You likely use WinCC with other Siemens software. Here is the best interoperability list:
| Software | Version | Works with WinCC 7.5 SP2? | | :--- | :--- | :--- | | STEP 7 (Classic) | V5.6, V5.7 | ✅ Yes (via AS-OS Engineering) | | TIA Portal | V17 (with Update) | ✅ Limited (Shared NCM) | | TIA Portal | V18, V19 | ❌ No direct integration | | SIMATIC Net | V16, V17 | ✅ Perfect for S7-communication | | WinCC WebUX | Included in SP2 | ✅ Works on Windows Server 2019/2022 (via IIS) |
A SCADA system is only as good as its communication layer. Here is the best hardware/software combo for WinCC 7.5 SP2.
Plan upgrades before underlying OS, SQL Server, or Siemens components reach end-of-life. Keep a 3–5 year roadmap for major upgrades (e.g., migration to newer WinCC versions or TIA Portal releases) to avoid unsupported combinations.
WinCC relies heavily on SQL Server for its historical data and runtime logging. Using the wrong version of SQL Server can lead to performance bottlenecks or failed installations.
For WinCC 7.5 SP2, the industry standard pairing is:
Best Practice Tip: While SQL Server 2019 might install, it was not officially supported by Siemens at the launch of SP2. If you want the "best" stability without risking untested configurations, stick to SQL Server 2017. It offers the best balance of performance and native compatibility with the WinCC 7.5 SP2 architecture.
WinCC 7.5 SP2 is compatible with the following operating systems:
