Contents of a Memory Card
7.4.1
Initializing a Memory Card
Whenever an SD card is inserted into a CPU module which is supplied with power, or power is supplied to a
CPU module into which an SD card has been inserted, the system initializes the SD card, and a default folder
created in the SD card is named according to the model of the CPU module.
During the initialization of a SD card, if a folder is missing from the default folder group, the system
automatically adds the lost folder. However, if the initialization of a SD card fails, the SD card can not be
initialized again until it is formatted again.
When a memory card is initialized, the SYSTEM LED indicator blinks.
