TIA Portal V13 SP1 Update 4 is an older engineering suite (STEP 7, WinCC, StartDrive) released for legacy Siemens automation hardware. By 2021 it remains useful only in specific scenarios: maintaining existing V13 projects, working with older PLCs/HMIs not supported by newer TIA versions, or when project migration is costly/risky.
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:
V13 SP1 Update 4 → Convert to V14 SP1 first → Then to V15.1 → Then to V17. (Direct conversion to V17 often fails for large projects.)
| Aspect | V13 SP1 Update 4 | V15/V16/V17 (2021) | |--------|------------------|----------------------| | | No (S7-1500V, S7-200 SMART not supported) | Yes | | Performance in large projects | Good | Much better (multi-processing) | | Learning curve | Low (classic interface) | Steeper (ribbon UI, new libraries) | | Security features | Basic (no certificate manager) | Advanced (TLS 1.2, OPC UA security) | | Backward compatibility | Opens old projects directly | Requires migration (often problematic) |
The Windows 10 compatibility question deserves deeper exploration, as it became increasingly relevant throughout 2021. siemens tia portal v13 sp1 update 4 better 2021
: Certain older S7-300 or early S7-1200 CPUs have firmware limitations that are most stably managed within the V13 environment. Stability over Innovation
: 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.
While modern industrial setups default to newer releases like V17, V18, or V20, thousands of global production lines still run reliably on and S7-1500 controllers configured nearly a decade ago.

Industrial automation prioritizing stability over novelty often dictates staying on specific software baselines. Upgrading a stable, validated production line to a newer TIA Portal version introduces risks of firmware mismatches and unexpected code compilation behaviors.
. It serves as the definitive bridge between the "old world" of early TIA Portal and the "new world" of modern automation, ensuring that a decade's worth of engineering work remains accessible and upgradeable. Do you need help downloading a specific service pack or a legacy project to a newer version?
In the fast-paced world of industrial automation, newer is not always better. By 2021, Siemens had already launched TIA Portal V16 and V17, pushing the boundaries of digital twins, cloud connectivity, and advanced security. Yet, a surprising number of production engineers, system integrators, and maintenance teams clung to a specific version: .
: If you are on a modern OS, Siemens recommends moving to V13 SP2 . It is the version that introduced official Windows 10 support and is available at no extra license cost for V13 owners. The answer depends on your environment
In 2021, Siemens was actively releasing new generations of hardware. V13 SP1 Update 4 could not support:
: The update introduces improved multi-core processor usage. It consumes roughly 10% more system memory to dramatically speed up code compilation and HMI generation.
