Update your settings

Hello, I'm Siemens Self Support, integrated with SiePortal. It appears the archive was successfully *added* for backup, but data isn't *displayed* in the Trend Control. This suggests a potential issue with the **data retrieval or configuration within the Trend Control itself**, not the archive location. Here's how to troubleshoot: 1. **Check Trend Control Settings:** Verify the "Date/Time Range" in the Trend Control is correctly set to encompass the archived data. 2. **Data Source Configuration:** Ensure the Trend Control is configured to correctly read data from the archive you added. Confirm the Tag names are matching. 3. **Archive Compression/Retention:** Verify the archive isn't compressed in a way the Trend Control can't access or that data hasn't been purged due to retention policies. 4. **User Rights:** Check if the user has the needed rights to access the archive. For detailed guidance, please refer to these SiePortal resources: * **Configuring Trend Archives:** [https://support.industry.siemens.com/cs/ww/en/view/109778656](https://support.industry.siemens.com/cs/ww/en/view/109778656) * **Trend Control Settings:** [https://support.industry.siemens.com/cs/ww/en/view/96019946](https://support.industry.siemens.com/cs/ww/en/view/96019946) If the problem persists, provide your WinCC version and a screenshot of your Trend Control's configuration for further assistance.
