26. ABB AC800M PLC Basic Start Up

Introduction

This tutorial guides you through the basic startup process of the ABB AC800M PLC. Understanding how to initialize and configure this programmable logic controller is essential for automation engineers and technicians. This step-by-step guide will help you set up the PLC effectively, ensuring a smooth start to your automation projects.

Step 1: Gather Necessary Equipment

Before starting, ensure you have the following items on hand:

• ABB AC800M PLC unit
• Power supply compatible with the PLC
• Ethernet cable for network connection
• Programming software (e.g., Control Builder)
• Computer for configuration

Step 2: Connect the Power Supply

To power your ABB AC800M PLC, follow these steps:

1. Check the voltage requirements of your PLC model.
2. Connect the power supply to the appropriate terminals on the PLC.
3. Ensure that the power supply is turned off during the connection process to avoid any electrical hazards.
4. Once securely connected, turn on the power supply.

Step 3: Establish Network Connection

Setting up a network connection is crucial for programming and monitoring the PLC.

1. Use the Ethernet cable to connect the PLC to your computer or network switch.
2. Ensure that the PLC is configured to obtain an IP address, either dynamically via DHCP or statically.
3. Verify the connection by checking the status LEDs on the PLC.

Step 4: Install and Open Programming Software

To program the PLC, you need the appropriate software.

1. Install Control Builder software on your computer if it is not already installed.
2. Launch the Control Builder application.
3. Create a new project and select the appropriate PLC model to start configuring your system.

Step 5: Configure the PLC Settings

Once in Control Builder, configure the PLC settings:

1. Set the IP address and subnet mask according to your network configuration.
2. Define the communication settings (e.g., protocols, baud rates).
3. Save your configuration.

Step 6: Create and Upload Application Program

Now it’s time to create your application program:

1. Use the programming environment to create your desired logic (e.g., ladder logic, function block diagrams).
2. After coding, compile the project to check for errors.
3. Upload the application program to the PLC via the established network connection.

Step 7: Test the PLC Operation

After uploading the program, perform a test to ensure everything operates correctly:

1. Monitor the status of the PLC through the Control Builder interface.
2. Test each input and output to confirm they respond according to your program.
3. Address any issues or errors that may arise during testing.

Conclusion

You've now successfully completed the basic startup procedure for the ABB AC800M PLC. Key points to remember include ensuring proper power and network connections, configuring the PLC settings, and testing the application thoroughly.
