Simple program to transfer 0-5 volt signal to solar radiation data.

[Alaa1999]

Hello, I am trying to build code to acquire solar radiation from a pyranometer using NI-CompactRio and LabVIEW; can you please help me with that? 

I am trying DAQ Assistant, but it gives me this, as shown in the attached picture.

Thanks in advance.

Why do you want to use the DAQAssistent when you already use a IO node from the ScanEngine of the cRIO?

Which cRIO do you use? Does it even support DAQmx?

Did you check the example projects coming with LabVIEW (for cRIO RealTime applications)?

On top of what GerdW said, don't get hung up on the fact that it's a pyrometer measuring solar radiation. 

All you are doing is reading an analog voltage and then scaling it to Watts per square Meter.

Search the examples for your Compact RIO device, I am sure the is a simple DC voltage measuring example.

The documentation for your pyrometer should give you the proper scaling factor to convert that DC voltage to W/M^2.
