Officially, Siemens discontinued V13 support in 2019. However, in 2021, you could still obtain Update 4 via:
: Use a dedicated Windows 7 SP1 64-bit or an early corporate build of Windows 10 (such as LTSB/LTSC editions) inside the VM.
: TIA Portal V13 SP1 is officially not compatible with Windows 10 .
: 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 siemens tia portal v13 sp1 update 4 better 2021
While 2021 belonged to TIA Portal V16 and V17, remained a critical tool for the legacy engineer. It represented the moment Siemens stabilized the TIA transition, and for many, it remained the "better" choice purely for its speed and reliability on older hardware. Just remember: for new projects, the future had already arrived.
Operating a software package released in the mid-2010s on modern hardware creates distinct compatibility bottlenecks. Windows 10 Host OS Support
If you try to open a project created in V14 or later, V13 will refuse. Officially, Siemens discontinued V13 support in 2019
Noticeable optimization in data block tracking and screen transitions relative to V13 SP0.
It addresses major memory leaks that caused crash-to-desktop errors.
Siemens allows multiple versions of TIA Portal to coexist on a single operating system. You can install V13 SP1 Update 4 side-by-side with V17 or V18 on Windows 10 (64-bit Professional or Enterprise), provided you verify the specific Windows build compatibility via the Siemens Compatibility Tool. This allows field technicians to service brand-new machinery and decade-old legacy lines using the same engineering laptop. When Should You Upgrade? : A major benefit of this version is
Older G120 and S120 drive profiles are natively integrated without needing complex GSDML files. 2. Peak Stability and Bug Fixes
Seamless configuration of Comfort Panels and Basic Panels.
A major benefit of TIA Portal V13 SP1 Update 4 is its role as a "bridge version" for legacy STEP 7 V5.5 projects moving toward modern platforms.
If you are using any Siemens controller, HMI, or drive released , V13 cannot program or configure it.
Around 2021, many industrial computing environments were strictly standardized on Windows 7 or early builds of Windows 10. Update 4 resolved severe stability bugs, memory leaks, and communication errors specific to those operating system environments. It ensured that automated compilation routines wouldn't crash during critical plant shutdowns. Key Technical Improvements in Update 4
