I want to log tags to SQL Server on another machine. Do you usually use JavaScript to write data into the SQL database, or do you use logging tags? I want to use logging tags to store data into a database on another computer that has SQL Server installed, but I cannot find where to configure the connection path to my SQL Server.

However, Siemens offers a central data storage add-on for SIMATIC WinCC Unified called the SIMATIC WinCC Unified Data Hub. Using that would be much easier. Kind regards Stefan
