While WinCC Runtime Advanced handles standard HMI tasks, historical data logging is a separate, billable option that requires its own dedicated license key. Why This Error Happens

: SIMATIC WinCC Runtime Advanced (e.g., 128, 512, or 2048 PowerTags).

In some cases, the project might have used a logging or recipe function only briefly, leaving a "footprint" that triggers a license check. You can create a new project and copy your HMI tags and screens into it, avoiding the logging configuration to see if the message disappears. Be thorough in checking "Project Settings" for any leftover options-related configurations.

Check the column to ensure it says "Unlimited" and verify that the version matches or exceeds your installed WinCC Runtime Advanced version. Step 2: Acquire and Transfer the Correct License Key

Once acquired, open ALM, connect your source drive (or log into your OSD account via ALM), and drag-and-drop the WinCC Logging for Runtime Advanced license key onto your local C: drive. Step 3: Restart the Automation License Manager Service

The error message is a frequent point of confusion for automation engineers working within the Siemens TIA Portal environment. This system alert triggers during runtime activation or simulation when a project is configured to historically log process values or alarms, but lacks the specific localized option license required to execute that action. Root Cause of the License Alert

in TIA Portal, remove all Tag and Alarm logs, and disable "Good Manufacturing Practice" before downloading to the PC again. for the logging licenses or how to repair a license marked as defective?

Would you like help identifying the exact license part number for your TIA version?

If you have upgraded your TIA Portal version (e.g., from V17 to V18), your old logging license will not work unless you purchase a or Upgrade license key. Siemens licenses are generally backward compatible but not forward compatible. Common Workarounds Disable Logging

: A historical trend, alarm log, or process data archive was enabled in the TIA Portal engineering project by mistake, triggering a mandatory system license check.

When developing HMI/SCADA applications using Siemens TIA Portal, particularly with , engineers often encounter the frustrating error message: "License key not available! WinCC Logging for Runtime Advanced."

To resolve this, you need to ensure you have the correct software keys installed via the .

This pop-up message usually indicates one of three common issues:
