When removing or replacing the SD memory card
• Make sure to stop file access before removing or replacing the SD memory card.
(
Page 65 File access stop processing method)
• Not following the procedure may cause a loss of logging data during processing, corruption of data in the SD memory card
that is being accessed, a file system error, or false recognition of the mounting status of the SD memory card.

• If an error occurs on the SD memory card, refer to the following manual.
(
MELSEC iQ-R High Speed Data Logger Module User's Manual(Application))
• High speed data logger module settings are saved to the SD memory card. Therefore, the high speed data logger module's
IP address returns to the initial status (192.168.3.3) when the SD memory card is not inserted in the module or when the
power is turned OFF to ON or the CPU module is reset, without the settings written to the SD memory card. When
necessary, read the current settings before removing the SD memory card and after replacing the card, promptly write
those settings to the new card.
■
SD memory card capacity
• Access speed to the SD memory card is affected by the amount of saved files. In particular, access speed becomes
extremely slow when files are saved up to the capacity limit of the SD memory card. Use the SD memory card maintaining
10% or more free space on the card.
• A minimum size occupied by the files on the hard disk varies depending on the SD memory card capacity. Therefore, the
actual file size and the occupied file size on the hard disk may differ.
■
SD memory card diagnostic time
• The high speed data logger module performs diagnostics (file recovery, etc.) of the inserted SD memory card contents at
the times listed below.
When powering OFF to ON or resetting the CPU module
When inserting an SD memory card while the power is ON
• The SD memory card diagnostic time takes longer when there are more files on the card. 100 files takes approximately 5
seconds, and 1000 files takes approximately 10 seconds.
• When many files are saved on the SD memory card, the following operations require longer time. Delete unnecessary files.
'SD memory card status' (X1) startup time
Time before the high speed data logger module can start processing ('Module READY' (X0) or 'Module operating status'
(X5) startup time)
■
Formatting SD memory card
• Use the format function of the configuration tool to format an SD memory card.
• Do not format an SD memory card using the format function of Windows.
• Do not reset the control CPU or turn the power OFF when formatting an SD memory card.
• High speed data logger module settings are saved to an SD memory card. Therefore, all settings are lost when formatting
the SD memory card. When necessary, read the current settings before formatting, and promptly write those settings after
formatting. The IP address of the high speed data logger module returns to the initial status (192.168.3.3) when turning the
power OFF to ON or when resetting the module without writing the settings to the SD memory card.
