: Newer Siemens hardware, such as S7-1200 CPUs with firmware V4.5, often requires more modern software versions like V17 for full engineering support. Summary: Is it still "Better" in 2021?
Understanding project compatibility is essential for organizations managing a mix of legacy and modern systems.
TIA Portal V13 SP1 Update 4 in 2021 is . It is not "better" by any objective measure – only possibly necessary for legacy support. Siemens itself recommends migrating to V17+ for any active development. Modern TIA Portal : Because it is out
V13 SP1 U4 lacks all of these.
For any new development or modernization project in 2021, V13 SP1 Update 4 was objectively inferior to newer versions.
Compared to previous versions of TIA Portal, v13 SP1 Update 4 offers several advantages, including:
