[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.
Status Q Series module A/AnS Series module
Overcurrent or overvoltage protection

All outputs are turned off. All outputs are turned off.
of the power supply module is activated.
The CPU module detects an error such as All outputs are held or turned
a watchdog timer error by the self-diagnostic off according to the parameter All outputs are turned off.
function. 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.
● 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.

[Design Precautions]
WARNING
● 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 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.
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.
● The time for the CPU module to enter the RUN status after the CPU module is powered off and on or reset
will vary depending on the system configuration, parameter settings, and/or program size, etc.
Design the program so that the entire system will operate safely even if the time to reach the RUN status
varies.

1. Comparison of base mounting area

1.1 Comparison of A/QnA (Large Type) Series and Q Series base unit mounting area
When upgrading existing A/QnA systems, there are cases where the number of modules increases due to
specification differences. For instance, to replace an A/QnA Series 32-point terminal block type I/O module, two
Q Series 16-point terminal block type I/O modules are used. Despite increase in the number of I/O slots and
extension base stages, the Q Series footprint is smaller than that of the A/QnA Series.
The following example shows a comparison of the mounting areas when the A/QnA Series system is upgraded
to the Q Series.
Solution and Benefit

When replacing each 32-point terminal block type module with two 16-point terminal block type
modules, an additional extension base unit is required due to an increase in the number of modules.
However, the Q Series system fits inside the existing control panel because it is compact in size.

1.2 Comparison of QnS/QnAS (Small Type) Series and Q Series base unit mounting area
The Q Series is compact, and has a smaller mounting area.
It can be mounted within the AnS/QnAS (Small Type) mounting area.
The following example shows a comparison of the mounting areas when the AnS/QnAS (Small Type) Series
system is upgraded to the Q Series.

Using the “AnS to Q Series conversion adapter” (manufactured by Mitsubishi Electric Engineering
Co., Ltd.), the 16-point terminal block type module can fit into the existing space without changing
the wiring.

Q38B 328(W)×98(H) Width is 3 mm wider



Tip
The AnS /QnA (Small Type) Series main base unit and extension base unit differ in size:
• A1S35B main base unit: 325 mm (W) x 130 mm (H)
• A1S65B extension base unit: 315 mm (W) x 130 mm (H)
• Q38B main base unit/A68B extension base unit: 328 mm (W) x 98 mm (H)
The width will increase if the number of modules increases, i.e., A1S35B to Q68B will increase 3 mm, and
A1S38B to Q312B will increase by 9 mm.
However, this increase can be handled. Confirm the in-panel layout and space and determine whether the
extra modules can be mounted.

2. Install terminal block converter module and terminal module externally

2.1 Replace 32-point terminal block type module using connector/terminal block
converter module
• The connector/terminal block converter module can support up to 2mm2 wires, allowing the use
of existing thick wires without modification.
• Using a connector/terminal block converter module, an existing 32-point terminal block type
module can be replaced with a 32-point connector type module without increasing the number of
modules.
The following is an example of replacing an A/QnA system that contains 32-point terminal block type input
modules (AX41).
A. Instructions
Replace AX41 with QX41 (32-point connector type module), and connect the connector/terminal block
converter module.
If QX40 (16-point terminal block type module) is used instead of QX41, two modules are required to replace
each AX41. Also, if existing wires are thicker than the applicable wire size (0.75 mm2), wiring modifications
may be necessary.

2.2 Replace 32-point contact output type module using relay terminal module

• Using the relay terminal modules, a large type A Series 32-point contact output module can be
replaced while maintaining 8 points/common.
• A wide variety of compatible wire sizes are available using the relay terminal module.
A Series 32-point contact output module AY13: Max. 2 mm2
Relay terminal module: Max. 1.25 mm2
Q Series 16-point contact output module QY10: Max. 0.75 mm2
• Replacement is possible without the need of additional modules because a module mounted on
the base unit becomes compatible with 32-point connector type modules through the use of the
"connector/terminal block converter module".
The following is an example of replacing contact output modules (AY13) with transistor output modules (QY41P)
and externally converting transistor outputs into contact outputs.
A. Instructions
Replace AY13 with QY41P and connect the relay terminal modules to convert to contact outputs.
With this method, the system can be upgraded without increasing the number of modules on the base unit.
Also, 8 points/common, the same specification as that of the AY13, can be maintained.

Tip
• Existing A Series wiring harness plugs in without modification.
• The Q Series large type base units and I/O modules are compatible with High Performance Model QCPUs,
Universal model QCPU (except Q00UJCPU), and MELSECNET/H Remote I/O Stations. Basic Model
QCPUs, Process CPUs, Redundant CPUs, and Safety CPU are not compatible.
• Neither Q Series large type main base unit nor Q Series large type extension base unit can be used in a
multiple CPU system.
• The standard Q Series modules can be mounted on the Q Series large type base unit using the Q Series
large type blank cover.
• The Q Series large type base units can be used together with the standard Q Series base units.
(e.g., main base unit: Q312B, extension base unit: Q68BL)
• Some modules, such as modules that occupy two slots, cannot be mounted. Refer to “Q Series Large Type
Base Unit/I/O Module/Blank Cover User’s Manual” for details.
• After replacing the existing connector with the wiring intact, the 64-point connector type I/O module can be
used for the Q Series I/O module.
A blank cover is required to mount the Q Series large type base unit.
Note that the connector layout changes from top/bottom to left/right, so the position of the lower connector
moves to the upper side.
Check that the existing wiring is long enough.
• The 8-slot no power supply required type is not available for the Q Series extension base unit.
When replacing the existing extension base unit to the 8-slot no power supply required type A58B, replace
with the power mounted type Q68BL.
In this case, the mounting width dimensions will increase by 55 mm (411 mm to 466 mm).
Confirm the mounting space, and that the wiring is long enough to move to the mounting position.
• 2-slot type conversion adapters of the upgrade tool manufactured by Mitsubishi Electric Engineering Co., Ltd.
cannot be used.
• For details on the upgrade tool manufactured by Mitsubishi Electric Engineering Co., Ltd., please contact
your local Mitsubishi sales office or representative.

3.1 Upgrade to Q Series modules using Q Series large type base unit

• Unlike the QA6�B extension base unit, which is used to directly mount existing A Series I/O
modules for a gradual upgrade, the Q Series large type base unit, I/O module, and conversion
adapter (upgrade tool) enables all modules to be upgraded to the Q Series at once and allows use
of existing A Series wiring.
• Having the same slot width as A Series base units, the Q Series large type base units permit
direct mount of existing 32-point I/O wiring on the Q Series I/O modules. This can shorten the
upgrade time.
• Performance specifications of the Q Series large type I/O modules are equivalent to those of the A
Series, eliminating concerns about compatibility with the connected external devices.
The following is an example of upgrading an A Series system to the Q Series using the Q Series large type base
units, I/O modules, and conversion adapters.
A. Instructions
(1) Replace the existing 32-point terminal block type I/O modules with Q Series large base units and I/O
modules, and use the same terminal blocks to connect with external wiring.
(2) If there is no compatible Q Series large type I/O module, use the conversion adapter to replace the existing
module with standard Q Series I/O module.

*1: The module mounting slot position differs, so the wiring length must be adjusted.
*2: If the I/O modules are mounted adjacently using the conversion adapter, mounting may not be possible if the existing wires are thick or
there are many wires. If the wires interfere, lift the wires up toward the front so they are out of the way. If the wires still interfere, leave
one slot open to ensure space for the wires.

Tip
• External wiring work is eliminated by directly mounting the existing AnS/QnAS (Small Type) I/O module
terminal block.
When using the conversion adapter, the terminal block cover (enclosed with conversion adapter) must be
replaced.
• When replacing the AnS/QnAS Series I/O module with connector type external connection method (wiring),
the existing wiring can be used. (The connector, with wires attached, can be connected to the Q Series
module.) Note that after replacement, the Q Series does not have a D-sub 37-pin connector type I/O
module, so the wiring must be changed to a 40-pin connector.
Note that units with and without the conversion adapter can be used together on the same base unit.
• If replacement is difficult from the existing AnS/QnAS (Small Type) I/O module, the module can be replaced
with the FA goods interface terminal module.(Example: When A1SX20 is replaced, two QX28 modules will
be required. This increases the number of modules and changes the address. By selecting QX40 and
providing the FA goods terminal module “FA-TH16X200A31L” externally, the number of modules does not
need to be increased, and the address will not change.)
• When replacing a system containing an A Series large type extension base unit connected to the
AnS/QnASCPU to the Q Series, the “Q Series large type base unit, Mitsubishi Electric Engineering Co., Ltd.
Upgrade Tool” can be used to replace the A Series large type extension base unit and mounted modules.
Refer to the following section for tips on selecting the “Q Series large base unit, Mitsubishi Electric
Engineering Co., Ltd. Upgrade Tool” in this case.

4.4 Select the DC input module replacement module
Tips for selecting replacement module

A. Rated input voltage
When selecting the replacement for the DC input module, many of the existing A (Large Type) and A
(Small Type) modules have a rated input voltage of 5, 12 or 24 V DC.
The replacement Q Series module is 12 V (some units are 5 or 12 V DC) or 24 V DC so the selected
module may differ depending on the existing module working state.
Always confirm the working state of the existing module when selecting the replacement.
(Excerpt from L(N)08043: Replacement Handbook)
B. Common terminal arrangement

A positive common type and negative common type DC input module are available.
The existing A (Large Type) and A (Small Type) have positive common/negative common shared types.
When selecting a replacement for the positive common/negative common shared type, a positive common type
or negative common type must be selected since a shared type is not available with the Q Series modules.
Always confirm the working state of the existing module when selecting the replacement.
Refer to the following handbooks for detailed specifications on each module.
• Transition from MELSEC-AnS/QnAS (Large Type) Series to Q Series Handbook (Fundamentals):
L(NA)08043
• Transition from MELSEC-AnS/QnAS (Small Type) Series to Q Series Handbook (Fundamentals):

C. Using existing wiring

(1)Terminal block type module
When replacing the terminal block type module, the existing A (Large Type) or A (Small Type) module’s
terminal block can be used in the wired state by using the conversion adapter. This eliminates the need to
change the wiring.
(2)Connector type module
If the connector type on the connector type module is the same (i.e., 40-pin connector to 40-pin connector,
etc.), the wiring can be used.
If the connector type differs (i.e., D-sub 37-pin connector to 40-pin connector, etc.), the wiring must be
changed.

5.1 Replace A0J2(H) systems with Q Series using existing wiring

• Existing A0J2 I/O wiring can be mounted on the A0J2 renewal tool without modification.
• The A0J2 renewal tool takes in AC/DC input and sends these signals to a programmable
controller's input module. It also outputs the signals received from a programmable controller's
output module to the external devices. Therefore, any A0J2 Series I/O modules can be replaced
with QX41Y41P by selecting the appropriate A0J2 renewal tool.
• QX41Y41P, the 64-point I/O combined module (32-point input for the first half and 32-point output
for the second half), can be used to replace the A0J2 Series I/O modules without changing the I/O
assignment.
• The installation size of the A0J2 renewal tool is the same as that of the A0J2-E56� I/O modules,
eliminating the need of making new holes.
The following is an example of replacing an A0J2(H) system with Q Series using the A0J2 renewal tool.
A. Instructions
(1) Replace the A0J2H Series CPU with a Q Series CPU and the I/O modules with QX41Y41P. The existing
I/O address can be used for the QX41Y41P.
(2) When the A0J2 renewal tool is used to mount the terminal blocks of the existing A0J2 I/O modules, the
existing external wiring does not need to be changed.
* The A0J2 renewal tool is not assigned an I/O module number. The "No.=n" in the new configuration keeps
track of the order of connection with the modules on the programmable controller side to avoid changes in
I/O addresses. Check the I/O module number in the current configuration and connect the programmable
controller side modules accordingly.

