Precautions for using the QJ51AW12AL

[Design 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.

[Design Precautions]

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.

1.1 AnyWireASLINK

The AnyWireASLINK is a high-speed and highly reliable system which releases the work site from complicated and

incorrect wiring.

In this network, sensors at the end of a control system are connected to a programmable controller in the optimum

form.

Furthermore, this network enables a mater module to detect sensor disconnection and enables a user to set the

operations of a slave module only using the areas, 32 points occupied, of a master module with the I/O assignment

setting.

The master module, a product of the joint development project with Anywire Corporation, allows the AnyWireASLINK

system to be constructed in a MELSEC-Q or MELSEC-L series programmable controller system.

1.2 Features

This section describes the features of the AnyWireASLINK.

(1) Flexible wiring

The AnyWireASLINK allows flexible connections if the overall cable distance of transmission cables (DP, DN) is

within 200m.

There is no restriction about, for example, the main line length, station-to-station distance, and number of

branches.

1

(2) Single-touch cable connection and disconnection

(3) Space saving

Moreover, because of a little restrictions about cables, cables used for other networks can be used for the

AnyWireASLINK without modification, resulting in reduced wiring man-hours and cable cost.

*1 Before using, check the performance specifications. ( Page 26, Section 3.2.1)

Using a dedicated connector enables cables to be connected and disconnected with a single operation and

eases slave module addition and replacement.

*1 For wiring with the dedicated connectors, contact Anywire Corporation.

The system needs much less space because of a wide selection of small-type slave modules (manufactured by

Anywire Corporation).

(2) Effects of the double check system

(a) Input

Unless the same data is received twice successively on the master module side, the input area data is not

updated.

A minimum of one-transmission cycle time and a maximum of two-transmission cycle time are required as the

data response time.

Therefore, when an input signal is shorter than two-transmission cycle time, the input data may not be captured

depending on the timing.

To ensure the response, provide an input signal that is longer than two-transmission cycle time.

(b) Output

As the double check is performed on the slave module side, the time required is the same as that for input,

namely a minimum of one-transmission cycle time and a maximum of two-transmission cycle time.

To tighten the terminal block, a flathead screwdriver having a tipped size of 0.4  2.5mm is required.

Before removing the transmission cable terminal block, check that the terminal block mounting screws on both

ends are completely loosened (removed from the socket).

Pulling the terminal block with excessive force while the terminal block mounting screws on both ends are still

tightened may damage the devices.

Before connecting the terminal block, check that there are no short-circuits due to the disconnected or frayed
wires and tighten the terminal block mounting screws at both ends securely. (Tightening torque: 0.2 to 0.3Nm)

(3) Cable processing

Bare cables can be connected to the transmission cable terminal block; however, for safety reasons, it is

6.2.1 Wiring precautions

The following shows the wiring precautions in the AnyWireASLINK system.

• In the AnyWireASLINK system, signals and power are supplied to a slave module with two types of

transmission cables; DP and DN. Therefore, using a stranded wire of 1.25 or larger for the main line is

recommended.

• Wires such as general-purpose wires, cabtyre cables, and flat cables can be used.

• Do not run multiple transmission cables (DP, DN) using a multicore cable. Running multiple transmission

cables (DP, DN) together may cause noise, resulting in a malfunction.

CHAPTER 6 INSTALLATION AND WIRING

DP
DN
DP
DN

• The voltage should not fall below the lower limit of the allowable voltage range due to the voltage drop

caused by the cable. If the voltage falls below the lower limit, malfunctions may occur.

• Do not connect soldered cables directly to the terminals. Doing so may loosen the screws, resulting in a poor

contact.

• Use a crimping tool to connect a cable to a bar solderless terminal.

• Before inserting a bar solderless terminal, check the shapes of the wire insertion opening and bar solderless

terminal. Then, insert the terminal in the correct orientation. Inserting a bar solderless terminal wider than the
wire insertion opening may damage the terminal block. ( Page 44, Section 6.2 (3))

● A slave module address is not deleted even when the power supply of a programmable controller or a 24VDC external
power supply is turned off. The address is retained until a new address is set when a system is configured.

