S7 Mmc

I am pretty sure that there is a kind of boot-strap OS in the S7-300 CPUs. And the boot-strap OS will detect a Siemens MMC card and if there is a firmware update. If found it loads the firmware update into its internal flash memory.

You always need a Siemens MMC card in an S7-300 CPU, even a small 64 kB will do. For a firmware update it has to be the 4MB size which is expensive.

These are SMC cards, not MMC cards.
SMC cards can be formatted in an S7-1500 CPU.
In TIA and when connected to the PLC, browse to the PLC via 'accessible devices', open 'online and diagnostics' .. 'Functions' .. 'Format Memory Card'.
