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) 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.
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 Page 670, Appendix 9.
(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.
1
[Design Precautions]
WARNING
● 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.
[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.
● 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.
● 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.
2
[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets the general specifications in this
manual. 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 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.
● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
● When using an extended SRAM cassette, fully insert it into the connector for cassette connection of
the CPU module. Close the cassette cover after inserting to avoid looseness of the extended SRAM
cassette. Poor contact may cause malfunction.
● 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 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 this manual and in the manual for the corresponding module.
● Do not directly touch any conductive part of the module, the memory card, the SD memory card, or
the extended SRAM cassette. 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.
[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 damage to the product.
● After installation and wiring, attach the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.
3
[Wiring Precautions]
CAUTION
● Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 or less. Failure to do so may result in electric shock or malfunction.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in
failure.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
● Connectors for external connection must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections could result in short circuit, fire,
or malfunction.
● Install the connector to the module securely. Poor contact may cause malfunction.
● 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.

(4) Increase in debugging efficiency through high-speed communication with a
programming tool
High-speed communications at 115.2Kbps maximum are available by using RS-232 which reducing the time
required for writing and reading of programs and monitoring. Also, the communication time efficiency of
debugging has been increased.
In addition, High Performance model QCPUs (except for the Q02CPU), Process CPUs, Redundant CPUs and
Universal model QCPUs support USB, so that high-speed communications of 12Mbps are available.
(5) Use of AnS/A series I/O modules and special function modules
The AnS/A series compatible extension base units (QA1S5B, QA1S6B, QA1S6ADP+A1S5B/A1S6B,
QA6B, and QA6ADP+A5B/A6B) can be connected to the main base unit where the High Performance
model QCPU or Universal model QCPU

(7) Connection of up to 7 extension base units
Remark
Up to seven extension base units can be connected to the Q series CPU module.
The overall extension cable length is 13.2m, which allows flexible layout of base units.
(8) Memory extension
By extending the memory capacity of a CPU module, large size files can be managed. Comments can be set to
all data devices and old programs can be saved as correction history.
(a) Memory card
A memory card (maximum 32M bytes) can be installed. (The maximum size is available only for ATA cards.)
Memory cards are used for the following operations.
• Boot operation
• Restoring backup data
• Writing programs to the ROM
Data that cannot be stored in the built-in memory of the CPU module, such as sampling trace data and file
register data, can be stored as well.
(b) SD memory card
SD memory cards are used for the following operations.
• Boot operation
• Restoring backup data
• Data backup
• Data logging
(c) Extended SRAM cassette
An extended SRAM cassette extends the capacity of the standard RAM in a CPU module.
• An extended SRAM cassette can be used together with an SD memory card, allowing users to store data
separately (for example, boot data in an SD memory card and device data in an extended SRAM
cassette). This improves maintainability.
• With existing CPU modules, file register areas in the standard RAM and an SRAM card cannot be
accessed sequentially, and the boundary needs to be considered at programming. If the standard RAM
capacity is extended using an extended SRAM cassette, the device area can be extended without
considering the boundary.
Memory extension methods differ depending on the CPU module. (Page 35, Section 2.2)

CHAPTER 1 OVERVIEW
Note 1.1, Note 1.2
Note 1.1
Note 1.1
(9) Automatic write to the standard ROM Note 1.1 Note 1.2
Parameters and programs in a memory card or SD memory card can be written to the standard ROM of the CPU
module without using a programming tool.
If the boot operation is being performed from the standard ROM, parameters and programs in a memory card or
SD memory card can be written to the standard ROM by inserting it to the CPU module. Users do not need a
programming tool (personal computer) on hand to modify parameters and programs.
(10)External input/output forced on/off
Forced on and off of external input and output is available using a programming tool even when the CPU module
is running or program is being processed.
Also, wiring test and operation test can be conducted without halting the CPU module by forcibly turning on or off
the I/O.
(11)Remote password function
When the built-in Ethernet port QCPU, Ethernet module, or serial communication module is externally accessed,
an access to the CPU module can be controlled by setting a remote password.
(12)Remote I/O network of MELSECNET/H
A MELSECNET/H remote I/O system can be configured by installing a MELSECNET/H remote master station.
1
● The remote password can be set up when the Ethernet module, or serial communication module of function version B or
later is used.
● The MELSECNET/H remote I/O network can be implemented when the MELSECNET/H network module of function
version B or later is used.
(13)Support of multiple CPU systems
CPU module supports the multiple CPU system.
Multiple CPU systems can be constructed in combination with CPU modules, motion CPU(s), PC CPU module(s),
and C Controller module.
For details of the multiple CPU system, refer to the following.

