[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) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.

(2) When the programmable controller detects an abnormal condition, it stops the operation and all

outputs are:

• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.

• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.

(3) All outputs may be turned on if an error occurs in a part, such as an 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 "General Safety Requirements" in the MELSEC iQ-R Module Configuration
Manual.

(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in 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 circuit, such as a fuse.

● For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.

● When connecting an external device with a CPU module or 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,
parameter change, forced output, or operating status change) of a running programmable controller,
read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper
operation may damage machines or cause accidents.

[Design Precautions]

WARNING

● 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" and "write-protect area" of the buffer memory in the
module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to
each module. Doing so may cause malfunction of the programmable controller system. For the
"system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the
module used.

● If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire
system will always operate safely even if communications fail. Failure to do so may result in an
accident due to an incorrect output or malfunction.

● To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.

● An AnyWireASLINK system has no control function for ensuring safety.

[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.

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.

● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design circuits so
that the entire system will always operate safely, regardless of the time.

● Do not power off the programmable controller or reset the CPU module while the settings are being
written.
Doing so will make the data in the flash ROM and SD memory card undefined. The values need to be
set in the buffer memory and written to the flash ROM and SD memory card again. Doing so also may
cause malfunction or failure of the module.

● When changing the operating status of the CPU module from external devices (such as the remote
RUN/STOP functions), select "Do Not OPEN in Program" for "Open Method Setting" of "Module
Parameter". If "OPEN in Program" is selected, an execution of the remote STOP function causes the
communication line to close. Consequently, the CPU module cannot reopen the line, and external
devices cannot execute the remote RUN function.

A double verification is an error control system. In this system, cycle data in AnyWireASLINK transmission is recognized as

valid data if the data matches with the data of the last transmission or is ignored as invalid data if the data does not match with

the last data. The double verification ensures reliability of communication.

There are two types of double verification: double verification in 1-bit unit and double verification in 16-bit unit.

Overview

■Double verification in 1-bit unit

If one bit of data is the same between two successive transmission cycles, the data is valid and I/O data is communicated.

(1) Transmission cycle (last)
(2) Transmission cycle (current)
(3) I/O data
(4) This data is compared with the verification data (one bit) of the last transmission cycle.

■Double verification in 16-bit unit

If one word (16 bits) of data is the same between two successive transmission cycles, the data is valid and I/O data is

communicated.

1

(1) Transmission cycle (last)
(2) Transmission cycle (current)
(3) I/O data
(4) The data is compared with the verification data (one word) of the last transmission cycle.

The double verification in 1-bit unit is suitable for slave modules that handle information in units of bits such as

ASLINKER.

The double verification in 16-bit unit is suitable for slave modules that handle information in units of 16 bits

such as ASLINKAMP (analog input module).

Setting method

Set the double verification of bit data in "Double verification" of "Basic setting". ( Page 50 Bit data double verification

1.3 Remote Address Change Function

ID

0200H 0210H

With this function, an ID (address) of a slave module can be changed using the buffer memory area without an address writer.

Applicable slave module

For the slave modules that support the remote address change function, consult Anywire Corporation.

Operating procedure

1. Execute automatic address detection to check that no error has occurred in the AnyWireASLINK system. ( Page 58

Automatic Address Detection Function)

2. Specify an access method to a slave module.

Store 0002H (remote address change) in 'Parameter access setting' (Un\G10320).

3. Specify an ID of the slave module to be accessed.

Store the ID to be changed (old ID) in 'Parameter access target module ID specification' (Un\G10321).

ID Description

0000H to 00FEH ID of a bit output slave module

0200H to 02FEH ID of a bit input slave module or bit I/O combined slave module

0400H to 05FEH ID of a word output slave module

0600H to 07FEH ID of a word input slave module or word I/O combined slave module

4. Specify a new ID of the slave module.

Store the new ID in 'Change ID specification' (Un\G10323).

ID Description

0000H to 00FEH ID of a bit output slave module

0200H to 02FEH ID of a bit input slave module or bit I/O combined slave module

0400H to 05FEH ID of a word output slave module

0600H to 07FEH ID of a word input slave module or word I/O combined slave module

If the specified ID has already been registered or is out of the allowable specification range, an error occurs.

5. Turn on and off 'Parameter access request command for the slave module' (Y10).

At this time, 'Parameter access completion flag' (X11) turns off, and 'Parameter accessing flag (with handshake)' (XB) turns

on. When the parameter access is completed, 'Parameter access completion flag' (X11) automatically turns on.

6. After changing the IDs of all the target slave modules, execute automatic address detection. ( Page 58 Automatic

Address Detection Function)

Precautions

• Before executing this function, make sure to execute automatic address detection to check that no error has occurred in the

AnyWireASLINK system. ( Page 58 Automatic Address Detection Function)

• This function cannot be executed for slave modules separated from the RJ51AW12AL because of disconnection or slave

modules having the same ID. Use an address writer to change the IDs of such slave modules.

• This function can be executed if only one slave module having no ID exists within one AnyWireASLINK line. If IDs of

multiple slave modules are not set, it is recognized as an ID duplication. Thus, the IDs cannot be changed.

1 FUNCTIONS

1.3 Remote Address Change Function

1.4 Same ID Used Detection Function

This function checks whether the same ID is used for multiple slave modules through automatic address detection or same

address used check. The LEDs of the relevant slave modules are forcibly turned on.

• ID duplications are detected through automatic address detection or same address used check. If the CPU

module is reset or the power is turned off after ID duplication detection, the same ID used status cannot be

checked until automatic address detection or same address used check is executed again.

• Even if an ID is assigned to multiple modules, a single ID is stored in 'Number of the alarm IDs' (Un\G9984)

and 'Alarm ID information storage area' (Un\G9985 to Un\G10112). For example, even when multiple

modules have an ID 000AH, "1" is stored in 'Number of the alarm IDs' (Un\G9984) and "000AH" is stored in

'Alarm ID information storage area' (Un\G9985 to Un\G10112).

How to execute automatic address detection

For details on automatic address detection, refer to the following.
Page 58 Automatic Address Detection Function

How to execute same address used check

Turn off and on 'Overlap address inspection command' (Y2). If 'Overlap address inspection flag' (X15) turns on and off, it

indicates that the same address used check is completed.

The same address used check cannot be executed under any of the following conditions.

• When an error occurs 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 system is reset

• While 'Adjustment mode executing flag' (XF) is on

• While 'Parameter access completion flag' (X11) is off

• When the automatic address detection is in progress (While 'Automatic address detection flag' (X14) is on)

• When the same address used check is in progress (While 'Overlap address inspection flag' (X15) is on)

• When the parameter access is in progress (While 'Parameter access request command for the slave module' (Y10),

'Parameter batch read command for the slave module' (Y11), or 'Parameter batch write command for the slave module'

(Y12) is on)

• When any of the following errors has occurred

1.4 Same ID Used Detection Function

21

How to check the 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 transmission does not stop.

• 'Slave module alarm signal' (X10) turns on.

• Same ID used error (error code: 0D90H) is stored in 'Latest error code storage area' (Un\G10256) and the same ID is

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

• An error (error code: 0D90H) is displayed on an engineering tool. ( Page 75 Checking with the "Module Diagnostics"

window)

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

*1 If multiple errors occur simultaneously, the latest error is displayed.

*1

*1

How to recover from same ID used status

Check 'Number of the alarm IDs' (Un\G9984) and 'Alarm ID information storage area' (Un\G9985 to Un\G10112). Then set a
unique ID (address) in all the slave modules. ( Page 102 Number of the alarm IDs, Page 103 Alarm ID information

storage area)

Set IDs (addresses) of slave modules and execute automatic address detection of the RJ51AW12AL. Then, the IDs of the
slave modules are stored in the RJ51AW12AL and the error is cleared. ( Page 58 Automatic Address Detection Function)

Precautions

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 off and on 'Error flag clear command' (Y0)

1.5 Module with No ID Setting Detection Function

This function detects slave modules with no ID assigned (default ID) through automatic address detection or same address

used check.

*1*2

Input slave module, I/O combined slave module 02FFH

Output slave module 00FFH

*1 Bit slave modules and word slave modules have the same default ID.
*2 The default address of bit slave modules is 255 or 511.

The default address of word slave modules is 511.

• Modules with no ID set are detected through automatic address detection or same address used check. If

the CPU module is reset or the power is turned off after a module with no ID set is detected, the no ID

number setting status cannot be checked until automatic address detection or same address used check is

executed again.

• Even if no ID is assigned to modules, a single ID is stored in 'Number of the alarm IDs' (Un\G9984) and

'Alarm ID information storage area' (Un\G9985 to Un\G10112). For example, even when multiple modules

have an ID 00FFH, "1" is stored in 'Number of the alarm IDs' (Un\G9984) and "00FFH" is stored in 'Alarm ID

information storage area' (Un\G9985 to Un\G10112).

Precautions

■Parameter setting

Parameters cannot be set in the following cases.

