Automatismo cancello con PLC e chiusura automatica temporizzata simulazione CADeSIMU

Summary

The video tutorial demonstrates the movement control of an automatic gate using a PLC (Programmable Logic Controller) and a simulation program. The presenter walks through the power circuit setup, explaining the forward and reverse motion of the gate, manual and automatic operations, and the use of limit switches and timers for opening and closing. The flashing light indicates movement, and an emergency stop button is also highlighted. The simulation showcases both manual and timed control functions, ensuring clear visualization of the gate's operation with the help of the PLC system.

Takeaways

• 🔧 The video explains the operation of an automatic gate system controlled by a PLC.
• 📊 The power scheme for the gate movement remains the same as before, using resistive actuators and two limit switches for open and close positions.
• 🔄 The system allows manual operation for opening and closing the gate, along with automatic timed closure using a timer.
• 💡 The system features a flashing light that signals movement during both opening and closing operations.
• ⚙️ The motor can move forward and backward for opening and closing, and a selector switch and magneto-thermal circuit breaker are included.
• 🚦 The PLC controls two coils for forward and reverse movement of the motor, ensuring gate movement.
• ⏳ The automatic closure is activated after a short delay, using a timer set to three seconds once the gate reaches full open position.
• 🛑 An emergency stop button is included to immediately halt the gate movement if needed.
• 📋 The video also shows how the wiring and power supply to the PLC are connected for the system to function.
• 📱 The speaker describes potential manual interventions and highlights how the system can be modified if necessary.

Q & A

What is the main focus of the video?

The video focuses on the movement of an automatic gate controlled by a PLC (Programmable Logic Controller) and demonstrates its operation using a simulation program.

What type of actuator is used in the gate system?

A resistive-type electric actuator is used for the gate system, which interacts with two limit switches for gate movement control.

What are the functions of the two limit switches mentioned in the video?

The two limit switches indicate when the gate is fully open or fully closed, allowing the system to control the movement accordingly.

What components are connected to the PLC for controlling the gate?

The components connected to the PLC include two coils for forward and reverse movement of the gate motor, a yellow warning lamp, manual open/close buttons, and a timer for automatic closing.

How is the opening and closing of the gate initiated manually?

The gate can be opened or closed manually by pressing specific buttons (S1 for open and S2 for close), or by pressing the stop button (S3) for emergency stops.

What role does the timer play in the system?

The timer initiates the automatic closing of the gate after a few seconds once it reaches the fully open position.

What safety feature is included in the gate control system?

The system includes an emergency stop button (S3) that can immediately halt the gate movement if needed.

What is the purpose of the yellow warning lamp in the gate system?

The yellow warning lamp blinks intermittently to signal gate movement, providing a visual indication whenever the gate is in operation.

How is the power supply arranged for the PLC in this gate system?

The PLC is powered by a 24-volt power supply, with P1 and P2 terminals connected to the power line and ground, respectively.

What does the creator suggest about visual clarity during the simulation?

The creator mentions that zooming in during the simulation is challenging due to limitations in the interface, and suggests that viewers might need to adjust their view to better see the details.