(14)Support of redundant power supply systems
Note 1.3
The redundant power supply system can be configured using a redundant base unit and redundant power supply
modules.
The system can continue operation even if one of the power supply modules fails, since the other will supply the
power.
(15)Direct connection to EthernetNote 1.3
The Built-in Ethernet port QCPU module allows direct connections to Ethernet.
For details of the functions, refer to the following.
QnUCPU User's Manual (Communication via Built-in Ethernet Port)

(6) Precautions for the number of mountable modules
Mount modules so that the total number of I/O points does not exceed the point range of the CPU module.
Modules can be mounted in any slot within the available range.
Even if the total number of slots of the main base unit and extension base units exceeds the number of available
slots (for example, even if six12-slot base units are used), no error occurs as long as modules are mounted within
the available range.
If a module is mounted exceeding the available range, "SP.UNIT LAY ERR." (error code: 2124) occurs.

CHAPTER 4 INSTALLATION AND WIRING
4.2Mounting a Module
4.2.1Mounting precautions
This section describes precautions for handling CPU modules, I/O modules, intelligent function modules, power supply
modules, and base units.
• Do not drop or apply strong shock to the module case, memory card, SD memory card, extended SRAM
cassette, terminal block connector, and pin connector.
• Do not remove the printed-circuit board of a module or extended SRAM cassette from the case.
Doing so may cause failure of the module and/or printed-circuit board.
• Tighten the module fixing screws and terminal block screws within the specified torque range shown in the
following table.
ScrewTightening torque range
Module fixing screw (M3 × 12)0.36 to 0.48N•m
I/O module terminal block screw (M3)0.42 to 0.58N•m
I/O module terminal block fixing screw (M3.5)0.66 to 0.89N•m
Power supply module terminal screw (M3.5)0.66 to 0.89N•m
• Be sure to install a power supply module in the power supply installation slot of Q3B, Q3SB, Q3RB,
Q3DB, Q6B, Q6RB, Q6WRB, QA1S6B or QA6B.
Even if the power supply module is not installed, when the I/O modules and intelligent function module
installed on the base units are of light load type, the modules may be operated.
In this case, because a voltage becomes unstable, we cannot guarantee the operation.
• When using an extension cable or a tracking cable, keep it away from the main circuit cable (high voltage
and large current).
Keep a distance of 100mm or more from the main circuit.
• The following are precautions on use in combination with a module whose depth is 130mm or more (such as
Q66DA-G).
1) A module that is less than 130mm in depth cannot be mounted between modules that are 130mm or
more in depth.
2) A module that is less than 130mm in depth cannot be mounted on the right side of a module that is
130mm or more in depth.
3) When the power supply module Q64P(N) is used and a module that is 130mm or more in depth is
mounted in slot 0, it may be difficult to mount/remove a CPU module or insert/remove a memory card.
Although there is no problem with the system operation, if it is inconvenient, mount a module that is less
than 130mm in depth in slot 0 or leave the slot empty.
4
4.2 Mounting a Module
4.2.1 Mounting precautions
In case of using the QA1S6B, when installing the base unit to DIN rail in an environment of frequent vibration, use a
vibration-proofing bracket (A1S-PLT-D). Mounting the vibration-proofing bracket (A1S-PLT-D) enhances the resistance to
vibration.
Depending on the environment to install the base unit, it is also recommended to secure the base unit directly to the control
panel.

