Step-by-Step Siemens PLC Motor Starter Program in TIA Portal

In this tutorial, we'll guide you through the process of creating a simple motor starter program using Siemens TIA Portal V14. Whether you're new to PLC programming or looking to expand your skills, this step-by-step guide will help you get hands-on with motor control systems and ladder logic programming.

What You’ll Learn:

• How to create a new project in Siemens TIA Portal V14.
• How to add and configure your Siemens S7-1200 PLC.
• Writing a ladder logic program to control the motor.
• Setting up Start/Stop buttons, Overload protection, and Limit switches.
• Simulating the motor starter system in TIA Portal to test and visualize your program.

Key Steps in the Project:

1. Creating a New Project
   Start by creating a new project in TIA Portal and give it a simple name, like "Simple Motor Starter." This helps to organize your work as you move through the program setup.

2. Device Configuration
   We will be working with the S7-1200 PLC. In this step, you will add the device to the project and configure it for your specific motor control needs.

3. Programming the Ladder Logic
   The first rung will handle the basic Start/Stop functionality along with Overload protection and a Limit switch to ensure safe operation.

4. Adding Motor Control and Output LEDs
   The second rung involves latching the motor and connecting an Output LED to provide a visual status when the motor is running.

5. Red LED for Motor Failure
   The third rung will light up a Red LED when the motor fails, providing a clear indication of any issues.

6. Simulation
   Finally, you’ll simulate the entire system in TIA Portal. We’ll show you how to load the program into the simulation environment, test the motor's start/stop operation, and see the LEDs respond to the motor’s status.

Conclusion:

By following these steps, you will have successfully created a basic motor starter program using Siemens TIA Portal. This is an excellent project for those starting out with PLCs or anyone looking to refresh their knowledge of basic motor control systems.
