In this video, I explain the Interlocking concept in PLC programming using a ladder logic diagram and TIA Portal simulation.

🔹 What is Interlocking?
Interlocking ensures that when one motor is running, the other motor cannot start, improving safety and preventing damage.

🔹 Topics Covered:
• Two-motor interlocking ladder logic
• Start/Stop push buttons logic
• Using motor output as NC contact for interlocking
• How Motor-1 blocks Motor-2 and vice versa
• Real-time simulation in TIA Portal
• HMI motor status indication (Green ON status)

🔹 Logic Explanation:
• Motor-1 ON → Motor-2 circuit opens
• Motor-2 can start only after Motor-1 stops
• Same logic applied in reverse direction
This concept is very important for PLC interviews, industrial automation, and safety circuits.
