DAY-1: Introduction to PLCs and basic Programming

    • What is a PLC?
    • Definition and basic principles
    • Comparison between traditional relay logic and PLCs
    • Common PLC applications in industries (e.g., manufacturing, process control)
    • PLC Components Overview
    • Main parts: CPU, I/O modules, Power supply
    • Input devices: sensors, switches
    • Output devices: motors, lights, actuators
    • Basic PLC Programming
    • Introduction to Ladder Logic (LD)
    • Symbols used in Ladder Logic (contacts, coils, relays)
    • Basic program structure (rungs and branches)
    • Setting up a PLC System
    • Connecting and powering up the PLC
    • Introduction to the PLC programming software (e.g., Siemens TIA Portal, Allen-Bradley)
    • Basic I/O configuration (assigning input/output devices)
    • Basic Ladder Logic Program
    • Writing a simple on/off control program (e.g., Start/Stop button controlling a light)
    • Simulating the program using the PLC software
    • Downloading and testing the program on the PLC

DAY-2: Working with Inputs, Outputs, and Basic Control Logic

    • Digital Inputs and Outputs
    • Types of digital inputs and outputs (e.g., push buttons, switches, relays)
    • How to use digital I/O in ladder logic programs
    • Basic Control Functions
    • NO (Normally Open) and NC (Normally Closed) contacts
    • Using a Start button to turn on a light, and a Stop button to turn it off
    • Introduction to contacts and coils in Ladder Logic
    • Introduction to Timers
    • Explanation of timers (ON Delay and OFF Delay)
    • Basic applications of timers (e.g., controlling lights with a delay)
    • Working with Digital Inputs and Outputs
    • Program to control a light with a start/stop button
    • Implementing a simple timer delay (e.g., turning on a light for 10 seconds)
    • Basic Ladder Logic Programming
    • Building simple ladder diagrams using push buttons, lights, and timers
    • Simulating and testing the programs on the PLC
