The driver interface is not consistent

Using NIDAQmx v7.4

Why does the method DAQmxGetAIRngHigh fail on a simulated PCI-6143 device?
(Requested value is not supported value for this property.)
DAQmxResetAIRngHigh works and is called just before DAQmxGetAIRngHigh.


Why does the method DAQmxGetAIConvRate returns error on a simulated PCI-6110 device?
(Specified property is not supported by the device or is not applicable to the task.)

Hi

The DAQmxGetAIRngHigh function works perfectly on a simulated device on my end. I did receive an error when running a modified CVI example because the default requested min and max values were -10V and +10V. Are you sure you weren't seeing this error instead? I. Make sure that you change the input limits to +-5V to avoid the error we're discussing.

The DAQmxGetAIConvRate fails on a PCI-6110 (and all S Series devices) because there is no convert clock. The S series boards have independent ADCs for each channel and therefore no convert clock.

Thanks

This reply looks very familiar Meister. 😉
