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 controlling (changing data) 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 other controls for the running programmable controller (program modification and operating status

change (status control)), 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.

WARNING

Design Precautions

●

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 mechanical zero return of the positioning function is controlled based on two parameters, zero
return direction and zero return speed, and deceleration is started when the near-point dog is turned
on. Therefore, if the zero return direction is set incorrectly, the positioning function may continue the
operation without deceleration. Configure an interlock circuit for prevention of mechanical damage on the
outside of the programmable controller.

(3) When the CPU module detects an error during operation of the positioning function, the function will

decelerate and stop.

(4) The programmable controller stops its operation upon detection of the following status, and the output

status of the system will be as shown below.

• When the overcurrent or overvoltage protection of the power supply module is activated, all outputs

will be turned off.

• When the CPU module detects an error such as a watchdog timer error by the self-diagnostic

function, all outputs will be 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 LOADING AND INSTALLATION in the LCPU User's Manual (Hardware Design,
Maintenance and Inspection).

(5) Outputs may remain on or off due to a failure of a transistor on an output circuit. Configure an external

circuit for monitoring output signals that could cause a serious accident.

●

In an output circuit, 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

1.1 Comparison of A/QnA (Large Type) Series and Q Series base unit mounting area

Comparison of base mounting area

1.

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 (Large Type) 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 (Large Type) Series.
The following example shows a comparison of the mounting areas when the A/QnA (Large Type) 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.

• Q38B main base unit/Q68B 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.

1.3 Comparison of AnS/QnAS (Small Type) Series and L Series mounting area

1.3 Comparison of AnS/QnAS (Small Type) Series and L Series mounting area

The L Series modules are designed to be installed directly on the DIN rails. The modules can be
mounted freely according to the in-panel space.
When replacing AnS/QnAS (Small Type) Series modules with L Series, examine the mounting method
in consideration of the in-panel space.

Solution and Benefit

(1) Using the "AnS to L Series conversion adapter" (manufactured by Mitsubishi Electric

Engineering Co., Ltd.), the module to be mounted has a wiring connector incompatible with
the terminal block of the terminal block type module can fit into the existing space without
changing the wiring.

(2) The number of modules to be newly mounted can be reduced by using various built-in

functions of the CPU.

2.1 Replace A/QnA (Large Type) Series with Q Series

2.1.1 Install terminal block converter module and terminal module externally
(1) Replace 32-point terminal block type module using connector/terminal block converter module

Solution and Benefit

• 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 (Large Type) Series system that contains 32-point terminal
block type input modules (AX41).

● Instructions

Replace AX41 with QX41, and connect the connector/terminal block converter module.
If QX40 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.

2.1 Replace A/QnA (Large Type) Series with Q Series

(2) Replace 32-point contact output type module using "relay terminal module"

Solution and Benefit

• Using the relay terminal modules, a large type A (Large Type) 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 (Large Type) Series 32-point contact output module AY13: Max. 2 mm
Relay terminal module: Max. 1.25 mm
Q Series 16-point contact output module QY10: Max. 0.75 mm

• 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.

● 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.

(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.

2.1 Replace A/QnA (Large Type) Series with Q Series

(2) Upgrade to Q Series modules using Q Series large type base unit

Solution and Benefit

• Unlike the QA6�B extension base unit, which is used to directly mount existing A (Large Type)
Series I/O modules for a gradual upgrade, the Q Series large type base unit, I/O module, and
conversion adapter (upgrade tool) (manufactured by Mitsubishi Electric Engineering Co., Ltd.)
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 (Large Type) 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 (Large Type) Series, eliminating concerns about compatibility with the connected external
devices.

The following is an example of upgrading an A (Large Type) Series system to the Q Series using the Q Series
large type base units, I/O modules, and conversion adapters.

● 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 (manufactured by

Mitsubishi Electric Engineering Co., Ltd.) to replace the existing module with standard Q Series I/O module.

(1) Utilize AnS/QnAS (Small Type) module replacement upgrade tool

Solution and Benefit

• The MELSEC-AnS Series/MELSEC-Q Series upgrade tool conversion adapter (manufactured by
Mitsubishi Electric Engineering Co., Ltd.) reduces wiring time as the AnS/QnAS (Small Type)
Series 16-point terminal block type module’s terminal block can be used without modification.

• New mounting holes do not need to be drilled as the MELSEC-AnS Series/MELSEC-Q Series
upgrade tool base adapter (manufactured by Mitsubishi Electric Engineering Co., Ltd.) can be
mounted with the existing main/extension base unit mounting holes.

