1.8 Precautions
For projects that use memory cards, always insert the memory card before turning the MICRO/I on.
The maximum number of screenshots that can be captured can be set in HG Special Registers LSD65.
Memory cards have a limitation on the number of writes allowed. Regularly backup data on the memory card.
Never turn the power off or remove the memory card while reading/writing to it. Otherwise, the data on the
memory card may be destroyed. Should this occur, reformat the memory card.
Perform one of the following actions before turning power off to the MICRO/I, or removing the memory card.
- After setting HG special relay LSM20 to 1, check that HG special relay LSM21 is 0. Then remove the memory
card.
- For models HG2F/3F/4F, press the Access Pause button. The Access Lamp begins to blink and when reading/
writing to the CF card stops, the lamp goes out. Then, remove the CF card.
When a read/write failure occurs with the memory card, HG special register LSD42 is set with the error status. For
details about the error, refer to Chapter 32 “2 Internal MICRO/I Devices” on page 32-2.
If your computer does not have a memory card slot, an external memory card reader is required to read/write to
the memory card.
If an unusable memory card is inserted, the error message “This CF card (SD Memory Card) not available” appears.
Altering folders and files in the Memory Card Folder on the memory card will make the memory card unusable in
MICRO/I and WindO/I-NV2.
