PLC side settings

Configure the "FX3U-16M". The configuration is done using the FX3U-ENET-L configuration tool.

1.Start the FX3U-ENET-L setting tool

2.Click the "Specify connection" button to confirm that the connection to the FX is established.
c_plc_0156

c_plc_0157

If the connection is successful, the following message will be displayed:
c_plc_0158

3.Click the "Operation Settings" button on the screen to display the Operation Settings screen.
c_plc_0159

4.Configure the settings as follows and click "Finish"
c_plc_0160

setting	Setting contents
Communication data code setting	Binary Code Communication
Initial timing setting	Always waiting for an OPEN (communication possible during STOP)
IP Address Settings	192.168.0.100
Send frame settings	Ethernet (V2.0)
TCP Liveness confirmation settings	Use Ping

5.Press the "Open Settings" button on the screen to display the Open Settings screen.
c_plc_0161

6.Configure the settings as follows and click "Finish"
Set the connection number to 3 or 4.
c_plc_0162

setting	Setting contents
protocol	UDP
Open Method	MC protocol (automatically set)
Survival confirmation	Do not confirm
Local station port number (decimal number)	8192
IP address of the communication partner	192.168.0.1
Port number of communication partner (decimal number)	8193

When setting the port number, set it in decimal. You can also set the port number freely. The port number on the PC side and the PLC side can be the same.

Connections No. 1 and 2 cannot be used because they are reserved for fixed buffer connections. Use only connection No. 3 or 4.

7.After specifying the unit, click "Write" to write the settings to the PLC.
c_plc_0163

If the connection between the FX3U-ENET-L setting tool and the PLC is made via the Ethernet port rather than via the serial/USB port, after writing, turn the power to the PLC (CPU and FX3U-ENET-L) OFF once and then turn it on again.

PC settings

Use the Server application to connect to the PLC for which you have set up communications.

1.Right-click "Application" - "Driver" in the tree and select Add Driver.

2.Select the following units from the displayed driver list and add them:
c_plc_0164

3.Open the properties of the added unit (U01) and click Communication Settings.
c_plc_0165

4.Configure the following in "PC Settings"
c_plc_0801

setting	Setting contents
Computer IP address	192.168.0.1
Computer port number	8193 (specified in decimal)

5.Set the following in "Unit side settings"
c_plc_0116

setting	Setting contents
Unit IP Address	192.168.0.100
Unit Port Number	8192 (specified in decimal)

6.Select "Ping Test" to check if the ping goes through normally.
If you see a message like "Ping test is success～", the test was successful.

7.Select the protocol in "Communication Details"
c_plc_0117

setting	Setting contents
protocol	UDP (recommended)

8.Perform a connection test to check the connection
c_plc_0166

If a message such as "Connection OK" is displayed, the connection is confirmed to be OK.

The CPU monitoring timer can be set in the "Other detailed settings" in the unit's communication settings dialog.

The CPU monitoring timer is the waiting time on the PLC side from receiving a command from the computer until returning a response to that command.

If you are referencing other PLC devices via MELSECNET or CC-Link, be sure to set an appropriate time (if you set the CPU monitoring timer to 0 and the other PLC goes into a state where its power is cut off, Ethernet communication itself will be disabled). For details, refer to the PLC manual.
