Issue Details

I am trying to run DAQmx code with one of my data acquisition devices and get an Error -200430 at DAQmx Create Channel. Why is this happening?


Error -200430 occurs when the I/O type of the physical channel does not match the I/O type required for the virtual channel you are creating.

To correct this, ensure that the I/O type is properly set in the DAQmx Create Virtual Channel VI to correspond to the I/O the card is designed for.
For example, if you're using a Counter Input I/O Type Virtual Channel and select an Analog Input Physical Channel for the same task, you'll receive this error.