Tip
• When using the stackable type, check that there is enough depth.
Also, check the width when using a programmable controller main/extension base unit with 5 slots because it
may have increased.
• Select the appropriate cable length between the interface module and the programmable controller (I/O
module) depending on the system configuration.
• The I/O addresses (X/Y addresses) of existing A0J2 I/O modules are preset according to the I/O module
numbers. Check the I/O module number that has been set for each existing module.
Connect the A0J2 renewal tool with the I/O modules in a way that the same I/O addresses are used when
upgrading to Q Series CPU.
• When an output-only module such as SC-A0JQIF24R is used, selecting QY41P as the programmable
controller side module changes the I/O addresses and requires program modification.
In this case, the start I/O address of the affected slots can be re-assigned in I/O assignment of Q Series CPU
parameter in order to avoid changes to the program.
• 24 V DC output power supply of the Q62P can be used as an external power supply for the A0J2 renewal
tool. However, depending on the number of modules used, an extra power supply may be needed. In this
case, prepare an external 24 V DC power supply.

5.2 Upgrade to MELSECNET/H remote I/O network system (using A0J2 renewal tool)

• Using the A0J2 renewal tool, A0J2R25/A0J2P25 remote I/O stations can be replaced with
MELSECNET/H remote I/O stations without modifying external wiring.
• By making the same network parameter settings as the current ones, program modifications can
be avoided.
The following is an example of upgrading a MELSECNET network system consisting of only remote I/O stations
to a MELSECNET/H remote I/O network system using the A0J2 renewal tool.
A. Instructions
(1) Replace the MELSECNET network system with MELSECNET/H remote I/O network system. The network
parameter settings remain the same, and it is not necessary to make changes to the program.
(2) Change the cable system from MELSECNET coaxial loop to MELSECNET/H coaxial bus. New wires are
not necessary because the existing coaxial loop cables can be used.

Tip
• The existing A Series base unit and mounted modules can be utilized without wiring modification. Also, the
I/O modules on the existing A Series main base unit are just remounted on the QA6�B extension base unit
without the need for rewiring.
• By using the same I/O address for the existing modules, program modifications can be minimized.
• The following A Series modules need to be replaced with a Q Series CPU compatible model.
Ethernet module
Ethernet module, computer link module
etc.
• The A6�B/A5�B extension base unit with the QA6ADP cannot be used together with the QA1S6�B
extension base unit.
• When an AC input module is mounted on the “A5�B” extension base unit (without power supply) using the
QA6ADP, either the “A6�B with QA6ADP” or “QA6�B” extension base unit (with power supply) is required in
the system.
• Set the stage number for QA6ADP according to the setting of the extension base unit.
• The QA6ADP adapter is compatible with High Performance Model QCPUs only. Basic Model QCPUs,
Process CPUs, Redundant CPUs, Safety CPUs, Universal Model QCPUs, and Remote I/O Stations are not
compatible.
• The QA6ADP QA conversion adapter is only compatible with High Performance Model QCPU or Universal
Model QCPU (first five digits of serial No. “13102” or higher).

6.3 Use AnS/QnAS (Small Type) Series QA1S6�B extension base unit

•By using the current AnS/QnAS (Small Type) module, the wiring work during replacement can be
reduced. Replacements can be completed in a short time.
•Replacement is possible even if a compatible Q Series module is not available.
•If an extension base unit is connected to the current AnS/QnAS (Small Type) series, it can be used
together with the A/QnA (Large Type) QA6�B extension base unit.
The CPU can be replaced with the QCPU. An example of using a current A (Large Type) module without
modification to shorten the re-wiring man-hours is shown below.
(1) Only the CPU is replaced to the Q Series. The current I/O module is used.
Replace the existing AnS/QnAS (Small Type) main base A1S35B to QA1S65B, and mount the existing
module.
(2) If the module must be replaced with the Q Series, select the module and then mount on the Q Series main
base unit.
(3) Avoid changing the current I/O assignments.

Tip
• The existing AnS/QnAS (Small Type) main base unit can be used without modifying the wiring by replacing
with the extension base QA1S6�B and remounting the mounted modules.
The existing A (Large Type) extension base unit can be used without modifying the wiring by replacing with
the extension base QA6�B, and remounting the mounted modules.
• The QA1S6�B extension base unit cannot be used together with the A (Large Type) extension base A6�
B/A5�B) onto which QA6ADP is mounted.
When using a module mounted on the existing A (Large Type) extension base unit, replace the base unit
with the QA6�B extension base.
• Connect the base units in the following order.
Q Series main base unit lQ Series extension base unit lQA1S6�B extension base lQA6�B

The GOT bus cannot be connected when the QA6�B extension base is connected.
The GOT bus can be connected when only the QA1S6�B extension bus is connected.
• Program modifications can be minimized by using the same I/O address for the existing units and setting the
current I/O addresses with the parameter I/O assignments.
• The following A/QnA (Large Type) module and AnS/QnAS (Small Type) module cannot be used with the Q
Series CPU.
These must be changed to a Q Series CPU compatible module.

6.4 Utilize existing A (Large Type) and AnS (Small Type) modules without
changing I/O addresses
• The I/O addresses do not need to be changed when reutilizing existing A Series modules with Q
Series CPU and mounting the modules on QA6�B/A6�B＋QA6ADP. This can greatly reduce
program modification time.
• The A (Large Type) and AnS (Small Type) modules can be used with the same I/O addresses, so
there is no need to change the external wiring numbers.
The following is an example of how to reuse the program without modifying the I/O addresses when replacing the
CPU with a Q Series CPU and keeping the existing I/O modules on a QA extension base unit.
A. I/O assignment example

When utilizing existing A (Large Type) and AnS (Small Type) modules with the Q Series CPU, set the existing
module’s I/O addresses to the existing addresses with the PC parameter I/O assignment settings. Assign the
addresses for the modules mounted onto the main base unit after the existing module. This will greatly reduce
program modification time.

