[Design Precautions]
WARNING
● When controlling a running programmable controller (data modification) by connecting a peripheral
to a CPU module or connecting a personal computer to an intelligent/special function module, create
an interlock circuit on the sequence program so that the whole system will operate safely all the time.
Also, before performing other controls (e.g. program modification, operating status change (status
control)), read this manual carefully and ensure the safety.
Especially, in the control from an external device to a programmable controller in a remote location,
some programmable-controller-side problems cannot be resolved immediately due to a data
communication failure.
To prevent this, establish corrective procedures for communication failure between the external
device and the programmable controller CPU, as well as creating an interlock circuit on the
sequence program.

● In the case of a data link error, the operation status of a faulty station is as shown below. Using the
communication status information, create an interlock circuit on the sequence program for the
system to operate safely.
Incorrect output or malfunction can lead to an accident.
(1) All of general-purpose inputs from this module turn OFF.
(2) All of general-purpose outputs from this module turn OFF.

● Depending on the module failure, inputs and outputs may turn ON or OFF incorrectly.
For I/O signals that may cause a serious accident, provide an external monitoring circuit.

A-1
 CAUTION
● Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.

● Always use the data link terminal block for connection of a CC-Link dedicated cable to a master
module.
Care must be taken because, if the cable is incorrectly inserted into the general-purpose I/O terminal
block instead of the data link terminal block, the module will break down.

[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets the general specifications given in
this manual.
Using this programmable controller in an environment outside the range of the general specifications
could result in electric shock, fire, erroneous operation, and damage to or deterioration of the
product.

● Using a tool specified by the manufacturer, correctly press, crimp, or solder the wires of the
connector and securely connect the connector to the module.
Incomplete connection may cause a short circuit and/or malfunctions.

● Do not directly touch the module's conductive parts or electronic components.

Touching the conductive parts could cause an operation failure or give damage to the module.

● Securely fix the module with the DIN rail or installation screws. Installation screws must be tightened
within the specified torque range.
A loose screw may cause a drop of the module, short circuit or malfunction.
Overtightening may damage the screw, resulting in a drop of the module or a short circuit.

● Completely connect each cable connector to each receptacle.

Incomplete connection may cause a malfunction due to poor contact.

A-2
[Wiring Precautions]
CAUTION
● Be sure to shut off all phases of the external power supply used by the system before installation or
wiring.
Failure to do so may cause an electric shock, damage to the product and/or malfunctions.

● Attach the terminal cover to the product before energizing and operating the system after installation
or wiring.
Failure to do so may cause an electric shock.

● Be sure to ground the FG terminals and LG terminals to the protective ground conductor.
Failure to do so may result in malfunctions.

A-3
[Wiring Precautions]
CAUTION
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.

● When wiring in the programmable controller, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout.
Connecting a power supply that is different from the rating or incorrectly wiring the product could
result in fire or damage.

● Tighten the terminal screws with the specified torque.

If the terminal screws are loose, it could result in short circuits, fire, or erroneous operation.
Overtightening a terminal screw may damage the screw, resulting in a short circuit or malfunction.

● Be sure there are no foreign substances such as sawdust or wiring debris inside the module.
Such debris could cause fires, damage, or erroneous operation.

● Place the connection wires and cables in a duct or clamp them.

If not, dangling cables may swing or inadvertently be pulled, resulting in damage to the module and/
or cables or malfunctions due to poor cable connection.

● Do not install the control cable(s) together with the communication cable(s).
Doing so may cause malfunctions due to noise.

● When disconnecting a communication or power cable from the module, do not pull it by holding the
cable part.
For a cable with connector, hold the connector and disconnect it from the module.
For a cable without connector, loosen the connector screw and disconnect the cable.
Pulling the cable that is still connected to the module may damage the module and/or cable and
cause malfunctions due to poor cable connection.

● Make sure that the interface type is correct before connecting the cable.
Do not connect a cable to a module that has different interface specification.
Doing so will cause a module failure.

● Using a tool specified by the manufacturer, correctly press, crimp, or solder the wires of the
connector and securely connect the connector to the module.
Failure to do so may result in a malfunction or failure of the module.

A-4
[Startup·Maintenance Precautions]

 1 OVERVIEW

(a) The send/receive buffer communication function allows effective use of the
transmission path.
By using this function, only the necessary data of the specified size can be sent/
received at any given timing.
This can improve the transmission line efficiency (link scan time) because
unnecessary data will not be transferred.

