Using the Siemens Compatibility Tool for SIMATIC PCS 7 Software Planning

The Siemens Compatibility Tool (Kompatibilitätstool) on the Siemens Industry Online Support (SIOS) portal is the official authoritative engine for validating software and operating system interoperability before engineering a SIMATIC PCS 7 system. It evaluates release combinations across PCS 7 versions, Microsoft Windows operating systems, SQL Server editions, STEP 7, WinCC, CFC, SIMATIC NET, and add-on packages. Using the tool prevents commissioning failures caused by unsupported service packs, virtualization platform mismatches, or incompatible driver releases.

The Purpose and Scope of the Siemens Compatibility Tool

In complex automation and control system engineering, the compatibility between host operating systems, core DCS engineering platforms, communications stacks, and database engines is strictly non-negotiable. Installing an unapproved Windows security update or service pack can silently corrupt communication drivers or halt SQL database engines.

To provide clear, manufacturer-guaranteed compatibility baselines, Siemens maintains the online Compatibility Tool for Automation and Drive Technology (Kompatibilitätstool) accessible via the Siemens Industry Online Support (SIOS) portal:
* It maintains an active, updated relational database of all Siemens industrial software releases.
* It documents validated compatibility matrices spanning SIMATIC PCS 7, SIMATIC STEP 7 Classic, TIA Portal, WinCC, Safety Integrated, and drive engineering tools.
* It details exact build numbers, hotfixes, service packs, and specific operating system updates (e.g. Windows 7 SP1 64-bit, Windows Server 2012 R2, Windows 10 Enterprise LTSB/LTSC).

Why Software Interoperability Must Be Pre-Validated in PCS 7

Unlike discrete automation where standalone software can be patched incrementally, SIMATIC PCS 7 is a tightly coupled Distributed Control System (DCS). A standard PCS 7 release (such as V8.1 SP1 or V8.2) bundles over 50 interdependent software components:
* SIMATIC Manager (STEP 7)
* Continuous Function Chart (CFC) and Sequential Function Chart (SFC)
* SIMATIC WinCC and WinCC Options (Web Navigator, DataMonitor)
* Microsoft SQL Server instance (WINCC)
* SIMATIC NET PC Software communications protocols (CP 1623 / CP 1628 drivers)
* Automation License Manager (ALM)
* SIMATIC BATCH and SIMATIC Route Control

If an IT department upgrades an Engineering Station from Windows 7 SP1 to a newer Windows build without consulting the compatibility database, the WinCC SQL Server instance or SIMATIC NET NDIS drivers may fail to load, resulting in system-wide engineering paralysis.

Key Capabilities: Product Comparison and Excel Export

The Compatibility Tool provides three indispensable engineering workflows:
1. Direct Compatibility Check: Select your main product (e.g. SIMATIC PCS 7 V8.1 SP1) and an operating system; the tool instantly returns whether the combination is certified, compatible with restrictions, or strictly incompatible.
2. Multi-Product Matrix Comparison: Select up to 10 distinct software products (e.g. PCS 7 V8.1, SIMATIC PDM V8.2, S7-PLCSIM V5.4, and Process Historian 2014) to verify that all components coexist harmoniously on a single workstation.
3. Comprehensive Export to Excel: Generates an official, documented compatibility report in Microsoft Excel format, essential for client Design Qualification (DQ) and validation audits.

Step-by-Step Procedure to Validate a System Configuration

To validate a planned plant expansion or software upgrade using the Compatibility Tool:
1. Access the Tool on SIOS:
- Open a web browser and navigate to the Siemens Industry Online Support portal (support.industry.siemens.com).
- In the search bar or quick links, open the Compatibility Tool (Entry ID 64847781).
2. Select the Main DCS Software:
- Click Select Main Product.
- Navigate to Process Control Systems -> SIMATIC PCS 7.
- Select your exact target version (e.g. SIMATIC PCS 7 V8.2).
3. Add Operating System and Add-On Packages:
- In the Operating System category, check your target platform (e.g. Microsoft Windows Server 2012 R2 Standard Edition (64-bit)).
- In the Add-On Software category, add any required options: SIMATIC PDM, SIMATIC BATCH, SIMATIC Route Control, Process Historian.
4. Evaluate Compatibility Results:
- Click Show Compatibility.
- Review status badges:
- Green Check: Officially certified and tested by Siemens.
- Yellow Triangle: Compatible with specific boundary conditions (click to read mandatory footnotes or hotfix requirements).
- Red Cross: Incompatible. Software must not be installed together.
5. Download the Official Report:
- Click Export to Excel to save the timestamped validation matrix for engineering records.

Verification

Verify that your planned software media matches the compatibility report:
1. Cross-reference the official export against your installation DVD media or software download packages.
2. Verify that service packs, hotfixes, and update collections (UC) match the exact minimum build numbers specified in the tool footnotes.
3. Check the host PC operating system build via Windows winver: Confirm the OS build matches the certified patch level.
4. Verify that Microsoft .NET Framework versions installed on the target PC match the specific prerequisites listed in the compatibility matrix.

Limitations and Operational Precautions

The Compatibility Tool reflects manufacturer testing at specific points in time; always cross-check results with the official PCS 7 Readme document delivered on the installation media.
Virtualization environments (VMware vSphere ESXi, Workstation) have specific version qualifications; verify hypervisor compatibility in addition to guest OS compatibility.
Never install untested third-party antivirus software, disk defragmenters, or endpoint security suites without verifying Siemens compatibility.

Engineer FAQ

Can I run PCS 7 V8.1 on Windows 10?

No. PCS 7 V8.1 is strictly certified for Windows 7 SP1 (64-bit) and Windows Server 2008 R2 SP1. Windows 10 support was introduced with SIMATIC PCS 7 V9.0.

What does 'Compatible with restrictions' mean in the tool results?

It signifies that the software operates reliably only if specific configuration constraints are met, such as installing a mandatory Siemens Hotfix, avoiding specific hardware adapters, or disabling certain Windows services.

Is an internet connection required to use the Compatibility Tool?

The full tool runs online via the SIOS portal, but Siemens also provides downloadable offline database packages that can be executed on air-gapped engineering stations.
