4. Click the Easy setting Button.
5. Set the connection parameters.
Enter "10005" and "10006" in the Port No. Box for the MP-series Controller.
Select MELSEC (A-compatible 1E) in the Communication Protocol Type Box, and then click
the Default Button.
Note: If you are using the MELSEC (A-compatible 1E) communications protocol, the read and write register
type will be set to D (word device) registers by default.
Select TCP in the Connect Type Box.
Select BIN in the Code Box.
Enter the following address in the Node Port IP Address Boxes for the other device:
192.168.001.002.
Enter “10005” and “10006” in the Port No. Boxes for the other devices.
Note: In I/O message communications, a message is transmitted from each port for which a register read/write
is initiated. Therefore, for this example, the connected remote device must support a message reception
function to receive two messages.
Enter “IW0000” in the Input Reg Box as the read data destination.
Enter “100” in the Read Size Box as the size of data to read.
Enter “OW0064” in the Output Reg Box as the write data destination.
Enter “100” in the Write Size Box as the size of data to write.
Select Low in the Data update timing Box as the timing to update input and output data between the
CPU Function Module and 218FD.
Note: The data update timing is the timing at which the CPU Function Module and 218IFD exchange data.
Communications with the remote device are performed asynchronously. The data update timing there-
fore does not necessarily mean that the messages are sent to the remote device.
Enter “D00000” in the Read Reg Box as the register type and first address to read from on the remote
device.
Enter “D00100” in the Write Reg Box as the register type and first address to write to on the remote
device.