(b) The buffer memory auto-refresh function makes communication easier.

The buffer memories of the AJ65BT-R2N and master station are refreshed
automatically at a timing set in the AJ65BT-R2N.
The buffer memory auto-refresh function eliminates the need for creating
programs for reading/writing data between the AJ65BT-R2N and master station.
Data can be read or written with intelligent function module devices or FROM/TO
instructions, which makes programming easier.

(3) Precautions for use of the MELSOFT connection function

(a) Buffer memory access method in MELSOFT connection mode
Since the buffer memory auto-refresh function does not work in MELSOFT
connection mode, the auto-refresh buffer of the master station is not refreshed
with data in the AJ65BT-R2N buffer memory.
In addition, only reading the AJ65BT-R2N buffer memory (e.g. RIRD instruction) is
allowed.
Writing (e.g. RIWT instruction) will cause an error (BB41H: Command error).

 4 FUNCTIONS

(b) Precautions for online operation

1) An online operation from an external device via the AJ65BT-R2N must be
started after the L RUN LED of the AJ65BT-R2N turns ON.
No online operations can be performed while the L RUN LED is OFF.
Upon completion of the initial communication on the CC-Link, the L RUN LED
of the AJ65BT-R2N turns ON.
2) When accessing a programmable controller CPU through the following CC-
Link system, the access time is approx. 40 seconds.

Table 4.1 Standard access time

Item Description
CC-Link system Connection of master station and AJ65BT-R2N only

•CC-Link system: 10Mbps
Data transmission speed •Between AJ65BT-R2N and external device: 19200bps
(Using the engineering tool)
Access Reading or writing sequence program (10k steps)

When accessing a programmable controller CPU on a heterogeneous

network, a delay may occur depending on the number of accessing stations
and access conditions.

(c) Precautions for using the AJ61BT11 or A1SJ61BT11

When using the AJ61BT11 or A1SJ61BT11, a "communication error" can occur in
the external device connected to the AJ65BT-R2N in rare cases.
Check the following and take corrective actions.
1) Cause
The programmable controller CPU may have frequently executed FROM/TO
instructions to the buffer memory of the AJ61BT11 or A1SJ61BT11.
• Access from a programmable controller CPU takes priority.
Therefore, frequent access to the buffer memory will not only increase the
scan time of the programmable controller CPU but also cause a
"communication error" due to a delay in the processing of the AJ61BT11
or A1SJ61BT11.
2) Corrective action
In the case of access to the buffer memory of the AJ61BT11 or A1SJ61BT11,
add a contact to the FROM/TO instruction so that the input signal (XnC) to the
module is OFF.
(XnC: FROM/TO enable/disable signal, when XnC is OFF, execution of the
FROM/TO instruction is enabled.)
By adding the contact by which XnC remains OFF, data communication can be
performed normally.

5.6.1 CC-Link dedicated cable connection method

The following describes the connection method of a CC-Link dedicated cable.

CAUTION
● Be sure to shut off all phases of the external power supply used by the system before installation or
wiring.
Failure to do so may cause an electric shock or damage to the product.
● Attach the terminal cover to the product before energizing and operating the system after installation
or wiring.
Failure to do so may cause an electric shock.
● Be sure to shut off all phases of the external power supply used by the system before cleaning or
retightening the terminal screw.
Failure to do so may result in a failure or malfunction of the module.
A loose screw may cause a drop of the module, short circuit or malfunction.
Overtightening may damage the screw, resulting in a drop of the module, short circuit or malfunction.
● Do not install the control or communication cable(s) together with the main circuit or power cables.
Keep a distance of 100mm or more between them.
Failure to do so may cause malfunctions due to noise.
● Always ground the FG terminal to the protective ground conductor.
Failure to do so may result in electric shock or malfunctions.
● Check the rated voltage and terminal layout and then wire the module correctly.
Connecting a power supply of a different voltage rating or incorrect wiring may cause a fire or failure.
● Completely connect each cable connector to each receptacle.
Failure to do so may cause malfunctions due to poor contact.
● Place the connection wires and cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in damage to the module and/
or cables or malfunctions due to poor cable connection.
● Do not install the control cable(s) together with the communication cable(s).
Doing so may cause malfunctions due to noise.
● Always use the data link terminal block for connection of a CC-Link dedicated cable to a master
module.
Care must be taken because, if the cable is incorrectly inserted into the general-purpose I/O terminal
block instead of the data link terminal block, the module will break down.
