Existence check
of external device
(Existence check
function)
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
Communication using pairing open method
Pairs the receiving and sending connections and opens
as one connection. (For communication using the fixed
buffer.)
Communication using automatic open UDP
port setting
Enables communication after the station in which an
Ethernet module is mounted has been powered ON.
(Open/close processing for communication by a
sequence program is not required.)
Remote password check
Prevents unauthorized access to the CPU module by
users in remote locations.
Simultaneous broadcast
Sends/receives data for all external devices on the same
Ethernet where the Ethernet module is mounted in data
communication using the UDP/IP protocol.
MELSOFT product
*8
(such as GX
Developer) and/or GOT connection
Connects a MELSOFT product and/or GOT using the
TCP/IP or UDP/IP protocol. Multiple MELSOFT products
and/or GOTs can be connected simultaneously.
Find CPU function
Finds the CPU modules connected to the same hub as
GX Developer, and displays a list.
Time setting function
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.
