Using NI-9217 with cRIO-9081

How do you configure a NI-9217 in LabVIEW FPGA.  In LabVIEW and LabWindows you would use DAQmxCreateAIRTDChan to setup the RTD Type, Resistance Configuration and other parameters.

 

Thanks

You can find examples of NI-9217 in NI example finder.

Yes I know about the NI example finder.   But they are all for LabVIEW or LabWindows.  I am using LabVIEW FPGA.  I didn't think you could use standard LabVIEW NI-DAQmx libraries with LabVIEW FPGA.  Can you?

Hello Paul,

 

Have you take a look at the following documentation:

 

National Instruments Online Resource Title (0): Taking Your First Measurement in LabVIEW FPGA (Data Logging)

 

http://www.ni.com/tutorial/54219/en/ 

 

National Instruments Online Resource Title (1): Advanced Data Acquisition Techniques With NI R Series

 

http://www.ni.com/white-paper/2993/en/

 

The resource (0) is the exact application that you need and the (1) is in case you have other cards need an extra step to function.

 

I hope you have a good one!!!

JKarma,

 

Thanks.  I have been doing FPGA programming for about two years using NI-9201, NI-9208, NI-9403 and NI-9485.  This is the first project that I have a NI-9217 module.  I have used them before in LabWindows and  you usually have to configure them.  Mainly the RTD Type, Resistance Configuration (2, 3 or 4 wire) and the Current Excitation Source (Internal or External).

 

I do not see any method or property where those settings can be configured.

Hi Paul,

 

have you tried to check the module properties in the FPGA part of your LabVIEW project?

Best regards,

Yes I did.  All you get is the Name Type, Location, Calibration Mode, and Conversion Time.

Hi Paul,

 

Oh, as I'm on vacation now you need to wait for two weeks before I get back to work to check that with a real cRIO.

I mainly use the 9217 with PT100, 4-wire, internal excitation. You can read the resistance value and apply any calculation you want...

Best regards,
GerdW

I have solved my issue.  I made the assumption that the tech wiring the 9217 knew how to read a schematic.  He missed wired the cable on all 5 of the RTDs.  Once I re-wired I get real values.

 

Thanks for the help.
