If the first simulator input is off then we turn off the outputs. A second output is used to indicate that the loop is running. When the CPU switch is on and we turn on the first simulator input this will then control the relay output to heat the water in a cup using an immersion heater. If the CPU is not on then all of the digital outputs will be off. If the program is running then the CPU LED light will be on. Our sample program (sketch) will use the CPU switch to turn on and off our program.
Who Else Wants to Learn about On-Off and PID Control? PID Control Arduino Sample Program (Sketch) The following post will use basic math to develop a PID loop in the Click PLC without using the built-in function. Productivity Open P1AM Industrial Arduino PID Control PID Control Math Simply Explained If it is not installed then select the latest version and install. Scroll down until you find the PID by Brett Beauregard. Type in PID on the top line to call up all of the PID functions available in the library.

Our program sketch will use productivity blocks, that will then be verified into the C++ code in the Arduino IDE.
The Arduino PID Library by Brett Beauregard will be used with our productivity open P1AM industrial arduino. A J type thermocouple will be used with the P1-04THM thermocouple temperature and voltage input module. Our immersion heater will be controlled through a relay using time proportional control from our PID output. We will be using an immersion heater in a cup of water to keep the temperature at a constant value. The following links will explain the PID instruction. 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. A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems.
