Files in the local station Q/LCPU to which the Ethernet module is installed can be read
and written from external device using the Ethernet module file transfer function.
In this chapter, how to use (command) the Ethernet module FTP function from an
external device (personal computer, workstations, etc.) is explained.
POINT
The access destination of files handled using the file transfer function is the local
station Q/LCPU in the station to which the Ethernet module is connected.
Specify an access target CPU if the local station QCPU is included in a multiple
CPU system.
The file transfer functions (hereinafter called FTP server) of the Ethernet module to
read/write the files in the Q/LCPU on the external device side are explained.
The Ethernet module supports the FTP (File Transfer Protocol) server function, which
uses the protocol to transfer files between external devices. It functions as the file
server for the files in the Q/LCPU.
The FTP commands are used to direct data transfers in file units.
The external device with the FTP client functions, can easily access (read/write) the
user-created files in the Q/LCPU directly using the Ethernet module FTP server
functions.
1) Reading a file from the Q/LCPU (download)
Reading function for storing the Q/LCPU files in the external device.
2) Writing a file to the Q/LCPU (upload)
Writing function for registering the file in the external device to the Q/LCPU.
3) Scanning Q/LCPU files
Scanning function for checking the files registered in the Q/LCPU, from the external
device.
With these Ethernet module FTP server functions, all user files in the Q/LCPU
(such as parameters, sequence programs, and data files) can be accessed
using the FTP commands from the external device.
