Reads a file from a Memory card, in FAT format, into Flash
ROM.
(2) Checking a file (series and edition) in Flash ROM
(3) Checking a file (series and edition) in Memory card
(4) Deleting a file from Flash ROM
(5) Deleting a file from Memory card
(6) Saving a file in Flash ROM to a Memory card
(7) Batch saving and restoration of files of parameters and programs
backed up by battery (SRAM area), to and from a Memory card
(8) Formatting of a Memory card
This manual describes the activation of the Boot System, as well as
the screen displays and operation for the functions listed above.
CAUTION
1 This control unit supports the use of a Memory card as an input/output device. The
following Memory cards are available:
SRAM Memory card
Flash card
Flash ATA card
See the order list for details of the supported Memory card types.
2 On a Memory card, only those files that are in the root directory can be accessed for
display, reading, and writing. Those in subdirectories cannot be used.
3 The time required to read or write each data item varies depending on the Memory
card type, the status of use, and other factors.
4 For Flash cards, only those recommended by FANUC can be accessed for writing.
For reading, they can be usually be used in the same way as SRAM cards as long as
the FAT format is used.
When using a Flash card, note that the card capacity decreases by 128 KB.
A Flash memory card does not allow deletion of files one at a time. It is necessary to
delete all files on the card at a time.
5 For Flash ATA cards, only those recommended by FANUC are available.
6 When formatting a Flash ATA card, use the quick formatting method, which clears
the file allocation table and the directory information on the root directory. An
unformatted Flash ATA card cannot be used without being formatted with a personal
computer.
