These basic steps to backing up the Yokogawa STARDOM CF (Compact Flash) card.
Click on the Windows Start menu and type cmd to open Command Prompt window. Navigate to the location where the FcxBackup program is stored, and run the FcxBackup program using the following command.

FcxBackup {IP Address of the Yokogawa STARDOM}

A directory called BACKUP will be created in the same folder with all the required files (JEROS and RAMDISK). You will be able to use these directories and files to restore the JEROS program in another CF card (using the FcxRestore program).

Note that your laptop IP address will have to be in the same subnet as the Yokogawa STARDOM RTU/Controller.
