is my DAQmx channel property node missing RTD?

[GregFreeman]

Should RTD be available in the menu shown? I do not have an RTD hooked up right now; could this be the problem? However, I don't have a thermistor or a thermocouple and those options show up. I am trying to set A, B, C and R0 programmatically.

Hi Greg,

By default, DAQmx filters out properties that aren't supported on the installed devices. So if your device doesn't support RTD channels, then this is perfectly normal.

However, one of your previous threads was about the USB-6009, so I tried it with that. The 6009 supports RTD channels but the property filtering info for the 6009 is missing the RTD properties, which is a bug. I filed CAR #295521 about it.

The workaround is to set the property node filtering to "Show All Attributes": Missing Properties in DAQmx Property Nodes

Thanks, Brad. I'm just using the 6009 for testing because I have it available in-house. Ultimately this code will be used with scxi. But this is very helpful since I am developing using DAQmx without the hardware attached, and. I'm sure this is not the last time I will be doing this. Thanks again!

Another way to test your code without the hardware is to configure simulated devices in MAX. With simulated SCXI, you can verify that your program's channel/timing settings are compatible with the SCXI modules that you will be deploying. Using the 6009 as a stand-in for SCXI has different advantages, such as reading/writing real data, waiting for real triggers, etc.
