10.2 Specifications
This section describes the specifications of SD memory cards.
For the specifications of the L1MEM-
GBSD, refer to Page 650, Appendix 7.
● Use an SD memory card manufactured by Mitsubishi (NZ1MEM-GBSD).
*1
Using a non-Mitsubishi SD memory card may cause a problem, such as damage of data in the SD memory card and
system stop.
● Do not format an SD memory card using a personal computer.
● SD memory cards manufactured by Mitsubishi conform to IEC 61131-2 when being used in a CPU module.
● SDHC-type cards can be used only with CPU modules that support the use of those cards. (An SDHC logo is shown on
the module or the support is described in the manual.)
● Performing any of the following operations, powering off the system, resetting the CPU module, or removing the SD
memory card, while the SD memory card is being accessed may damage data in the SD memory card. Stop access to
the SD memory card, and then perform these operations. ( Page 100, Section 4.6 (2))
Using SM606 (SD memory card forced disable instruction) and SM607 (SD memory card forced disable status flag) can
disable the SD memory card or check the SD memory card disabled status.
● Regularly back up important data by saving them to other media, such as a CD and DVD.
*1 For commercially available SD memory cards, refer to the following.
Before using a commercially available SD memory card, check that the card does not affect the control of the target
system.

10.3 Handling
(1) Formatting an SD memory card
An SD memory card must have been formatted to be installed to the CPU module. Since the SD memory card
purchased is not yet formatted, format it using a programming tool before use.
For formatting, refer to the following.
GX Works2 Version 1 Operating Manual (Common)
(2) Storable files
For the files that can be stored on SD memory card, refer to the following.
