Panasonic Mewtocol

Mewtocol is a Panasonic-developed protocol enabling data exchange between its PLC devices and various others, such as computers and HMI devices

The Mewtocol plugin is used to access Panasonic's FP-XH, FP0H series PLCs via Ethernet.

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 Panasonic Mewtocol 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.

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.

Data Types

  • INT16
  • UINT16
  • INT32
  • UINT32
  • INT64
  • UINT64
  • BIT

Address format



Only available for non-bit type area, which means reading the specified binary bit of the specified address, the binary bit index interval is [0, 15].


When the data type is string type, .LEN indicates the length of the string; you can optionally fill in H and L to indicate two-byte orders, and the default is the byte order of H.
