overview

This is an example of Ethernet connection settings with the iQ-F series. Since the iQ-F FX5 has a built-in Ethernet port attached to the CPU, this connection example uses this built-in port to connect. Note that the iQ-F series cannot be configured with GX-Developer, so GX-Works3 is used.

PLC side settings

Configure "FX5U". The settings are done using GX-Works3 etc.

1.Start GX- Works3 and create a new project.

2.Open the menu "Online" - "Connection Destination" and confirm that you can communicate with PLC.

3.Double-click "Parameters" - "Connected CPU name (FX5UCPU in this case)" - "Unit parameters" - "Ethernet port" in the navigation tree and set the parameters as follows:
c_plc_0138

setting	Setting contents
IP address	192.168.0.100
Subnet mask	255.255.255.0 (set according to your environment)
Default Gateway	192.168.0.200 (set according to your environment)
Communication data code	binary

4.Select "Connection configuration settings for other device" to display the Ethernet configuration screen.
c_plc_0128

5.Add SLMP as a connected device on the Ethernet configuration screen
Select "SLMP connected device" from the unit list and add the device by dragging and dropping it onto the configuration screen.
c_plc_0129

6.Once the "SLMP connected device" has been added, perform the following settings.
c_plc_0139

setting	Setting contents
protocol	UDP
Port number	8192 (specified in decimal)
Sensor device-IP address	192.168.0.1 (Set the IP address of the computer)

When configuring the conventional Q Series etc. with GX-Developer, the port number had to be set in hexadecimal. However, when configuring the iQ-F Series CPU with GX-Works3, please note that the port number must be specified in decimal.

7.Click "Apply settings and close" in the menu to apply the settings and close the screen.
c_plc_0131

8.Write the parameters to the PLC by selecting "Online" - "Write to PLC" from the menu.
c_plc_0133

After setting the parameters, you must turn off the power to the PLC once to reflect the settings. Although a remote reset may be possible from the tool, we recommend turning off the power once to ensure that the settings are reflected.

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:
If you want to communicate using the ASCII protocol, select the ASCII protocol.
c_plc_0140

3.Open the properties of the added unit (U01) and click Communication Settings.
c_plc_0800

4.Configure the following in "PC Settings"
c_plc_0123

setting	Setting contents
Computer IP address	192.168.0.1
Computer port number	Automatic

For models that directly connect to the Ethernet port, you cannot specify the port number of the connection destination, so the port number on the PC side is "Automatic".

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_0118

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.
