1.9 Precautions
• For projects that use external memory devices, always insert the external memory device before turning the
MICRO/I on.
• The maximum number of screenshots that can be captured can be set in HMI Special Data Register LSD65.
• External memory devices have a limitation on the number of writes allowed.
Regularly backup data on the external memory device.
• Never turn the power off to the MICRO/I or remove the external memory device while reading/writing to it.
Otherwise, the data on the external memory device may be destroyed. Should this occur, reformat the external
memory device.
• When external memory device is inserted into the MICRO/I, first perform the following operations, and then turn
off the power to the MICRO/I or remove the external memory device.
• When a read or write failure occurs with the external memory device, HMI Special Data Register LSD42 for a USB
flash drive
inserted in USB1 or an SD memory card
and HMI Special Data Register LSD33 for a USB flash
drive
are set with the error status. For details about the error, refer to Chapter 33 “HMI Special Data Register
(LSD)” on page 33-8. Manually delete the files by using a computer or the File Manager function.
• If an unusable external memory device is inserted, the following error message appears.
• If your computer does not have an SD memory card slot, a docking station is required to read/write to the SD
memory card.
• Multiple USB flash drives cannot be used at the same time.
• Do not connect the USB flash drive to the MICRO/I through a USB hub.
• The message “Stopping external memory” appears while reading or until writing stops.
To resume reading or writing to the external memory device, re-insert it.
• Altering folders and files in the External Memory Device folder on the external memory device will make the
external memory device unusable in MICRO/I and WindO/I-NV4.
