Am I in the correct thinking that the two options for the main database on TIA setup says MS SQL & SQL Lite, these options are either SQL Lite that comes with the build or MS SQL that comes as the extra license, that has to be downloaded / supplied from siemens? I've just tried to install MS SQL express and there are loads of reference on how to connect to it but I'm assuming this is as an external database and not the main database for WinCC Unified?

Appreciate your help

Hello antsals82,

The SQL database in both versions is supplied with the purchase of Unified: Installation of WinCC Runtime Unified
