In Classicladder the halpin "classicladder.0.floatin-00" is %IF0, not %IW0.
%IW0 would be the halpin "classicladder.0.s32in-00".
It is a little confusing since Classicladder doesn't really do floats internally, but it still has float pins externally. This saves having to convert halpins to S32, but you have to remember that all these floats are converted to S32 in CL and are seperate variables from the S32 word variables.
