1. The following backup files can be created only when using CS/CJ-series
CPU Units with unit version 3.0 or later.
Symbol table files, comment files, and program index files
These files are automatically created from the files in either the Memory
Card, EM file memory, or comment memory.
2. One example of the CPU Bus Unit settings would be the Data Link Tables.
Refer to the operation manuals for specific Units for other setup data.
These files are automatically generated when data is downloaded using the
CX-Programmer version 5.0 or higher. The file names are fixed.
When CX-Programmer version 5.0 or higher is used with a CPU Unit with unit
version 3.0 or later, either of the following memory options can be selected as
the transfer destination for these system files when transferring projects.
• Memory Card
• EM file memory
• Comment memory (in the CPU Unit's flash memory)
Note With CX-Programmer version 4.0 or lower, these files cannot be stored in
comment memory, even if a CPU Unit with unit version 3.0 or later is being
used.

Note With CX-Programmer version 1.2 or higher, the symbol table files and com-
ment files in the above table can be transferred online between the CX-Pro-
grammer and personal computer RAM and between the personal computer
RAM and the memory storage device.
It is possible to access files in subdirectories with CS/CJ-series PLCs, but
Programming Consoles can access files only when they are in the root direc-
tory. The maximum length of a directory path is 65 characters. Be sure not to
exceed the maximum number of characters when creating subdirectories in
the Memory Card with a program such as Windows.
