When Windows 7 began phasing out and Windows 10 became the industry standard, many older software packages were left behind. TIA Portal V13 SP1 Update 4 was a critical bridge for many companies.
While earlier versions of V13 struggled on Windows 10, Update 4 was designed to be compatible with the new operating system. This allowed factories to upgrade their engineering laptops without being forced to upgrade their entire PLC software suite immediately. For many, this compatibility is what made V13 SP1 Update 4 "better" than its predecessors.
One of the most significant pain points in early TIA Portal versions was the integration of drive technology. Engineers often had to switch between the TIA Portal and the standalone "STARTER" software to configure SINAMICS drives.
V13 SP1 Update 4 offered a much more robust integration of the STARTER toolset directly within the TIA Portal interface. This allowed for better parameterization of SINAMICS G120 and S120 drives. The "better" experience here is defined by workflow—being able to handle PLC logic and Drive configuration in a single window without crashing the software was a massive productivity booster.
Here’s a blog post highlighting why TIA Portal V13 SP1 Update 4 is a significant jump over the base V13 release.
Is TIA Portal V13 SP1 Update 4 Actually Better? (Short Answer: Yes)
If you’re still wrestling with the base version of Siemens TIA Portal V13, you’ve likely hit the "lag wall" more than once. While the jump to Service Pack 1 (SP1) was the big "feature" update, Update 4 is where the software actually becomes reliable for daily engineering.
Here is why making the move to V13 SP1 Update 4 is worth the (admittedly slow) installation process. 1. The End of the "Sleep Mode" Crash
In earlier versions, if your PC went into sleep mode while connected to a PLC, TIA Portal would often crash upon waking. This sometimes left the CPU unresponsive, forcing a physical power cycle. Update 4 finally stabilized the communication module, making the software much more resilient to power management glitches. 2. Noticeable "Snappiness"
Users transitioning from V13 SP0 to V13 SP1 Update 4 report significantly reduced lag times. While it does consume about 10% more memory and puts your CPU to work, the trade-off is a much more responsive interface when handling multi-instances and complex projects. 3. Critical Safety Fixes
For those using STEP 7 Safety, Update 4 is a non-negotiable. siemens tia portal v13 sp1 update 4 better
Automatic Support: Fail-safe blocks previously marked as "unsupported" are automatically corrected during the project upgrade.
Language Support: Multi-instance tags can now be used consistently across LAD and FBD for safety applications. 4. Expanded Hardware & Simulation
V13 SP1 was the bridge that brought support for S7-1200 V4.0 simulation and the ET 200SP Controller. Update 4 polishes these features, ensuring that the simulator works smoothly without the "ghost" errors common in the early SP1 release. Pro-Tip for Windows 10 Users
If you are running Windows 10, Siemens recommends moving past SP1 and installing TIA Portal V13 SP2. SP1 was never officially compatible with Windows 10, leading to major stability issues that were only resolved in the SP2 release.

TIA Portal V13 SP1 Update 4 is a Critical Performance Milestone
If you are still working with legacy industrial systems or maintaining older PLC projects, you have likely encountered Siemens TIA Portal V13 SP1 Go to product viewer dialog for this item. . While newer versions like V19 offer advanced features, V13 SP1 Update 4
remains a legendary "sweet spot" for engineers due to its significant leap in stability and responsiveness compared to earlier iterations.
Here is a deep dive into why this specific update made the software "better" and why it remains a crucial version for many automation professionals. 1. Drastic Reduction in System Lag
One of the most immediate improvements noted by users upon moving to V13 SP1 Update 4 was a much smoother user interface.
Responsiveness: Lag times during project navigation were greatly reduced. You don’t need a flashy version jump to
Stability: The update improved the stability of running multiple instances of TIA Portal simultaneously.
Resource Trade-off: While the system felt faster, it did come with a slight increase in resource usage, typically requiring about 10% more memory and slightly higher CPU activity. 2. Expanded Hardware & Firmware Support
Update 4 unlocked critical hardware capabilities that were previously restricted. This was the era where the S7-1200 and S7-1500 families were rapidly evolving.
S7-1500 Firmware V1.8: Highlights of this update included better integration for S7-1500 CPUs running Firmware V1.8, which enabled features like sending diagnostic information via email and enhanced security through encrypted communication.
Hardware Catalog: It provided the foundation for Support Packages (HSPs) required for newer modules, such as the SITOP UPS1600. 3. Critical Fixes for "TIA Openness"
For developers using TIA Portal Openness to automate project creation, Update 4 was a mandatory step. It provided essential bug fixes and cumulative improvements for the API, ensuring that scripts for generating hardware configurations or software blocks ran more reliably. 4. Improved Compiler Strictness
While "stricter" might not sound like "better" to some, Update 4 (and SP1 in general) introduced more stringent syntax rules for the compiler.
Safety First: It checked that function values (Return) were written for all possible program paths, reducing the risk of accidental undefined behavior during runtime.
Data Integrity: New rules for READ_DBL and WRIT_DBL instructions in SCL ensured that data types matched across standard and optimized blocks, preventing compilation errors that would have caused issues later in the field. Essential Tips for Your Installation

Still supporting TIA Portal V13 SP1? Update 4 is worth your attention.
While many have moved to newer versions, V13 remains a workhorse for countless installed systems. Update 4 isn’t about new features – it’s about reliability and polish.
✅ Key improvements:
⚠️ Note: Update 4 requires SP1 already installed. No hardware changes, no license update needed.
If you’re maintaining older lines or can’t migrate to V15+ yet, this update reduces daily friction.

Better also means more extensive. TIA Portal V13 SP1 Update 4 extended device support to include:
Without Update 4, you could not commission a S7-1200 V4.2 CPU using TIA Portal V13. This made the update mandatory for any new hardware procurement in 2016–2018.
The single most cited improvement in Siemens TIA Portal V13 SP1 Update 4 is the overhaul of the backend compiler and memory management. Users upgrading from Update 2 or Update 3 immediately noticed:
In benchmark tests conducted by automation forums, a typical mixing plant project compiled in 4 minutes and 20 seconds on Update 3 — but only 2 minutes and 50 seconds on Update 4. That’s a tangible productivity gain.
