1. Peak Maturity for the V13 Ecosystem Software is like wine; some vintages peak late. By Update 4, Siemens had stopped developing V13. This meant no new bugs were being introduced. For a frozen production line, this is ideal. The update was the most debugged version of the V13 kernel available.
2. Hardware Support Sweet Spot Update 4 supports the S7-1200 (FW 4.1), S7-1500 (FW 1.8), and WinCC Comfort panels (FW 13). In 2021, many factories still had spare parts stocked for these exact firmware versions. Upgrading to V17 would have required flashing all your hardware to new firmware—risky in a live plant. Update 4 allowed you to keep hardware frozen.
3. The "Last" Version for Old Operating Systems Many 2021 corporate IT policies still prohibited Windows 10 20H2 or 21H1. V13 SP1 Update 4 runs perfectly on Windows 7 SP1 and Windows 8.1, whereas newer TIA versions (V15+) drop support for these. If your plant PC was stuck on Windows 7 in 2021, Update 4 was objectively better than any newer TIA version.
While 2021 belonged to TIA Portal V16 and V17, TIA Portal V13 SP1 Update 4 remained a critical tool for the legacy engineer. It represented the moment Siemens stabilized the TIA transition, and for many, it remained the "better" choice purely for its speed and reliability on older hardware. Just remember: for new projects, the future had already arrived.

By 2021, Siemens TIA Portal V13 SP1 Update 4 reached a complex status: while it remained a cornerstone for maintaining older legacy systems, it was largely superseded by V13 SP2 and newer versions like V17 for modern workflows. The Legacy Bridge: Why V13 SP1 Remained Relevant
In the industrial automation landscape of 2021, V13 SP1 served as a critical "bridge" version.
Stability for Legacy Systems: Users often cited V13 SP1 as one of the most stable versions for older S7-1200 (FW 4.0-4.2) and S7-1500 hardware.
Update 4 Improvements: This specific update addressed major stability issues, such as crashes when a PC woke from sleep while connected to a PLC. It also improved the STEP 7 Safety license compatibility and enabled automatic support for previously "unsupported" F-blocks.
Mandatory Migration Step: Projects created in versions before V13 must first be upgraded to V13 SP1 before they can be migrated to later versions like V15.1 or V17. Challenges and Limitations in 2021
Despite its reliability, V13 SP1 faced significant hurdles by 2021: (USER FEEDBACK) TIA Portal V13 SP1 Update 4 - SiePortal
Siemens TIA Portal V13 SP1 Update 4 was unequivocally "better" than any prior version of V13. In 2021, it represented the final, most stable, and most capable version of the V13 generation.
However, "better" is a dangerous word. It is not better than V17 for a greenfield project. It is not better for cybersecurity. But for a plant manager staring at a 10-year-old PLC that cannot be shut down for a firmware upgrade, Update 4 is the gold standard.
Final Takeaway: Keep a copy of the "Siemens_TIA_Portal_V13_SP1_Upd4.exe" installer on a secure network drive. As Windows evolves, this installer becomes a valuable digital artifact for maintaining legacy industrial assets. Do not install it on a Windows 11 host. Do use it in a VM. And respect the fact that in 2021, Update 4 kept the lights on in thousands of factories that couldn't afford to stop.

