Hello, I need to build a project with PID function.
The main objective is to work with pressure (sensor is 0-16bar 4-20mA).
If pressure is between 5 and 7bar (7 is set point), I want PID to give scaled values at my analog output.
Pressure <= 5bar = 100%
Pressure > 5bar and < 7bar = scaled values
Pressure >= 7bar = 0%
So actually as I understand, I need need a second set point. The HIGH set point is 7. The LOW set point is 5.
How am I going to give the low set point?
Thanks in advance!!!
