resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in medium or slight personal injury or physical damage.
Note that the !CAUTION level may lead to a serious consequence according to the circumstances.
Always follow the instructions of both levels because they are important to personal safety.
Please store this manual in a safe place and make it accessible when required. Always forward it to the
end user.
[Design Precautions]
!DANGER
•For details on the operating status of each station when a communication abnormality occurs in
the data link, see the manual for each data link. Erroneous outputs and malfunctions may lead
to accidents.
Not doing so can cause an accident due to false output or malfunction.
•To prevent malfunctions of the PLC system that may be caused by illegal e-mails from the
outside, take a proper countermeasure (such as virus detection) so that illegal e-mails are not
received by the mail server of this module. (Using an anti-virus program, etc.)
•If it is necessary to ensure the security of the PLC system against unauthorized access from
external devices via the Internet, appropriate measures must be incorporated by the user.
•Then controlling a running PLC (modifying data) by connecting peripheral devices to the CPU
module or connecting a personal computer to the intelligent function module, configure an
interlocking circuit in a sequence program so that the safety of the overall system is always
maintained. Also, before performing other control operations (program modifications and
operation status modifications (status control)) on the running PLC, be sure to read the manual
carefully and thoroughly confirm the safety.
Especially in the above mentioned control operations that are performed from an external device
to a remote PLC, any problems on the PLC side may not be dealt with promptly due to abnormal
data communication. In addition to configuring an interlocking circuit in a sequence program,
determine how the system handles data communication abnormalities, etc. between the
opposite devices and the PLC CPU.

A - 2 A - 2
[Design Precautions]
!DANGER
•Do not write any data in the "system area" of the buffer memory of the intelligent function
module. Also, do not output (turn on) the "use prohibited" signal, which is one of the output
signals from the PLC CPU to the intelligent function module. If data is written to the "system
area" or the "use prohibited" signal is output, there is a risk that the PLC system may
malfunction.
!CAUTION
•Do not bundle the control wires and the communication cables with the main circuit and the
power wires, and do not install them close to each other. They should be installed at least 100
mm (3.94 in.) away from each other. Failure to do so may generate noise that may cause
malfunctions.
•When the status control (remote RUN/STOP, etc) of the PLC CPU is performed from the
external device, select the "Always wait for OPEN" parameter set by an user in advance. (Select
with the initial timing setting in the operational setting.) If "Do not wait for OPEN" is selected the
communication line at remote STOP is closed. The communication line cannot be reopened on
the PLC CPU side after that, and the remote RUN from the external device cannot start either.
[Installation Precautions]
!DANGER
•Use the PLC in an environment that meets the general specifications listed in the user's manual
for the CPU module to use. Using the PLC in any other operating environments may cause
electric shocks, fires or malfunctions, or may damage or degrade the module.
•While pressing the installation lever located at the bottom of module, insert the module fixing tab
into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing
hole as a supporting point.
If the module is not installed properly, it may cause the module to malfunction, fail or fall off.
Secure the module with screws especially when it is used in an environment where constant
vibrations may occur.
•Be sure to tighten the screws using the specified torque. If the screws loose, it may cause the
module to short-circuit, malfunction or fall off. If the screws are tightened excessively, it may
damage the screws and cause the module to short-circuit, malfunction or fall off.
•Before mounting or dismounting the module, make sure to shut off all phases of the external
power supply. Failure to do so may damage the module.
•Do not directly touch the conducting parts and electronic parts of the module.
This may cause the module to malfunction or fail.

A - 3 A - 3
[Wiring Instructions]
!CAUTION
•Use crimp-contact, pressure-displacement or soldering to wire the connectors for external
connections properly using the manufacturer-specified tools.
If the connection is incomplete, it may cause the module to short circuit, catch fire, or
malfunction.
•Do not connect the AUI cable when the power to the station in which the module is loaded is on.
•Make sure to place the communication and power cables to be connected to the module in a
duct or fasten them using a clamp. If the cables are not placed in a duct or fastened with a
clamp, their positions may be unstable or moved, and they may be pulled inadvertently.
This may damage the module and the cables or cause the module to malfunction because of
faulty cable connections.
•Tighten the terminal screws using the specified torque. If the terminal screws are loose, it may
cause the module to short-circuit, malfunction or fall off. If the terminal screws are tightened
excessively, it may damage the screws and cause the module to short-circuit, malfunction or fall
off.
•When disconnecting the communication and power cables from the module, do not pull the
cables by hand. When disconnecting a cable with a connector, hold the connector to the module
by hand and pull it out to remove the cable. When disconnecting a cable connected to a terminal
block, loosen the screws on the terminal block first before removing the cable. If a cable is
pulled while being connected to the module, it may cause the module to malfunction or damage
the module and the cable.
•Be careful not to let any foreign matter such as wire chips get inside the module. They may
cause fire, as well as breakdowns and malfunctions of the module.
•A protective sheet is pasted on the upper part of the module in order to prevent foreign matter
such as wire chips to get inside the module while wiring.
Do not remove this protective sheet during wiring work. However, be sure to remove the
protective sheet before operating the module to allow heat radiation during operation.
•Solder the coaxial cable connectors properly. Incomplete soldering may result in malfunctions.

[Setup and Maintenance Precautions]
!CAUTION
•Never disassemble or modify the module. This may cause breakdowns, malfunctions, injuries or
fire.
•Before mounting or dismounting the module, make sure to shut off all phases of the external
power supply. Failure to do so may cause the module to breakdown or malfunction.
•Do not mount/remove the module onto/from base unit more than 50 times (IEC61131-2-
compliant), after the first use of the product.
Failure to do so may cause the module to malfunction due to poor contact of connector.
•Do not touch the terminals while the power is on. Doing so may cause electric shocks or
malfunctions.
•Before cleaning the module or retightening the terminal screws and the module mounting
screws, make sure to shut off all phases of the external power supply. Failure to do so may
cause the module to breakdown or malfunction. If the screws are loose, it may cause the
module to short-circuit, malfunction or fall off. If the screws are tightened excessively, it may
damage the screws and cause the module to short circuit, malfunction or fall off.
•Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
[Operating Precautions]
!CAUTION
•Please read the user's manual carefully and confirm the safety thoroughly before proceeding to
perform control operations of the PLC (especially, modifications of data, programs and operation
status (status control)) that is running by connecting personal computers, etc. to the intelligent
function module.
Incorrect modifications of data, programs and operating status may cause system malfunctions,