● For the address setting, ensure that the address occupied by the slave module does not exceed the number of
transmission points set in the master module. For the operation mode setting of the master module, refer to Page 54,
Section 7.1.2.

● In the slave module, a value between 0 and 254 can be written. (This is not an ID value.) Note that 255 cannot be set.
Doing so may cause a No ID setting error.

CHAPTER 7 VARIOUS SETTINGS

7.3 Automatic Address Detection Function

Automatic address detection is a function to store the IDs (addresses) of the connected slave modules in the EEPROM

of the master module.

The parameters of the connected devices are automatically updated after storage in EEPROM of the master module

followed by detection of IDs (addresses) not set and the same IDs (addresses).

The ID (address) information stored in the EEPROM is held even when the power is turned off. However, information

about unset IDs and the same IDs and the parameter information of each slave module are not held.

Whenever starting the system or changing the system configuration, set the correct addresses to all the slave modules

and perform the automatic address detection.

7.3.1 Performing the automatic address detection

To perform the automatic address detection, use the SET switch or Automatic address detection command (Yn1).

(1) Using the SET switch

1. Check that all of the slave modules are operating normally.

2. Keep pressing the SET switch on the master module until the SET LED (green) turns on.

(At this time, Automatic address detection flag (X(n+1)4) turns on.)

3. When the SET LED flashes for a while and turns off, the ID (address) has been stored.

4. When Automatic address detection flag (X(n+1)4) turns off, automatic address detection is

completed.

(2) Using Automatic address detection command (Yn1)

1. Check that all of the slave modules are operating normally.

2. Turn on and off Automatic address detection command (Yn1). ( Page 33, Section 3.4)

(At this time, Automatic address detection flag (X(n+1)4) turns on.)

3. When the SET LED flashes for a while and turns off, the ID (address) has been stored.

4. When Automatic address detection flag (X(n+1)4) turns off, automatic address detection is

completed.

0064H Master module hardware error

0065H Master module hardware error

0067H Master module hardware error

00C8H Transmission cable voltage drop error

00C9H DP/DN short error

(b) Perform the automatic address detection in the following cases.

• When starting the system operation (when all of the slave modules are connected and operating normally.)

• When adding a slave module after starting the system operation

• When removing a slave module after starting the system operation

• When changing the address of a slave module after starting the system operation

(c) After performing the automatic address detection, check that there is no

inconsistency between the actual system configuration and the IDs registered in the

master module, referring to the value stored in Number of the IDs of the connected

modules (Un\G9216) and values stored in Connected module ID information storage

areas (Un\G9217 to Un\G9344).

(d) Use an address writer to set the ID (address) in a slave module that has the same ID

as other slave modules or where an ID is not set. Then execute automatic address

detection again.

(e) Do not perform the automatic address detection in any of the following cases. If

executed, the automatic address detection is not processed.

• When Parameter access completion flag (X(n+1)1) is off

• When Automatic address detection flag (X(n+1)4) is on

Remark

8.6 Same ID Used Detection Function

This function allows the master module to check whether the same ID is used for all the slave modules with the

addresses that have been automatically detected.

● IDs are detected with automatic address detection. If the CPU module is reset or the system is powered off after ID
duplication detection, the ID duplication status cannot be checked until the automatic address detection is performed
again.

● Only a single ID is stored in Number of the alarm IDs (Un\G9984) and Alarm ID information storage area (Un\G9985 to
Un\G10112) when the same ID is the cause. For example, when multiple modules have ID 10, "1" is stored in Number of
the alarm IDs (Un\G9984) and "10" is stored in Alarm ID information storage area (Un\G9985 to Un\G10112).

(1) Same ID used status

When the AnyWireASLINK system is in the following status, the same ID is used for multiple modules.

Even in the same ID used status, the AnyWireASLINK bit transmission is not stopped.

• Slave module alarm signal (X(n+1)0) turns on.

• Same ID used error (error code: 0190

duplicated ID is stored in Latest error ID storage area (Un\G10257).