7. Replace MELSECNET/MINI(-S3) with CC-Link

7.1 Replace A2CCPU with Q Series CPU and CC-Link
(using A2C shape CC-Link I/O modules)
• A2C shape CC-Link remote I/O modules have been developed to replace MELSECNET/MINI(-S3)
systems with CC-Link. Wiring time is reduced because existing terminal blocks can be mounted
directly on the A2C shape CC-Link remote I/O module by merely changing the communication
and power lines.
• Since the mounting size is the same as that of A2C I/O modules, the new modules can be
mounted using existing holes.
The following is an example of replacing an A2CCPU with a Q Series CPU and A2C I/O modules with A2C
shape CC-Link remote I/O modules.
A. Instructions
(1) Replace the stand alone A2CCPU with the building block type Q Series CPU.
(2) Replace the A2C I/O modules with the A2C shape CC-Link remote I/O modules while maintaining
the distributed I/O system.
(3) Change the communication cables with CC-Link dedicated cables, and rewire the power cables.

7.3 Replace MELSECNET/MINI(-S3) remote I/O station (building block type: AJ72PT35)
with MELSECNET/H using the existing external wiring
• MELSECNET/H (remote I/O network) can utilize Q Series large type base unit. Wiring time can be
reduced by utilizing the external wiring of MELSECNET/MINI remote I/O station, which consists of
existing building block type I/O modules.
• Program modification is not required because the number of occupied points are the same for
each I/O module to be replaced. Therefore, programming time and debugging time after the
replacement is reduced.
A. Instructions
(1) Replace the existing MELSECNET/MINI(-S3) with MELSECNET/H (remote I/O network).
Install new network cables: optical cable (loop) or coaxial cable (bus).
(Optical cables are used for the following example.)
(2) When the I/O module of the existing MELSECNET/MINI(-S3) remote I/O station is of terminal block type,
utilize the existing terminal block with the external wiring through a Q Series large type base unit and the
following products.
• Q Series large type I/O modules
• Q Series I/O modules + upgrade tool manufactured by Mitsubishi Electric Engineering Co., Ltd.
(3) In MELSECNET/H (remote I/O network) network parameter, set the master station side devices to be the
same as the ones assigned to the existing MELSECNET/MINI in order to avoid program modification.

Tip
•The installation of MELSECNET/MINI twisted pair cables needs to be modified according to the upgraded
network. In the example, optical dual loop is selected to loop the network. When the distance between
stations or overall distance is short, a coaxial bus cable can be used to reduce cable installation time.
• Some CPUs, such as Basic Model QCPUs (Q00J, Q00, Q01CPU), cannot be set as MELSECNET/H
(remote I/O network) master station.
For selecting CPU type, refer to "Q corresponding MELSECNET/H Network System Reference Manual
(Remote I/O network)" SH-080124.
• If modules other than building type I/O modules, such as A2C I/O modules, are mixed in the existing
MELSECNET/MINI(-S3) system, the entire system cannot be upgraded to MELSECNET/H (remote I/O
network).
In this case, consider separating the system into MELSECNET/H (remote I/O network) and CC-Link.

Tip
Unless the existing network is in MELSECNET mode or MELSECNET(ΙΙ) mode and only the first half is set,
the network parameter settings need to be changed. In MELSECNET(ΙΙ) mode or MELSECNET(ΙΙ) composite
mode, if the second half settings exist, it is necessary to reset the B/W of each station's send range and set the
station inherent parameters.
Furthermore, when AnNCPUs, AnACPUs or AnSCPUs are part of the system, the program should be modified
because station inherent parameters cannot be set.
For precautions for the existing MELSECNET(ΙΙ) system configuration, refer to “Transition from
MELSEC-A/QnA (Large Type), AnS/QnAS (Small Type) Series to Q Series Handbook (Network Modules)”.

8.2 Upgrade to MELSECNET/H network system utilizing existing MELSECNET/B

twisted pair cable
When replacing A Series CPU with Q Series CPU in a MELSECNET/B data link system, the network
can be effortlessly updated to twisted bus type MELSECNET/H (PLC to PLC network) because the
existing MELSECNET/B twisted pair cable can be directly utilized. (New cable installation is not
required.)
The following is an example of replacing MELSECNET/B with twisted bus type MELSECNET/H (PLC to PLC
network) utilizing the existing twisted pair cable.
A. Instructions
(1) Replace all A Series CPUs found in the existing MELSECNET/B system with Q Series CPUs.
(2) Utilize the existing MELSECNET/B twisted pair cable.
(3) Modify the terminals of the network modules because the cable connection method has been changed from
screw terminal block type to spring clamp terminal block type.

refer to "Q corresponding MELSECNET/H Network System Reference Manual
(PLC to PLC network)": SH-080049.
83
Tip
• MELSECNET/H (twisted bus type) is compatible with Q Series CPUs only.
All A Series CPUs connected to the existing MELSECNET/B need to be upgraded to Q Series CPUs at once.
• MELSECNET/H (twisted bus type) is compatible with PLC to PLC network only. It is not compatible with
remote I/O network.
To replace MELSECNET/B with MELSECNET/H (remote I/O network), use optical loop system or coaxial
bus system.
Or, replace MELSECNET/B with MELSECNET/H (PLC to PLC network) and remote I/O stations with normal
stations. (Refer to Chapter 9)
• For details on Q Series CPU type to which MELSECNET/H network module (twisted bus type: QJ71NT11B)
can be mounted, number of mountable modules per CPU, and network parameter settings, refer to the
following manual.
"Q corresponding MELSECNET/H Network System Reference Manual (PLC to PLC network)" : SH-080049
• MELSECNET/H (twisted bus type) can use CC-Link cables. The maximum communication speed of the
network is 10 Mbps.

