Siemens Tia Portal V13 Sp1 Update 4 Better 2021 Upd May 2026

Here’s the direct, deep technical answer:

No. TIA Portal V13 SP1 Update 4 is not "better" for 2021 (or later). It is significantly outdated and inferior for any new project or modern hardware.

Let’s break this down by context, features, compatibility, and security.

6. Migration Nightmare

If you start a project in V13 in 2021 and later need to upgrade to V17 or V18:

  • You must migrate step by step (V13 → V14 → V15 → V16 → V17). Each step can introduce errors.
  • Some hardware might become unsupported during migration.
  • HMI screens often break (fonts, objects, scripts).

2. Why “better 2021” doesn’t apply

  • v13 is end-of-life since 2018 (no security updates, no new hardware support)
  • Cannot open projects from TIA v14+ without migration
  • Many modern CPUs, drives, HMIs are not supported
  • 2021-era TIA versions (v16/v17) have:
    • Improved performance
    • Multi-user engineering
    • Cloud connectivity
    • Latest security patches

A. Rock-Solid Stability on Old Hardware

Many factories run S7-1200 controllers with firmware V4.0–V4.2, or S7-300/400 series (still supported in V13). Later TIA versions (V14+) dropped support for older firmware or required costly hardware migrations. Update 4 offered: siemens tia portal v13 sp1 update 4 better 2021

  • No unexpected downtime due to version mismatches.
  • Proven performance on legacy Profibus and older Profinet devices.
  • Full compatibility with WinCC Flexible-based panels migrated to TIA.

So when is V13 SP1 U4 actually "better"?

Only in very specific legacy scenarios:

  1. You have a machine with S7-1500 firmware V2.0 or S7-1200 V4.1 and no ability to upgrade the PLC.
  2. Your customer explicitly requires V13 for global consistency across 50+ old machines.
  3. You are maintaining a 5+ year old plant with no budget or time for migration.
  4. You have an old Windows 7 engineering laptop that must stay untouched.

Outside these cases – never.

2. Hardware Support in 2021

The biggest hurdle for using V13 in 2021 was hardware compatibility.

  • The New G2 CPUs: By 2021, Siemens was heavily pushing the "G2" (Second Generation) S7-1200 and S7-1500 CPUs (e.g., CPU 1511C-1 PN G2). Crucial Note: These newer CPUs generally require TIA Portal V16 or higher. TIA V13 SP1 Update 4 cannot configure these new hardware revisions.
  • Firmware Updates: While V13 SP1 Update 4 supports upscaling firmware to a degree, it hits a ceiling with the latest hardware innovations (like integrated OCR on HMI or advanced motion control features introduced in newer firmware).
  • Legacy Support: Conversely, if you are maintaining older S7-300 or S7-400 systems integrated into TIA, V13 offers excellent support that feels snappier than the heavier, newer portals on older laptops.

Introduction

In the fast-paced world of industrial automation, software versions move quickly. By 2021, Siemens had already released TIA Portal V15, V16, and the highly anticipated V17. However, a significant portion of the user base remained anchored to the older, battle-tested TIA Portal V13 SP1 Update 4. Here’s the direct, deep technical answer: No

For many system integrators and maintenance engineers, "newer" doesn't always mean "better" for existing projects. This post explores why V13 SP1 Update 4 remained a relevant "better" choice for specific scenarios in 2021, analyzing its stability, compatibility, and legacy status.

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. You must migrate step by step (V13 →

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:
