Issue Details

I am encountering error -200077 at my DAQmx Create Channel VI: 

Error -200077 Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.


Depending on what NI DAQ device your application uses and also I/O type of the channel, certain terminals will only accept certain inputs.

In the body of the error message, Property will let you know what terminal on DAQmx Create Channel is reporting the error, Requested Value indicates what value you are currently attempting to pass, and Possible Values informs what an acceptable input would be. Changing the value to one of the Possible Values will resolve this error. 

If running a Shipping Example, verify the device you are using is supported with that example by checking under its "Requirements" section in the NI Example Finder.

Additional Information

In the above screenshot for a PCI-6110 multifunction DAQ device, the only acceptable value for terminal configuration is pseudodifferential. Error -200077 is occurring due to NRSE being the currently selected value.

Also, same error occurs when the input is not appropriate for a selected DAQmx task.
To resolve the error shown in a screenshot below, suggested input values (Volts or From Custom Scale) should be used for units for analog output (AO) task.