9. Replace MELSECNET containing a remote I/O station with MELSECNET/H

• Although MELSECNET systems may be a combination of local and remote I/O stations, two
separate networks are necessary when upgrading to Q Series. However, if the existing system
contains only a few remote I/O stations, only one network is needed if remote I/O stations are
replaced with normal (local) stations without changing the cable layout or adding new wiring.
• Even when the remote I/O stations are replaced with the normal stations, it is not required to
modify the control (master) station’s network related programs.
The following is an example of upgrading a MELSECNET(ΙΙ) system to MELSECNET/H by replacing both local
and remote I/O stations with normal stations.
A. Instructions
(1) Replace the MELSECNET(ΙΙ) master station with the MELSECNET/H control station, and the
MELSECNET(ΙΙ) local and remote I/O stations with the MELSECNET/H normal stations to maintain a single
network configuration. (This is because the controller network and remote I/O network cannot reside on a
single network.)
(2) Add a simple transfer program between LX/LY (link side device) and X/Y (actual I/O device) for the normal
station replaced from the remote I/O station. With this program, the normal station receives LY sent from
the control station by X and transfers it to actual output address Y; the normal station transfers input X to LY
so that the control station can receive it as X.
• MELSECNET(ΙΙ): I/O signal transfer between master station and remote station
- Master station input (X) <- Remote station input (X)
- Master station output (Y) -> Remote station output (Y)
• MELSECNET/H: I/O signal transfer between control station and normal station
- Control station input (X) <- Normal station output (Y)
- Control station output (Y) -> Normal station input (X)

10. Replace one of A Series stations with Q Series while retaining MELSECNET(ΙΙ)
• Using a local station data link module, the Q Series can directly connect to existing
MELSECNET(ΙΙ) network as a local station. Existing wiring can be utilized, and network parameter
modification is not required.
• Local station data link modules for optical fiber loop, coaxial loop, and MELSECNET/B are
provided to support all types of existing networks.
10.1 Replace A Series local station with Q Series

The following is an example of replacing one of A Series local stations with the Q Series.
A. Instructions
Replace the CPU and other modules on one of the A Series local stations with the Q Series, and mount the
MELSECNET(ΙΙ) local station data link module on the QA1S6�B extension base unit.

Tip
• Except for the local station replaced with the Q Series, modification to the system configuration and programs
are not required.
• Minimal setup is required, as network parameter settings (excluding link refresh setting) are automatically
detected by the local station data link module. FROM/TO instructions within sequence program (refresh
program) are required to enable send/receive cyclic data.
A sample program to enable send/receive of cyclic data can be created by "A/QnA -> Q conversion support
tool". (Refer to Chapter 17)
• If slots are left empty in the replacement Q Series CPU after connecting the A (Large Type) extension base
onto which the QA6�B extension base unit or QA conversion adapter QA6ADP is connected, the
MELSECNET(II), /B local station data link module can be connected using the A-A1S conversion adapter.
QA1S6�B or QA1S51B do not need to be additionally selected in this case.

10.2 Replace A Series master station with Q Series

The following is an example of replacing the A Series master station with Q Series.
A. Instructions
(1) Replace the CPU and other modules on the master station with Q Series while maintaining the existing
network, and mount the MELSECNET(ΙΙ) local station data link module on the QA1S6�B extension base unit.
(2) Since a Q Series station cannot be the master station, set Local station 1 as the master station, set the link
parameters, and change the station number of the rest of the local stations.
(3) Utilize the existing optical fiber cables.

Tip
• The data link module was designed for local stations and cannot be set as master station. For this reason, a
local station that is upgraded to Q Series cannot become the master station. Instead, one of the existing A
Series local stations should be set as the master station. The station numbers should be changed
accordingly, but the I/O address and parameters can remain the same.
• Minimal setup is required, as network parameter settings (excluding link refresh setting) are automatically
detected by the local station data link module. FROM/TO instructions within sequence program (refresh
program) are required to enable send/receive cyclic data.
• A sample program to enable send/receive of cyclic data can be created by "A/QnA -> Q conversion support
tool". (Refer to Chapter 17)
• For MELSECNET(Ⅱ), the station numbers must be assigned in the connecting order starting from the new
master station.
• The QA1S51B extension base without power supply module can be used for the local station data link
module mounting base.
Note that the voltage drop must be calculated if the extension cable is long.

C. Module wiring
The external wiring method is different between AD61/AD61S1 and QD62-H01/QD62-H02.
• AD61, AD61S1: Use a terminal block
• QD62-H01, QD62-H02: Use a connector
The following are replacement methods in which existing wiring are preserved.
(1) Replacement using a conversion adapter manufactured by Mitsubishi Electric Engineering Co., Ltd.
The existing modules' terminal blocks and wiring can be utilized. For replacement details, refer to the
following section.
• Chapter 3. Upgrade to Q Series using Q Series large type base unit and I/O modules
97
(2) Replacement using a connector/terminal block converter module

This replacement method is suitable when the Q Series large type base unit and conversion adapter
manufactured by Mitsubishi Electric Engineering Co., Ltd. cannot be used due to system configuration and
installation location restrictions.
Connect the input/output wires, which include solderless terminals, from the existing module to the
connector/terminal block converter module using a dedicated cable. This connection is not restricted by
differences in wiring size.
The following shows the wiring configuration when using a connector/terminal block converter module.

Tip
• The input filtering system and counting speed of replacement Q Series dedicated modules QD62-H01 and
QD62-H02 are the same as those of existing A Series high-speed counter modules AD61 and AD61S1.
High-speed counter modules can be replaced without being restrained by the specifications of existing pulse
generators (e.g. an encoder).
• AD61/AD61S1 and QD62-H01/QD62-H02 have different counting ranges. Modify the program in order to use
the same counting range as that of the module before replacement.
• AD61, AD61S1: 0 to 16,777,215 (24-bit unsigned binary)
• QD62-H01, QD62-H02: -2,147,483,648 to 2,147,483,647 (32-bit signed binary)
• The number of points occupied by the module changes from 32 to16 points, and thus the I/O signal
assignment (X/Y) also changes. Due to additional functions, the buffer memory addresses are changed and
program modification is necessary. Check the specification at "High-Speed Counter Module User's Manual":
SH-080036, and modify the program.

12. Replace DC input modules with 6 mA rated input current (QX41-S2, QX81-S2)
• When replacing with the existing A Series module, the rated input current of the DC input module
becomes smaller.
In some cases, the previous Q Series DC input modules were not able to detect input signals from
the external devices due to current insufficiency. Such issue can be solved by using DC input
modules with 6 mA rated input current (QX41-S2 and QX81-S2).
• The pin arrangement is identical to the existing Q Series DC input module (connector type). The
existing external wiring can be utilized to reduce replacement time.
A. Internal circuits when replacing existing A Series DC input modules

The following figures use AX41 and AX42 as an example of how to replace the existing A Series DC input
modules (AX41, AX42, AX81, AX82, A1SX41 and A1SX81). The internal circuits show the rated input currents
and provide countermeasures for current insufficiency.
* AX41 and AX42 have different common wiring, but the rated input current specifications and the
countermeasure of installing an external resistor are the same.

