File transfer function
(FTP)
Enables the use of FTP (File
Transfer Protocol) server function,
which transfers files between the
CPU module and external devices.
External devices with a FTP client
function can directly access to the
files in the CPU module.
××××
Predefined protocol
function
Sends and receives packets
predefined by using GX Works2,
enabling easy communications
with external devices (such as
measuring instruments and bar
code readers)
×××× ×
*1
Socket communication
function
Communicates data (using
TCP/UDP) with external devices
connected on the Ethernet
network. The function is executed
by dedicated instructions.

Simple PLC
communication
function
*1*2
Allows data communications
between specified devices at the
specified timing just by doing
simple settings from a
programming tool.
×××× ×
*1
IP address change
function
Changes an IP address of a built-
in Ethernet port by storing it in the
special relay and special register,
not in the built-in Ethernet port
setting parameter.
××××
*1
IP packet transfer
function
Communicates with the following
devices that correspond to IP
address specified via a CC-Link
IE Controller Network module or
CC-Link IE Field Network module,
using a protocol such as the FTP
or HTTP via a built-in Ethernet
port from an Ethernet device such
as a personal computer.
• External devices on the CC-
Link IE Controller Network or
CC-Link IE Field Network
• External devices on the Ethernet
network, which are connected
through the built-in Ethernet ports

Reading/writing device
data from/to the CPU
module on another
station by specifying an
IP address
Reads/writes device data from/to
the CPU module on another
station by using the dedicated
instructions.
×××× ×
*1
SLMP frame send
instruction
Sends MC protocol messages
(QnA-compatible 3E frame and
4E frame) from the CPU module
to external devices connected on
the Ethernet network.
