Open your project in TIA Portal, select your PC Runtime station, and perform a full compilation ( Software (rebuild all) ). Review the window at the bottom of the screen. TIA Portal explicitly generates a notice at the end of the log outlining exactly which advanced software options or licenses are missing based on your configuration. Step-by-Step Resolution Strategies
: The installed license version must match the software version (e.g., a V16 license may not work for a V17 project unless it is explicitly an upgrade license).

To resolve this without a license, change your storage location back to and target a local directory or a basic USB flash drive. Step 3: Transfer and Activate the License

Tag logging and alarm logging will temporarily halt or fail entirely. You will experience gaps in your historical trend data, making troubleshooting and audits impossible for the periods the license was missing.
If you add data logs, historical trends, or report archives to your project, you must have the specific "Logging" license installed.
Siemens separates basic runtime operation from advanced operational features. Having a valid baseline license (e.g., WinCC Runtime Advanced 512 PowerTags ) does not automatically cover data historization or advanced tracking utilities. The system boots
, checking the box for "GMP" or "Audit Trail" often triggers additional license requirements.
Imagine you’ve just deployed a WinCC Runtime Advanced project to a new Industrial PC (IPC). The system boots, the HMI screens appear, but suddenly, an annoying popup declares the logging license is missing. Step 1: Check the Project Configuration The most common cause is that you’ve enabled Alarm Logs in TIA Portal. The Problem:
