1.3 Overview of Communication Functions
1.3.1 MEWTOCOL-DAT Master/Slave Communication
(Binary Communication)
Overview of function
•Execute communication using MEWTOCOL-DAT, a communication protocol usd by our PLC.
•One of the PLC has the sending right, and executes communication by sending commands
to PLCs that support MEWTOCOL-DAT, and receiving responses.
•The slave-side PLC responds automatically, so no program concerning communication is
necessary.
•Also on the master-side PLC, messages in accordance with the protocol are automatically
generated by PLC. In the user program, reading and writing can be done between PLCs
simply by specifying the station no. and memory address and executing SEND/RECV
commands.
•This is suitable for sending/receiving data between PLCs, because the data size that can be
transmitted in a single communication is larger, and the transmission format is simpler and
shorter, than the MEWTOCOL-COM communication (ASCII communication).
•The data size that can be sent or received in a single communication is up to 2038 words for
register transmission and 1 bit for bit transmission.
(Note) In the case of connection with our PLC FP2 ET-LAN unit, the maximum size is 1020 words.

KEY POINTS
•When MEWTOCOL-DAT master/slave communication is used, select
"TCP/IP" for the communication protocol in order to guarantee the reliability
of communication.

1.3.2 MEWTOCOL-COM Master/Slave Communication
(ASCII Communication)
Overview of function
• Execute communication using MEWTOCOL-COM, a communication protocol used by our PLC.
•One of the device has the sending right, and executes communication by sending
commands to devices that support MEWTOCOL-COM, and receiving responses.
•The slave-side PLC responds automatically, so no program concerning communication is
necessary.
•Also on the master-side PLC, 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.
•Because MEWTOCOL-COM communication is on an ASCII basis, it is suitable for
sending/receiving text data.
•The data size that can be sent or received in a single communication is up to 507 words for
register transmission and 1 bit for bit transmission.

Communication Functions of CPU Unit
1.3.3 MODBUS TCP Master/Slave Communication
Overview of function
•This is used for communicating with other devices that support the MODBUS TCP 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 2040 bit for bit transmission.

1.3 Overview of Communication Functions
1.3.4 General-Purpose Communication
Overview of function
•General-purpose communication is used when PLC executes communication in accordance
with the command specifications 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 setting message/data in a given data register in accordance with the
partner device, and executing GPSEND command.
•Data received from the partner device are temporarily saved in the buffer. Based on the
reception done flag, GPRECV command is executed and the received data are copied into a
given operation memory. The received data 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 16,372 bytes
per connection.
(Note 1) When a dedicated header is not attached, the size is up to 16,384 bytes.
(Note 2) In the case of connection with our PLC FP2 ET-LAN unit, the maximum size is 8,192 bytes.

1.4 Terms
The following terms are used for settings on the software for connecting the FP7 CPU unit to
Ethernet LAN, and in the Users Manuals.
Server connection and client connection
•These indicate methods for connecting a virtual communication line between FP7 and an
external device.
•"Server connection" refers to a method to wait for connection from another client.
•"Client connection" refers to a method to connect a virtual communication line from the FP7
CPU unit to another external device port. Even if connection fails, repeated connection
attempts are made at a specified interval.
Master communication and slave communication
•These indicate methods for actually sending/receiving messages and data between FP7 and
an external device.
•In master communication, PLC sends commands and receives responses.
•In slave communication, commands are received from an external device, and responses
are returned.
•In a system using FP7, whether server connection or client connection is selected, once
connection is opened and a virtual communication line is connected, commands and
responses can be sent and received from both sides.

Installation and Wiring

Installation and Wiring
2.1 Installation Environment and Wiring for LAN Ports
2.1.1 Before Installation and Wiring
Noise resistance of Ethernet
The Ethernet is a network used in offices and buildings, where there is comparatively little
noise. It does not have a higher resistance to noise than ordinary FA application networks.
Caution is required when installing the hub, and when laying cables.
2.1.2 Installation Environment and Noise Control Measures
Measures that can be taken in the installation environm ent
•The CPU unit, transceiver, hub, and communication cables should be installed as far as
possible from high-voltage wires, high-voltage equipment, power lines, power equipment,
equipment that generates strong breaker surges, and the wiring for any of this equipment. At
least 100 mm of clearance should be allowed when installing the equipment.
•When a device must be installed or a cable must be laid near a noise-generating device for
special reasons, take measures such as:
• install a programmable controller and a hub within a metal panel,
• laying a communication cable inside a metal duct,
• attaching a ferrite core near the CPU unit on the communication cable,
etc.
•An alternative measure is to use an optical transceiver close to the noise-generating section
of the equipment and install an optical fiber to keep the noise from affecting nearby
equipment. (This is also effective as a lightning shield for outdoor wiring.)
•Metal panels and metal ducts should be grounded at a grounding resistance of 100 Ω or less.
Also, metal panels and metal ducts should be insulated so that they do not come in contact
with communication devices or cables.
