File Memory Section 5-1
Files Used When Transferring without the Parameter File
Note Early versions of the CS/CJ-series CPU Units (CPU Units without a unit ver-
sion number) do not support the files shown in the table above, which are
transferred in an automatic startup transfer without the parameter file.
Backup Files These files are transferred between the Memory Card and CPU Unit during
simple backup operations. The file name is fixed as BACKUP@@. Files
marked with a circle must exist in the Memory Card when performing a simple
backup read (writing from the Memory Card to the CPU Unit).

(Contains the specified
number of words of data
beginning at D00000.)
• The contents is the same as that of

Type Name Description Explanation
Program file BACKUP
.OBJ
User program Contains the programs in the CPU Unit's cyclic and
interrupt tasks.
Parameter file BACKUP