AX42 (large type A Series). Reconnect the external wire connectors after replacing the modules.
• Some of the specifications (rated input current etc.) differ between the AX42 and the A1SX42. Refer to
“Transition from MELSEC-A/QnA Large Type Series to AnS/Q2AS Small Type Series Handbook”
L(NA)08064ENG for details.

13.2 Use AnS Series module as spare parts for large type A Series computer link module
• If the computer link module malfunctions but large type A Series spare parts are not available, the
AnS Series computer link module can be installed on the A1ADP adapter and used as a
replacement, allowing the system to recover quickly.
• If a large type A Series computer link module is not available when the system requires an
additional module, the AnS Series computer link module can be installed on the A1ADP adapter
and used as a spare part.
The following is an example of replacing an A Series computer link module (AJ71UC24) with AnS Series
computer link modules (A1SJ71UC24-R2, A1SJ71UC24-R4) using the A1ADP adapters.
A. Instructions
(1) Remove the AJ71UC24 from the base unit, and mount the A1SJ71UC24-R2 and A1SJ71UC24-R4 on the
base unit using the A1ADP adapters.
Note: The large type A Series computer link modules have two channels (RS232C and RS422), whereas
the AnS Series computer link modules only have one. Therefore, if two channels are used, two
modules are needed.
(2) A program modification is not required if:
• The AnS module set to the No-protocol mode is mounted on the same slot as the existing module.
• The AnS module set to the Dedicated protocol mode is mounted on the empty slot.
(This is because the No-protocol mode requires a transmission program but the Dedicated protocol
mode does not.)

Tip
• The AJ71UC24 and A1SJ71UC24-R2/A1SJ71UC24-R4 have the same buffer memory address and
transmission X/Y address assignment for the No-protocol mode. Therefore, it is not required to modify the
program if the module set to the No-protocol mode is mounted on the same slot as the existing module.
• The module set to the Dedicated protocol mode does not require a programmable controller program. Also,
the external device connected to this module can communicate regardless of its slot address-changing the
address does not affect communication.
However, when the “On-demand function” is used, it is required to modify the program due to changes in the
designated address for the “TO instruction” and handshake X/Y address.

14. Precautions for utilizing ACPU programs in QCPU

The following are precautions when converting ACPU programs to QCPU using "Change PLC type":
• The instruction format may change after executing “Change PLC type”.
Also, while ACPU instructions that use accumulators (A0 and A1) do not specify device name and device
number, QCPU instructions do.
• Modification of the program is needed when instruction specifications are different.
• Instructions are replaced with SM1255 when an eligible instruction is available upon execution of "Change
PLC type", but is unusable due to specification differences.
There are several inquiries regarding conversion of instructions, their specifications, and corrective actions after
conversion. This chapter explains the most frequently asked questions when converting ACPU programs to
QCPU programs.
A. Peripheral devices using existing A (Large Type) and A0J2 Series CPU program
The following CPU types are not compatible with GX Developer, so the PC type must be changed to GX
Developer compatible CPU types with the following instructions before the programs can be used.
• GX Developer incompatible CPU
AnCPU (including CPU with link function)
A3HCPU (including CPU with link function)
A3MCPU (including CPU with link function)
A0J2CPU (including CPU with link function)
• Instructions
1) For A6GPP(SW�GP-GPPA)
1. Using A6GPP(SW�GP-GPPA), read the program from the existing CPU with “Read from PC”.
m
2. Change PC type to the GX Developer compatible A Series CPU on hand.
m
3. Write the program with revised PC type into the GX Developer compatible A Series CPU on hand.
m
4. Using “Read from PC”, read the program from ACPU that was written with GX Developer.
m
5. After replacing with GX Developer, change the PC type to QCPU type.
2) For MS-DOS compatible GPPA software (SW�IVD/NX-GPPA)

1. Using the MS-DOS compatible GPPA software, read the program from the existing CPU with “Read from PC”.
m
2. Change PC type to the GX Developer compatible A Series CPU.
m

14.1 Replace instructions with different QCPU instruction format

(excluding AnACPU/AnUCPU dedicated instructions)
14.1.1 Instructions that use accumulators (A0, A1)
Some QCPU operation processing instructions are different from their corresponding ACPU instructions in
format.
This section explains the instructions that have different specified formats.
Frequently asked questions regarding the conversion of ACPU to QCPU program
(Inquiry example)
1. Instructions with different format from that of ACPU instructions are used when
upgrading to QCPU. Is further program modification necessary?
2. The devices "SD718 and SD719", which were not used in ACPU, are automatically part
of the QCPU instructions after replacement. What are these devices for? Is operation
affected by these devices?
3. "Change PLC type" executes a direct conversion of several ACPU instructions, such as
assignment and saving of operation data, but the instruction format remains similar to
that of ACPU instructions. Is it possible to further simplify the QCPU instructions using a
similar method?
(Answer)
ACPU instructions that use accumulators (A0 and A1) have different formats when
converted to QCPU instructions. These accumulators are replaced by devices SD718 and
SD719.
Therefore, the same operation as in ACPU is executed even if the instruction format is
different and SD718 and SD719 are used.
In addition, a group of multiple instructions, such as instructions to transfer data to the
ACPU accumulators (A0 and A1), can be converted to QCPU instructions and further
modified to simplify the program and reduce the number of steps.
A. Instructions that use accumulators (A0 and A1)

(1) ACPU
Instructions that use accumulators (A0 and A1) can execute operations without explicitly specifying A0 and
A1 as the source and destination device. Also, the operation result is stored in the accumulators A0 and
A1 without specifying the device in which it is stored in.
(2) QCPU
QCPU instructions need to specify a source and destination device.
111
B. ACPU to QCPU instruction replacement

Replacing ACPU program with QCPU program using “Change PLC type” converts ACPU instructions into
QCPU instructions. Therefore, even if the accumulators A0 and A1 are not explicitly specified in the ACPU
program, the devices SD718 and SD719 will automatically take over the accumulators’ functionalities in the
QCPU program.
However, if A0 and A1 are explicitly described in the ACPU program, the devices SD718 and SD719 will
directly replace the accumulators.
The program converted through “Change PLC type” will execute normally and modifications are not necessary.
C. Changing to QCPU instruction format

The automatically converted programs will execute without problems. However, modifying the instructions into
QCPU format will significantly simplify the program and reduce the number of steps.

