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 and Groups and Tags.
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.