(1) Instructions for handling an extension cable
• Do not step on an extension cable.
• Connect the extension cable to the base unit with the base cover installed to the base unit.
(After you have set the extension number to the extension base unit, reinstall and screw the base cover.)
• When laying an extension cable, secure 55mm or more as the minimum cable bending radius.
If it is less than 55mm, a malfunction may occur due to characteristic deterioration, cable disconnection or
the like.
• The overall length of extension cables must be up to 13.2m.
• Do not install extension cables with the main circuit (high voltage and large current) line.
• When connecting or disconnecting an extension cable, do not hold the ferrite cores mounted at both ends of
the cable.
Hold the connector part of the cable for connection or disconnection.

When connecting an extension base unit to the main base unit with an extension cable, plug the OUT side connector of the
main base unit and the IN side connector of the extension base unit with an extension cable. The system will not operate
properly if the extension cable is connected in the form of IN to IN, OUT to OUT or IN to OUT.
When connecting two or more extension base units, plug the OUT side connector of the first extension base unit and the IN
side connector of the second extension base unit with an extension cable.
1. To connect an extension cable to the main base unit, remove the portion under the OUT characters
on the base cover with a tool such as a flat blade screwdriver (5.5 × 75, 6 × 100).
This also applies to a case where an extension cable is connected to the OUT side connector of
the extension base unit. When connecting an extension cable to the Q00JCPU and Q00UJCPU,
remove the base cover manually. To remove the base cover, insert the tip of a screwdriver into a
clearance below the base cover and pry it up. Be careful not to damage the connector when
inserting the screw driver since a connector is located inside the base cover.
2. To connect the extension cable to the next extension base unit, remove the seal put under the IN
characters on the base cover.

4.3.4Voltage drop when an extension base unit is used
Since the extension base unit (Q5B or QA1S5B) is supplied with 5VDC from the power supply module on the main
base unit, a voltage drop occurs at extension cables. Improper I/O may occur if the specified voltage (4.75VDC or
higher) is not supplied to the "IN" connector of the Q5B or QA1S5B.
When using the Q5B or QA1S5B, make sure that the "IN" connector of the Q5B or QA1S5B is supplied with
4.75VDC or higher.
And it is recommended to connect either of the extension base units as close as possible to the main base unit by
using the short extension cable, so as to minimize the effects of voltage drop.
(1) When only the Q5B or QA1S5B is connected to the extension base unit
(a) Selection condition
4.75VDC or higher must be supplied to the "IN" connector of the Q5B or QA1S5B in the final extension
base.

Voltage drop caused by extension cable from the
main base unit to the Q5B IN connector (V)
The voltage supplied to the "IN" connector of the Q5B reaches 4.75 VDC or higher on the condition that the voltage drop (V)
at the extension cable between the main base unit and Q5B is 0.15 VDC or lower.
When connecting GOT by extension cable that is 13.2m or longer, the bus extension connector box A9GT-QCNB is
required.
Since the A9GT-QCNB is supplied with 5VDC from the power supply module loaded on the main base unit, 30mA must be
added to "Im" as the current consumption of the A9GT-QCNB.

4.5 Installing and Removing a Memory Card
97
Observe the following precautions when installing or removing a memory card while power is on.
● Note that the data in a memory card may be damaged if the above procedure is not followed. If the operating status of the
CPU module at the time of an error is set to "Stop" in parameter, the CPU module stops its operation upon the occurrence
of "ICM.OPE.ERROR".
● When a memory card is installed, the scan time of the CPU module increases by several 10ms (maximum). The scan
time increases for only one scan where the CPU module performs the mount processing.
● Poor insertion of the memory card may result in "ICM.OPE.ERROR".
● Using the tweezers below is effective when the memory card cannot be removed smoothly.
