Issue Details

I have a cRIO-9045, and I would like to get an expansion chassis to use with the CompactRIO (cRIO). Does the expansion chassis have the same DAQmx capabilities as the cRIO-9045?

Solution

The cRIO expansion chassis are not compatible with NI-DAQmx like the cRIO 904x and cRIO 905x controller are. The cRIO expansion chassis only have the FPGA and Scan Interface modes.

However, you can use an Ethernet-enabled CompactDAQ Chassis with the CompactRIO system to expand the chassis and connect to the I/O using NI-DAQmx.
