This online PLC Basic training class is designed to provide strong fundamentals of industrial automation through structured theory and practical learning. The course begins with an introduction to PLC concepts, explaining why PLCs are used in industry and how they have replaced conventional relay logic systems. Real industrial examples are used to help learners clearly understand automation principles and control logic.

The class covers PLC applications in various industries along with a detailed overview of PLC hardware, including CPU, power supply, and input/output modules. Students learn how digital inputs and outputs interact with field devices such as sensors, push buttons, contactors, and solenoid valves. Basic analog concepts are also introduced, focusing on standard industrial signals like 4–20 mA and 0–10 V used for process measurement and control.

Programming is taught through live online sessions using Ladder Logic (LD) and Function Block Diagram (FBD) as per IEC industrial standards. Emphasis is placed on hands-on practice, online simulation, testing, and troubleshooting. Each module includes practical exercises and test project creation, enabling students to develop, test, and validate PLC programs confidently, preparing them for real-world industrial automation environments.
