Mitsubishi FX

The Mitsubishi FX plug-in is used to access Mitsubishi's FX0, FX2, FX3 and other PLC series via the FX programming port.

Add Device

Go to Configuration -> South Devices, then click Add Device to add the driver. Configure the following settings in the popup dialog box.

  • Name: The name of this device node.
  • Plugin: Select the Mitsubishi FX plugin.

Device Configuration

After clicking Create, you will be redirected to the Device Configuration page, where we will set up the parameters required for Neuron to establish a connection with the northbound application. You can also click the device configuration icon on the southbound device card to enter the Device Configuration interface.

Connection TimeoutConnection timeout, default is 3000 milliseconds
Send IntervalCommand transmission interval, default 20 ms
Serial DeviceSerial device path
Stop BitsStop bits, default is 1
ParityParity, default is even
Baud RateBaud rate, default is 9600
Data BitsData Bits, default is 7

Configure Data Groups and Tags

After the plug-in is added and configured, the next step is to establish communication between your device and Neuron by adding groups and tags to the Southbound driver.

Once device configuration is completed, navigate to the South Devices page. Click on the device card or device row to access the Group List page. Here, you can create a new group by clicking on Create, then specifying the group name and data collection interval.

Upon successfully creating a group, click on its name to proceed to the Tag List page. This page allows you to add device tags for data collection. You'll need to provide information such as the tag address, attributes, and data type.

For information on general configuration items, see Connect to Southbound Devices. The subsequent section will concentrate on configurations specific to the driver.
