License Key Not Available Wincc Logging For Runtime Advanced Link

If your project was originally created for a Comfort/TP Panel and is now running on a PC:

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

If missing, you must purchase the license (Article No: 6AV2107-0GA00-0BB0 ) and transfer it to the PC. If your project was originally created for a

You will need to order the specific license. For example, the article number often resembles 6AV2107-... depending on the software version. You can opt for a physical License Key USB Flash Drive or an Online Software Delivery (OSD) download.

Check the column for all configured tags. Ensure the logging setting is turned off or set to none for tags that do not need historical tracking. You will need to order the specific license

Licenses can become corrupted. This often happens when an industrial PC (IPC) is improperly shut down. When WinCC Runtime Advanced starts, it assigns a license. If the PC loses power abruptly or the operating system is not closed correctly, these licenses are not released and can be for the next startup, triggering the "License Key Not Available" error. This is a common scenario in industrial environments with unstable power grids.

: When simulating a Comfort or Mobile Panel on your PC, the simulation behaves exactly like the real hardware and looks for the same license keys. You can opt for a physical License Key

Contact Siemens support or your Siemens distributor if:

Siemens treats data logging and alarm logging as premium add-on features. The moment you create a log file in your TIA Portal project, the runtime engine looks for a specific authorization file. If the system cannot validate the "WinCC Logging for Runtime Advanced" license, it triggers the error message. The system may allow short-term evaluation, but it will repeatedly interrupt operations with nag screens and log entries. Step 1: Verify Your Current Licenses
