Precautions for using the MELSEC-Q series Ethernet interface
module
[Design Precautions]
!WARNING
For the operating status of each station after a communication failure, refer to relevant manuals
for the network. Erroneous outputs and malfunctions may lead to accidents.
Not doing so can cause an accident due to false output or malfunction.
To prevent the malfunction of the programmable controller system due to harmful e-mails, take
preventive measures (such as antivirus measures) so that the mail server for this module does
not receive harmful e-mails.
To maintain the safety of the programmable controller system against unauthorized access from
external devices via the Internet, take appropriate measures.
When connecting a peripheral with the CPU module or connecting an external device, such as 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.
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 programmable
controller CPU to the intelligent function module.
Doing so may cause malfunction of the programmable controller system.

A - 3 A - 3
[Design Precautions]
!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 changing the operating status of the programmable controller CPU (such as remote
RUN/STOP) from the external device, select "Always wait for OPEN (Communication possible
at STOP time)" for the "Initial timing" setting in the network parameter. The communication line
will be closed when "Do not wait for OPEN (Communications impossible at STOP time)" is
selected and the remote STOP is executed from the external device. Consequently, the
programmable controller CPU cannot reopen the communication line, and the external device
cannot execute the remote RUN.
