Blog post — Is Siemens TIA Portal V13 SP1 Update 4 still useful in 2021?

1. Executive Summary

This report evaluates the viability, risks, and technical implications of using Siemens TIA Portal V13 SP1 Update 4 during the calendar year 2021. While this specific software version was considered mature and stable, it had reached the end of its mainstream product lifecycle by 2021.

The conclusion of this report is that while V13 SP1 Update 4 was functional in 2021, it was not "better" than contemporary versions (V15.1, V16, or V17) for new projects. Its use in 2021 was primarily restricted to legacy system maintenance due to significant security risks, hardware compatibility limitations, and the absence of modern engineering features.

Quick compatibility checklist

Practical Verdict: Should you use Update 4 in 2021+?

| Scenario | Recommendation | | :--- | :--- | | Maintaining a live factory line installed in 2016-2018 | YES. Do not upgrade the software. V13 SP1 Update 4 is the most stable build for your existing hardware. | | Designing a new machine from scratch in 2021 | NO. Use TIA Portal V17 or V18. V13 lacks modern security and performance features. | | Recovering an archived project from an OEM | YES. If the OEM sent you a V13 SP1 project, using Update 4 is essential to avoid conversion errors. | | Using new HMIs (WinCC Unified) | NO. Unified requires V16+. |

1. Core Identity: V13 is from 2014–2015

Using V13 SP1 U4 in 2021 is like running Windows 7 in 2021 – possible, but unsupported for new hardware and missing critical improvements.

Conclusion: The Legacy Anchor

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. siemens tia portal v13 sp1 update 4 better 2021

Looking for the official Siemens Download? As of 2021, Siemens moved V13 to the "Legacy Software" section of the Global Download Server. A valid Service & Support contract (SSC) is required to access it.

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. Blog post — Is Siemens TIA Portal V13

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
