License Key Not Available Wincc Logging For Runtime Advanced «iPad»

Temporarily use a trial license from SIEMENS License Manager → Request Trial License to isolate hardware/ALM issues.

The "License key not available for WinCC Logging for Runtime Advanced" error is a frustrating but solvable problem. It rarely means your license is permanently lost. In 80% of cases, the solution is one of three actions:

By understanding how Siemens’ Power Tag and logging licenses interact, you can quickly diagnose the issue, implement a fix, and get back to monitoring your process without data gaps. Always remember: in the world of industrial automation, a missing license is always a human error in planning or installation—rarely a technical fault of the software itself.

The error message "License key not available! WinCC Logging for Runtime Advanced" typically occurs because SIMATIC WinCC Runtime Advanced requires an additional, separate license for any archiving or logging functions (tags, alarms, or recipes). Unlike Siemens Comfort Panels, which include logging functionality, the PC-based Runtime Advanced version requires the WinCC Logging for Runtime Advanced option to be purchased and activated independently of the base PowerTags license. Common Root Causes & Solutions license key not available wincc logging for runtime advanced

Missing Optional License: Even if you have a valid "WinCC Runtime Advanced [X] PowerTags" license, you must also have a WinCC Logging for Runtime Advanced license key (e.g., MLFB: 6AV2107-0GA00-0BB0) if your project contains a "Data Log" or "Alarm Log".

Defective License Keys: If the license is installed but showing as unavailable, it may be "defective." This often happens if the Industrial PC (IPC) was shut down improperly (e.g., power failure) without closing the Runtime software first. Check the Automation License Manager (ALM) to see if the key is marked as "defective".

Version Mismatch: Ensure the license version matches your installed TIA Portal version. For example, a V16 Logging license will not work for a V17 Runtime unless you explicitly configure the project to use the older V16 runtime version.

Outdated ALM: Sometimes the license service fails to recognize valid keys if the software is outdated. Updating the Automation License Manager to the latest version frequently resolves "pseudo-license" errors. Temporarily use a trial license from SIEMENS License

Simulation vs. Production: This message will also appear during simulation in TIA Portal if the local engineering PC does not have the logging license. While you can ignore it for testing, the license must be present on the target IPC for production. Troubleshooting Steps

Here are some steps and considerations to help you troubleshoot or resolve the issue:

Before diving into fixes, identify which scenario fits your situation:

On the target PC (where Runtime Advanced runs): The "License key not available for WinCC Logging

If you see the license but it is grayed out or shows "Defective," skip to Step 4.

If you do not see the license at all, proceed to Step 3.

If using a USB dongle, transfer the license to the PC’s hard drive via ALM. This prevents loss from damaged dongles.

Follow these steps in order to resolve the issue.
