Error -200431, DAQmx Create Channel (AI-Voltage-Custom with Excitation).vi

[T.Knox]

Where is "DAQmx Create Channel (AI-Voltage-Custom with Excitation).vi" gone?

I tried to use this VI for force measurement with a NI PXI-4472. It responds with Error -200431, ... You Have Requested: More:Voltage:Custom with Excitation, You Can Select: Voltage, Sound Pressure:Microphone, ...

It seems for me to be an internal error of this VI, LabView Version is 8.6.1

Hi T.Knox,

error -200431 is a measurement type error:

"Error -200431 occurred at an unidentified location. Possible reason(s):

Measurements: Selected physical channel does not support the measurement type required by the virtual channel you are

creating. Create a channel of a measurement type that is supported by the physical channel, or select a physical channel

that supports the measurement type."

The PXI-4472 (8 Inputs, 24-Bit Dynamic Signal Acquisition module for sound and vibration measurement) is the wrong device

for force measurement.

The PXI-4472 (https://www.ni.com/en-us/support/model.pxi-4472.html) isn't listed as supported device for force measurement

there!

I hope this information helps you!

Hi Suse,

thanks for your reply.

It's the right device but the wrong VI.

PXI-4472 is an excellent device for dynamic force measurement using quarz sensors. I intended to use the (AI-Voltage-custom with Excitation).vi to configure the input and IEPE-excitation, but got the error code. I now succeded using the pure (AI-Voltage).vi configuring the input and IEPE using the DAQmx-channel property node.

On the other hand I tried the (AI-Voltage-Custom with Excitation).vi with an appropriate simulated PXI-4220 device, no error.
