it is not possible to use the Any type in self created FBs. This is only possible in FW FBs as they are created in a different way.
There isn't a scaling option as this is a simple "rule of three" math problem.
As for your other questions. We are not really sure what you are talking about. "Scale_R, _W, _DW" & "X-Y Conversion and Y-X Conversion"??
