Solution
The programming mode setting is module-based, meaning you can only use a single programming mode (either FPGA, Real-Time Scan Mode, or Real-Time NI-DAQmx Mode) per module.
However, you can use different programming modes for each module in the chassis. For example, if you have two NI-9232 modules installed in a single CompactRIO chassis, you can assign a different programming mode to each NI-9232 module.
Programming modes can be set in NI MAX or through the LabVIEW project.
