Auto Upload to SD Memory Card
When there is no ZLD file to download on an SD memory card with an autoexec.ini file that executes a download, an upload can
be executed instead of a download.
By using the auto upload function, the data uploaded from the CPU module can be copied to other CPU modules without having to
edit the SD memory card or autoexec.ini file during the process.
To perform an auto upload, it must be enabled in the autoexec.ini file that executes a download. For details, see "Creating the
autoexec.ini File" on page 11-27.
Example 1: When there is no ZLD file on the SD memory card
All data will be uploaded and a ZLD file will be created.
