With the release of WinCC 7.5 SP2, users are eager to upgrade and take advantage of its enhanced features and improvements. However, before making the leap, it's crucial to ensure compatibility with existing systems, hardware, and software. In this article, we'll provide an in-depth look at the WinCC 7.5 SP2 compatibility list, helping you make an informed decision and ensuring a seamless transition.
Introduction to WinCC 7.5 SP2
WinCC 7.5 SP2 is a powerful HMI software designed for industrial automation and process control. This latest version offers a range of new features, including improved performance, enhanced security, and better integration with other Siemens products. The service pack 2 update provides bug fixes, stability improvements, and additional functionality, making it an attractive upgrade for existing users.
Why Compatibility Matters
When upgrading to WinCC 7.5 SP2, compatibility is crucial to avoid potential issues, such as:
WinCC 7.5 SP2 Compatibility List
To ensure a smooth transition to WinCC 7.5 SP2, Siemens has provided a comprehensive compatibility list. Here's an overview of the compatible hardware, software, and operating systems:
The base SP2 ISO (released in early 2020) is not the best version. You must apply updates to fix known OS compatibility bugs.
SCADA is useless without connectivity to PLCs. WinCC 7.5 SP2 requires a matching version of the communication suite.
For users looking to deploy SIMATIC WinCC V7.5 SP2, staying within the official compatibility list is critical for technical support and system stability. Siemens recommends using their dedicated Compatibility Tool to verify specific software and hardware combinations. Core Operating System Compatibility
WinCC V7.5 SP2 is primarily designed for 64-bit architectures. The most stable and common environments include:
Windows 10 Pro/Enterprise: Officially supports versions 2004 and 20H2. Windows 10 LTSC: Supports 2016 and 2019 builds.
Windows 11: Officially supported starting with version 22H2, provided Internet Explorer 11 is enabled for internal web components.
Windows Server: Compatible with 2012 R2, 2016, and 2019 (Standard and Datacenter editions). Critical Technical Requirements
To ensure your "story" of deployment is a success, keep these prerequisites in mind: When deploying Siemens SIMATIC WinCC V7
SQL Server: This version includes and requires SQL Server 2016 SP2 (64-Bit).
Microsoft Office: Supported for Office 365 Professional Plus (versions 1908 and newer) in both 32-bit and 64-bit.
Browser Note: For Windows 10 LTSC 2019, it is highly recommended to download and install Microsoft Edge (Chromium), as the default is often an older IE version.
Backward Compatibility: Be cautious when migrating projects. While SP2 backups may run on standard WinCC 7.5 systems, any modifications made to .pdl files within SP2 cannot be reverted if opened in the older version. Product Lifecycle & Support
Active Support: Siemens typically supports the current main version and the two previous versions. WinCC V7.5 SP2 is currently in its "phase-out" period as of October 2025.
End of Life: Product discontinuation and cancellation for V7.5 SP2 are currently slated for October 2027.

WinCC 7.5 SP2 Compatibility: The Ultimate Guide to Best Practices
Achieving a stable SCADA environment requires strict adherence to the SIMATIC WinCC V7.5 SP2 compatibility list. Operating outside these parameters often leads to SQL Server installation failures, runtime instability, or broken communication with PLCs. Core Operating System Support
WinCC V7.5 SP2 is designed primarily for 64-bit architectures. For a reliable setup, verify your OS version against the official WinCC Delivery Release. System Type Supported Operating Systems (64-bit only) Workstations
Windows 10 Professional & Enterprise, Windows 11 (see notes) LTSC Versions Windows 10 LTSB 2015/2016, LTSC 2019 Servers Windows Server 2012 R2, 2016, 2019
Note on Windows 11: While original V7.5 versions were not compatible, WinCC V7.5 SP2 and higher officially support Windows 11 Pro and Enterprise.
Server 2022: Official support generally begins with WinCC V7.5 SP3 or later versions like WinCC V8.0. Critical Software Requirements
Compatibility isn't just about the OS. WinCC relies on a specific ecosystem of middleware and database tools.
Microsoft SQL Server: WinCC V7.5 SP2 requires Microsoft SQL Server 2016 SP2 (64-bit). Using newer versions like SQL 2022 without an official service pack from Siemens can break project connections.
Virtualization: Siemens supports running WinCC on VMware ESXi (6.5, 6.7, 7.0) and Microsoft Hyper-V (2012 R2, 2016, 2019).
.NET Framework: Installation of the SQL Management Studio typically requires .NET Framework 3.5. Depending on your OS, you may also need versions 4.7 or 4.8. Hardware & Environment Best Practices Hardware incompatibility : Incompatible hardware can lead to
To prevent performance bottlenecks, follow the recommended hardware specifications rather than just the minimum requirements:
For official and the most up-to-date documentation on SIMATIC WinCC V7.5 SP2, Siemens recommends using their Compatibility Tool for Automation and Drive Technology. This tool allows you to check specific combinations of operating systems, SQL versions, and other SIMATIC software. Operating System Compatibility
WinCC V7.5 SP2 is officially released for the following 64-bit operating systems: Windows 10: Professional and Enterprise Windows 10 LTSC: 2015, 2016, and 2019 versions
Windows 11: Supported only starting with WinCC V7.5 SP2 (and V8.0)
Windows Server: 2012 R2, 2016, 2019, and 2022 (64-bit versions) Hardware & Software Requirements

SIMATIC WinCC V7.5 SP2 , staying within the "released" compatibility list is critical to avoid database connection failures or runtime crashes. While it was originally designed for Windows 10, service packs and updates have expanded its reach to modern environments like Windows 11. Industrial Monitor Direct Core Operating System Compatibility
WinCC V7.5 SP2 is a 64-bit application that supports the following operating systems: Windows 10 (64-bit): Professional and Enterprise editions, including LTSB 2015/2016 Windows 11 (64-bit): Officially supported as of version
, provided Internet Explorer 11 is enabled via Windows Features for internal web components. Windows Server: Standard / Datacenter (64-bit). Standard / Datacenter (64-bit). Standard / Datacenter (64-bit). Database & Software Dependencies Microsoft SQL Server: WinCC V7.5 SP2 requires SQL Server 2016 SP2 (64-bit)
Do not attempt to manually upgrade to SQL Server 2022; WinCC is only released with the specific SQL version it is delivered with. Microsoft Office: Excel Workbook Wizard for DataMonitor only supports 32-bit Office installations. Microsoft Edge is supported for WebNavigator as of Update 1.

A SCADA system that cannot talk to the PLC is just a pretty slideshow. The compatibility list dedicates significant space to SIMATIC NET and channel drivers. For WinCC 7.5 SP2, the best-in-class configuration involves ensuring that the Industrial Ethernet (IE) driver version matches the firmware of your Siemens controllers (S7-1200/1500).
Crucially, the list clarifies which versions of OPC UA are supported. WinCC 7.5 SP2 introduced enhanced OPC UA client functionality, but it requires a specific patch level. The compatibility list shows that while basic OPC DA is supported, OPC UA certificates require Windows Server 2019’s specific security protocols. Ignoring this leads to "Certificate Untrusted" errors that halt data flow.
Furthermore, for users connecting to third-party PLCs (Rockwell, Modbus, etc.), the list identifies which Communications Channel DLLs are validated. A "best" practice is to avoid using generic TCP/IP sockets; instead, use the certified SIMATIC OPC Server listed in the compatibility matrix.
