The question of whether it was “better” in 2021 depends entirely on context. For engineers maintaining legacy systems, V13 SP1 Update 4—or better yet, V13 SP2 Update 4 with Windows 10 support—remained a necessary and functional tool. However, for new development or modernization projects, the balance clearly tipped in favor of current releases like V15.1 (widely praised for stability), V16 (with its intuitive UI and enhanced communication), V17 (with industrial 4.0 features), or the even more recent V18, V19, and V20 versions.

: Some older hardware components may not have been fully supported by later TIA Portal versions. Users working with legacy S7-300/400 systems or older HMI panels might find that V13 SP1 offered the optimal compatibility. siemens tia portal v13 sp1 update 4 better 2021

Released as a critical refinement to the V13 ecosystem, Service Pack 1 Update 4 brought sweeping stability improvements that fixed major performance bottlenecks seen in earlier V13 iterations.

However, the update was not without its headaches. The installation process itself drew criticism: “The uninstall and (especially) the installation was a pain. Mostly because of the lack of accurate progress feedback. At some point you have to check if the LOG file is growing in size before knowing that ‘2 minutes’ left is not a ‘software freeze’… just inaccurate prediction”. The question of whether it was “better” in

: For organizations with multiple engineers working on a common codebase, maintaining consistency in software versions prevents compatibility conflicts and workflow disruptions.

: If migrating old Step 7 V5.5 projects, utilize the built-in migration tool in V13, which handles older hardware better than V16 does. : Run V13 inside a Windows 7 Pro

If you were still running TIA Portal V13 SP1 in 2021, Update 4 could be meaningful in these ways:

Faster generation of block code for S7-1500 controllers.
