Programmable Logic Controllers Principles And Applications ((better)) (EXTENDED – 2027)

🔹 Imagine a tank filling system. A PLC reads a level sensor (Input), decides the valve should close (Logic), and de-energizes the solenoid (Output). This happens in milliseconds , reliably, 24/7/365.

The physical connection points for sensors (inputs) and actuators (outputs). 🔹 Imagine a tank filling system

Based on the results of the program scan, the PLC updates the status of the output devices. This could mean turning on a motor, actuating a hydraulic valve, or triggering an alarm light. decides the valve should close (Logic)
