At ControlNexus, we understand the challenges faced by professionals in industrial automation when it comes to uploading and managing Siemens HMI programs. Established in 2013, we have been a leading provider of Siemens PLCsHMIs, and Inverters. This guide will walk you through the essential steps and best practices for efficiently uploading and managing Siemens HMI programs using Prosave and TIA Portal.

Step-by-Step Guide to Uploading HMI Programs


Before starting, ensure you have the following:

  • TIA Portal: Siemens’ comprehensive engineering software.
  • Prosave: A tool for backing up and restoring HMI projects.

Connect your HMI panel to your PC using either an Ethernet cable or a USB connection.

Using Prosave for Backup and Restore

  1. Open Prosave and select the appropriate HMI device from the list.
  2. Backup Process:
    • Choose the backup option in Prosave.
    • Save the backup file (.psb) on your PC.
  3. Restore Process:
    • Select the restore option in Prosave.
    • Upload the .psb file back to the HMI panel.

Note: The backup file is for restoration only and cannot be edited.

Uploading Programs via TIA Portal

  1. Open TIA Portal:
    • Create a new project or open an existing one.
  2. Configure Connection:
    • Set up the connection to your HMI panel within TIA Portal.
  3. Transfer Tool:
    • Use the transfer tool to upload the project from the HMI panel.

Important: Direct editing of the project on the HMI panel is not possible without the original project file due to memory constraints and design limitations.

Common Issues and Solutions

Issue: Direct Upload Not Possible


Directly uploading and editing an HMI program on the panel is often restricted due to memory constraints and the design of Siemens HMI systems.


  • Backup and Restore: Utilize Prosave to create backups and restore projects.
  • Original Project File: Always keep the original project file for editing purposes.

Issue: Error Messages in WinCC Flexible

Common Errors

  • Incompatibility with certain HMI models.
  • Connection issues during the upload process.

Troubleshooting Steps

  • Ensure your software versions are up-to-date.
  • Verify the connection settings in both TIA Portal and Prosave.
  • Consult Siemens’ support forums for specific error messages and solutions.

Backtransfer Options


Backtransfer allows you to retrieve a project from an HMI panel that can be edited.

Steps to Use Backtransfer

  1. Check Compatibility: Ensure your HMI panel supports backtransfer.
  2. Execute Backtransfer: Follow the specific steps in TIA Portal to retrieve the editable project.

Expert Tips

  1. Regular Backups: Regularly back up your HMI projects using Prosave to avoid data loss.
  2. Software Updates: Keep your TIA Portal and Prosave software updated to ensure compatibility and access to the latest features.
  3. Documentation: Maintain detailed documentation of your HMI projects, including configurations and any changes made.


Managing Siemens’s HMI programs efficiently is crucial for the seamless operation of industrial automation systems. By following the steps outlined above and leveraging the tools provided by Siemens, you can ensure that your HMI programs are backed up, restored, and updated effectively.
