The Siemens Prodiag option for Comfort and Mobile Panels offers powerful diagnostic capabilities for automation systems. However, users occasionally encounter licensing problems that can trigger error messages even when ProDiag functionalities aren’t actively used in the project. This article explores common causes and solutions for Siemens Comfort Panel ProDiag license errors.
Understanding ProDiag Licensing
ProDiag requires a valid license to operate. This license is typically installed on the HMI device. Even if ProDiag objects aren’t explicitly used in your project, specific configurations or settings might trigger a license check. If the license is missing or invalid, an error message will appear.
Common Causes of ProDiag License Errors
Several factors can contribute to ProDiag licensing issues on Siemens Comfort Panels:
- Unintentional ProDiag Feature Activation: While you may not have intentionally incorporated ProDiag objects, certain settings, such as alarm criteria analysis or specific runtime configurations, might implicitly require the license. Hidden or forgotten objects within the project can also cause the issue.
- Project Corruption: Sometimes, project files can become corrupted, leading to unexpected behavior and license errors.
- Outdated Firmware or Software: Compatibility issues between the HMI firmware, TIA Portal version, and the ProDiag license can trigger errors.
Resolving ProDiag License Problems
If you’re encountering a ProDiag license error on your Siemens Comfort Panel, consider these troubleshooting steps:
- Verify Project Settings: Carefully review your project for any settings related to alarm analysis, logging, diagnostics, or GMP (Good Manufacturing Practice) configurations. Disabling unused features may resolve the issue. Look for features like “Graph Overview” or “ProDiag Overview” in your screens and remove them if unnecessary. Also, check for “PLC View” code.
- Inspect for Hidden Objects: Thoroughly examine all layers and elements of your HMI project, including hidden objects, for any unintended ProDiag functionality.
- Rebuild the Project: Recompiling the project can sometimes resolve underlying inconsistencies. Consider deleting the contents of the “IM” folder within your project directory before rebuilding. Saving the project under a new name can also be beneficial.
- Perform a Factory Reset: Resetting the HMI to factory defaults can eliminate any configuration issues causing the error. Remember to back up your project before performing a reset.
- Update Firmware and Software: Ensure your HMI firmware and TIA Portal software are up to date. Compatibility issues are often addressed through software updates.
- Check License Key: Confirm the ProDiag license key is correctly installed on the HMI device. If the key is missing or invalid, contact Siemens support to obtain a valid license.
Conclusion
ProDiag license errors on Siemens Comfort Panels can be frustrating, especially when ProDiag features are seemingly unused. By systematically investigating project settings, hidden objects, and ensuring software compatibility, you can often pinpoint the root cause and resolve the problem. If the issue persists, consult Siemens support for further assistance. Addressing these license issues promptly ensures smooth operation and optimal performance of your automation system.
