4.4 Performance Specifications of SD Memory Card
This section describes the performance specifications of the SD memory card.
When using an SD memory card in a C Controller module, refer to the following.
MELSEC iQ-R C Controller Module User's Manual (Startup)
For the performance specifications of the L1MEM-2GBSD and L1MEM-4GBSD, refer to the following.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
Handling precautions
• The operation of the SD memory cards manufactured by Mitsubishi (NZ1MEM-GBSD) has been tested on the MELSEC
iQ-R series modules. If an SD memory card
*1
manufactured by other companies is used, a problem, such as damage to
data in the SD memory card and system operation stop, may occur.
• SD memory cards manufactured by Mitsubishi conform to IEC 61131-2 when being used in a module.
• SDHC-type SD memory 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.)
• All SD memory cards to be used in the CPU module need to be formatted. An SD memory card is unformatted when
purchased. Before using the card, insert it into the CPU module and format it using the engineering tool. Do not format an
SD memory card using a personal computer. ( GX Works3 Operating Manual)
• Data in the SD memory card may corrupt if the following operation is performed while the SD memory card is being
accessed: powering off the system, resetting the CPU module, or removing the SD memory card. If the CARD ACCESS
LED is on, terminate the access to the SD memory card with the SD CARD OFF button, and then power off the system,
reset the CPU module, or remove the SD memory card. The use of the SD memory card can be disabled by SM606 (SD
memory card forced disable instruction) and the disabled status can be checked by SM607 (SD memory card forced
disable status flag).
• Regularly backup important data on other media, such as CDs and DVDs.
*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.
