2.8 Communications with an OMRON PLC (FINS Communications Service)
Using I/O Message Communications with the MP3000 as the Master
2-208
4. Set the connection parameters.
Enter “9600” in the MP3000 Local Port Box.
Enter the following address for the remote device in the Node IP Address Box: 192.168.001.002.
Enter “9600” in the Node Port Box.
Select TCP in the Connect Type Box.
Select OMRON (FINS) in the Protocol Type Box.
Select BIN in the Code Box.
Enter “IW0000” in the Head register number Box as the read data destination.
Enter “200” in the next box as the size of data to read.
Select Data Memory as the I/O memory type in the Head register number box.
Enter “02000” as the first address in the remote device.
Enter “2” in the Node Address Box for the other device.
Enter “00” in the Unit Address Box for the other device.
Select Low in the Data update timing Box as the timing to update I/O data between the CPU Function
Module and 218IFD.
Note: 1. In I/O message communications, a message is transmitted from separate ports if registers are both read
and written. Therefore, the connected remote device must have two connections to receive both mes-
sages.
If communicating with FINS/UDP, select UDP in the Connect Type Box.
2. The network address cannot be set from the MP3000. The network address is always 00 hex. This means
that messages cannot be sent to nodes on another network.
To reference registers in the CPU Unit of the OMRON PLC, enter “00” in the Unit Address Box. “00”
indicates the CPU Unit of the PLC at the specified node address.
3. The data update timing is the timing at which the CPU Function Module and 218IFD exchange data. Com-
munications with the remote device are performed asynchronously. The data update timing therefore does
not necessarily mean that the messages are sent to the remote device.
5. Double-click the Setting Button in the Detail Box.
