Jazz UA24 - Signed Bits to Numeric + Linearization

Sign in to follow this  

About This File

You have an 8 bit signed magnitude input value coming into the PLC via I0-7.

And you want it to scale so that:

11111111b = -127d = -10V

01111111b = +127d = +10V

If the above assumption is correct, you can use two linearization functions.

But first you will need to only use the function “I to MI” on inputs 1-7.

Before the linearization function, use input 0 (the sign bit) as a condition to enable the positive or negative linearization function.
