Productivity 1000 Series PLC PID Instruction

PID Loop (PID) Instruction (Auto Tuning) 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. The following links will explain the PID instruction. https://www.csimn.com/CSI_pages/PIDforDummies.html http://www.ni.com/white-paper/3782/en/ https://en.wikipedia.org/wiki/PID_controller We will be using an immersion heater in a cup of water to keep the temperature at a constant value. Using the Productivity Suite 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. This includes all of the links mentioned in this video. https://accautomation.ca/productivity-1000-series-plc-pid-instruction Here are some previous posts in this Productivity 1000 PLC Series.
