difference between real time module and fpga module

[Neil.Pate]

Hi experts,

I was wondering if someone could tell me (in a nutshell) the difference between the FPGA module and the real-time module.

My understanding is the FPGA module facilitates LV code that can then be targeted at specific RIO boards, I have used this a little in the past.

The real-time module I am a bit more unsure about, all I know is that it allows for creation of a "real-time" i.e. time deterministic environment.

My application is this: I wish to have several control loops running on two RIO boards, with the host PC mainly being used for logging of data and UI business. So as far as I can see I do not need RT on the host (Win XP should be fine).

Do I need the RT module???

Additional info: the RIO boards will probably be 2x PCI-7833R

You are correct.  In the scenario you describe, you will not need LabVIEW RT. LabVIEW RT is used to create deterministic execution on specific intel targets like the PXI-8106 and PXI-8108.  You can still use floating point and strings on RT.

OK thanks, I was hoping somebody would say this!
