[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 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.
●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.

[Design Precautions]
[Design Precautions]
WARNING
●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. Incorrect output or malfunction due to a
communication failure may result in an accident.
●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 C Controller modules]
●In the refresh parameter setting, 'Y' cannot be specified for a link output (LY) refresh device or a
remote output (RY) refresh device. Therefore, C Controller module holds the device status as is even
after the module status is changed to STOP.
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 OFF and ON.
Therefore, use a module that has a sufficient current rating.
●After the power is turned OFF and ON or the CPU module 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 turn the power OFF 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 may cause malfunction or failure of the module.
●When changing the operating status of the CPU module from external devices (such as remote RUN/
STOP functions), select "Do Not Open in Program" for "Open Method Setting" in the module
parameters. If "Open in Program" is selected, an execution of remote STOP causes the
communication line to close. Consequently, the CPU module cannot reopen the communication line,
and the external device cannot execute the remote RUN.
