1.3 Overview of Communication Functions
1.3.1 PLC Link Functions (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 the connected PLCs.
Among up to 16 PLCs, data can be exchanged with 1,008 link relay points and 128 link
register words.
Applications of PLC Link Functions (MEWNET-W0)
Among our FP series PLC, it can be used for link functions with the following models. It is also
capable of 1:1 communication via RS-232C port.
FP-X0 (L40MR / L60MR)
FP0R (RS485 type)
FPΣ(Using Communication cassette RS-485 type)
FP-X (Using Communication cassette RS-485 type)
FP2 Multi Communication Unit (Using Communication cassette RS-485 type)

1.3 Overview of Communication Functions
1-5
1.3.2 MEWTOCOL Master/Slave Communication
Overview of function
Execute communication using MEWTOCOL-COM, a communication protocol used by our PLC.
In master communication, PLC executes communication by sending commands to devices that
support MEWTOCOL, and receiving responses. Messages in accordance with the protocol are
automatically generated by PLC. In the user program, reading and writing can be done simply by
specifying the station no. and memory address and executing SEND/RECV commands.
Slave communication is performed when the computer or display connected to PLC has the
sending right, and sends commands, and PLC returns responses. In slave communication, PLC
responds automatically, so no program concerning communication is necessary on the PLC side.
The data size that can be sent or received in a single communication is up to 507 words for
register transmission (up to 1,014 words for MEWTOCOL7-COM) and 1 bit for bit transmission.

1.3.3 MODBUS RTU Master/Slave Communication
Overview of function
This is used for communicating with other devices that support the MODBUS RTU protocol.
In master communication, communication is performed when the master unit sends
instructions (command messages) to slave units and the slave unit returns responses
(response messages) according to the instructions. Messages in accordance with the
protocol are automatically generated by PLC. In the user program, reading and writing can
be done simply by specifying the station no. and memory address and executing
SEND/RECV commands.
Slave communication is performed when the higher device connected to PLC has the
sending right, and sends commands, and PLC returns responses. In slave communication,
PLC responds automatically, so no program concerning communication is necessary on the
PLC side.
The data size that can be sent or received in a single communication is up to 127 words for
register transmission and 2,040 bit for bit transmission.

Examples of applications of MODBUS-RTU master communication
This is used for connection with a device that supports the MODBUS-RTU protocol.
Thermoregulator KT series
Devices from other manufacturers that support MODBUS-RTU
Examples of applications of MODBUS-RTU slave communication
This is used when access is made from the higher device using MODBUS-RTU commands.

1.3.4 General-Purpose Communication
Overview of function
General-purpose communication is used when PLC executes communication in accordance
with the protocol of the partner device.
Formulation and sending of command messages to the partner device, and reception
processing of responses from the partner device, are performed by the user program.
Sending/receiving of data with an external device is executed via given operation memory
(e.g. data register).
Data are sent by converting commands in accordance with the partner device as strings into
ASCII text, setting them into a given data register, and executing GPSEND command.
Response received from the partner device is temporarily saved in the buffer. Based on the
reception done flag, GPRECV command is executed. The ASCII strings can be converted
into numerical data, etc. as necessary, by the user program.
The data size that can be sent or received in a single communication is up to 4,096 bytes.
(including control codes)
Applications of general-purpose communication
This is used for connection with devices made by differing manufacturers that have dedicated
communication protocols.
