported by Traditional DAQ (DIG_Prt_Config is a Traditional DAQ function). My hunch is that you are using an M Series device which is not supported by Traditional DAQ.
If you need more help, you might want to post:
1) DAQ Device
2) NI-DAQ driver version
3) Programming Language
4) Program you are trying to use
