Why TIA Portal V13 SP1 Update 4 is Better for Your Automation Workflow is than preceding versions like V13
: Any F-blocks previously marked as "Unsupported Blocks" in older versions are automatically supported after upgrading a project to V13 SP1 Update 4. Stability and Bug Fixes Why TIA Portal V13
: TIA Portal V13 SP1 is officially not compatible with Windows 10 . If your engineering station runs Windows 10, Siemens recommends using TIA Portal V13 SP2 , which supports the newer OS and allows you to open V13 SP1 projects directly without a license upgrade. Summary Table: V13 SP1 Update 4 vs. Previous Versions Improvement in Update 4 System Response Drastically reduced lag times and smoother interface. Safety Blocks Automatic support for previously "unsupported" F-blocks. Programming Expanded use of multi-instance tags in LAD/FBD. PLC Memory Optimized instructions (TON, TOF) consume less PLC space. Stability Cumulative fixes for crashes found in Updates 1-3.
Update 4 introduced several technical improvements that simplify complex programming, particularly for fail-safe applications:
For those maintaining machines that require V13, Update 4 is widely considered the "sweet spot" for performance before moving to the SP2 or V14+ environments.
