Hello,

With the standard Comfort Panels, it was possible to log data directly in CSV or TXT format, transfer the files to a PC, and open them immediately in Excel.

In the new Unified Comfort Panels, I noticed that the data logging architecture and file handling are quite different. The logs are not saved directly as CSV or TXT, and direct export of logs in Excel (.xls / .xlsx) format is also not supported. From what I understand, the logs are typically stored in internal databases.

Could anyone clarify:

1. What is the recommended way to export log data from Unified Comfort Panels for direct use in Excel?
2. Is there a method to automatically generate CSV files instead of dealing with database extraction?
3. Are there any Siemens-provided tools/utilities for converting the internal database logs into Excel-readable formats?

Thanks in advance for any guidance.

Hello Murof,

Thanks for your explanation. I understand that the internal format is SQLite. You mentioned exporting via the Trend Control export button or by using JavaScript.

Could you clarify if there are any options to directly view or extract the log data as CSV on the HMI itself (without needing to transfer the database to a PC first)?

For example:

• Can the Trend Control export button on the Unified Comfort HMI be configured to save/export CSV files directly onto a USB stick or network folder?

• Is there a built-in function block, script, or panel control that allows the operator to trigger a CSV export on demand from the HMI runtime?

• Or does this always require custom JavaScript programming?

This would be very helpful for cases where operators want quick access to CSV logs without PC intervention.

Thanks again for your support!
