9.3 Micro SD File System
The Micro SD Memory slot uses the PC-compatible FAT16 File System. This means that a PC, with a
Micro SD-compatible card reader, can read files that have been written by the XL6/XL6e OCS and can
write files that can be read by the XL6/XL6e OCS.
However, the XL6/XL6e OCS does not support long filenames, but instead implements the 8.3 filename
format. This means that all file and directory names must consist of up to 8 characters, followed by an
optional dot, and an optional extension with up to 3 characters.
Directories and sub-directories can be nested up to 16 levels deep as long as each pathname string does
not exceed 147 characters.

The Removable Media Manager can be accessed via the System Menu or by using Cscape to place a

Using Removable Media to Log Data
Using Read and Write Removable Media function blocks, an application ladder program can read and
write XL6/XL6e OCS register data in the form of comma-delimited files, with a .CSV extension. These
files are compatible with standard database and spreadsheet PC programs. In addition, an application
ladder program can use Rename and Delete Removable Media function blocks to rename and delete
files.
