Considerations for using an SD memory card
The following shows the considerations for using an SD memory card.
■Creating files/folders on an SD memory card
Do not insert an SD memory card used for the recording function in a device such as a personal computer to directly edit or
create files and folders.
Otherwise, the function may not run properly.
■SD memory card to be used
Use a supported SD memory card. (Page 31 Supported SD memory cards (sold separately))
If an unsupported SD memory card is used, data in the SD memory card may be corrupted while the system is running or the
system may stop (a module major error (2450H) occurs in a CPU module).
■Turning the power OFF or resetting a CPU module
When turning the power OFF or resetting a CPU module while data is being written to an SD memory card, the writing is not
completed and the file may be corrupted.
Turn the power OFF or reset a CPU module after stopping file access. For the important data, create backups periodically.
If an SD memory card is damaged due to turning the power OFF or resetting a CPU module during writing, format the SD
memory card.
■Removing or replacing an SD memory card
Make sure to stop file access before removing or replacing an SD memory card.
Otherwise, the data in the SD memory card being accessed may be corrupted or a file system failure may occur.
In addition, the status of the SD memory card may be falsely recognized by a recorder module.
If an error occurs in the SD memory card, refer to the following:
MELSEC iQ-R System Recorder User's Manual (Application)
■Formatting an SD memory card
For formatting an SD memory card, use the SD memory card format function of a recorder module. (MELSEC iQ-R
System Recorder User's Manual (Application))
Do not reset a CPU module or turn the power OFF while an SD memory card is being formatted.
■SD memory card life
An SD memory card has a life (a limit on the number of times for writing data). For details, refer to the specification of an SD
memory card to use.
■Write protect switch
When the write protect switch of an SD memory card is locked (write protected), no file can be written.
Make sure that the write protect switch is unlocked (write allowed).
