PID Control Loop — Schneider-ecostruxure Code

A basic PID control loop for regulating a process variable.

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;