MELSEC-AnS Series/MELSEC-Q Series upgrade tool
(manufactured by Mitsubishi Electric Engineering Co., Ltd.)

The MELSEC-AnS Series/MELSEC-Q Series upgrade tool (manufactured by Mitsubishi Electric Engineering
Co., Ltd.) is comprised of the base adapter and conversion adapter. This tool can be used with just the base
adapter or conversion adapter.

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.
Transition from MELSEC-A/QnA (Large Type) Series to Q Series Handbook (Fundamentals) L(NA)08043
MELSEC-A/QnA (Large), AnS/QnAS (Small) Transition Examples L08121 (-B and higher)
Note that the CPU/base unit integrated CPU type cannot be used with the Q Series large extension base
unit.

In this case, secure wiring space by leaving empty slots in between modules. For example, mount modules
on slot No. 0, 2, 4, 6, 8, and leave slot No. 1, 3, 5, 7 empty. Mount a blank cover QG60 on the empty slots.
If there are not enough slots, consider using the AnS size version Q Series large type base unit.

*9: Applies when using replacing the existing A (Small Type) module with the two Q Series modules, and using

the existing wiring terminal block with the conversion adapter.

2.4 Replace A0J2 with Q Series

A0J2 upgrade tool

■ A0J2 renewal tool features

The A0J2 renewal tool is used to replace existing A0J2(H) systems with the Q Series.
It consists of an interface module where the existing wired terminal block can be mounted and a base
adapter which enables utilization of the existing installation holes, etc.
A variety of installation methods are available to fit the installation space.

■ Interface module features

The interface module has DC to relay output conversion and AC to DC input conversion functions. Hence,
replacement is possible using the interface module along with Q Series connector type DC I/O modules.
Dedicated cables are used to connect the interface module to Q Series I/O modules.

• Installation types

(1) Stackable type

• Existing mounting holes can be used.

• Suitable when there is enough depth.

(A depth of 195 mm (when one interface module

is stacked)/236 mm (when two interface modules
are stacked) or more is required.)

(2) Flat mounting type

• Existing mounting holes can be used. However,

enough depth and space above the existing
modules are required.

(A space of 62 mm + 30 mm (for heat dissipation)

is required above existing modules)

(A depth of 158mm is required.)

• The required depth is less than that of the

stackable type.

(3) Standalone type

• Although space to install the main base unit

separately is needed, a base unit with a larger
number of I/O slots can be installed. Suitable
when there is not enough space in the existing
A0J2(H).

W = 189 mm (for Q33B: 3 I/O slots),

245 mm (for Q35B: 5 I/O slots),
328 mm (for Q38B: 8 I/O slots)

2.4 Replace A0J2 with Q Series

2.4.1 Replace A0J2(H) systems with Q Series using A0J2 upgrade tool

Solution and Benefit

• Existing A0J2 I/O wiring can be mounted on the A0J2 upgrade tool without modification.

• The A0J2 upgrade 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 upgrade 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 upgrade 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 upgrade tool.

● 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, and program modifications can be avoided.

(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.

Tip

• MELSECNET/MINI twisted pair cables must be replaced with CC-Link dedicated cables.

• CC-Link I/O modules and A0J2 upgrade tools (interface modules) require 24 V DC power supply in addition

to power supply for control. Prepare a 24 V DC power supply separately.

• When using the stackable type renewal tool as shown in the example, make sure there is enough depth.

(Required depth: 120 mm or more)
The mounting plate for CC-Link I/O modules is sold separately.

• Also the CPU can be replaced with LCPU.
When it is replaced with L Series, the CC-Link master module LJ61BT11 or the built-in CC-Link function of

the CPU will be used.
The remote module is common to Q Series and L Series.

1. The extension base unit equipped with QA1S6ADP must be installed in the first extension stage.
Since QA1S6ADP does not have an extension cable connector (OUT), it cannot be connected to the base

unit in the second extension stage or higher.

Therefore, when QA1S6ADP is used, the system consists of 2 base units, Q Series main base unit and

AnS extension base unit equipped with QA1S6ADP.

To replace only the CPU with Q Series, it is required to use the QA1S extension base unit. Refer to Item

3.2.1.

2. When the existing A/AnS Series modules are used, the program can be used without changing the
existing I/O addresses through I/O assignment by parameters.

For the detailed procedures for setting the I/O addresses through I/O assignment, refer to Section 3.3.

3. The AnS extension base unit equipped with QA1S6ADP can be used with a high performance model
QCPU or universal model QCPU (the first 5 digits of the serial number must be "13102" or later).

