Simatic Micro MMC card only for Simatic S7 controllers.
They have their own format that Windows does not understand – so if you insert the card into the card reader. It will not appear in Explorer but will appear in the Disk Maintenance Manager. As 4 unformatted partitions. Windows will offer to format the card under FAT !!! It is not necessary to agree with such a tempting offer to spoil the map.
Pay attention to the number of memory cards = from 64 kb, but they are very expensive.
The Simatic card has a factory-written PNM identifier. By which the S7 controller identifies the card as its own Simatic S7-300 MMC_Card.pdf.
Ordinary household MMC cards do not have this identifier and therefore the controller spits them out. The card has its own original format not understood by Windows. Formatted to use 4 reserved memory areas to ensure card survivability.
In Case of Accidental Formatting Simatic S7-300 on A Windows Computer
you can correct the situation by uploading the original image through a household card reader and the WinHex or ImgWr direct recording program.
Similarly, you can capture images for archiving or cloning.
Data of service registers that distinguish Siemens cards from others Since progress does not stand still, cards of the same size, for example, 64 KB, record cards of different physical sizes from 16 to 128 MB (old stocks are over and they are taken from what is at hand). For one type, you can use the smallest image or what is available, and ignore Win Hex warnings about the discrepancy between the physical size of the card.
At the same time, it is impossible to deceive the controller by writing an image from a 4 MB card to a 64 KB card – the controller determines the maximum logical size by the PNM card identifier, which no one has managed to change so far.
There were several topics on the official site about restoring cards – if it doesn’t work, try asking around there. Maybe someone will post a new image. From my experience, I will write that there were no problems with restoring images via Win Hex (with the correct serial number).
Pay attention to the real size of the card – smaller images can be written on large cards, otherwise, it will not work. Recently, Siemens somewhere got small cards for new cards 🙁
