I pretty sure this has been covered before, but I need to ask. I have an Unwinding roll of paper and I want to display the diameter of the roll and the length of paper remaining. I have 2 signals available to do the calculation from.
The first signal is 4-20 mA based on line speed (1500 fpm max) and the other signal is a 4-20mA based on the rotational speed of the roll. I need to program the math expression in a Do-More program. Can anyone help me with the math? Thank you.
