AB Micrologic 1500 Adding Floating Points

Can anyone here refresh my mind on how to perform addition on 33 floating point variables? F8:1 to F8:32. the result should be in F8:0

Here's a simple way of doing it assuming you want to sum them every scan. If not, you can always add a timer so the logic only runs when you need it.

My suggestion would be to just make 31 rungs:
F8:0 = 0.0
F8:0 = F8:1 + F8:2
F8:0 = F8:0 + F8:3
...
F8:0 = F8:0 + F8:32

Put them all in a subroutine and they won't get in your way. I've tried the JMP/LBL thing before, yes it is compact but it can adversely affect your scan time.
