PLCs process analog variables like temperature, pressure, and flow rates. By using Proportional-Integral-Derivative (PID) loops, a PLC can precisely throttle a control valve to maintain a steady chemical reaction temperature. Food and Beverage Packaging

In automotive assembly, PLCs coordinate robotic arms, manage conveyer belt speeds, and verify quality control checks via vision sensors. They ensure that parts move seamlessly through the station without collisions. Chemical and Petrochemical Processing PLCs process analog variables like temperature

Before the era of digital PDFs and online video courses, John W. Webb’s textbook was the definitive roadmap for understanding PLCs. Even today, it holds a top position for several reasons: PLCs coordinate robotic arms
