Issue Details

I created a CI-Pulse Measurement channel in VeriStand's system Explorer windows in order to measure Pulse Width Modulation (PWM) in VeriStand. As hardware for the pulse measurement, I used the PXI-6251 model. However, the following error occurred when deploying VeriStand.

The VeriStand Gateway encountered an error while deploying the System Definition file.
Error -200431 occurred at Project Window.lvlib:Project >> Project Window.lvlib:Command >> NI_VS Workspace ExecutionAPI.lvlib:NI VeriStand - Connect to
Possible reason(s):
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.



VeriStand offers the CI-Pulse Measurement type, which is only supported on X Series DAQ devices. The PXI-6251 you tried to use in VeriStand is the M series DAQ device. Therefore, NI recommends you select another X Series DAQ device to use the CI-Pulse Measurement in VeriStand.
