8-3-4 FTP Client Communications Instructions
FTP client communications instructions are used to transfer files via FTP from an NJ-series CPU Unit to
computers or Controllers at Ethernet nodes.
The files on the SD Memory Card are read and written when the following instructions are executed.
A CPU Unit with unit version 1.08 or later and Sysmac Studio version 1.09 or higher are required
to use the FTP client communcations instructions.
You can read and write files on the SD Memory Card via EtherNet/IP by sending FTP commands to the
built-in EtherNet/IP port from an FTP client.
Refer to the NJ-series CPU Unit Built-in EtherNet/IP User’s Manual (Cat. No. W506) for details.
You can perform file operations from the Sysmac Studio for the SD Memory Card inserted in the CPU Unit.
In addition to Controller files, you can also store document files or other files on the SD Memory Card.
You can determine the remaining life of the SD Memory Card before the Card becomes physically dete-
riorated.
You can determine the remaining life of the SD Memory Card with the following functions.
• System-defined variable _Card1Deteriorated (SD Memory Card Life Warning Flag)
• SD Memory Card Life Exceeded (Observation) record in the event log
The life of the SD Memory Card is checked when the power is turned ON and periodically while the SD
Memory Card is inserted.
