Ethernet Communications
Caution
When the communication protocol is MELSEC, the register type for the default read/write is “Word Device Register: D.”
Select
Connect Type
(TCP, for example).
Select
Code
(BIN, for example).
Set
Node Port IP Address
for the other device (MELSEC Q series) to be connected (“192.168.001.002,” for
example).
Set
Port No.
of the other device (MELSEC Q series) to be connected (“10005, 10006,” for example).
Caution
In I/O message communications, since a message is transmitted from each port number for register read/write, a connected
remote device needs the two receive connections for receiving messages.
Set a storage area (
Input Reg
) for data read by the MP2300S (IW0000, for example).
Set
Read Size
of data to be read by the MP2300S (“100” W, for example).
Set a storage area (
Output Reg
) for data written by MP2300S (OW0064, for example).
Set
Write Size
of data written by the MP2300S (“100” W, for example).
Set an I/O data update timing (
Data update timing
) for the CPU and built-in Ethernet (“Low” scan, for exam-
ple).
Data Update Timing
Data update timing indicates when to give and receive data between the CPU and built-in Ethernet. Communication with the
remote device is carried out asynchronously, so note that a message is not necessarily transmitted to the remote device at each
data update timing.
Set the register type and start address (
Read Reg
) of the remote device (MELSEC Q series) read by the
MP2300S (“D00000,” for example).
Set the register type and start address (
Write Reg
) of the remote device (MELSEC Q series) written by the
MP2300S (“D00100,” for example).
Click
OK
.
5.
Click
Yes
in the parameter setting confirmation dialog box.
Caution
Note that when a parameter with the same connection number is already set and you click
Yes
in the parameter setting confirma-
tion dialog, the setting will be overwritten by the parameter configured in the
Message Communication Easy Setting
Window.
