This MMC cannot be used together with CPU 312C or CPU 312.
Maximum number of loadable blocks in the MMC
The number of blocks that can be stored on the MMC depends on the capacity of the MMC
being used. The maximum number of blocks that can be loaded is therefore limited by the
capacity of your MMC (including blocks generated with the "CREATE DB" SFC):
Table 7-2 Maximum number of loadable blocks on the MMC
Size of MMC Maximum number of blocks that can be loaded

Here the maximum number of blocks that can be loaded for the
specific CPU is less than the number of blocks that can be stored on
the MMC.
Refer to the corresponding specifications of a specific CPU to
determine the maximum number of blocks that can be loaded.
