📌 Parts Explanation (Easy Words)
1️⃣ Power Supply
PLC ko electricity deta hai
Usually 24V DC / 230V AC
2️⃣ Input Module
Field devices se signal leta hai
Example: Switch, Sensor, Push Button
3️⃣ CPU (Brain of PLC)
Program run karta hai
Input read → logic apply → output decide
4️⃣ Memory
Program & data store karta hai
5️⃣ Output Module
CPU ke order par devices chalata hai
Example: Motor, Lamp, Relay, Buzzer
🔁 PLC Working (One Line)
Input → Program Logic → Output
