1.2 Overview of Communication Functions

1.2.1 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)

1.2.2 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. Me ssages in accordance wit h the protocol are
automatically generated by PLC. In the user program, read ing and writin g can be done simply by
specifying the station no. an d memory a ddress an d executi ng SE ND/RECV instru ction s.

 Slave communication is performed when the computer or display connected to PLC has th e

sending right, and sends commands, and PLC returns responses. In slave communication, PLC
responds automatically, so no program concerning com mu nic ation i s necessary on the P LC 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.

 Examples of applications of MEWTOCOL master communication
This is used for connection with a device that supports our PLC's protocol MEWTOCO L.

 Programmable controller FP series
 Displacement sensor HL series
 Eco power meter KW series

 Examples of applications of MEWTOCOL slave communication
This is used for connection with a device that supports our PLC's protocol MEWT OCOL-COM

master communication.
 Programmable displays made by various manufacturers

1.2.3 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 t he 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 instructions.

 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 comm unication 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.

1.2.4 General-Purpose Communication

 Overview of function

 General-purpose communication is used when PLC executes communication in accordan ce

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 instruction.

 Response received from the partner device is temporarily saved in the buffer. Based on the

reception done flag, GPRECV instruction 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.

3.2.3 Wiring Method

 Wiring method

(1) Remove a portion of the wire’s insulation.

(2) Insert wire into terminal hole until it stops. Tighten screw clockwise to fix wire in place.
(The tightening torque: 0.22 to 0.25 N·m (2.3 to 2.5 kgf·cm))

 Precautions on wiring

The following precautions should be observed, to avoid broken or disconnected wire s.

 When removing the wire’s insulation, be careful not to scratch the core wire.
 Do not twist the wires to connect them.
 Do not solder the wires to connect them. The solder may break due to vibration.
 After wiring, make sure stress is not applied to the wire.
 In the terminal block socket construction, if the wire is fastened upon counter-clockwise

rotation of the screw, the connection is faulty. Disconnect the wire, check the terminal hole,
and then re-connect the wire.

3.3 Wiring for CPU Unit (GT Power Supply and COM0 Port)

3.3.1 Handling of GT Power Supply Terminals

 GT power supply terminals can be used as power supply terminals for the GT series of our

programmable displays.

 In accordance with the model to be used, use either 5V DC or 24V DC.

NOTES

 GT power supply terminals (5V DC / 24V DC) are design exclusively for the

GT series of our programmable displays. Do not use the terminals for other
devices.

 GT power supply terminals and COM0 port (RS-232C) are insulated inside.
