Help exactly how?
99.97% of all 'Scaling' problems are caused by the inability to understand basic math*. You don't NEED to use any special function in a PLC in order to scale one signal to another.
The slope-intercept formula will cover all linear scaling issues:
y = mx + b
x is your input, m is a multiplicative scaling factor, b is a fixed offset, and y is your output.
If the 'function block' isn't working, roll your own.
*the other 0.03% are usually indeed difficult to solve, as they involve non-linear curves or strange response devices. In 99% of those cases though, there is an interface unit that will linearize the result for you.
