This section shows a list of Ethernet module functions.
(1) Basic functions of the Ethernet module
The Ethernet module can perform the communications shown in the table below
via TCP/IP or UDP/IP communication.
Subset of a
compatible 1E Reads/writes PLC data from/to an external device.
frame
Procedure exist Sends/receives arbitrary data between the PLC and the
external device using the fixed buffer of the Ethernet module.
No procedure
Sends/receives data via e-mail.
• Sending/receiving by the PLC
(2) Additional functions of the Ethernet module
The following table lists the additional functions of the Ethernet module that can
be used.
Performs data communication via a router or gateway. (The router
relay function is not a function by which the Ethernet module works as
a router.)
Checks whether or not the external device is working normally after a
connection is established (open processing).
Pairs and then opens a reception connection and a transmission
connection (for fixed buffer).
MELSOFT products (GX Developer, etc.) are connected via TCP/IP
communication. It is also possible to connect multiple MELSOFT
products simultaneously.
(3) Status check of the Ethernet module
Checks that the Ethernet module is working and can communicate normally.
Checks the Ethernet module's sending/receiving function and line
connection status.
Tests the RAM and ROM of the Ethernet module.
When a data communication error occurs, this function stores the error
information (error log), including the message subheader and IP
address of the external device for a maximum of 16 pairs in the buffer
memory.
