Python/C++ Compatibility With cRIO Controllers

I have inherited some NI hardware and I am trying to determine capabilities and limitations of what I have. This is all new to me so excuse any bad assumptions I may have.

 

I am setting up a test environment and I prefer to interface with the hardware through code(Python/C++) and libraries without the use of LabView. Based on my research, it sounds like the major limitation for the hardware I have is that LabView would be required to use the FPGA capabilities. If I am not using the FPGA, then I should be able to the cRio modules via daqMX libraries. Am I interpreting this correctly or is there something I am missing. It looks like the only module I can't use without LabView is the CAN interface. I have other options for my CAN needs so that is not a big deal.

 

I am also assuming that I interface with the 9022/9114 and the 9144 is just connected as a slave?

Thanks,

The only cRIO chassis family that supports DAQmx technology to control the onboard modules are the 904x and the 905x: NI-DAQmx on the CompactRIO - NI

Thanks, does the 904x/905x series have a chassis included? It doesn't list chassis under accessories and shows a chassis in the photos.

In my understanding, 904x/905x are chassis + integrated controllers, you get them as a single unit.

 

For instance, 9045 is an 8-slot chassis with a controller
