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

9.5 Using Removable Media to Log Data
Using Read and Write Removable Media function blocks, an application ladder program can read and
write XL7 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.
9.6 Using Removable Media to Load and Save Applications
A special file type, with a .PGM extension, is used to store XL7 OCS application programs on MicroSD.
To load an application from MicroSD to the XL7 OCS, use the Removable Media Manager (open the
Removable Media Manager in the System Menu) to find and highlight the desired .PGM file, and then
press the Enter key.
To save an application from the XL7 to MicroSD, open the Removable Media Manager in the System
Menu and press the Save Pgm function key. The application will be saved in a file called
DEFAULT.PGM in the MicroSD root directory.
NOTE: Saving an application to MicroSD can only be done from the Removable Media System
Menu and is not available on a Removable Media Manager object that was placed on an
application graphics screen by Cscape.
