1.2 Overview of Communication Functions
1.2.1 PLC Link Function (MEWNET-W0)
Overview of function
•A system can be configured for the PLC link (MEWNET-W0).
•Exclusive internal relays “link relays (L)” and data registers “link registers (LD)” are shared
between connected PLCs.
•Data of link relays (1024 points) and link registers (128 words) can be exchanged between
max. 16 PLC units.
Purpose of PLC link function (MEWNET-W0)
This is used when using the following models and link functions of Panasonic FP series PLCs.
1:1 communication is also possible via RS-232C port.
•FP-X0 (L40MR / L60MR)
•FP0R (RS-485 type)
•FP0H (communication cassette RS-485 type is used)

1.2.2 MEWTOCOL Master / Slave Communication
Overview of function
•Communication is performed using a communication protocol “MEWTOCOL-COM” used by
Panasonic PLC.
•Master communication is performed by PLC sending commands to, and receiving responses
from, devices that support MEWTOCOL. Data can be read and written by specifying unit
numbers and memory addresses and executing F145 (SEND) / F146 (RECV) instructions in
a user program, because PLC automatically creates messages according to the protocol.
•A computer or display connected to PLC has the transmission right in slave communication.
Slave communication is performed when the device sends a command, and PLC returns a
response. In slave communication, no communication program is required on the PLC side,
because PLC automatically returns a response.
•The data size that can be sent or received at a time is a maximum of 507 words for register
transmission, 509 words for register reception, and 1 bit for bit transmission or reception.
Master function
Slave function
Purpose of MEWTOCOL master communication (example)
This is used for connection with devices that support MEWTOCOL (Panasonic PLC protocol).
•Programmable controller FP series
•Displacement sensor HL series
•Eco-power meter KW series
Purpose of MEWTOCOL slave communication (example)
This is used for connection with devices that support MEWTOCOL-COM master
communication (Panasonic PLC protocol).
•Programmable displays from other manufacturers

1.2.3 MODBUS RTU Master / Slave Communication
Overview of function
•Used for communication with other devices that support the MODBUS RTU protocol.
•Master communication is performed when the master unit sends commands to slave units,
and the slave unit returns responses (response messages) according to the instructions.
Data can be read and written between PLC and external devices by specifying unit numbers
and memory addresses and executing F145 (SEND) / F146 (RECV) instructions in a user
program, because PLC automatically creates messages according to the protocol.
•A higher device connected to PLC has the transmission right in slave communication. Slave
communication is performed when the device sends a command, and PLC returns a
response. In slave communication, no communication program is required on the PLC side,
because PLC automatically returns a response.
•The data size that can be sent or received at a time is a maximum of 127 words for register
transmission, and 2,040 bits for bit transmission.
Master function
Slave function
Purpose of MODBUS-RTU master communication (example)
Used for connection with devices that support the MODBUS-RTU protocol.
•Temperature regulator KT series
•Devices that support MODBUS-RTU from other manufacturers
Purpose of MODBUS-RTU slave communication (example)
Used for access from a higher device using MODBUS-RTU commands.

1.2 Overview of Communication Functions
1-7
1.2.4 General-Purpose Communication
Overview of function
•General-purpose communication is used when PLC performs communication in accordance
with the protocol of the connected device.
•A user program should process the creation and transmission of command messages to
connected devices, and the reception of responses therefrom. Data transmission / reception
with external devices is handled through data registers and other given operation memories.
•For transmission, a command aligned to a connected device is ASCII converted into a string,
and set to a given data register. The F159 (MTRN) instruction is executed to send a
command.
•For reception, a response received from a connected device is temporarily stored in the
buffer. The F159 (MTRN) instruction is executed to receive a response. The received ASCII
string data is converted into numerical data, etc. based on a user program.
•The maximum data that can be sent at a time is 2,048 bytes (including control codes). The
maximum data that can be received at a time is 4,096 bytes (including control codes).
Purpose of general-purpose communication
Used for connection with devices from other manufacturers that have specific communication
protocols.
