Hello Experts!

I can go online to and existing, functional project loaded onto a CPU 1517F-3 PN/DP via TIAv18 on my new 2025 PG, Windows 11. The “compare” shows all green dots. However, any attempt to download any function or function block (with or without modification) is foiled by the message “Totally Integrated Automation Portal has encountered a problem and needs to close”. Can anyone please help with that? Many thanks. Have a great day! 

Hello there!

Thanks for your reply.

My updater in the "Help" menu ... shows "Updates are not available for this product". I have searched for updates, but the result is the same. I think, I'm all up-to-date, unless there's some other procedure required for this.

Hi again,

I have tried with a PG with Windows 10 as well, with the same result.

 In TIA, from the top bar select Help -> Installed software... STEP 7 / WinCC V18 Update 5 (10/2024) is the latest update.

Updates for STEP 7 V18, S7-PLCSIM V18 and WinCC V18

Hello Hati,

Thank you for your input. I have installed update 5 to my version of TIAv18 as per your advice. Thereafter everything worked just fine. Many thanks once again.

Cheers, DBME
