MEMORIES AND FILES
1) Turn the file access stop request signal (Xn: arbitrary) from off to on by using
an external input.
2) Stop the file access to the CompactFlash card, and close the opened files.
(Use the QBF_X_In_BitExXm function and the close or fclose function in
programming so that this operation will be performed when Xn turns on.)
3) Unmount the CompactFlash card by using the QBF_UnmountCfCard function.
4) When unmounting of the CompactFlash card is confirmed (the CF CARD LED
is off), the card can be removed.
To confirm the unmount status in the user program, check the "CF CARD LED
status" or "CF CARD status" of the QBF_ReadStatusEx function.
To confirm the unmount status in C Controller setting utility, check "CF CARD"
in the "LED information" area in the <<Module information>> tab.
5) Turn off the file access stop request signal (Xn: arbitrary).
(Xn can also be requested by a pulse input in step 1).)
