Before using this product, please read this manual and the relevant manuals introduced in this manual
carefully and pay full attention to safety to handle the product correctly.
The instructions given in this manual are concerned with this product only. For the safety instructions of the
programmable controller system, please read the user's manual of the CPU module used.
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".
DANGER
CAUTION
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 save this manual to make it accessible when required and always forward it to the end user.
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in medium or slight personal injury or physical damage.
[DESIGN PRECAUTIONS]
DANGER
For each station's operating status in the case of a communication error in the network, refer to this
manual. A malfunction due to a communication error may result in an accident.
To control a running programmable controller (data modification) by connecting GX Developer to a
CPU module or connecting a personal computer to an intelligent function module, create an interlock
circuit on the sequence program so that the entire system will function safely all the time.
Also, before performing any other controls (e.g. program modification, operating status change
(status control)) to the programmable controller, read the manual carefully and ensure the safety.
Especially, in the case of controlling a remotely-located programmable controller from an external
device, a programmable controller side problem could not be resolved immediately due to data
communication failure.
To prevent this, establish corrective procedures for communication failure between the external
device and the programmable controller CPU, as well as creating an interlock circuit on the program.
Laser diodes are used in the optical transceivers of the CC-Link IE controller network.
The class of these laser diodes is Class 1.
A - 1
[DESIGN PRECAUTIONS]
CAUTION
Do not install the control lines and/or communication cables together with the main circuit or power
cables, and also do not bring them close to each other.
Keep a distance of 100mm (3.94 inch) or more between them. Failure to do so may cause a
malfunction due to noise.
[INSTALLATION PRECAUTIONS]
CAUTION
Use the programmable controller in the environment conditions given in the general specifications of
the User's Manual for the CPU module used.
Failure to do so may cause an electric shock, fire, malfunction, or damage to or deterioration of the
product.
While pressing the installation lever located at the bottom of the module, insert the module fixing
projection into the fixing hole in the base unit to mount the module.
Incorrect module mounting may cause a malfunction, failure, or drop of the module.
In an environment of frequent vibrations, secure the module with the screw.
The screw must be tightened within the specified torque range.
If the screw is too loose, it may cause a drop, short circuit, or malfunction.
Excessive tightening may damage the screw and/or the module, resulting in a drop, short circuit or
malfunction.
Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the module.
Failure to do so may damage the module.
Do not directly touch any conductive part or electronic component of the module.
Doing so may cause a malfunction or failure of the module.
[WIRING PRECAUTIONS]
DANGER
Be sure to shut off all phases of the external power supply before installation or wiring.
Failure to do so may result in an electric shock or damage to the product.
A - 2
[WIRING PRECAUTIONS]
CAUTION
Always ground the FG terminal to the protective ground conductor.
Failure to do so may cause a malfunction.
Verify the rated voltage and pin-out, and connect the external power supply cable properly.
Connecting a power supply with a different voltage rating or faulty wiring may cause a fire or failure.
Terminal screws must be tightened with the specified torque.
If a screw is loose, it may cause a short circuit, fire or malfunction.
Be careful to prevent foreign matter such as dust or wire chips from entering the module.
Failure to do so may cause a fire, failure or malfunction.
Be sure to place the communication cables or power cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in damage to the module or
cables, or malfunctions due to poor cable connection.
When disconnecting a communication cable or a power cable from the module, do not pull the cable
part.
For a cable with connectors, hold the connector by hand and disconnect it from the module.
For a cable connected to a terminal block, loosen the terminal block screws and disconnect the
cable from the module.
Pulling a cable that is still connected to the module may cause a malfunction or damage the module
and/or the cable.
A protective film is attached to the module top to prevent foreign matter such as wire chips from
entering the module during wiring.
Do not remove the film during wiring.
Be sure to remove it for heat dissipation before system operation.
[STARTUP/MAINTENANCE PRECAUTIONS]
CAUTION
When performing online operations (especially, program modification, forced output or operating
status change) by accessing a running CPU on another station from GX Developer via CC-Link IE
controller network, read the manual carefully and ensure the safety.
Improper operation will cause mechanical damage or accidents.
Do not disassemble or remodel each of the modules.
Doing so may cause failure, malfunctions, personal injuries and/or a fire.
A - 3
[STARTUP/MAINTENANCE PRECAUTIONS]
CAUTION
When using a wireless communication device such as a mobile phone, keep a distance of 25cm
(9.85 inch) or more from the programmable controller in all directions.
Failure to do so may cause malfunctions.
Be sure to shut off all phases of the external power supply used by the system before mounting or
removing the module.
Not doing so may result in a failure or malfunction of the module.
Do not touch terminals during power-on.
Doing so may cause malfunctions.
Be sure to shut off all phases of the external power supply used by the system before cleaning or
retightening the terminal screw or module mounting screw.
Not doing so may result in a failure or malfunction of the module.
If the screw is too loose, it may cause a drop, short circuit or malfunction.
Excessive tightening may cause damage to the screw and/or module, resulting in a drop, short
circuit or malfunction.
Before handling the module, touch a grounded metal object to discharge the static electricity from
the human body.
Not doing so may cause a failure or malfunction of the module.
Do not install/remove the module to/from the base unit more than 50 times after the first use of the
product. (IEC 61131-2 compliant)
Failure to do so may cause malfunction.

the link register (LW) is 16K points (16384 points, 32KB).
Because the link scan time and transmission delay time are short, applications for
production of a short takt time can be built.

For the Universal model QCPU, the extended link register (W) is useful for
transferring link register (LW) data that exceeds the link register (W) capacity (8K
points).

(g) Cyclic transmission is available only to any specific stations. (Group cyclic
transmission function)
A Universal model QCPU can share cyclic data with stations in the same shared
group.
This function is useful, for example, when sharing data among all stations that
integrates and controls production lines and not sharing the data with stations that
controls other machines.
Also, receiving cyclic data only from any specific stations can reduce the number
of link refresh points, resulting in a shorter link refresh time.

OVERVIEW
(c) When a station disconnected from a network due to a data link error recovers from
the error, the station is automatically reconnected to the network and restarts data
link. (Automatic return function)
This automatic return does not affect data link.

OVERVIEW
(g) The external power can be directly supplied to the CC-Link IE controller network
module with external power supply function. (External power supply function)
Even if a CPU module power goes down in a network, data link will be continued
among normally operating stations without being disrupted at the power-down
station. (Loopback does not occur.)
Data link is also continued between failed stations when power failure has
occurred on CPU modules on multiple stations.
