Siemens Tia Portal V13 Sp1 Update 4 Better 2021

If you are coming from V13 SP1 Update 2 or 3, Update 4 brought:

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.

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.

In 2021, Siemens was actively releasing new generations of hardware. V13 SP1 Update 4 could not support:

If you share what specific hardware (PLC/HMI model) you’re using, I can tell you whether v13 SP1 Update 4 is still viable or if upgrading to v16/v17 is the better “2021” solution.

The Enduring Value of TIA Portal V13 SP1 Update 4 in 2021 While Siemens had released multiple advanced versions of its Totally Integrated Automation (TIA) Portal by 2021, Version 13 SP1 Update 4 remained a critical asset for automation engineers. Despite being "out of support" by 2019 in favor of SP2, its reputation as one of the most stable releases of the TIA framework ensured its continued use in industrial environments. A Benchmark for Stability and Performance

Released in late 2015, V13 SP1 Update 4 was a significant leap forward in software responsiveness. Reduced Latency

: Users noted that lag times were greatly reduced compared to earlier iterations like V13.0.6, making the system feel much smoother. Enhanced Motion Control : This version introduced improved abilities for Motion Control V5 S7-1200 FW4.1 PLCs siemens tia portal v13 sp1 update 4 better 2021

, which expanded the precision of small-scale automation tasks. Improved Communication

: The communication module was revamped, solving persistent issues where TIA would crash if a PC went into sleep mode while connected to a PLC. The "Stepping Stone" for Modern Migration

By 2021, V13 SP1 became essential for its role as a "stepping stone" in migration workflows. Upgrading Legacy Projects

: Projects created in TIA V12 or V13 without SP1 cannot be opened directly in V14 or higher. They must first be compiled and saved in V13 SP1 before they can be upgraded to more modern versions like V17 or V18. License Compatibility

: A major benefit of this version is its accessibility; users could update to V13 SP1 Update 4 without additional license costs if they already owned V13. Hardware Support : It supports critical hardware like the S7-1200 FW4.1

and remains one of the last versions to efficiently support older modules that might not be compatible with newer, resource-heavy releases. Operating Challenges in 2021

Despite its benefits, using V13 SP1 Update 4 in 2021 presented technical hurdles: Windows 10 Incompatibility If you are coming from V13 SP1 Update

: Officially, V13 SP1 was not compatible with Windows 10. Most engineers moved to

to maintain compatibility with modern operating systems while keeping the same project format. End of Life

: Because it is out of support, Siemens no longer provides security updates, bug fixes, or new hardware support packs for this specific release. Siemens SiePortal

In conclusion, TIA Portal V13 SP1 Update 4 was far from obsolete in 2021. It served as a stable bedrock for existing machinery and a mandatory gateway for migrating older projects into the future of Siemens automation. Are you planning to

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. In 2021, Siemens was actively releasing new generations

Let’s address the elephant in the room. By 2021, why not just upgrade to V17?

| Aspect | V13 SP1 Update 4 | V15/V16/V17 (2021) | |--------|------------------|----------------------| | New hardware support | 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) |

Conclusion in 2021: If your hardware is frozen (no new controllers) and your project is stable, Update 4 is better for uptime. If you are building a new line, you must use V17.

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

TIA Portal V17 requires 16–32 GB RAM and a modern multicore processor. V13 SP1 Update 4 runs smoothly on:

For field service engineers maintaining old machines, this made Update 4 better because it worked on older programming devices.
