How do I set while loop priority in an RT Field Point application?

I have a vi that I want to run in an FP2010 that contains 2 while loops, one must be Time Critical priority and the other Normal or lower priority.  I will be using RT FIFO to transfer data between the two loops. The Normal loop will be used for communication with a Host PC.
 
How can I set the priorities of these 2 loops?
 
Can I run 2 separate vi's in the FP with each set to a different priority And transfer data between the two with RT FIFO? How?
 
I am using V6.1 and the customer does not want to spend on upgrading.
 
Thanks,
Chris

Chris,
You are on the right track using two separate VIs with different priorities and using RT FIFOs to communicate between the two.  Please see the following tutorial and the related links, one link of which is an example with a zip file containing the RT FIFO VIs for LabVIEW 6.1.