• An error (error code: 0190H) is displayed in the detailed information section on the system monitor window of

GX Works2.

• The relevant ID is stored in Alarm ID information storage area (Un\G9985 to Un\G10112).

Then set a unique ID (address) in all the slave modules. ( Page 55, Section 7.2)

Error status is cleared by executing automatic address detection in the master module after setting the IDs
(addresses) in the slave modules. ( Page 57, Section 7.3)

While an ID (address) is used for multiple slave modules, executing either of the following can eliminate the same ID used
error. However, the address is still used for the multiple slave modules.

• Powering off and on the AnyWireASLINK system

• Turning on and off Error flag clear command (Yn0)

● ID unset detection is performed with automatic address detection. If the CPU module is reset or the system is powered off
after the ID unset detection, the ID unset status cannot be checked until automatic address detection is performed again.

● Only a single ID is stored in Number of the alarm IDs (Un\G9984) and Alarm ID information storage area (Un\G9985 to
Un\G10112) when no ID setting is the cause. For example, when multiple modules have ID 255, "1" is stored in Number
of the alarm IDs (Un\G9984) and "255" is stored in Alarm ID information storage area (Un\G9985 to Un\G10112).

(1) ID unset status

When the AnyWireASLINK system is in the following status, a module with no ID setting has been detected.

Even in the no ID number setting status, the AnyWireASLINK bit transmission is not stopped.

• Slave module alarm signal (X(n+1)0) turns on.

• No ID setting error (error code: 0191

IDs are stored in Latest error ID storage area (Un\G10257).

• An error (error code: 0191H) is displayed in the detailed information section on the system monitor window of

(2) How to recover from the ID unset status

Check Number of the alarm IDs (Un\G9984) and Alarm ID information storage area (Un\G9985 to Un\G10112).
Then set addresses to slave modules. ( Page 55, Section 7.2)

Check that "255" is not set as the address of the slave module.

The IDs of the slave module is stored in the master module and the error status is cleared by performing the
automatic address detection in the master module after setting the IDs (addresses) in the slave modules. (

Page 57, Section 7.3)

While the ID (address) of a slave module is not set, executing either of the following can eliminate the no ID setting error.
However the address of the slave module is still not set.

completed, Parameter access completion flag (X(n+1)1) automatically turns on.

3. Turn on Parameter batch read command for the slave module (Y(n+1)1) to check that the settings

have been saved in the slave module.

● During the parameter access, parameter batch read, and parameter batch write, Parameter access completion flag
(X(n+1)1) is off. When Parameter access completion flag (X(n+1)1) is off, the parameter access, parameter batch read,
and parameter batch write cannot be executed.

● Upon parameter batch read or parameter batch write, the values stored in Parameter access setting (Un\G10320) and
Parameter access target module ID specification (Un\G10321) are ignored.

● The buffer memory address start number of the parameter storage location of each ID is stored in the following area. The
48 words from the buffer memory address start number is the parameter information of each ID.

• The buffer memory addresses of the parameter storage locations of output slave modules are Un\G10496 to
Un\G10751.

• The buffer memory addresses of the parameter storage locations of input slave modules or I/O combined slave
modules are Un\G11008 to Un\G11263.

Parameters cannot be set in the following cases.

• Upon an error in the AnyWireASLINK system (Example: Short-circuit, 24VDC external power supply

voltage drop)

• Within approximately five seconds after the AnyWireASLINK system is powered on or the system is reset

• When the automatic address detection is in progress (While Automatic address detection flag (X(n+1)4) is

on)

• When parameter access is in progress (While Parameter access request command for the slave module

(Y(n+1)0), Parameter batch read command for the slave module (Y(n+1)1), or Parameter batch write

command for the slave module (Y(n+1)2) is on)

• When any of the following errors has occurred

0065H Master module hardware error

0067H Master module hardware error

00C8H Transmission cable voltage drop error

00C9H DP/DN short error

CHAPTER 8 FUNCTIONS

(b) Parameter reading and writing

• If parameters are not read after being written, the contents of the parameters do not match between the

master module and slave module. Make sure to read parameters after writing them.

