When do we use real time labview module and where do we use fpga module?
couldnt find it anywhere..
help is appreciated

When dealing with cRIO, I use both. With the projects I have had lately, I have found that I can get around 90% of my controller functionality in the FPGA (data acquisition, control, limit checks, filtering, etc). My RT has mostly been for data logging and passing data to the Windows computer (which has a GUI application).

Just for clarity's sake, the FPGA can also do floating point math. It's just limited to the SGL data type. It'll use more fabric than the fixed point calculations. But, if you have enough space there's never the need to optimize by moving to FXP.
As others have said, RT is for your OS type interactions. FPGA is for high speed calculations/data acquisition. They increase in value when used together.
