Alive check function
(alive check of an
external device)
Check with Ping ("Use the Ping")
Checks the connection status of an external device by
sending a Ping message (ICMP Echo) to an external
device. Closes the corresponding connection if no
response message is received.
×
Check with KeepAlive ("Use the
KeepAlive")
Checks the connection status of an external device by
sending an ACK message, which notifies an open status of
the connection opened using the TCP protocol to an
external device.
*4
Pairing open
Enables data communications using two connections with
opening of one port, by pairing the receiving connection
with the sending connection.
×
Communication using automatic open UDP port setting
Enables communications without performing open/close
processing after the station, in which an Ethernet module is
mounted, is started up.
×
Remote password check
Prevents unauthorized access to the CPU module by users
in remote locations.
Simultaneous broadcast
Enables simultaneous broadcast to all Ethernet module
mounted stations within the same Ethernet network, when
fixed buffer communications are performed without
procedure on the condition that UDP/IP is used.
*10
Connection to MELSOFT products or GOT
Enables the connection to a MELSOFT product (such as a
programming tool and MX Component) or GOT
Find CPU function
Finds the CPU modules connected to the same hub as GX
Developer, and displays a list.
×
Time setting function (SNTP client)
Collects time information from the time information server
and sets time in the CPU module automatically.
×
User connection
Connection which is used by user during communications
using the MC protocol or the fixed buffer.
Can be used as MELSOFT communication port of system
connection by setting parameters.
Up to 16 connections can be used.
System connection
Auto open UDP port
Connection which is used by the system only.

IP packet transfer function
Communicates data (using FTP or HTTP) through the
built-in Ethernet ports from an Ethernet device (such as a
personal computer) to the following IP-compatible devices
connected via a CC-Link IE Controller Network or CC-Link
IE Field Network module.
• External devices on 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
×
Communications using SLMP
Enables an external device to read/write data from/to the
SLMP-compatible device connected to the shared network
with the Ethernet module.
In addition, enables an external device to read/write data
from/to a device in the CPU module connected to the
Ethernet module.
