Data transfer operations can be performed for projects from the CX-Program-
mer to transfer all of the above files (symbol table files, comment files, pro-
gram index files) between the CPU Unit and a Memory Card or between EM
file memory. (Program index file transfers are supported starting from version
2.0.) The symbol table files and comment files can also be transferred
between the CX-Programmer, computer RAM, and a data storage device with
CX-Programmer version 1.2 or higher.
Files are formatted in DOS, and therefore can be used as regular files on a
Windows computer.
Files are identified by file names and extensions, as shown in the following
table. A file name is written using the following characters: Letters A to Z,
numbers 0 to 9, !, &, $, #, `, {, }, –, ^, (, ), and _
The following characters cannot be used in file names: ,, ., /, ¥, ?, *, ", :, :, <, >,
=, +, space, and 2-byte characters.
The filename extensions depend upon the type of file being stored. Data files
can have extensions IOM, TXT, CSV, or IOR. (TXT, CSV, and IOR extensions:
Not supported by CS-series CS1 CPU Units that are pre-EV1.) Program files
have the extension OBJ and parameter files have the extension STD. The
location of a file in memory can be specified in the directory, and a directory
can be up to 5 subdirectories deep (counting the root directory).
