Issue Details

I am trying to make an RT FIFO with a large number of elements.  How big can I make it?

Solution

The size of an RT FIFO is limited by your computer's memory.  The full space of the FIFO must be pre-allocated, and will take up that respective space in memory.

You can see if the size is valid by making a simple VI initializing the FIFO to that size.  If it does not throw an error, it should be a valid configuration.
