# Panasonic Mewtocol

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

For the generic steps, see [Create a Southbound Driver](../south-devices.md) and [Groups and Tags](../../groups-tags/groups-tags.md).

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

## Add Driver

On **Data Collection → South Devices**, click **Add Device**.

- Name: The name of this device node.
- Driver: Select the **Panasonic Mewtocol** driver.

## Connection Parameters

Click the driver card to open the **Device Configuration** page and fill in:

|   Parameter     |  Description                      |
| -------- | -------------------------- |
| **PLC IP Address** |  Target PLC IPv4 address         |
| **PLC Port** | Target PLC IPv4 address, Default 2000 |
| **PLC Station** | Target PLC station, Default 1      |
| **Timeout (ms)** | Target PLC read timeout |

## Tag Configuration

The data types and address formats supported by this driver are listed below.

### Data Types

* INT16
* UINT16
* INT32
* UINT32
* INT64
* UINT64
* FLOAT
* DOUBLE
* BIT
* STRING

### Address format

> AREA ADDRESS\[.BIT]\[.LEN\[H]\[L]]

#### .BIT
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].

#### .LEN\[H]\[L]
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**.

#### PLC Area

| Area | DATA TYPE | ATTRIBUTE  |  REMARK                          |
| ---- | --------- | ---------- | -------------------------------- |
| X    | uint16, uint32, uint64, bit | read/write | External input        |
| Y    | uint16, uint32, uint64, bit | read/write | External output        |
| R    | uint16, uint32, uint64, bit | read/write | Internal relay      |
| T    | uint16, uint32, uint64, bit | read/write | Timer       |
| C    | uint16, uint32, uint64, bit | read/write | Counter           |
| L    | uint16, uint32, uint64, bit | read/write | Link relay       |
| DT   | all | read/write (bit type read-only) | Data register DT   |
| LD   | all | read/write (bit type read-only) | Link data register LD    |
| FL   | all | read/write (bit type read-only) | File register FL     |
| S    | -- | -- | Timer/counter set value area SV     |
| K    | -- | -- | Timer/counter elapsed value area EV     |
| IX   | all   | read/write (bit type read-only) | Index register IX   |
| IY   | all   | read/write (bit type read-only) | Index register IY  |
| ID   | all   | read/write (bit type read-only) | Index register ID  |
