Welcome to the PLC Programming Fundamentals course by AYE Tech Hub. In this course, you will learn how to program Siemens S7 PLCs from scratch, covering everything from hardware setup to complex automation programs.

This lesson introduces you to what a Programmable Logic Controller (PLC) is, how it works, and why it is the backbone of modern industrial automation systems.

What You'll Learn

• What is a PLC and how does it work
• PLC hardware components (CPU, I/O modules, power supply)
• The PLC scan cycle: Input → Process → Output
• Siemens SIMATIC S7-300 and S7-400 overview
• Introduction to TIA Portal programming software
