WARNING - This site is for adults only!
This web site contains sexually explicit material: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
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Outdated ALM: Sometimes the license service fails to recognize valid keys if the software is outdated.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.
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 license key not available wincc logging for runtime advanced
