SAFETY PRECAUTIONS
(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.
In this manual, the safety precautions are classified into two levels: "
DANGER" and "
CAUTION".
DANGER
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 medium or slight personal injury or physical damage.
Under some circumstances, failure to observe the precautions given under "
CAUTION" may lead to
serious consequences.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
DANGER
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) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and
protective interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) The programmable controller stops its operation upon detection of the following status, and the
output status of the system will be as shown below.
Status
Output
Overcurrent or overvoltage protection of the power supply module
is activated.
All outputs are turned off.
The CPU module detects an error such as a watchdog timer error
by the self-diagnostic function.
All outputs are held or turned off according to
the parameter setting.
All outputs may turn on when an error occurs in the part, such as 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 Chapter 10 LOADING AND INSTALLATION in the QCPU User's Manual
(Hardware Design, Maintenance and Inspection).
(3) Outputs may remain on or off due to a failure of an output module relay or transistor. Configure
an external circuit for monitoring output signals that could cause a serious accident.
A-1
[Design Precautions]
DANGER
In an output module, 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 relevant manuals for
the network.
Incorrect output or malfunction due to a communication failure may result in an accident.
When changing data of the running programmable controller from a peripheral connected to the
CPU module or from a personal computer connected to an intelligent function module, configure an
interlock circuit in the sequence program to ensure that the entire system will always operate safely.
For program modification and operating status change, read relevant manuals carefully and ensure
the safety before operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure.
To prevent this, configure an interlock circuit in the sequence program, and determine corrective
actions to be taken between the external device and CPU module in case of a communication
failure.
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.
When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a
large current (approximately ten times greater than normal) may flow when the output is turned from
off to on.
Take measures such as replacing the module with one having a sufficient current rating.
A-2
[Installation Precautions]
CAUTION
Use the programmable controller in an environment that meets the general specifications in the
QCPU User's Manual (Hardware Design, Maintenance and Inspection).
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the
product.

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 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.
When using an extension cable, connect it to the extension cable connector of the base unit
securely.
Check the connection for looseness.
Poor contact may cause incorrect input or output.
When using a memory card, fully insert it into the memory card slot.
Check that it is inserted completely.
Poor contact may cause malfunction.
Shut off the external power supply for the system in all phases before mounting or removing the
module. Failure to do so may result in damage to the product.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in
the system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module has its
predetermined replacement procedure.
For details, refer to the relevant sections in the QCPU User's Manual (Hardware Design,
Maintenance and Inspection) and in the manual for the corresponding module.
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
When using a Motion CPU module and modules designed for motion control, check that the
combinations of these modules are correct before applying power.
The modules may be damaged if the combination is incorrect.
For details, refer to the user's manual for the Motion CPU module.
A-3
[Wiring Precautions]
DANGER

3.1.2 Setting on GX Developer side
• CPU modules connected to a cascade connected hub are also found and displayed in the list.
• CPU modules connected via a router cannot be found.
• CPU modules connected via wireless LAN may not be found since the Ethernet communication does not stabilize
due to lost packets.
• If CPU modules with same IP address are found in the list, re-examine the parameter settings of the CPU IP
address. If communication is performed with the situation left as is, a communication error occurs.
• CPU modules may not be found if service processing load on CPU modules is heavy.
In that case, extend the response waiting time in the Find CPU (Built-in Ethernet port) screen as shown above, or
extend the service processing time in the PLC parameter dialog box.
• Select the checkbox as shown in Figure 3.10 in the Built-in Ethernet port tab of the PLC parameter dialog box so
that CPU modules to be searched do not respond on the network.
3.1.3 Precautions
The following are the precautions must be taken when connecting the Built-in Ethernet port QCPU with GX Developer
or GOT.
(1) Existence check using the KeepAlive function
When the protocol is set to "TCP", existence check using the KeepAlive function is performed.
The CPU module sends an existence check message five seconds after the last message from the external
device is received and waits to see whether a response from the external device is received.
If there is no response, the CPU module keeps sending an existence check message in five-second intervals.
When a response has not been confirmed within 45 seconds, the connection is disconnected, considering that no
external device exists.
The connection may be disconnected if the external device does not support the TCP KeepAlive function
(response to ACK messages for KeepAlive).
(2) Number of connections exceeding setting range
Establish connections within the number of protocols set for open settings of PLC parameter.
If TCP connections exceeding the set number of connections are made with a personal computer, the status of
some applications may change as described below.
• The status of application may change into the wait status, making the application inoperable.
• The time period causing a time-out error may increase.
(3) Retransmission processing in TCP connection
In TCP connection, if no ACK response message for TCP protocol is received from the external device,
retransmission processing is performed.
Resend processing is performed six times, 0.3, 0.6, 1.2, 2.4, 4.8, and 9.6 seconds after the first message.
If there is no ACK response within a period of 19.2 seconds after the last message is resent, the connection is
disconnected, considering that the external device is not operating normally.
(The connection is disconnected within the total period of 38.1 seconds.)

