7.5 Sp2 Compatibility List — Wincc

The significance of the WinCC 7.5 SP2 compatibility list extends far beyond a mere technical datasheet; it represents the critical bridge between legacy industrial stability and modern computing environments. In the complex world of Supervisory Control and Data Acquisition (SCADA), software compatibility is the foundation upon which operational reliability is built. For engineers and system integrators, the release of Service Pack 2 for SIMATIC WinCC 7.5 marked a pivotal moment in the lifecycle of the product, specifically regarding its alignment with the evolving Windows ecosystem.

A primary pillar of the WinCC 7.5 SP2 compatibility framework is its relationship with operating systems. While earlier iterations of the 7.5 series were anchored to older environments, WinCC 7.5 SP2 (or 8.0) is compatible with Windows 11, effectively extending the relevant lifespan of existing hardware and software investments. This compatibility also includes support for Windows Server 2022, providing a robust path for enterprises to modernize their server infrastructure without abandoning a stable SCADA platform. The strict adherence to these released combinations is non-negotiable for maintaining manufacturer support and ensuring system integrity.

Beyond the operating system, the compatibility list serves as a roadmap for integration within the broader Siemens automation portfolio. In industrial settings, WinCC rarely operates in a vacuum; it must coexist with engineering tools like the TIA Portal and SIMATIC STEP 7. The compatibility documentation ensures that communication drivers, database interfaces, and optional packages—such as WinCC/WebNavigator or WinCC/Audit—are synchronized with the core Service Pack 2 updates. This synchronization prevents the "version mismatch" errors that can cripple a facility during a staged upgrade.

Furthermore, the transition to WinCC 7.5 SP2 highlights the evolution of system architectures. While WinCC Professional is often associated with the TIA Portal ecosystem, WinCC v7.5 supports a Distributed architecture, allowing for up to 18 redundant servers. Understanding how SP2 impacts these distributed environments is essential for high-availability applications where downtime is not an option.

Ultimately, the WinCC 7.5 SP2 compatibility list is an essential risk-management tool. It allows decision-makers to plan upgrades with precision, identifying exactly which hardware needs replacement and which virtual environments are suitable for hosting. By consulting the Siemens Compatibility Tool for these specific releases, organizations can navigate the shift toward modern IT standards while preserving the proven logic and visualization of their industrial processes.

Siemens does not provide a single, static HTML page for compatibility lists anymore. Instead, they use dynamic online tools or PDF documents to detail compatibility.

Here is the compatibility breakdown for WinCC V7.5 SP2.

4. Compatibility with SIMATIC STEP 7 & TIA Portal

WinCC 7.5 SP2 can integrate with both STEP 7 Classic and TIA Portal via integrated or separate installations.

| Engineering Software | Version | Compatibility | |----------------------|---------|----------------| | TIA Portal WinCC Professional (as tag server) | V16, V17, V18 | ✅ (via S7-1500 OPC UA / HMI connection) | | STEP 7 Professional (Classic) | V5.6 or higher | ✅ (same PC, use "AS-OS Engineering") | | TIA Portal WinCC Advanced (as client) | V16–V18 | ⚠️ Limited (separate PC recommended) | | SIMATIC Logon | V1.6 SP2 | ✅ |

Note: Installing WinCC 7.5 SP2 and TIA Portal on the same engineering PC is possible but requires strict installation order (TIA first, then WinCC).

Other Software Compatibility

WinCC 7.5 SP2 is also compatible with the following software: The significance of the WinCC 7

Microsoft Office: 2013, 2016, and 2019 (32-bit and 64-bit)
Adobe Acrobat: DC and Reader DC

Upgrade and Migration Paths

If you are currently using an earlier version of WinCC, you can upgrade or migrate to WinCC 7.5 SP2. The following upgrade and migration paths are supported:

WinCC 7.4: Direct upgrade to WinCC 7.5 SP2
WinCC 7.3: Upgrade to WinCC 7.4, then to WinCC 7.5 SP2
WinCC 7.2: Upgrade to WinCC 7.3, then to WinCC 7.4, and finally to WinCC 7.5 SP2

Conclusion

In conclusion, WinCC 7.5 SP2 offers enhanced features, improved performance, and better compatibility with other Siemens products. By referring to the compatibility list provided in this article, you can plan and ensure a smooth migration or implementation of WinCC 7.5 SP2. It is essential to verify the compatibility of your hardware, software, and operating systems before upgrading or migrating to WinCC 7.5 SP2.

Recommendations

Based on the compatibility list, we recommend:

Carefully evaluating your current system configuration and planned upgrades or migrations.
Verifying compatibility of all hardware, software, and operating systems with WinCC 7.5 SP2.
Planning a smooth migration path to minimize downtime and ensure continuous operation.

By following these recommendations and referring to the WinCC 7.5 SP2 compatibility list, you can ensure a successful implementation or migration of your HMI system. Note: Installing WinCC 7

Compatible PLC & Communication

| Protocol | Compatibility | |----------|----------------| | S7-1200 / S7-1500 | ✅ Full (via S7-1500 driver) | | S7-300 / S7-400 | ✅ Full | | S5 (AS511) | ⚠️ With legacy driver pack | | Modbus TCP | ✅ (Add-on package required) | | OPC UA (Client/Server) | ✅ Built-in, DA & UA | | Profinet (softbus) | ✅ |

Licensing in VMs:

Soft dongles (ALM) are difficult to manage in dynamic VMs. Siemens recommends using a USB hardware dongle on a dedicated key server or Static license file (SLS).

Key OS Takeaways for WinCC 7.5 SP2:

No support for Windows 7 or Windows Server 2012 R2. You must upgrade your OS.
Windows 10 LTSC (Long-Term Servicing Channel) is the gold standard because it lacks feature updates that frequently break Siemens dongle drivers (ALM).
Windows 11 is not in the official compatibility list. While some users force it, Siemens technical support will reject tickets related to OS issues if you use Windows 11.

3. Database Compatibility

WinCC uses Microsoft SQL Server for archiving and licensing.

| WinCC Component | Required SQL Version | Notes | |----------------|----------------------|-------| | WinCC V7.5 SP2 (new install) | SQL Server 2017 Standard / Enterprise | Must be English collation (SQL_Latin1_General_CP1_CS_AS) | | WinCC V7.5 SP2 Upgrade from older version | Migrates SQL 2014 → SQL 2017 | Requires uninstall of old SQL | | WinCC Archiving | SQL Server 2017 | No support for Azure SQL / Express editions |

Critical: Do not install any other SQL instance on the same machine. WinCC requires its own named instance (WINCC).

3. SQL Server Compatibility for WinCC 7.5 SP2

WinCC uses Microsoft SQL Server for process value archiving, alarm logging, and user administration. WinCC 7.5 SP2 still relies on a dedicated MS SQL instance (not the TIA Portal integrated one).

3. Communication Drivers (SIMATIC NET)

WinCC V7.5 SP2 typically requires specific versions of SIMATIC NET for connecting to S7-300/400/1200/1500 PLCs.

SIMATIC NET V15: Supported.
SIMATIC NET V15.1: Supported.
SIMATIC NET V16: Supported (Check for specific restrictions on legacy drivers like OPC DA).
