This error occurs when attempting to use WinCC Logging (data logging and archiving) within a Runtime Advanced project (typically part of TIA Portal). The system reports that the required license for the “WinCC Logging for Runtime Advanced link” is missing or cannot be accessed.
Follow this systematic approach to resolve the error.
To fix the error, you must first understand the architecture.
The Root Cause: The error means the licensing manager (ALM – Automation License Manager or TIA Portal licensing service) has scanned your computer and found:
If you want, tell me the exact error text, WinCC version, and whether you use a dongle or network license and I’ll give targeted next steps.
Troubleshooting: "License Key Not Available" for WinCC Logging This error occurs when attempting to use WinCC
If you are seeing the "License key not available! WinCC Logging for Runtime Advanced" error, it is typically because WinCC Runtime Advanced handles logging differently than Comfort or Basic panels. While panels often include logging capabilities in their hardware price, PC-based Runtime Advanced requires a dedicated separate license for any data or alarm logging. 1. Identify the Cause The most common reasons for this error include:
Missing Option License: You may have the basic "WinCC Runtime Advanced" license (which covers PowerTags), but you lack the specific "WinCC Logging for Runtime Advanced" option license.
Defective Licenses: If the PC or IPC was shut down improperly (e.g., power failure), a correctly installed license can be marked as "defective" in the Automation License Manager (ALM).
Simulation Mode: Running a simulation on an engineering PC that is connected to a live PLC also triggers a check for the Logging license. 2. Required Licenses
To run a project with logging on a PC, you generally need two distinct keys: The Root Cause: The error means the licensing
Base License: SIMATIC WinCC Runtime Advanced (e.g., 128, 512, or 2048 PowerTags).
Option License: SIMATIC WinCC Logging for Runtime Advanced (Article No: 6AV2107-0GA00-0BB0). 3. Step-by-Step Solutions Recommended Action New Setup
Verify you have purchased and transferred the Logging license key via Automation License Manager (ALM). Existing License Showing Error
Open ALM, right-click your license, and select "Check." If it shows as "defective," contact Siemens Technical Support to restore it. Unintended Logging
If you don't need logging, check your project for configured Data Logs or Alarm Logs and delete them to remove the license requirement. SmartServer Popup If you want, tell me the exact error
Sometimes a similar popup appears for SmartServer even if not used. Disable the "CoRTSmartServer" service in Windows Service Manager if not needed. 4. Important Considerations
Clean Shutdowns: To prevent license corruption, always exit the WinCC Runtime cleanly before shutting down the OS. Using a UPS is highly recommended for IPCs in the field.
ALM Version: Ensure you are using the latest version of the Automation License Manager, as older versions sometimes have compatibility issues with Windows 10/11.
Warning: These are strictly for testing or short-term validation. Do not use in a live production environment.
