PLC - Introduction | Programmable logic controllers | Steps towards Automation - 01

The video tutorial provides an in-depth look at Programmable Logic Controllers (PLCs), their components, and their role in automation. It covers the input/output modules, CPU, power supply, and rack, explaining how each part functions within the system. The tutorial also discusses the types of PLCs, programming methods like ladder logic, and the operational steps of PLCs. Additionally, it delves into the history of PLCs, highlighting their evolution from relay logic systems and the contributions of Dick Morley.

What is the role of the Central Processing Unit (CPU) in a PLC?

What historical challenges did PLCs address in industrial automation?

Explain the ladder logic programming and its significance.
