How to Set Up a Motor Start-Stop Operation in TIA Portal and HMI

 

Industrial automation is an essential aspect of modern engineering, and learning how to create and control motor operations using TIA Portal and HMI is a vital skill for engineers. This blog post will guide you through a step-by-step process to configure a motor start-stop operation with dynamic motor indicators.

What You Will Learn

• How to create a project in TIA Portal.
• Configuring PLC logic for motor control.
• Setting up an HMI interface for start and stop operations.
• Testing the configuration through simulation.

Step 1: Open TIA Portal and Create a New Project

Begin by launching the TIA Portal software. Create a new project by selecting “Create New Project,” entering a suitable name, and choosing a directory. Click Create to proceed.

Step 2: Add Devices

1. Add Controller: Add a new device by selecting a Siemens PLC controller model that matches your setup.
2. Add HMI Device: After adding the controller, select and add an HMI device.
3. Connect Controller and HMI: Establish a connection between the PLC and HMI to enable communication.

Step 3: Configure PLC Logic

1. Add Inputs and Outputs:

   • Insert a normally open (NO) contact for the Start button.
   • Insert a normally closed (NC) contact for the Stop button.
   • Add an output coil for the motor.

2. Create Latch Logic:
   To ensure the motor remains running after pressing the Start button, add a latch circuit in the ladder logic.

Step 4: Design the HMI Interface

1. Add Buttons:

   • Create a Start button and assign an event to set a bit on press and reset the bit on release.
   • Similarly, create a Stop button and configure it to set a bit for stopping the motor and reset the bit on release.

2. Add Motor Signal:

   • Insert a visual indicator (e.g., a circle) for the motor status.
   • Assign the motor tag to the indicator to reflect its state dynamically.

Step 5: Customize Motor Appearance

• Set the motor indicator's appearance to change colors based on its status:
  • Gray for motor OFF (tag value 0).
  • Green for motor ON (tag value 1).

---

Step 6: Compile and Simulate

Compile the entire project to check for errors. Once the compilation is successful, start the simulation:

• Press the Start button and observe the motor indicator turn green, signifying that the motor is running.
• Press the Stop button to stop the motor and watch the indicator revert to gray.

Conclusion

You’ve now successfully configured and simulated a motor start-stop operation using TIA Portal and HMI. This setup is a cornerstone of industrial automation and can be adapted to various applications.

For further learning, experiment with additional HMI functionalities and expand your PLC logic to include safety interlocks or advanced motor control features.