(3) Access range
• Only connected CPU module can be accessed.
Accessing a CPU module not connected results in an error.
• In a multiple CPU system, other CPU modules not connected to Ethernet cannot be accessed.
• Accessing a CPU module on another station in CC-Link IE controller network, MELSECNET/H, Ethernet or
CC-Link via a connected CPU module is not possible.
(4) Precautions when UDP protocol is selected
• If a new request message is sent to the same UDP port while the port waits for a response message, the
new request message is discarded.
• Setting same host station port number to multiple UDP ports is regarded as one setting. When
communicating with multiple external devices using the same host station port number, select TCP protocol.

Remark
Personal computers use the TCP socket functions internally for Ethernet communication.
These functions do not have boundary concept. Therefore, when data is sent by executing the "send" function once, the
"recv" function needs to be executed once, twice or more to receive the same data.
(One execution of the "send" function does not correspond to one execution of the "recv" function.)
For this reason, receive processing described above is required on the external device side.
If the "recv" function is used in blocking mode, data may be read by executing the function once.

(1) Communication time-out
A communication time-out occurs when the Built-in Ethernet port QCPU has not received time information for 20
seconds from when querying a time information server.
Besides, when a communication time-out occurs, the value in SD1270 changes to 0FFFFH.
(2) Time information server
To use the time setting function, an SNTP server personal computer (time information server) is required on LAN.
(3) Delay resulted from the time required for communication
A delay occurs with respect to the time set in the CPU module as a result of the time required for communication
with the server. Specify the closest SNTP server possible on the network.
(4) For multiple CPU system configuration
In a multiple CPU system, enable the time setting function of only the Built-in Ethernet port QCPU No.1.
When a CPU module other than the Built-in Ethernet port QCPU No. 1 is enabled, the clock data of the Built-in
Ethernet port QCPU No. 1 is automatically set.

CHAPTER3 COMMUNICATION FUNCTION USING BUILT-IN ETHERNET PORTS OF CPU MODULE
3.5.6 Precautions
Precautions for using the file transfer function are described below.
(1) FTP clients
• FTP command specifications may differ from those described in this manual, depending on the FTP client. In
such a case, check the functions and operation methods, referring to the manuals on the FTP client side.
• FTP operations cannot be performed from Microsoft
3
Internet Explorer. If performed, an error occurs with
Internet Explorer.
(2) Processing in Built-in Ethernet port QCPU
• Files only in the drives of the host station Built-in Ethernet port QCPU can be accessed.
• During file access, do not turn OFF the power supply, reset the CPU module or install/remove a memory
card. If any of these operations are performed, files may corrupt.
• During file access, do not perform any file operations from peripherals such as GX Developer. When a file
operation is performed from another peripheral during FTP function operation, an error may occur on the
peripheral side.
• During online change, do not perform any file operations using the FTP function. When a file operation is
performed, an error may occur.
• During file access using the FTP function, do not perform any online operations from peripherals such as GX
Developer. When an online operation is performed, an error may occur on the peripheral side.
• During backup or restoration of the CPU module change function using a memory card, an error occurs in
file access from FTP clients.
In that case, access the file again after the backup or restoration operation is completed.
Moreover, if the backup or restoration operation is performed during file access from FTP clients, an error
In that case, perform the backup or restoration operation again after blocking the communication with FTP
clients.
(3) Communication processing
• When a time-out error occurs during file transfer, the TCP connection will be closed (disconnected). To
restart the file transfer, log in to the Built-in Ethernet port QCPU once again from an FTP client.
• In a communication using FTP connections, an existence check of external devices is performed. For
operation details, refer to Section 3.1.3.
• The file transfer processing time depends on the following factors.
1) Load rate of the Ethernet line (line traffic)
2) Number of connections simultaneously used (communication processing of other connections)
3) System configuration
• The number of external devices (FTP clients) that can be simultaneously logged in to the Built-in Ethernet
port QCPU is only one. When another FTP client attempts the connection to the Built-in Ethernet port QCPU
which is in the logged-in status, connection cannot be established and an error occurs.
• If the File transfer function using the FTP is executed simultaneously with other communication functions
(MELSOFT connection, MC protocol) using the UDP, an error, such as a time-out error, may occur. Execute
other communication functions after file transfer is completed or communicate using the TCP.
3 - 40
3.5 File Transfer Function (FTP)
3.5.6 Precautions
occurs.
(4) Precautions for writing files
• Operation to overwrite an existing file cannot be performed.
Either delete the file using a file delete command (delete, mdelete) or rename the file using a file name
change command (rename) before writing the file.
• Files whose attribute is read-only or files which are locked by other devices/functions cannot be written. If
files are written, a write error occurs.
• File transfer (writing files) cannot be executed when a write-protected memory card is used. If files are
written, a write error occurs.
• When a file is written, a temporary file (FTP_I***.TMP) is created automatically. The name of this file is
changed to the name of written file upon normal completion. However, if the power failure or reset of the
CPU module occurs during the file write, this temporary file may remain. If this occurs, delete the temporary
file.
• When file registers are used in the standard RAM or SRAM card, change the CPU status to STOP first, and
then write /delete files to/in these drives.
• When file registers used in the standard RAM or SRAM card are set as auto refresh devices, do not write/
delete files to/in these drives.
• If large-capacity files are written to the ATA card during RUN, a load on write processing increases and a
communication error may occur. Change the CPU status to STOP to write large-capacity files.
(5) Precautions for deleting files
• The timing for deleting files is to be arranged by the user considering the overall system, including Built-in
Ethernet port QCPU and GX Developer.
• Files whose attribute is read-only or files which are locked by other devices/functions cannot be deleted. If
files are deleted, a delete error occurs.
• Deleting files cannot be executed when a write-protected memory card is used. If files are deleted, a delete
error occurs.

