1. Why the Compatibility List Matters
WinCC is not a standalone application; it sits at the intersection of industrial automation (PLC communication) and IT (databases, reporting). Siemens rigorously tests specific combinations of:
- Windows OS (Build versions, features, and updates)
- SQL Server (Standard vs. Express, specific Service Packs)
- Automation hardware (S7-1200, S7-1500, S7-400)
- Office suites (for report generation and archiving)
Critical Note: WinCC 7.5 SP2 dropped support for several older OS versions. Attempting to force installation on Windows 7 or Windows Server 2008 will result in the installer blocking the setup or unpredictable behavior during archiving.
Other Integrations
- Microsoft Office (for Reporting): Office 2016, Office 2019 (32-bit)
- Adobe Reader for documentation: any recent version
- Antivirus (whitelist WinCC folders): Symantec, McAfee, Trend Micro (specific versions in Siemens’ AV list)
SQL Server – Non-negotiable
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). Windows OS (Build versions, features, and updates) SQL
During installation, the WinCC setup automatically installs a named instance: WINCC. Don’t change this unless you really know what you’re doing.
