SAFETY PRECAUTIONS
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle
the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable
controller system, refer to the MELSEC iQ-R Module Configuration Manual.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
[Design Precautions]
WARNING
● Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
(3) All outputs may be turned on if an error occurs in a part, such as an I/O control part, where the
CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety
mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit
example, refer to "General Safety Requirements" in the MELSEC iQ-R Module Configuration
Manual.
(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an
output circuit. Configure an external circuit for monitoring output signals that could cause a
serious accident.
● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
● Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.
● For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.

[Design Precautions]
WARNING
● When connecting an external device with a CPU module or 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,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.
● 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.
● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to
each module. Doing so may cause malfunction of the programmable controller system. For the
"system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the
module used.
● 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.
● To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
[Precautions for using CC-Link IE Controller Network (when optical fiber cables are used)]
● The optical transmitter and receiver of the CC-Link IE Controller Network module use laser diodes
(class 1 in accordance with IEC 60825-1). Do not look directly at a laser beam. Doing so may harm
your eyes.

[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.
● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design circuits so
that the entire system will always operate safely, regardless of the time.
● Do not power off the programmable controller or reset the CPU module while the settings are being
written. Doing so will make the data in the flash ROM undefined. The values need to be set in the
buffer memory and written to the flash ROM again. Doing so also may cause malfunction or failure of
the module.
● When changing the operating status of the CPU module from external devices (such as the remote
RUN/STOP functions), select "Do Not Open by Program" for "Opening Method" of "Module
Parameter". If "Open by Program" is selected, an execution of the remote STOP function causes the
communication line to close. Consequently, the CPU module cannot reopen the line, and external
devices cannot execute the remote RUN function.
[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

Precautions when Ethernet cables are used
Addition of the normal stations
Add/remove normal stations one by one. If multiple slave stations are added/removed at a time, all stations on the network will
be reconnected, and an error may momentarily occur in all the stations.
If a normal station is added to a system having 119 normal stations, the system operates as follows.
■When the firmware version of the control station is "05" or later
Baton pass and data link are not performed in the normal station added after the 120th station, and other stations continues
baton pass and data link.
Even if the disconnected stations are returned to a system having 120 or more normal stations, the stations may not start data
link.
• Whether 120 or more normal stations are connected can be checked using 'Number of connected modules
over occurrence status' (SB0099). Number of connected modules detected by 'Number of connected
modules over occurrence status' (SB0099) is the total of the normal stations which are currently connected
and the disconnected stations (normal stations which were previously connected).
• The number of stations which were previously connected can be cleared by executing the network map
update of the CC-Link IE Controller Network diagnostics. ( MELSEC iQ-R CC-Link IE Controller
Network User's Manual (Application))
• A data link error may be momentarily detected in all the stations since all stations on the network will be
reconnected when executing the network map update.
■When the firmware version of the control station is "04" or earlier
All stations will fail and data link cannot be performed.
Incorrectly configured ring topology

Precautions
Addition of slave stations (including a submaster station)
Add/remove slave stations one by one. If multiple slave stations are added/removed at a time, all stations on the network will
be reconnected, and an error may momentarily occur in all the stations.
If a slave station (including a submaster station) is added to a system having 120 slave stations (including a submaster
station), the system operates as follows.
■When the firmware version of the master station is "05" or later
Baton pass and data link are not performed in the slave stations (including a submaster station) added after the 121st station,
and other stations continues baton pass and data link.
Even if the disconnected stations are returned to a system having 121 or more slave stations (including a submaster station),
the stations may not start data link.
• Whether 121 or more slave stations (including a submaster station) are connected can be checked using
'Number of connected modules over occurrence status' (SB0099). Number of connected modules detected
by 'Number of connected modules over occurrence status' (SB0099) is the total of the slave stations
(including a submaster station) which are currently connected and the disconnected stations (slave stations
which were previously connected).
• The number of stations which were previously connected can be cleared by executing the network map
update of the CC-Link IE Field Network diagnostics. ( MELSEC iQ-R CC-Link IE Field Network User's
Manual (Application))
• A data link error may momentarily occur in all the stations and outputs of the connected slave stations may
turn off since all stations on the network will be reconnected when executing the network map update. Set
output data if needed. ( Page 59 Output hold when a data link error occurs)
■When the firmware version of the master station is "04" or earlier
All stations will fail and data link cannot be performed.
Incorrectly configured ring topology
Do not use a switching hub for ring topology.

Program example of cyclic transmission
The following shows a program example of cyclic transmission.
■Overview of the program example
D0 of the control station (station No.1) is sent to Y50 to Y5F of the normal station (station No.2) through cyclic transmission.
In the program example, an interlock is established with link relay (LB) and cyclic data is sent.
Each number in the figure, from No.1 to No.2, represents a station number.
No.1 is control station and No.2 is normal station.

Program example of error detection in other stations
■Data flow
In the program example, the baton pass status and cyclic transmission status of each station is monitored and some network
errors in other stations are detected in a system configured with three stations.
• When a disconnection or a reconnection of stations is detected, the CC-Link IE Controller Network executes
the line control in all stations to reconstruct the loop.
• During the line control processing, the 'Baton pass status of each station' (SW00A0 to SW00A7) and 'Data
link status of each station' (SW00B0 to SW00B7) are turned on for up to 100ms. (Normally for up to 50ms.)
Therefore, set a value of error monitoring timer to more than 100ms and within the allowable range of your
system.
■Program example
The setting value of error monitoring timer is 200ms.
