hi guys,

i have analog 4-20 mA sensor, sesor output is not linear. i have the table for current versus output value but it has 300 values for 4-20 mA, since it is not linear i have to enter each value and its cooresponding output but it will take forever to do it 300 times,

whats the easiest way to do it ?

i thought doing it in SCL would be easier but i have no experince in SCL.. so if thats the way to go i could spend some time to learn it

example:

4mA = 5530 integer = 1 bar

5mA = 6920 integer = 2 bar

6mA = 8300 integer = 5 bar

7mA = 9700 integer = 6 bar

Displaying values from a lookup table based on Analog input. (s7-1200)

I hope this helps,
