Thanks, I probably missed that footnote....

So the logic block can read real in's, but only for timing functions.....

Foxboro "Logic" I guess.....

In fact, the documentation states explicitly:  "Real inputs are supported
only for timing logic operations."

(B0193AX, Rev. S, Section 75.1, footnote 1 at the bottom of the table)

You might want to consider a MATH block if you're looking to minimize block
memory.
