SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using products introduced in this publication, please read relevant manuals and replacement
handbooks carefully and pay full attention to safety to handle the product correctly.
In this publication, 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 publication and keep it 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) 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 General Safety Requirements 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.
WARNING

A- 2
[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/special
function module, configure an interlock circuit in the sequence 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, 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 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.

A- 3
[Installation Precautions]

This transition handbook describes the model selection of CPU modules and I/O modules after
replacing models, for the transition from the MELSEC-AnS/QnAS series to the Q series.
At the transition from MELSEC-AnS/QnAS series to Q series, some items such as the replacement
procedure, installation location, specifications comparisons between existing modules and replaced
modules, and replacement method are required to be considered beforehand.
The following shows major options. Consider them sufficiently in advance. (It is necessary to understand
the existing system configuration before making considerations.)
(Major items required to be considered in advance)
1) Replacement methods and installation location
a) Whether gradual replacement (only the CPU module is replaced with Q series, etc.) or batch
replacement for the replacement method of the existing system. When replacing it gradually,
which existing modules should be leveraged (left).
b) Whether some space can be reserved when adding a base unit at the replacement work.
2) Replacement schedule
3) Model selection after replacing models (I/O module)
a) Whether a module whose specifications (rated input current, etc.) and functions are equivalent
to that of the existing module exists or not in the Q series.
b) Whether utilizing the existing modules continuously or replacing them with Q series modules.
c) Whether utilizing the existing external wiring or wiring newly.
4) Model selection after replacing models (intelligent function module (analog, high-speed
counter module, etc))
a) Whether the specifications of replaced modules and connection external device match or not.
5) Model selection after replacing models (communication module (computer link module,
Ethernet module etc))
a) Whether the communication target device is compatible with the Q series module commands
in the communication using the MC protocol or not.
b) Whether the communication target device software (program) can be changed to Q series
CPU-compatible or not.

6) Model selection after replacing models (network module (MELSECNET (II), MELSECNET/
MINI(-S3)))
a) Whether the replacement of MELSECNET (II) is a gradual replacement or batch replacement
for.
b) Whether local stations and remote stations can be grouped into two networks, PLC-to-PLC
network and remote I/O network, by replacing to MELSECNET/H when the local stations and
remote stations are mixed in the existing MELSECNET (II).
c) Whether a new communication cable installation has been considered or not at the
replacement from MELSECNET/MINI(-S3) to CC-Link.
7) Program utilization
a) Whether utilizing the program in the existing system or creating a new program.
b) Whether the workload and cost of correction have been considered or not when utilizing the
program of intelligent function module and communication module (nonprocedural mode).

1.2.1 Advantages of transition to Q series
(1) Advanced performance of equipments (Tact time reduction).
The Q series includes faster operation processing speed, faster bus speed and dual processors of
Super MSP (MELSEC SEQUENCE PROCESSOR) and general-purpose processor to provide over 5
times more efficient processing than the AnS/QnAS series. This realizes more advanced performance
of equipments.
(2) Compact control panel and space saving
Comparing to the AnS/QnAS series, the Q series requires 60% mounting area, which allows installing
compacter control panel.
(3) Improved maintainability
(a) The high-speed program ports (Ethernet port, USB port, and high-speed serial port) enable the
program reading/writing time to be greatly reduced, resulting in improvement of on-site
maintainability.
(b) The Universal model QCPU does not require the ROM operation because the program memory
is the flash ROM.
(c) As large files can be managed, it is possible to store conventional programs as correction
history in memory.
(4) Easy support for information systems
The Web server module, MES interface module, and high speed data logger module can perform
remote monitoring of programmable controller CPUs and perform data collection for quality control and
traceability. Information can be easily gathered from the factory using a Web server module once
transition from AnS/QnAS series to Q series has been completed.

1.2.2 Suggestions for transition to Q series
(1) Transition to Q series by utilizing existing wiring
*1 The terminal block cover (from the old terminal block) must be exchanged.
Remarks
(1) Upgrade tool for transition from the AnS series to the Q series released from Mitsubishi Electric
Engineering Co., Ltd. is composed of the following products.
For example, using the conversion adapter allows utilizing the wiring connected to the AnS series
I/O module for the Q series module without change.
For details, refer to the "Upgrade Tool General Catalog" issued by Mitsubishi Electric Engineering
Co., Ltd.
(2) Using outside connection method, the existing wiring for AnS series input/output module
connector type is usable. (No need to change the wiring, only move the connecter to the Q series
module.)
Moreover, it is possible to mount a module used with the upgrade tool on the same base unit.
(3) When the existing extension base unit is A type series, refer to the Transition from MELSEC-A/
QnA (Large Type) Series to Q Series Handbook (Fundamentals).
Method : Use the upgrade tool manufactured by Mitsubishi Electric Engineering Co., Ltd. and the
existing mounting hole/terminal block wiring.
Advantage: No need to process additional holes, and the existing wiring is usable.
• Conversion adapter for changing the existing wiring connected to the AnS series I/O module to
wiring for the Q series I/O module
• Base adapter which utilizes the mounting hole of the AnS series base unit for mounting Q
