The value in the user s manual for the device takes priority if it is written. Write Protection You will not be able to write to the SD Memory Card if the key is set to the LOCK position. (Use this setting to prevent overwriting.) Detecting SD Memory Card Life Expiration You can detect the remaining life of the SD Memory Card used in a NJ-series Controller. The remaining life can be notified with the following functions. System-defined variable Card1Deteriorated (SD Memory Card Life Warning Flag) SD Memory Card Life Exceeded (Observation) event For details, refer to the NJ-series CPU Unit Hardware User s Manual (Cat. No. W500). Precautions for Correct Use Read the following precautions carefully before using an SD Memory Card. For details, refer to user s manuals for the device on which the card is mounted. Formatting The SD Memory Cards are formatted and shipped, so you do not need to format the card by yourself after purchasing. To format the SD Memory Card after using, perform the formatting operation on the device on which the card is usually mounted. Service Life 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 ambient temperature. For the unlikely event that data is lost, it is recommended to periodically back up data. Installing and Removing To install and remove the SD Memory Card, follow the user s manuals for the device on which the card is mounted. Never remove the SD Memory Card while it is accessed. Otherwise the data may not be written correctly, or at worst, the card may no longer be usable. 2
