STEP 7 (TIA Portal): Migrate quickly Originating From Tia 11 Towards Tia 15.1 ?

Hello 
I have got around 30 PLC to upgrade programs (and plc too) from TIA 11 to TIA 15.1
Is there a quick way to do it ? a Siemens tool ?
(I Don't want to do it manually from each plateform : TIA 12-13-15....)
Thanks

Upgrading PLCs from TIA Portal V11 to V15.1

Hello, upgrading 30 PLCs and their programs from TIA Portal V11 to V15.1 can be streamlined using Siemens tools. Manual upgrading through each intermediate TIA Portal version (V12, V13, V15) is indeed time-consuming.

Here's a recommended approach:

  1. Use the "Open in Previous Version" feature: TIA Portal V15.1 can directly open projects created in TIA Portal V11. After opening, you will be prompted to convert the project.
  2. Project Conversion & Compatibility Check: After opening in V15.1, perform a thorough compatibility check. Address any reported issues before proceeding.
  3. Batch Conversion (Consider): While not fully automated, you can organize projects and convert them in batches within V15.1.
  4. Upgrade PLC Firmware: After program conversion, ensure the PLC firmware is compatible with TIA Portal V15.1. Use Siemens Industry Online Support to find the latest firmware for your specific PLC models.

Important Resources:

For extensive projects and potential complexities, consider engaging Siemens Professional Services for assistance.
