communication error.
Use the communication status information, and configure an interlock circuit in the sequence
program so that the system will operate safely.
Incorrect outputs and incorrect operations can lead to accidents.
(1) All points of the general-purpose input from this module will turn OFF.
(2) All points of the general-purpose output from this module will turn OFF.
The input/output may turn ON or OFF depending on the module trouble.
Provide a circuit that externally monitors input/output signals that could lead to serious trouble.

CAUTION
Do not bind the control wire or communication cable with the main circuit or power wire, or
place the control wire near these.
Separate by at least 100mm or more.
Failure to observe this could lead to malfunctions caused by noise.
Always connect the master module and CC-Link dedicated cable at the data link terminal block.

[Mounting Instructions]
!
CAUTION
Use this module within the general specification environment described in the manual.
Use in an environment outside the general specification range could lead to electric shocks,
fires, malfunctioning, product damage or deterioration.
Always connect the crimp, press-fit or solder the connector wire connections with the maker-
designated tools, and securely connect the connector to the module.
An incomplete connection could lead to short-circuits or malfunctioning.
Do not directly touch the conductive section of the module.
Failure to observe this could lead to module malfunctioning or trouble.
Securely fix the module with the DIN rail or installation screw. Tighten the installation screw
within the designated torque range.
A loose screw could lead to dropping, short-circuiting or malfunctioning.
If the screw is too tight, dropping or short-circuiting could occur due to screw damage.
Securely mount the connector of each connection cable to the mounting section.
An incomplete connection could lead to malfunctioning caused by an incorrect contact.

[Wiring Instructions]
!
CAUTION
Before starting installation or wiring work, be sure to shut off all phases of external power supply
used by the system.
Failure to shut off all phases could lead to electric shocks, product damage or malfunctioning.
Always install the terminal covers enclosed with the product before turning ON the power or
operating the product after installation or wiring work.
Failure to install the terminal cover could lead to electric shocks.
Always ground the FG terminal with Class D grounding (Class 3 grounding) dedicated of the
programmable controller.
Failure to do so could lead to malfunctioning.
Always confirm the product's rated voltage and terminal layout before wiring the module.
Connecting with a power supply other than the rated power supply, or incorrect wiring could
lead to fires or trouble.
Tighten the terminal screws within the specified torque range.
A loose terminal screw could lead to short-circuiting or malfunctioning.
If the terminal screw is too tight, dropping or short-circuiting could occur due to screw damage.
Make sure that foreign matter, such as cutting chips or wire scraps, do not enter the module.
Failure to observe this could lead to fires, trouble or malfunctioning.
The communication cables and power supply cable connected to the module must be placed in
a conduit or fixed with a clamp.
If the cable is not placed in a conduit or fixed with a clamp, the module or cable could be
damaged by the cable variation, movement or unintentional pulling leading to malfunctioning
caused by an improper cable connection.
Do not install the control lines together with the communication cables, or bring them close to
each other. Failure to do so may cause malfunctions due to noise.
Do not remove the communication cable or power supply cable connected to the module by
pulling on the cable section.
If the cable has a connector, hold the connector at the section connected to the module, and
remove.
If the cable does not have a connector, loosen the screws at the section connected to the
module, and remove.
Pulling on the cable while connected to the module could lead to module or cable damage, or
malfunctioning caused by an improper cable connection.

[Startup/Maintenance Instructions]
!
CAUTION
When power is ON, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
Before cleaning or tightening the terminal screws and module mounting screws, be sure to shut
off all phases of external power supply used by the system.
Failure to shut off all phases could lead to module trouble or malfunctioning.
Do not touch the connector inside the lid at the front of the module.
Failure to observe this could lead to module trouble or malfunctioning.
Never disassemble or modify the module.
Failure to observe this could lead to trouble, malfunctioning, injuries or fires.
Do not drop or apply any strong impact to the module. Doing so may damage the module.
Before installing or removing the module on the panel, be sure to shut off all phases of external
power supply used by the system.
Failure to shut off all phases could lead to module trouble or malfunctioning.
Do not install/remove the terminal block more than 50 times after the first use of the product.

(1) Easy communication by using the buffer memory automatic update
function.
This function automatically updates the buffer memory between the R2 and
master station at the timing set in R2.
With this, a program to read and write between the R2 and master station can be
eliminated. As the data can be read and written with just the FROM/TO
command, the program is simplified.
(This can be used with all CPUs.)

(2) Addition of frame during data transmission/reception with external
device
By adding a frame to the head and end, a statement format matching the
specifications of the external device, such as the barcode reader or ID controller,
can be created and communicated.
The frames include those that are set as the default, and the frames that can be
randomly created by the user (user registration frame).
A random frame can be added!

Non-procedural data transmission/reception with external

Automatically updates the buffer memory between the R2
and master station at the update timing set in each area of
the R2 buffer memory.
Adds a frame registered for R2 at the head and end of the
transmission data when transmitting data.
Automatically transmits data to the external device when the
user-designated transmission conditions (changes in RX, RY,
RW and status) are established.
After transmission request is issued from the master station
to R2, forcibly cancels the transmission before R2 completes
transmission to external device.
Forcibly completes the reception when reception data from
external device has not reached the reception complete data
size, etc., and reads out the currently received data.
Stops/resumes transmission of data from external device
according to open space in R2 OS reception area.
Stops/resumes transmission of data from R2 according to
requests from external device.
Carries out ASCII-BIN conversion on the
transmitted/received data.
Assigns master station remote register (RW) and R2 side
area to be automatically updated in the buffer memory.
Clears the received data stored in the R2 OS reception area.
Registers a setting value for the R2 buffer memory's specific
application area in the EEPROM, or returns the value
registered in the EEPROM to the R2 default value.
The value for the R2 buffer memory registered in the
EEPROM (including the setting values changed by the user)
is used as an initial value at the time of the R2 startup.
