BRX (Do-More) PLC PID with PWM Output

We will now look at the BRX (Do-More) PLC PID with PWM (Pulse Width Modulated) output. A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a minimum. We will be using an immersion heater in a cup of water to keep the temperature at a constant value. Using the Do-More Designer software we will perform an autotune on our PID instruction. Our immersion heater will be controlled through a relay using time proportional control from our PID output. Let’s get started. More information can be obtained on our website.
