Issue Details

I am trying to test the modules of my CompactRIO and to do this I am using LabVIEW. I added the cRIO to a LabVIEW project successfully. I created a VI under the CompactRIO chassis and placed a DAQ Assistant function there. 

However when I create a task I see that in the Supported Physical Channels it says: "No supported devices found".  
Why is this happening? How can I test my modules? 

Solution

The DAQ Assistant is part of the NI-DAQmx driver that is not supported by all CompactRIO modules. If you are using one cRIO that does not support DAQmx you will see the message of  "No supported devices found".

To test the modules you can either use the Distributed System Manager or you can program in LabVIEW using either the Scan Interface Mode or the FPGA mode (which require the LabVIEW FPGA module).