The modules which can be installed in the AnS extension base unit equipped with QA1S6ADP are the

same as those installed in the QA1S extension base unit. For details, refer to "Transition from MELSEC­AnS/QnAS (Small Type) Series to Q Series Handbook (Fundamentals)."

3.3 Utilize existing A (Large Type) and AnS (Small Type) modules without changing I/O addresses

3.3 Utilize existing A (Large Type) and AnS (Small Type) modules without
changing I/O addresses

Solution and Benefit

• The I/O addresses do not need to be changed when reutilizing existing A (Large Type) and AnS

(Small Type) modules with Q Series CPU and mounting the modules on QA6�B/A6�B＋QA6ADP
or QA1S6�B. 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.

(1) 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.

4.1 Replace MELSECNET(ΙΙ) with MELSECNET/10

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.
If the second half of settings have been made in the MELSECNET ΙΙ mode or MELSECNET ΙΙ composite
mode, the B and W station send range must be reset, and the station's inherent parameters must be set, etc.
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 regarding 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)".

4.1 Replace MELSECNET(ΙΙ) with MELSECNET/10

4.1.2 Upgrade to MELSECNET/H network system utilizing existing MELSECNET/B twisted pair cable

Solution and Benefit

When replacing A (Large Type) 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.

● 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.

4.1 Replace MELSECNET(ΙΙ) with MELSECNET/10

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 Section 4.3)

• 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.

4.2 Replace one of A Series stations with Q Series while retaining MELSECNET(ΙΙ)

4.2.1 Replace A Series local station with Q Series

Solution and Benefit

(1) Using a local station data link module, the Q Series can directly connect to existing

MELSECNET(II) network as a local station. When replacing A(Large type/Small type)Series CPU
with Q Series CPU, existing wiring can be utilized, and network parameter modification is not
required.

(2) MELSECNET(II) local station data link modules for optical fiber loop, coaxial loop, and

MELSECNET/B are provided to support all types of existing networks.

The following is an example of replacing one of A Series local stations with the Q Series.

● Instructions

Replace the CPU and other modules on one of the A Series local stations with the Q Series, and mount the
MELSECNET(II) or MELSECNET/B local station data link module on the QA1S6oB extension base unit.

Tip

1. Except for the local station replaced with the Q Series, modification to the system configuration and
programs are not required.

2. 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" (which can be downloaded from the MELFANSweb). (Refer to Section 9.2)

3. 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.

Tip

1. 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.

2. 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" (which can be downloaded from the MELFANSweb). (Refer to Section 9.2)

3. For MELSECNET(II), the station numbers must be assigned in the connecting order starting from the new
master station.

4. 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.

4.3 Replace MELSECNET containing a remote I/O station with MELSECNET/H

4.3 Replace MELSECNET containing a remote I/O station with MELSECNET/H

Solution and Benefit

• 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.

● 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)

4.4 Gradual replacement of MELSECNET/10 Remote I/O Net

4.4 Gradual replacement of MELSECNET/10 Remote I/O Net

(Utilize QJ72LP25-25(G), QJ72BR15 (MELSECNET/10 mode))

Solution and Benefit

Replace the remote I/O station only in a station unit to the Q Series remote I/O station while utilizing
the current AnU(S)CPU/QnA(S)CPU master station. This allows gradual replacement of the network
to the Q Series.

Tip

• Replace the MELSECNET/10 mode master station CPU

The Q Series master station cannot be connected to the A/AnS remote I/O station. When replacing the
current master station with the Q Series in the final stage, all remote I/O stations must be Q Series stations.

• Replace the A Series special module with the Q Series intelligent function module

The Q Series intelligent function module's buffer memory can be read/written using the current A/QnA Series
dedicated instructions.
The sequence program must be revised as the number of occupied points, I/O signals and buffer memory
address may change.

• Replace master station CPU to Q Series in final step

(a) Using only I/O module

The network can be shifted to the MELSECNET/H remote I/O network by changing the mode switch
setting from 8 to 0. There is no need to change the program.

(b) Using the intelligent function module

• The network can be shifted to the MELSECNET/H remote I/O network by changing the mode switch

setting from 8 to 0.

• The Q Series intelligent function module's buffer memory read/write instructions must be changed to Q

Series link dedicated instructions. Refer to the "Q Series Compatible MELSECNET/H Remote I/O
module reference Manual (MELSECNET/10 Mode Section)" for details on the dedicated instructions.

Note:

This replacement is intended for an existing MELSECNET/10 remote I/O network system.
Replacement from the MELSECNET (II, II mixed) or MELSECNET/B data link system is not supported.
