Hello
You cannot use a standard SD/MMC card in the S71200 or any Siemens PLC.
The offical Siemens units ave a header written into them, that cannot be written to using a standard PC card writer.
You can use a Siemens Field unit that will use the official Siemens cards, or by using a standard PC with IMG R/W tool but you will have to have another original Siemens card , otherwise the PLC detects and looks for the unique header , if it cannot see it, the PLC will not run,
Sorry but unless you know , or anyone else, can find out, never been possible..
