Introduction

Siemens HMIs (Human Machine Interfaces) and PLCs (Programmable Logic Controllers) are critical components in industrial automation, providing seamless control and monitoring capabilities. One of the essential aspects of maintaining these devices is the proper configuration of IP addresses. Whether integrating new devices into a network or resolving communication issues, understanding how to change the IP addresses of Siemens HMIs and PLCs is vital for any automation professional.

Understanding Siemens HMI and PLC IP Configuration

In industrial settings, Siemens HMIs and PLCs work together to control and monitor various processes. The IP address is a unique identifier that allows these devices to communicate over a network. Correct IP configuration ensures that the devices can exchange data efficiently, minimizing the risk of communication failures and system downtime.

Consistent management of IP addresses is crucial. It helps in:

  • Avoiding IP conflicts: Ensuring each device has a unique address.
  • Simplifying network troubleshooting: Easier identification of devices on the network.
  • Improving security: Proper IP management helps protect the network from unauthorized access.

Steps to Change the IP Address on Siemens HMI and PLC

Preparation

Before changing the IP addresses, gather the necessary tools and ensure that all current configurations are backed up. This preparation helps in preventing data loss and ensures a smooth transition.

Tools Needed:

  • TIA Portal: The primary software used for configuring Siemens devices.
  • PRONETA Tool: A free tool from Siemens for diagnosing and configuring network devices.
  • Siemens Support Documentation: Provides detailed instructions and troubleshooting tips.

Using TIA Portal to Change IP Addresses

TIA Portal is the main software tool used for programming and configuring Siemens devices. Follow these steps to change the IP addresses using TIA Portal:

  1. Open TIA Portal and Load the Project:
    • Launch TIA Portal and open the project containing the HMI and PLC configurations.
  2. Access Device Configuration:
    • Navigate to the ‘Devices & Networks’ view.
    • Select the HMI or PLC device you wish to configure.
  3. Modify IP Address:
    • Go to the ‘Properties’ tab.
    • Locate the ‘Ethernet addresses’ section.
    • Enter the new IP address and subnet mask.
  4. Save and Download Changes:
    • Save the changes to the project.
    • Download the updated configuration to the device.
  5. Verify Communication:
    • Ensure that the device is communicating correctly with other network devices.
    • Use the ‘Online & Diagnostics’ tool to check device status.

Using the PRONETA Tool

The PRONETA tool is another valuable resource for changing IP addresses on Siemens devices. This tool is particularly useful for diagnosing and configuring devices on a PROFINET network.

Steps to Use PRONETA:

  1. Connect Devices:
    • Connect the PLC and HMI to the network.
  2. Scan Network:
    • Use PRONETA to scan the network for connected devices.
    • Identify the devices by their current IP addresses.
  3. Change IP Addresses:
    • Right-click on the device and select ‘Edit network parameters.’
    • Enter the new IP address and save the changes.
  4. Verify Changes:
    • Ensure that the new IP addresses are correctly assigned and that the devices are communicating properly.

Common Issues and Troubleshooting

Even with careful planning, issues can arise when changing IP addresses. Here are some common problems and their solutions:

Error Codes and Solutions

Error 8092: This error occurs when the IP address change does not address a PROFINET IO device.

  • Solution: Ensure that the correct hardware identifier is used. Verify the device’s settings and retry the configuration.

Ensuring Communication Post-Change

After changing the IP addresses, it is crucial to verify that the devices can communicate correctly:

  • Check Device Status: Use the ‘Online & Diagnostics’ tool in TIA Portal to check if the devices appear online.
  • Ping Test: Use a ping test from the command prompt to ensure the devices respond to network queries.

Expert Tips and Best Practices

Following expert advice and best practices can help ensure a successful IP address change and maintain network stability:

  • Test Configurations in a Controlled Environment: Before deploying changes to the production environment, test the new configuration in a controlled setting to identify and resolve any issues.
  • Maintain Original Engineering Copies: Having the original engineering copies of the HMI projects ensures that any necessary adjustments can be made accurately.
  • Regular Backups: Regularly back up device configurations to prevent data loss and facilitate easy recovery in case of issues.
