I have just encountered the same error with a S7-1215C after months of usage. Part of my diagnostic buffer (see attached file for complete buffer): 1 of 50; Event ID: 16# 02:401A CPU info: Serious firmware exception (not relevant for user, system code: 16#00644A4E 16#10000034 16#080D0000) |> CPU changes from RUN to DEFECTIVE mode |> HW_ID= 52 - Operating mode control I have tried to power cycle the CPU, but the problem reappears as soon as I try to download a hardware configuration. I have just tried with a totally fresh and empty project as well. And with and without the memory card inserted. I wonder if the error is related to this: -I did try to upgrade the firmware about a week ago from the CPU web page, but it kept on failing after a few minutes of uploading:
I wonder if a 8 MB SMC card is necessary, as the firmware file is on 5 MB, and I only have a 2MB SMC (the black Siemens Memory Cards 954 series). Do I need a memory card to upgrade the firmware? It doesn't say on the firmware pages.

I just succeeded upgrading the firmware to V3.0.2 using a 24 MB SMC card, and it seems like the problem is gone. |
