S7-1200 CPU only supports the memory cards that have been preformatted by Siemens manufacturer, whose order numbers are shown in the table below:
Order number |
Capacity |
6ES7 954-8LF01-0AA0 | 24MB |
6ES7954-8LC01-0AA0 | 4MB |
6ES7 954-8LB01-0AA0 | 2MB |

If SIMATIC memory card is reformatted by Windows formatting program, CPU will not be able to use this reformatted memory card.

At present, S7-1200 still cannot help the memory card realize such advanced functions as recipe and data archiving.
