10.3 micro SD File System
In North America, XLE/XLT prior to Rev TA supported the FAT16 file system which allows up
to 2.0 GB of flash memory, while XLE/XLT with REV TA and higher support the FAT32 file
system which allows up to 2TB of flash memory. FAT microSD cards are compatible in REV TA
units and higher. The XLEe and XLTe also support the FAT32 file system.
In Europe, the new XLE starts at Rev RA and XLT starts at Rev KA.
The microSD Memory Card slot uses the PC-compatible FAT32 File System. This means that a
PC, with a microSD-compatible card reader, can read files that have been written by the
XLE/XLT and can write files that can be read by the XLE/XLT.
The XLE/XLT 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 eight (8) characters,
followed by an optional dot, and an optional extension with up to three (3) characters.
Directories and sub-directories may be nested up to 16 levels deep as long as each pathname
string does not exceed 147 characters.
10.4 Using the Removable Media Manager
The Removable Media Manager is an interactive XLE/XLT screen that performs the following
functions:
•
Display number of total and free bytes
•
Browse file and directory lists
•
Delete files and directories
•
Format a microSD card
•
Load and save application programs
•
View screen capture bitmaps
The Removable Media Manager can be accessed via the System Menu (see
Chapter 9
) or by
using Cscape to place a Removable Media Manager object on an application graphics screen.
10.5 Using Removable Media to Log Data
Using Read and Write Removable Media function blocks, an application ladder program can
read and write XLE/XLT 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.