14.1.2 ASCII code conversion instruction "ASC"

ASCII code conversion instruction is replaced with SM1255 because it is an unconvertible instruction and its
specification is incompatible with QCPU. Modification in accordance with the specifications is needed. (For Basic
model QCPUs, it is replaced with SM999.)
This section explains replacement of the ASCII code conversion instruction "ASC".
(Inquiry example)
1. Instead of the $MOV instruction, which has similar functionality, the ASCII code
conversion instruction "ASC" is replaced with SM1255 as an unconvertible instruction.
Are the $MOV and ASC instructions the same?
2. The Transition Handbook (Fundamentals) lists $MOV as a conversion candidate for the
ASC instruction. Are there any precautions in this modification?
(Answer)
The ACPU instruction, ASC, and the $MOV instruction in QCPU are slightly different. For
this reason, ASC is replaced with SM1255 as an unconvertible instruction. Check the
specifications and functions before changing to the $MOV instruction.
A. Specifications of ASCII codes conversion instruction

The following are the ASCII code conversion instruction specifications for ACPU and QCPU
(1) ACPU (Instruction: ASC)
• Converts up to 8 characters.
• When there are 7 characters or less, it is converted and stored as 8 characters (4 words).
(space (20H) is stored until reaching 8 characters.)
• “P” is not appended to the instruction, however, the operation is only executed when the execution
condition pulses ON.
(2) QCPU (Instruction: $MOV)
• Converts up to 32 characters.
• Device points of storage destination may change (number of characters + 1 byte (rounded up in units of
word)).
• Execute the operation as long as the execution condition is ON.
(To execute the operation only when the condition for instruction execution pulses ON, change the
instruction to “$MOVP”.)
115
B. Occupied device points

The ACPU instruction, ASC, occupies 4 words. The number of device points occupied by the QCPU
instruction, $MOV, may change according to the number of characters+1 byte.
When replacing an ASC instruction that specifies 8 characters with the QCPU $MOV instruction, the number of
occupied points increases because the stored ASCII code occupies 4 devices + 1 word (delimiter "00H"). If the
additional device was being used for other purposes, its content will clear to "0000H".
Modification is necessary when the devices used by the ASC instruction +1 are used for other operations.
(Example of stored data)

(1) 5 characters
ACPU: (ASC 1234A D0)
QCPU: ($MOV “1234A” D0)
Device ACPU QCPU
D0 3231 (H) 3231 (H)
D1 3433 (H) 3433 (H)
D2 2041 (H) 0041 (H)
D3 2020 (H) No change
D4 No change No change
(2) 8 characters
ACPU: (ASC 1234ABCD D0)
QCPU: ($MOV “1234ABCD” D0)
Device ACPU QCPU
D0 3231 (H) 3231 (H)
D1 3433 (H) 3433 (H)
D2 4241 (H) 4241 (H)
D3 4443 (H) 4443 (H)
D4 No change 0000 (H)
116
C. Program replacement example

ACPU "ASC" instruction program
* Up to 8 characters of ASCII codes are stored in D0 to D3.
M0
0 ASC ABCD1234 D0
* Up to 8 characters of ASCII codes are stored in D10 to D13.

* 5 characters are specified. Higher byte of D12: 20H, D13: 2020H.
M1
14 ASC XYZ78 D10
28 END

(Unconvertible instructions are replaced with SM1255)
* Conversion to character string instruction, ASC, is unconvertible and replaced with "SM1255".
M0
0 SM1255
* Conversion to character string instruction, ASC, is unconvertible and replaced with "SM1255".
M1
3 SM1255
6 END
Modified QCPU program using "$MOV" instruction

8 characters are specified, and ASCII codes are stored in D0 to D3.
Since “00H” is added after the last character, “0000H” is stored in D4.
When the program is replaced, make sure that D4 is not used elsewhere for other purposes.
M0
0 $MOVP “ABCD1234” D0
Stores ASCII code of up to 32 characters in D10.

The last occupied device is D25 when 32 characters are specified.
However, “0000H” is stored in D26 because “00H” is added after the last character.
M1
103 $MOVP “1234567890123456” D10

14.2 Replace AnACPU/AnUCPU dedicated instructions

AnACPU/AnUCPU dedicated instructions can be converted into QCPU instruction format. This section explains
the replacement of AnACPU/AnUCPU dedicated instructions.
(Inquiry example)
Several AnACPU/AnUCPU dedicated instructions were used in the program. However,
converting the program to QCPU format reduced them to just one instruction. Can this
program be executed as it is?
(Answer)
Replacing AnACPU/AnUCPU dedicated instructions with QCPU instructions changes and
simplifies the instruction format. Further modification of the program is not necessary.
(Inquiry example)
Can the AnACPU/AnUCPU dedicated instructions for special function modules also be
replaced?
(Answer)
AnACPU/AnUCPU special function modules and QCPU intelligent function modules have
different functions, specifications, number of occupied points, etc. The AnACPU/AnUCPU
special function module instructions cannot access the QCPU, therefore, they are replaced
with SM1255 as unconvertible instructions.
Modify the program according to the functions and specifications of QCPU intelligent
function modules. Instructions for extended file registers and data link are also replaced
with SM1255. Please modify the instructions in accordance with QCPU functions and
specifications.
118
A. Representations of dedicated instruction

The QCPU unifies AnACPU/AnUCPU dedicated instructions- LEDA, LEDB, LEDC, SUB, and LEDR- into one
single instruction, which has the same format as the basic and application instructions. Instructions that do
not have a corresponding QCPU instruction are replaced with "OUT SM1255". Replace or delete the
instructions that have been converted to "OUT SM1255".

