You could downgrade the firmware again and try if it works: https://support.industry.siemens.com/cs/ch/de/view/92274475 |

That ended up working, thanks. I did some testing, and the card is only compatible with firmware version 1.7. Versions 1.8.1-1.8.3 all give me the same error. Very strange.

Maybe you just discovered a compatibility problem between 1.7 and 1.8.x. If you would contact Siemens the problem could be analyzed in detail. Of course they would need your memory card content. But it seems you need to stick to 1.7 or migrate to 1.8.x via a new download into the PLC. Before the download I would recommend to delete all project data from the memory card or maybe to format the memory card. This should work without a need to recompile the project. However your configuration would still contain a V1.7 PLC. I assume this step would repair your memory card problem. Alternatively or in a second step you may consider changing the configured PLC from 1.7 to 1.8 then recompile and then download so that you would be able to use new features of V1.8.x.