• When parameter reading or writing is in progress, Parameter access completion flag (X(n+1)1) turns off.

Refer to the section describing the parameter access timing, and adjust the access timing. ( Page 72,

Section 8.8 (6))

• When parameter reading or writing is in progress, do not execute re-access to the parameters and

automatic address detection. Doing so can cause a malfunction of the module.

(c) Parameter access, parameter batch read, and parameter batch write

• These operations cannot be performed to a slave module whose ID has not been registered in the master

module.

• Clear a no ID setting error or a same ID used error of the slave module. Then perform the operations.

(d) Others

• The parameter batch read is executed at the same time as when the automatic address detection is

executed.

• Note that the master module may communicate with a slave module and output parameters even if no

parameters are set.

A malfunction has been detected in the slave module hardware.

Perform either of the following operations:

• Reset the CPU module, or power off and on the system.

• Power off and on the slave module.

Check that there is no influence from noise.

The master module accessed the parameter of the ID where the

automatic address detection has not been performed. Check

Number of the alarm IDs (Un\G9984) and Alarm ID information

storage area (Un\G9985 to Un\G10112), find out the error ID, and

perform the following:

• Check that the slave module ID for parameter access in the actual

system matches that of the program. Especially note that the input

slave module ID is the input slave module address + 200

the I/O combined slave module ID is the I/O combined slave

module address + 200

.

• When creating a new system, adding or removing a slave module,

or changing the address of the slave module, perform the

automatic address detection. After performing the automatic

address detection, check that the number of slave modules and

the address are consistent with those of the actual system.

The slave module has detected a signal of writing a parameter that

cannot be set to the slave module itself.

Check Number of the alarm IDs (Un\G9984) and Alarm ID

information storage area (Un\G9985 to Un\G10112) to find out the

error ID. Then check that the slave module parameter setting value is

within the allowable setting range.

The slave module has notified of error status. Check the target

module's status details and solve the problem.

The same ID (address) has been set to some of the connected slave

modules.

Check Number of the alarm IDs (Un\G9984) and Alarm ID

information storage area (Un\G9985 to Un\G10112) to find out the

error ID. Check the ID (address) of the slave module, and then set a

unique number.

There is a slave module with no address setting. Perform the

following:

• Set the address of the slave module.

• Set the address of the slave module to a value other than 255.

Data backed up in the SD memory card of the CPU module has been

damaged. Check that there is no influence from noise, and perform

the following:

• Reset the CPU module or power off and on the system, and then

set the CPU module to the RUN state again.

• Use normal backup data, and restore the data.

• Disable the write protect switch of the SD memory card (write

enabled).

If the error occurs again, the SD memory card may be in failure.

Please consult your local Mitsubishi representative.

10.6 Troubleshooting of the Master Module

This section describes the troubleshooting of the master module.

(1) When the RUN LED does not turn on even when the power supply is turned on.

Check item Action

Check the installation or connection of the master module. Remove the master module. Then mount or connect it again.

Examine the system configuration so that the internal current

consumption does not exceed the rated output current of the

power supply module.

For how to calculate the current consumption of the system,

Check the internal current consumption of the entire system.

Check for a programmable controller error using the

programming tool.

(2) When the LINK LED on the master module does not flash

(3) When the ALM LED on the master module is flashing at 0.2 second intervals

Check item Action

Check the power supply voltage of the 24VDC external

power supply.

Check that the power cables (24V, 0V) are not short-

circuited.

Check the wiring of the terminal blocks.

Adjust the power supply voltage of the 24VDC external

power supply within the rated value (21.6VDC to 27.6VDC).

(The recommended voltage is 26.4VDC.)

• Check that the power cables (24V, 0V) are not

disconnected or short-circuited.

• When crimping the link connector, check that the pin layout

is correct.

• Check that the 24VDC external power supply is properly

connected to the terminal blocks of the master module and

the slave module.

• Check that there is no short circuit or incorrect wiring and

screws are tightened sufficiently.
