How to Configure a PID Controller in TIA Portal

How to Configure a PID Controller in TIA Portal

Modern process and manufacturing plants are always trying to find ways to operate at higher efficiency and productivity. Better formulations, more reliable equipment, and better process control are some ways that manufacturing facilities can reach peak performance.

In other RealPars videos, we learned that proper sensor calibration yields more accurate process measurements, which in turn, makes “good control” of the process possible, when “good control” is realized, then the process has the best chance of running efficiently and safely.

In this course, we will learn how to achieve “good” control of the process by learning:
- What a process controller is and why it is important,
- How a process reacts to a change in the output of the controller,
- How we can model the process using a First Order Process with Dead Time equation,
- What Proportional, Integral, Derivative, or PID control is,
- How to configure a PID controller in TIA Portal, and
- How to tune a PID controller to give the best control action.