Are you planning a firmware upgrade for your hardware along with this software update, or just looking to stabilize your current engineering environment? Update for TIA Portal V13 SP1 - SiePortal - Siemens
By 2021, Siemens TIA Portal v13 SP1 Update 4 was considered a legacy version. While it remains one of the most stable builds for older hardware, its lack of modern OS support and missing features for newer PLCs led Siemens to recommend v13 SP2 or higher for 2021-era systems. Key Status in 2021
Support Status: By 2021, TIA Portal v13 SP1 was largely out of official support. Users were encouraged to move to v13 SP2 to maintain compatibility with Windows 10 security updates.
Performance Improvements: Update 4 specifically improved system responsiveness and stability compared to earlier v13 builds. It addressed issues like session crashes when a PC woke from sleep mode while linked to a PLC. Compatibility:
OS: v13 SP1 is officially compatible with Windows 7. Running it on Windows 10 often requires v13 SP2 or the use of a virtual machine.
Hardware: Projects using this version cannot support newer PLC firmware (e.g., S7-1200 FW 4.2+), which requires at least TIA Portal v14.
Legacy Value: It remains a "gold standard" for stability when maintaining older SIMATIC S7-1200 and S7-1500 systems that do not require the overhead of newer versions like v17. Technical Highlights of Update 4
Siemens TIA Portal V13 SP1 Update 4 remains a surprisingly relevant topic in 2021, even with the availability of much newer versions like V17. For many automation engineers, "newer" doesn't always mean "better," especially when dealing with legacy hardware and established production lines. Why Stick with TIA Portal V13 SP1 in 2021?
The primary reason engineers still search for V13 SP1 Update 4 is hardware compatibility. Many older S7-1200 and S7-1500 CPU firmware versions are natively supported in V13 without the need for complex migrations. If you are maintaining a plant commissioned between 2013 and 2015, V13 SP1 is often the "native language" of those machines.
Stability: Update 4 was one of the final refinements for V13, fixing critical bugs and communication errors.
System Requirements: V13 runs significantly faster on older laptop hardware compared to the resource-heavy V16 or V17.
Safety Integrated: This version provided a stable platform for F-CPU programming that many safety signatures are still tied to. Key Improvements in Update 4
Update 4 wasn't just a minor patch; it addressed specific performance bottlenecks that plagued the original SP1 release.
Compiler Optimization: Faster generation of block code for S7-1500 controllers.
HMI Stability: Improved simulation reliability for Comfort Panels.
Openness Enhancements: Better API support for those using automated workflow scripts.
Windows 10 Support: While V13 was originally a Windows 7 era tool, SP1 Update 4 stabilized its performance on early Windows 10 builds. The "Better in 2021" Argument
Is it actually "better" in 2021? The answer depends on your environment. In a modern greenfield project, the answer is no—you should use the latest version to leverage features like View-of-Things or advanced Motion Control. However, V13 SP1 Update 4 is "better" for:
Maintenance: Avoiding the risk of "upgrading" a working project and breaking library dependencies. Siemens TIA Portal V13 SP1 Update 4 was
Education: Learning the core logic of TIA Portal without needing a high-end workstation.
Licensing: Users with older floating licenses can often run V13 without the recurring costs or upgrade fees associated with newer versions. Migration Path and Compatibility
If you are using V13 SP1 Update 4 today, you are in a perfect position for future upgrades. This version acts as the "bridge." You cannot migrate a V11 or V12 project directly to V17; you almost always have to step through V13 SP1 first.
💡 Pro Tip: Always keep a virtual machine (VM) with V13 SP1 Update 4 ready. It is the gold standard for opening older Siemens projects and prepping them for the modern era. Conclusion
While Siemens pushes the industry toward V17 and beyond, TIA Portal V13 SP1 Update 4 remains a "workhorse" in 2021. It represents a peak of stability for the mid-2010s hardware generation. For engineers managing existing lifecycles, it isn't just an old version—it’s a necessary tool for reliable automation.

Which of these would be most helpful for your current project?
I notice you're asking about Siemens TIA Portal v13 SP1 Update 4 in relation to "better 2021."
To be clear: TIA Portal v13 SP1 Update 4 was released around 2015–2016, not 2021. It is not compatible with Windows 10/11 versions released after ~2017 without workarounds, and it cannot directly open projects from TIA Portal v14 or later.
If you're trying to decide between v13 SP1 Update 4 and a 2021-era version, the 2021 versions would be TIA Portal v16 (2020) or v17 (2021) — which are far better for modern hardware, security, and features.
However, if you specifically need v13 SP1 Update 4 (e.g., to support old hardware like S7-1200 v4.0 or WinCC Comfort panels), here’s a practical guide:
| Year | Best TIA Version | Why | |------|----------------|------| | 2021 | V16 or V17 | Stable, widely used, supports all hardware up to 2022 | | 2023–2024 | V18 | Modern features, better cloud/OPC UA | | 2025 | V19 | Latest as of now |
