PID Control Loop

VAR
    SP : REAL;
    PV : REAL;
    CV : REAL;
    Kp : REAL := 1.0;
    Ki : REAL := 0.1;
    Kd : REAL := 0.01;
    e_prev : REAL := 0;
    i_sum : REAL := 0;
END_VAR
CV := Kp*(SP-PV) + Ki*i_sum + Kd*(PV - e_prev);
i_sum := i_sum + (SP-PV);
e_prev := PV;

A basic PID control loop for regulating a process variable.

Let’s Try →

Conditional Valve Control

IF SensorInput THEN
    ValveOutput := TRUE;
ELSE
    ValveOutput := FALSE;
END_IF;

Open or close a valve based on a sensor input using structured text.

Let’s Try →

Array Summation Example

Sum := 0;
FOR i := 0 TO ArraySize-1 DO
    Sum := Sum + DataArray[i];
END_FOR;

Calculate the sum of an array of values in EcoStruxure Process Expert.
