Introduction

This tutorial provides a step-by-step guide on how to facilitate data exchange between a Delta DVP12-SE PLC and other PLCs via Ethernet. This process is essential for seamless communication between devices in industrial automation and control systems. Understanding how to set up and configure this connection will enhance your PLC programming skills and improve system integration.

Step 1: Prepare Your Hardware

  • Ensure that you have the following components ready:
    • Delta DVP12-SE PLC
    • Ethernet cables
    • Other PLCs that you wish to connect
    • A power source for the PLCs
  • Confirm that all devices are powered on and properly connected through the Ethernet cables.

Step 2: Configure the Delta DVP12-SE PLC

  • Access the programming software for the Delta DVP12-SE.
  • Set the Ethernet parameters:
    • Navigate to the 'Network' settings in the software.
    • Assign an IP address to the DVP12-SE PLC. For example, use 192.168.1.10.
    • Set the subnet mask, typically 255.255.255.0.
    • Configure the gateway if necessary.
  • Save the settings and download them to the PLC.

Step 3: Configure the Other PLCs

  • Access the programming software for the other PLCs.
  • Assign unique IP addresses to each PLC in the same subnet as the Delta DVP12-SE. For example:
    • PLC 1: 192.168.1.11
    • PLC 2: 192.168.1.12
  • Ensure the subnet mask is consistent with the Delta DVP12-SE settings.
  • Save and download the settings to the other PLCs.

Step 4: Establish Communication Protocol

  • Choose a communication protocol suitable for your needs (e.g., Ethernet/IP, Modbus TCP).
  • In the Delta DVP12-SE programming software, configure the communication settings:
    • Select the appropriate protocol.
    • Define the data points (registers) you want to exchange.
    • Set up the read and write commands as needed.

Step 5: Test the Connection

  • Use the programming software to monitor the communication status.
  • Check for any error messages or connection issues.
  • Conduct a simple data exchange test:
    • Send a command from the DVP12-SE to the other PLC and verify the response.
  • Adjust settings if any issues are detected.

Conclusion

In this tutorial, we outlined the necessary steps to set up data exchange between a Delta DVP12-SE PLC and other PLCs via Ethernet. By preparing your hardware, configuring the PLCs’ network settings, establishing the communication protocol, and testing the connection, you can ensure effective communication in your automation projects. As a next step, explore advanced topics such as error handling and data logging to further enhance your PLC applications.