14.3 Use index register as a 32-bit (2-word) device

After replacing ACPU instructions that use index registers, review and modify the programs because the A
Series and Q Series index registers differ in specifications (Z and V are for ACPU, and Z0 to Z15 are for QCPU).
The following are precautions for converting ACPU instructions that use index registers.
(Inquiry example)
1. Device modification using index registers resulted in different Z and V device numbers.
Which QCPU devices are the Z and V devices in ACPU replaced with?
2. Index registers were used as 32-bit devices (2 words) in ACPU. However, when
upgrading to QCPU, the values of the index registers used for other purposes were
overwritten.
Can index registers be used as 32-bit devices (2 words) in QCPU?
(Answer)
The ACPU index registers, Z, Z1 to Z6, V, and V1 to V6, are replaced with Z0 to Z15. If the
index registers were used as 16-bit devices (1 word) in ACPU, the device numbers will
change once upgraded to QCPU. However, modification of the program is unnecessary.
If the index registers were used as 32-bit devices (2 words) in ACPU, the combination of Z
and V converts to Zn and Zn+1 in QCPU. The index register numbers are different after
replacement and modification of the program is necessary.
122
A. Replacing index register

"Z, Z1 to Z6, V, V1 to V6" and "Z0 to Z15" are used as index register for the ACPU and QCPU,
respectively. Therefore, their specifications differ.
"V" is used as edge relay for the QCPU. This device is used to store the PLS/PLF information of the contacts
found at the start of the ladder block.
The following table shows how the index registers should be replaced when changing ACPU programs to
QCPU programs using "Change PLC type".
ACPU QCPU
Z Z0
Z1 to Z6 Z1 to Z6
V Z7
V1 to V6 Z8 to Z13
Tip
When indexing timer/counter contact instructions, such as “LD T0”, the index register limitations do not apply to
AnA/AnUCPU.
Due to the specifications, only index registers Z0 and Z1 can be used to index timer/counter contact
instructions in QCPU.
If the existing AnA/AnUCPU program uses index registers other than Z and Z1, the instructions are
unconvertible and are replaced with SM1255. In this case, it is necessary to modify the program.
B. Index register 32-bit specification

When using index registers in 32-bit instructions in ACPU, Z register is the low- order 16 bits and the V
register, with the same number as Z, is the high-order 16 bits.
Alternatively, the QCPU treats Zn and Zn + 1 as the low-order and high-order 16 bits respectively.
The index registers should be corrected if "Change PLC type" is performed on a program that includes 32-bit
index registers.
The following is an example of instructions that have 32-bit operation results.
Instruction ACPU QCPU

V1, Z1 Z2, Z1
DMOV D0 Z1
(High order) (Low order) (High order) (Low order)
Z1(Quotient) Z1(Quotient)
/ D0 D1 Z1
V1(Remainder) Z2(Remainder
When converting an ACPU program to QCPU using "Change PLC type", the operation result may be stored
to an unintended index register number.
123

(1) When using index register as 16-bit (1-word) data
The index register numbers will change after converting the ACPU program to QCPU, but it is not necessary
to modify the program.

15. Utilize SFC programs (Replace MELSAP-ΙΙ with MELSAP3)
15. Utilize SFC programs (replace MELSAP-ΙΙ with MELSAP3)

• The SFC program (MELSAP-ΙΙ) created in ACPU can be converted to QCPU SFC program
(MELSAP3) through "Change PLC type" in GX Developer. This program can be used without
further modifications.
• SFC program (MELSAP3) has the same specifications in QnACPU as in QCPU. Therefore, it is not
necessary to modify the program after executing "Change PLC type" in GX Developer.
• SFC programs (MELSAP-ΙΙ and MELSAP3) created with MS-DOS-compatible programming
software ((SW�IVD-GPPA and SW�IVD-GPPQ) can be converted and utilized after being imported
to GX Developer.
This chapter explains how to replace SFC programs (MELSAP-ΙΙ) created in ACPU with SFC programs
(MELSAP3) for QCPU and the necessary modifications after the replacement.
126
A. Operation for utilizing SFC program
Procedure 1: Changing programmable controller type in GX Developer
"Change PLC type" is a function that changes the target programmable controller type of the data being read
through GX Developer. The sequence programs are also automatically converted to comply with the target
programmable controller. However, instructions that cannot convert automatically are replaced with the
instructions shown below.
• High Performance Model QCPU: OUT SM1255
• Basic Model QCPU: OUT SM999
Search for these "OUT" instructions or SM1255/SM999 devices and manually modify the converted programs.
Additionally, intelligent function modules and network modules may require program and parameter
modifications.

B. Precautions for replacing MELSAP-II with MELSAP3

The basic operation of the MELSAP3 is the same as the MELSAP-ΙΙ, but the specifications are partially
different.
This section provides the precautions for the replacement.
(1) Starting SFC program
The SFC program can be started by using the special relay for starting/stopping the SFC program.
The special relay used for starting/stopping SFC programs changes according to the programmable
controller type.

In this method, the existing external wiring needs
to be modified for building block type I/O module.
The following are the precautions.
• The wire size compatible with Q Series I/O
module (terminal block type) is 0.75 mm2.
Existing wire larger than this specified size may
not be utilized.
• Since the Q Series terminal block type I/O
module only has 16 I/O points, the existing
A0J2-E56�� will require at least 4 modules (2
input and 2 output). Therefore, depending on
the number of existing modules, they might not
fit on a single base unit.
• The I/O address assignment changes when
replacing A0J2-E28��, A0J2-E32�, or
A0J2-E24�.
Check the precautions before performing the
replacement.

4 How do I install the CPU? There are 3 types of installation methods
depending on the size and depth of the control
panel.
• Stackable type
When there is enough depth but no extra
installation area.
• Flat mounting type
When there is extra space above the existing
system but not enough depth.
• Standalone type
When there is no extra installation area nor
enough depth.
Select an appropriate installation method
according to the space of the control panel.
Note that when AnSCPU is used to replace the
CPU, only the standalone type can be selected.
