REMEDIAL PLC SUKMA RAMADHANI

Summary

In this video, Sukma Ramadani from class 11 Allen 4 explains a PLC circuit designed to control a cylinder and LED lights. The process involves using push buttons to start and stop the system, with timers and counters controlling various outputs like the cylinder and LEDs. The program runs through multiple stages, including activation of a memory, triggering a counter, and using timers to control the delay and sequence of events. Sukma walks viewers through the setup and demonstrates how the system runs through a cycle of 3 seconds and repeats thrice, concluding with an overview of the process and a system shutdown.

Takeaways

• 😀 The speaker introduces themselves as Sukma Ramadani from class 11 Allen 4 and explains the PLC system project involving a cylinder and LEDs.
• 😀 The system uses various components such as push buttons (Start and Stop) and memory to control the activation and deactivation of the PLC system.
• 😀 The Start button (address 0.00) activates the system, while the Stop button (address 0.01) deactivates it.
• 😀 Memory (address 200.00) plays a crucial role in marking when the system is active and triggering subsequent components.
• 😀 Rung 0 contains the logic for push buttons and memory functions that control the system's start and stop operations.
• 😀 Rung 1 handles the logic for timers (T1, T2) and counter (C00), which manage delays and cycles within the PLC program.
• 😀 The system operates in a sequence where Timer 1 delays the activation of Cylinder A+ for 3 seconds, and then LED 1 turns on.
• 😀 Once Timer 2 completes, Cylinder Amin moves backward, and LED 2 turns on.
• 😀 The Counter (C00) tracks the number of cycles, and after completing three cycles, the system resets.
• 😀 The speaker demonstrates the program's function by showing the LEDs blinking every 3 seconds for 3 repetitions, after which the system deactivates.
• 😀 The speaker concludes the presentation by apologizing for any mistakes and offering a formal closing greeting.

Q & A

What is the main objective of the PLC system described in the transcript?

The main objective of the PLC system is to control a cylinder and LED based on a sequence of operations, utilizing start/stop buttons, timers, counters, and memory addresses.

How does the start button in the system function?

The start button is used to activate the system. It is assigned to memory address 0.00, and when pressed, it triggers the system to begin its operation.

What does the stop button do in the PLC setup?

The stop button, assigned to memory address 0.01, is used to turn off or deactivate the system.

What is the role of the memory in this PLC program?

The memory in this program stores the status of the system. For example, memory at address 200.00 is used to indicate when the system is active.

What is the purpose of the counter (C001) in the system?

The counter (C001) keeps track of the number of cycles the system goes through, counting how many times the system activates and deactivates.

How are the timers (T1, T2, T3) used in this system?

Timers are used to create delays between actions. For example, T1 and T2 manage the delays before the cylinder A+ and LED 1 are activated, while T3 is used for a longer delay, possibly marking the total cycle time.

What happens when Timer 1 reaches its preset value?

When Timer 1 reaches its preset value (3 seconds), it triggers the activation of Cylinder A+.

How does the system handle the activation of LED 1?

LED 1 is activated after Cylinder A+ is triggered. It lights up as a visual indicator that Cylinder A+ has been activated.

What happens after Timer 2 completes its cycle?

Once Timer 2 completes its cycle, Cylinder Amin is activated to move in the reverse direction, and LED 2 is turned on.

What is the function of the system when the counter reaches 3 cycles?

When the counter reaches 3 cycles, the system stops. This is because the counter is set to count up to 3 activations before halting the program.
