Hi, I m having the same issue for downgrading from 4.5 to 4.3. The CPU is a 1214C 6ES7 214-1AG40-0XB0 FS 13 I can upgrade but no way to downgrade. I have checked the the link and i see no notice or whatever that could explain the rootcause. https://support.industry.siemens.com/cs/de/en/view/107539750 I have a project developped by a 3rd party that was done with TIA Portal V15 and 1214C with defined fw 4.3. My custommer has told me i have to work with this version and now way to leverage to fw 4.5. All the Hw 1214C i have received has fw version 4.5 Note: I have tested an upgrade (4.6) and i have no issues. ------------------------------------------------------------------------------------------ |

Hello Sugreev, CPUs with FS 13 come with firmware V4.5 installed at the factory and a firmware lower than its factory firmware cannot be installed on a CPU. |
