Precautions for using the QJ51AW12AL
[Design Precautions]
[Design Precautions]
[Installation Precautions]
WARNING
●An AnyWireASLINK system has no control function for ensuring safety.
●When connecting a peripheral with the CPU module or connecting a personal computer with an
intelligent function module to modify data of a running programmable controller, configure an interlock
circuit in the program to ensure that the entire system will always operate safely.
For other forms of control (such as program modification or operating status change) of a running
programmable controller, read the relevant manuals carefully and ensure that the operation is safe
before proceeding.
Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure.
To prevent this, configure an interlock circuit in the program, and determine corrective actions to be
taken between the external device and CPU module in case of a communication failure.
●Do not write any data to the "system area" of the buffer memory in the intelligent function module.
Also, do not use any "use prohibited" signals as an output signal from the CPU module to the
intelligent function module. Doing so may cause malfunction of the programmable controller system.
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to
noise.
WARNING
●Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

[Installation Precautions]
[Wiring Precautions]
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the user's
manual for the CPU module used.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the
product.
●To mount the module, while pressing the module mounting lever located in the lower part of the
module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the
module until it snaps into place.
Incorrect interconnection may cause malfunction, failure, or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the module with
a screw.
●Tighten the screws within the specified torque range.
Undertightening can cause drop of the screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module.
Failure to do so may result in damage to the product.
●Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.
WARNING
●Shut off the external power supply (all phases) used in the system before installation and wiring.
Failure to do so may result in electric shock or damage to the product.

5
[Wiring Precautions]
CAUTION
●Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 ohms or less.
Failure to do so may result in electric shock or malfunction.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly.
Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or
failure.
●Tighten the terminal block screws within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or
malfunction.
●Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
●A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring.
Do not remove the film during wiring.
Remove it for heat dissipation before system operation.
●Do not apply the 24VDC power before wiring the entire AnyWireASLINK system. If the power is
applied before wiring, normal data transmission is not guaranteed.
●Connect a 24VDC external power supply to the device(s) in an AnyWireASLINK system.
●Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Failure to do so may result in malfunction due to noise.
●Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or
cables or malfunction due to poor contact.
●When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable connected to the terminal block, loosen the terminal screw.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.

[Startup and Maintenance Precautions]
[Startup and Maintenance Precautions]
[Disposal Precautions]
WARNING
●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal block screws.
Failure to do so may result in electric shock.
CAUTION
●Do not disassemble or modify the module.
Doing so may cause failure, malfunction, injury, or a fire.
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●Tighten the terminal block screws within the specified torque range.
Undertightening can cause drop of the component or wire, short circuit, or malfunction. Overtightening
can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
●After the first use of the product, do not mount/remove the module to/from the base unit, and the
terminal block to/from the module more than 50 times (IEC 61131-2 compliant) respectively.
Exceeding the limit of 50 times may cause malfunction.
●Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body.
Failure to do so may cause the module to fail or malfunction.
CAUTION
●When disposing of this product, treat it as industrial waste.

TERMS
Unless otherwise specified, this manual uses the following terms.
Term Description
Address A parameter assigned to a slave module to identify each node on the AnyWireASLINK network
Address writer A hand-held device to read/write parameters (including addresses) from/to a slave module
AnyWireASLINK
A system where sensors at the end of a control system are connected to a programmable controller in the most
suitable way.
With this system, a bridge module can detect sensor disconnection and a user can set the I/O operations of a slave
module on a bridge module without using I/O areas of the CPU module.
AnyWireASLINK bridge module A generic term for the NZ2AW1C2AL and NZ2AW1GFAL
AnyWireASLINK master module A generic term for the RJ51AW12AL, QJ51AW12AL, and LJ51AW12AL
ASLINKAMP A generic term for sensor amplifiers that have an AnyWireASLINK interface
ASLINKER A generic term for I/O devices that have an AnyWireASLINK interface
Buffer memory A memory in an intelligent function module, where data (such as setting values and monitoring values) exchanged
with a CPU module are stored
CPU module A generic term for the MELSEC-Q and -L series CPU modules
GX Developer
The product name of the software package for the MELSEC programmable controllers
GX Works2
Head module The abbreviation for the LJ72GF15-T2 CC-Link IE Field Network head module
ID
A parameter to identify whether the module is an input module or output module based on its address
Output slave module ID: Address
Input slave module/I/O combined slave module ID: Address + 200H
Intelligent function module A MELSEC-Q/L series module that has functions other than input and output, such as an A/D converter module and
D/A converter module
Master module A generic term for the QJ51AW12AL and LJ51AW12AL
MELSEC-L series The abbreviation for the Mitsubishi programmable controller MELSEC-L series
MELSEC-Q series The abbreviation for the Mitsubishi programmable controller MELSEC-Q series
Power cable (24V, 0V) A cable that connects a master module to a 24VDC external power supply
Programming tool A generic term for GX Works2 and GX Developer
Slave module A generic term for modules that communicate data with a master module
Terminating unit A waveform shaper
Transmission cable (DP, DN) A signal cable that connects a slave module to a master module
Transmission cycle time A data sampling interval
