Here’s a concise, blog-style post about WinCC 7.5 SP2 compatibility. You can copy this directly to your site or use it as a template.
WinCC 7.5 SP2 requires Microsoft SQL Server 2017 Standard / Enterprise. It will not work with SQL 2019 or 2022 unless you apply specific patches (rare).
During installation, the WinCC setup automatically installs a named instance: WINCC. Don’t change this unless you really know what you’re doing.
SIMATIC Logon 1.6 SP3 is fully compatible. Do not use v1.7 (for TIA Portal V17) – it will break WinCC user administration.
WinCC 7.5 SP2 installs a bundled SQL instance named
WINCC. Do not manually upgrade SQL separately.
