The verdict: Use TIA Portal V13 SP1 Update 4 if and only if you are maintaining existing equipment that cannot be upgraded. It is the most stable version of V13 SP1. However, do not start new development on it.
Do:
Do Not:
For greenfield projects or major retrofits, invest in TIA Portal V18 or V19. But for the thousands of production lines still running on SIMATIC S7-1500 V1.8 and WinCC V13, Update 4 remains the gold standard of stability.

TIA Portal V13 SP1 Update 4
This refers to a specific older version of Siemens' engineering framework, Totally Integrated Automation Portal.
Here is a breakdown of the version string:
Important Context: This version is considered legacy software. Modern projects are typically developed in TIA Portal V16, V17, V18, or V19. You generally cannot open a project created in V13 SP1 Update 4 with a newer version (like V16) without performing a project migration, and older hardware firmware may require updates to work with newer portal versions.
TIA Portal V13 SP1 Update 4 is a maintenance update released for the V13 SP1 branch. Its purpose is to correct known defects, address stability and performance issues, and add limited functional improvements and device support that were not present in earlier service packs. Rather than introducing major new features, Update 4 focuses on reliability, interoperability, and bug fixes across the TIA Portal toolset (STEP 7, WinCC, Startdrive, and associated libraries).

While Update 4 is primarily a stability and bug-fix release, it introduced several noteworthy enhancements:
It’s a maintenance update for Siemens engineering software (STEP 7, WinCC, Startdrive) used to program S7-1200, S7-1500, S7-300/400, HMI panels, and drives.

TIA Portal V13 SP1 Update 4 serves as a historical bookmark in Siemens automation history. It represents the mature, stable conclusion of the first major "New Generation" TIA Portal architecture.
While it is considered obsolete and unsupported by the vendor today, it remains installed in many "brownfield" sites where machinery was commissioned between 2015 and 2017. For modern engineering requirements, upgrading to a supported version (TIA Portal V17/V18/V19) is strictly recommended to ensure hardware compatibility, cyber security, and vendor support.
Report Classification: Technical Overview Intended Audience: Automation Engineers, System Integrators, Plant Managers.
TIA Portal V13 SP1 Update 4 was a stability and performance release for the Siemens engineering framework, released in mid-2015. It was eventually superseded by higher updates (up to Update 9) and later versions like V13 SP2 and eventually newer major versions like V19 and V21. Core Updates & Improvements The verdict: Use TIA Portal V13 SP1 Update
Update 4 focused primarily on refining the user experience and fixing bugs reported in the initial SP1 release:
Engineering Stability: Improved stability when working with large projects and multiple editors.
Hardware Compatibility: Enhanced support for new S7-1200 and S7-1500 firmware versions.
Performance: Faster compilation times for S7-1500 controllers and optimized HMI screen loading.
Security: Minor security patches for communication between the engineering station and PLCs. Important Installation Notes
Cumulative Nature: Updates for TIA Portal are cumulative. You do not need to install Updates 1, 2, or 3 before applying Update 4; the latest update always contains all previous fixes.
Prerequisites: You must have TIA Portal V13 SP1 (Service Pack 1) installed before applying this update.
Archiving: Projects created or updated in this version use the .ap13 format and can be archived as .zap13 files. Version Lifecycle & Migration
While V13 SP1 was a long-term stable release, it is now considered legacy:
OS Support: V13 is generally optimized for Windows 7 and Windows 8.1. It is not officially supported on Windows 11, which requires newer versions like V17 or higher. Do Not:
Modern Alternatives: If you are testing features, Siemens offers a 21-day trial for TIA Portal Cloud which allows you to use newer versions without local installation.

TIA Portal V13 SP1 Update 4 is widely regarded as a significant "turning point" for the stability and usability of the Siemens V13 engineering platform. Why Update 4 is a "Good Story"
For engineers who struggled with early versions of TIA Portal, Update 4 (released around August 2015) brought critical improvements:
Restored Performance: After installing V13 SP1, many users found their classic Step 7 (v5.5) slowed down significantly. Update 4 was the patch that finally returned system performance to "normal" speeds and made TIA Portal noticeably faster and more stable.
Connection Stability: It resolved a frustrating bug where TIA would crash if a laptop went into sleep mode while connected to a PLC.
Communication Enhancements: The communication module was refined, making multi-instance sessions (running several TIA windows at once) far more responsive.
Better Simulation: PLCSIM became more reliable for testing smaller programs, though users noted it could still be a heavy load on the first CPU thread. Essential Context for Today
