Mitsubishi 1E

Mitsubishi 1E is a part of Mitsubishi Electric's PLC series that leverages the MELSEC Communication protocol for efficient and reliable data exchange in diverse industrial automation applications.

Neuron's a1e plug-in is used to access Mitsubishi's A series, FX3U, FX3G, iQ-F series PLCs via Ethernet, iQ-F requires a specific firmware version.

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 1E 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.

Transport ModeUse TCP mode or UDP mode
PLC IP AddressTarget PLC IPv4 address
PLC PortTarget PLC IPv4 address, Default 2000
UDP Source PortTarget device port number, available when UDP mode is enabled, default is 52001

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.

It can only be used in non-bit type area, which means to read the specified bit of the specified address, and the binary bit index range is [0, 15].

AddressData TypeDescription
D20.0bitD area, address is 20, bit 0
D20.2bitD area, address is 20, bit 2


When the data type is string, .LEN indicates the length of the string; H and L can be optional to indicate two byte orders, the default is H byte order.