CHAPTER3 COMMUNICATION FUNCTION USING BUILT-IN ETHERNET PORTS OF CPU MODULE
3.6 Remote Password
This function checks a remote password when the communication using the following connections is requested.
• Communication using GX Developer
• Communication using the MC protocol
• File transfer
3
The remote password function is a function to prevent unauthorized access (ex. corrupting data and programs) from external
devices.
However, this function cannot completely prevent unauthorized access.
Users should incorporate safety measures by themselves if security of the programmable controller system needs to be
maintained against unauthorized access from external devices. We cannot be held responsibility for any problems caused
by unauthorized access.
[Examples of measures against unauthorized access]
• Install a firewall.
• Set up a personal computer as a relay station and control the relay of communication data using an application
program.
• Set up an external device that control access authority as a relay station.
Please consult a network provider or equipment sales company regarding external devices that can control
access authority.

Section 3.5.5)
CHAPTER3 COMMUNICATION FUNCTION USING BUILT-IN ETHERNET PORTS OF CPU MODULE
3.6.3 Precautions
Precautions for the remote password check function are described below.
(1) Setting remote password to UDP connections
• Determine the communication target external device and do not communicate with unspecified external
devices. (The communication target external device needs to be determined since UDP/IP connections can
communicate with any other devices, including the device that has performed unlock processing, after the
3
remote password unlocking processing is completed normally.)
• At the end of data communication, always perform the remote password lock processing.
(If lock processing is not performed, unlock status is held until a time-out occurs. When there is no
communication for 10 minutes, the CPU module automatically performs time-out based lock processing.)
To prevent unauthorized access more strictly using the remote password, it is recommended to set all connection
protocols to TCP/IP and disable GX Developer direct connection in parameter.
(2) Performing close processing before lock processing for TCP/IP connections
The CPU module automatically performs lock processing.
(3) Remote password valid range
The remote password is valid only for access from the Built-in Ethernet port QCPU for which the parameter
settings were made.
When multiple CPU modules are used in a multiple CPU system, set a remote password for each setting target
CPU module respectively.

3.6.4 Detection and corrective action of unauthorized access
When remote password mismatch count reaches the upper limit during unlock processing, an error (error code: 2700)
occurs in the Built-in Ethernet port QCPU.
The error cause is considered to be unauthorized access from outside of the system.
Perform the following corrective action as needed.
1) Monitor the Remote password count (SD979 to SD999) and check the connection that remote mismatch
count reaches the upper limit during unlock processing.
2) Disable the communication by making the corresponding connection invalid. The corresponding connection
can be set to invalid by the operation described below.
• By selecting the target connection on the Status of each connection tab, which is displayed by clicking
the "Built-in Ethernet port diagnostics" button on the PLC diagnostics screen in GX Developer.
(
QCPU Userís Manual (Hardware Design, Maintenance and Inspection))
Figure 3.34 Ethernet diagnosis screen
• By turning ON the forced invalidation flag (bit) of the corresponding connection using the special
registers (SD1276, SD1277).
3) Clear the error (error code: 2700).
The remote password count (SD979 to SD999) is cleared in accordance with clearing of the error.
4) Inform the system manager that the number of error completions of unlock processing is exceeding the
mismatch limit and take appropriate corrective actions.
To prevent such errors, perform the following operations.
• Check the checkbox of "Clear mismatch count when remote password matches" on the Remote password detail
settings screen in GX Developer.
• Clear the accumulated count of remote password mismatches using the special relay (SM1273).
