Web server on CPU 1214C V4.1 crashed after 48 hours. Fix in Update 4: Memory leak in the web server process resolved.
: By 2021, TIA Portal v13 SP1 was largely out of official support. Users were encouraged to move to v13 SP2 to maintain compatibility with Windows 10 security updates. siemens tia portal v13 sp1 update 4 better 2021
: Some engineers consider V13 SP1 (along with V15.1) to be among the most stable releases in the TIA Portal history, often preferring it for stable industrial plants that do not require the overhead of newer, more resource-heavy versions. Performance vs. Compatibility Update 4 Improvements Web server on CPU 1214C V4
There are typically no additional license costs for converting from V13/V13 SP1 to V13 SP2. Latest Cumulative Updates: Users were encouraged to move to v13 SP2
You cannot program a new S7-1200 G2 (Firmware 4.4 or 4.5) with V13 SP1 Update 4. If your 2021 project required a new CPU order number (6ES7...), you were forced to upgrade.
Software is like wine; some vintages peak late. By Update 4, Siemens had stopped developing V13. This meant no new bugs were being introduced. For a frozen production line, this is ideal. The update was the most debugged version of the V13 kernel available.
