(2) When using an SRAM card
Up to 1018K points can be stored in one file.
Since one block consists of 32K words, up to 32 blocks can be stored.
Note that the number of points or blocks that can be added depends on the size of the programs and device
comments stored in the memory card.
(3) When using a Flash card
Up to 1018K points can be stored in one file.
Since one block consists of 32K words, up to 32 blocks can be stored.
Note that the number of points or blocks that can be added depends on the memory card capacity and the size of
the programs and device comments stored in the memory card.
