Appendix 4 SD Memory Card
Part names
An SD memory card is installed in the CPU module to operate the module based on the project data in the card.
Specifications
The following shows functional specifications of the SD memory card.
For L1MEM-2GBSD and L1MEM-4GBSD, refer to the following.
(QCPU User's Manual(Hardware Design, Maintenance and Inspection)
Handling of the SD memory card
• Operational compatibility of the SD memory cards manufactured by Mitsubishi (NZ1MEM-2GBSD and NZ1MEM-4GBSD)
with MELSEC iQ-F series CPU modules has been checked. Use of SD memory card other than a Mitsubishi SD memory
card may result in loss of the data stored in the SD memory card, or problems such as system stop.
• When mounted in the CPU module, SD memory cards manufactured by Mitsubishi are compliant with IEC61131-2.
• The SDHC memory card can be used only with devices with an SDHC logo or whose user's manual lists an SDHC logo.
Note that SDHC cards cannot be used with devices that support only "SD" specifications.
• Turning off or resetting the CPU module or removing the SD memory card while the card is being accessed may corrupt the
data in the SD memory card. Always turn off or reset the CPU module or remove the SD memory card after disabling
access to the SD memory card. With SM606 (SD memory card forced disable instruction) and SM607 (SD memory card
forced disable status flag), the SD memory card can be disabled and its usage status can be checked.
• It is recommended that important data be periodically backed up to CD, DVD, or other media.
Formatting
To use any SD memory card in the CPU module, the card must be formatted. In the initial state after purchase, the SD
memory card is not formatted. Insert the SD memory card to a CPU module and format the SD memory card using the
engineering tool before use. Do not format the SD memory card using the personal computer. (GX Works3 Operating
