Installing and Removing the SD Memory Card
Before Using an SD Memory Card
• Keep the following precautions because an SD Memory Card may become unusable.
a) Do not turn OFF the power supply to the Controller while the SD BUSY indicator is lit (i.e., while
SD Memory Card access is in progress).
The SD BUSY indicator is lit when the SD Memory Card is accessed from the user program or
from a computer through FTP.
b) Do not remove the SD Memory Card while the SD BUSY indicator is lit or the SD PWR indicator
is lit (i.e., while SD Memory Card power is supplied).
Press the SD Memory Card power supply switch and confirm that the SD BUSY indicator or SD
PWR indicator is not lit before you remove the SD Memory Card.
• Never insert the SD Memory Card facing the wrong way.
If the SD Memory Card is inserted forcibly, it may become unusable.
• To format the SD Memory Card (e.g., to delete all of the data), insert the SD Memory Card in the
CPU Unit and perform the operation from the Sysmac Studio.
• The SD Memory Card uses flash memory, and so its service life is limited. When the end of the SD
Memory Card’s service life approaches, the ability to write data is lost, and data is sometimes not
retained after writing. The service life depends on the size of the data that is written and on the am-
bient temperature. For the unlikely event that data is lost, it is recommended to periodically back up
data.
• The service life may be extremely short if a non-OMRON SD Memory Card is used. Also, operation
may be affected due to deterioration in writing performance.
• If you use an OMRON SD Memory Card, the end of the life of the SD Memory Card can be detected
in the following ways.
a)
_Card1Deteriorated
(SD Memory Card Life Warning Flag) system-defined variable
b)
SD Memory Card Life Exceeded
