[Design Precautions]
WARNING
● When connecting GX Works2 with the CPU module or connecting a personal computer with an
intelligent function module to modify data of a running programmable controller, configure an
interlock circuit in the program to ensure that the entire system will always operate safely.
For other forms of control (such as program modification or operating status change) of a running
programmable controller, read the relevant manuals carefully and ensure that the operation is safe
before proceeding. Especially, when a remote programmable controller is controlled by an external
device, immediate action cannot be taken if a problem occurs in the programmable controller due to
a communication failure. To prevent this, configure an interlock circuit in the program, and determine
corrective actions to be taken between the external device and CPU module in case of a
communication failure.
● For the operating status of each station after a communication failure, refer to Page 140, Section
8.1.7 in this manual. Incorrect output or malfunction due to a communication failure may result in an
accident.
● Do not write any data to the "system area" of the buffer memory in the intelligent function module.
Also, do not use any "use prohibited" signals as an output signal from the CPU module to the
intelligent function module.
Doing so may cause malfunction of the programmable controller system.
● To set a refresh device in the network parameter, select the device Y for the remote output (RY)
refresh device. If a device other than Y, such as M and L, is selected, the CPU module holds the
device status even after its status is changed to STOP.
● If a communication cable is disconnected, the network may be unstable, resulting in a
communication failure of multiple stations. Configure an interlock circuit in the program to ensure
that the entire system will always operate safely even if communications fail.
Failure to do so may result in an accident due to an incorrect output or malfunction.

[Design Precautions]
CAUTION
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the
user's manual for the CPU module used. Failure to do so may result in electric shock, fire,
malfunction, or damage to or deterioration of the product.
● To mount the module, while pressing the module mounting lever in the lower part of the module, fully
insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it
snaps into place. Incorrect mounting may cause malfunction, failure, or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the module
with a screw.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
[Wiring Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
3
[Wiring Precautions]
CAUTION
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove the film during wiring. Remove it for heat
dissipation before system operation.
● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. Pulling the cable connected to the module may
result in malfunction or damage to the module or cable.
● Use 1000BASE-T-compliant Ethernet cables for Ethernet connection. For the maximum station-tostation distance and the overall cable distance, follow the specifications in this manual. If not, normal
data transmission is not guaranteed.
[Startup and Maintenance Precautions]
WARNING
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the module fixing screw. Failure to do so may result in electric shock.
4
[Startup and Maintenance Precautions]
CAUTION
● Before performing online operations (especially, program modification, forced output, and operating
status change) for the running CPU module on another station from GX Works2 over CC-Link IE
Field Network, read relevant manuals carefully and ensure the safety. Improper operation may
damage machines or cause accidents.
● Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
● Tighten the screw within the specified torque range. Undertightening can cause drop of the screw,
short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● After the first use of the product, do not mount/remove the module to/from the base unit more than
50 times (IEC 61131-2 compliant).
Exceeding the limit may cause malfunction.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

1.1 CC-Link IE Field Network
CC-Link IE Field Network is a high-speed and large-capacity open field network that is based on Ethernet technology
(1000BASE-T).
(1) Data communication
High-speed and large-capacity data communication is available between a master station and slave stations on
CC-Link IE Field Network.
(a) Periodic communication (cyclic transmission)
Data is periodically communicated among stations within the same network. ( Page 123, Section 8.1)
20
(b) Irregular communications (transient transmission)
Data is communicated upon request. ( Page 144, Section 8.2)

1000BASE-T
(2) 1Gbps communication speed
1Gbps communication speed allows high-speed communication. Also, the takt time can be reduced due to the
improved performance of communication response.
(3) Use of Ethernet cable
A 1000BASE-T-compliant Ethernet is used for the connection interface. The wiring cost can be reduced because
1000BASE-T-compliant Ethernet cables are commercially available. ( Page 59, Section 5.3)
(4) Flexible wiring for system arrangements
The network can be wired into star topology, line topology, and ring topology. ( Page 49, Section 5.2.1)
For star topology, a 1000BASE-T compliant switching hub can be used. ( Page 60, Section 5.3.2)
Wiring is highly flexible because a network can consist of a combination of star and line topologies. For example,
the control panels can be connected through a star topology and the production lines through a line topology.

1.2 Master/Local Modules
A master/local module is used to connect a MELSEC-Q series programmable controller to CC-Link IE Field Network.
The module works as a master station or a local station on CC-Link IE Field Network.
(1) High-speed periodic communication (cyclic transmission)
Since transmission delay time is short, delay caused during communication does not need to be considered (if the
link scan time of each master/local module is shorter than the scan time of the CPU module).
Command
High speed
Master/local modules can perform cyclic transmissions in combination with the following functions:
( Page 36, Section 3.3)
• Auto transfer of data between the link devices in the master/local module and the devices in the CPU module
• Direct access to the link devices in the master/local module by a program
• Cyclic data assurance in units of 32 bits or per station
• Status setting (hold or clear) of input data from a slave station where a cyclic error has occurred
• Station reservation for future connection, and others

(2) Irregular communications with the programmable controller on another station
(transient transmission)
(a) Reading or writing data
A master/local module can access programmable controllers on other stations by dedicated instructions.
( Page 236, Section 10.1)
Seamless access of programmable controllers on other networks such as Ethernet, CC-Link IE Controller
Network, MELSECNET/H, and MELSECNET/10 is also possible.

(3) Settings and diagnostics by GX Works2
(a) Setting parameters
Parameters for master/local modules can be set using GX Works2. Creating parameter setting programs is not
necessary. ( Page 81, CHAPTER 7)
Parameters for master/local modules can be also set by a program. ( Page 359, Section 10.17)
When set by a program, the parameters of the master station can be changed while the CPU module is
running.

(b) Checking CC-Link IE Field Network status graphically
The CC-Link IE Field Network status can be checked using GX Works2. Error locations, error causes, and
event history are displayed on the window. This allows the system to quickly recover from errors.

can be tested or monitored.
GX Works2 can seamlessly access (test or monitor) systems composed of other networks through CC-Link IE
Field Network. The accessible networks are Ethernet, CC-Link IE Controller Network, MELSECNET/H,
MELSECNET/10, and CC-Link.
Seamless access enables the user to change the access target without modifying the connection between the
personal computer and programmable controller.
