License Key Not Available Wincc Logging For Runtime Advanced Work _hot_ Review

To help you quickly resolve the "License Key Not Available" error for WinCC Logging on Runtime Advanced, here is a concise action plan:

WinCC Runtime Advanced 在启动时，会默认启动一些后台服务，包括归档服务（Archive Service）。即使项目本身没有配置归档，但某些版本的运行时，系统自身的服务可能就已经触发了对 Logging 许可证的依赖。

To determine your exact issue, you must evaluate the project environment using the Siemens Automation License Manager (ALM) . 1. Check for Missing vs. Defective Keys

Click on the local drive in ALM and ensure the logging license appears in the list with a green checkmark status. Step 4: Configure and Restart the Runtime To help you quickly resolve the "License Key

If the license exists but the error persists, use these steps to fix the communication between WinCC and the License Manager.

Open the ALM and check the view to see exactly which key is required.

你的项目可能最初是为 Comfort Panel（TP700 / TP1200）编写的，后来被逐步“升级”成 Runtime Advanced 项目。在 Panel 上运行时，Logging 被包含在系统中，不会报错；但一旦移植到 Runtime Advanced 平台，这些 Logging 设定仍然存在于后台，并触发了许可校验。 Defective Keys Click on the local drive in

If you purchased the license but it is still sitting on a USB flash drive or your engineering PC, you must transfer it to the local PC executing the runtime.

Navigate to . Look for any configured data logs storing process tag records into .csv , .txt , or database files. If you are trending variables historically over time on a Trend View object, an underlying Data Log must exist. 2. Alarm Logs

Your application records and stores system alarms historically via Historical data > Alarm logs . or database files.

First, verify if your project actually needs the logging license. Sometimes, logging is enabled accidentally or left over from a template. Open your project in . Navigate to your HMI device in the project tree. Open Historical Data . Check both the Data logs and Alarm logs tabs.

(Note: Physical SIMATIC Comfort Panels or Mobile Panels do not require separate logging or recipe licenses for historical data tasks; this constraint strictly applies to PC-based Runtime setups). Resolution Pathways

If you see the license but it's damaged, you'll likely need to contact Siemens support for repair or follow the process to move a fresh copy to the machine.

Is this happening on an or a Production Runtime PC ?