• When an error occurs 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 system is reset

• While 'AnyWireASLINK version compatibility inspection executing flag' (XD) is on

• While 'Adjustment mode executing flag' (XF) is on

• When the automatic address detection is in progress (While 'Automatic address detection flag' (X14) is on)

• When the same address used check is in progress (While 'Overlap address inspection flag' (X15) is on)

• When the parameter access is in progress (While 'Parameter access request command for the slave module' (Y10),

'Parameter batch read command for the slave module' (Y11), or 'Parameter batch write command for the slave module'

(Y12) is on)

• When any of the following errors has occurred

Error code Error description

0CC8H Transmission cable voltage drop error

0CC9H DP/DN short error

0CCBH 24V/DP short error

1867H EEPROM access error

3064H RJ51AW12AL hardware failure

3065H

3066H

3068H CPU module stop error (IORSTL signal detection)

3069H System error (NMI signal detection)

306BH CPU module error (ITERR signal detection)

306CH ASIC access error (library I/F function access error)

■Parameter reading and writing

• When parameter read or write is in progress, 'Parameter access completion flag' (X11) turns off. Refer to the section

describing the parameter access timing, and adjust the access timing. ( Page 38 Check of the parameter access

completion)

• While the parameters are being read or written, do not execute re-access to the parameters, automatic address detection,

same address used check, or AnyWireASLINK version compatibility inspection.

■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 RJ51AW12AL.

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

• Because parameter batch write updates all parameters of target slave modules, all parameters to which no changes are

made need to be set correctly. Be sure to execute parameter batch read right before executing parameter batch write.

Then, import the latest parameters and execute parameter batch write. Executing parameter batch write without executing

parameter batch read will result in a malfunction.

■Others

• When the automatic address detection is executed, the parameter batch read is executed simultaneously.

• Note that the RJ51AW12AL may communicate with a slave module and output parameters even if no parameters are set.

• When Y10, Y11, and Y12 are turned on at the same time, the order of priority will be Y10 > Y11 > Y12.

1.12 Slave Module Parameter Read/Write

1.13 Easy Replacement function for One Slave Module

When the slave module is replaced with the one of the same type, this function automatically sets the address and the device

parameter with no need of using an address writer.

When using this function, check the production information of the RJ51AW12AL. ( Page 133 Added or

Changed Functions)

After the slave module replacement, the RJ51AW12AL checks that the new slave module has the same type as the old one.

When the types of the old and new slave modules match, the following backup data is restored to the new slave module so

that the new slave module can be used.

• Module ID

• Device parameters 1 to 19 (parameter value detected by the automatic address detection)

*1 Parameter information acquired through parameter access cannot be restored.

*1

Applicable slave module

For slave modules that support this function, consult Anywire Corporation.

Replace the slave module with the one that meets the following conditions.

• Unused slave module of which address and device parameter are not changed

• Slave module to which the teaching is not executed

1.13 Easy Replacement function for One Slave Module

41

Use conditions

The following conditions must be met to use this function.

• The RJ51AW12AL supports this function. ( Page 133 Added or Changed Functions)

• The new slave module supports this function.

• The automatic address detection is performed correctly while "Easy replacement enable/disable setting for one slave

module" is set to "0: Enable" in the module parameter of the RJ51AW12AL. (Parameter information of the slave module is

stored in the RJ51AW12AL.)

• Other slave modules than the one to be replaced have no errors.

• Slave modules with no IDs assigned are not registered.

• 'Adjustment mode executing flag' (XF) turns off.

Operating procedure

1. Turn off the 24VDC external power supply connected to the RJ51AW12AL.

Voltage of the transmission cable drops, and 'Transmission cable voltage drop error' (X3) turns off and on.

2. Disconnect the slave module to be replaced. (Two or more slave modules cannot be replaced at the same time.)

3. Connect an unused slave module of the same type. ( Page 41 Applicable slave module)

4. Turn on the 24VDC external power supply connected to the RJ51AW12AL.

A DP/DN disconnection error occurs, and 'DP/DN disconnection error' (X4) turns off and on.

5. 'One slave module changing flag' (X16) turns off and on, and the backup data is restored from the RJ51AW12AL.

6. After the backup data is restored, 'One slave module changing flag' (X16) turns on and off, and 'Slave module

replacement completion flag' (X17) turns off and on.

Simultaneously, the error status of the RJ51AW12AL is cleared. (As with turning off and on 'Error flag clear command' (Y0)
(Page 93 Error flag clear command: Y0))

7. Approximately five seconds later, 'Slave module replacement completion flag' (X17) turns on and off, and the

replacement of the slave module is completed.

• Every time "Easy replacement enable/disable setting for one slave module" is changed from "1: Disable" to

"0: Enable", execute the automatic address detection. Executing the automatic address detection with the

easy one-device replacement enabled stores the device parameters of the slave module to the

RJ51AW12AL.

• Unless the automatic address detection is executed, the replacement of the slave module will not be

completed successfully, and a malfunction may be caused.

• The easy replacement function for one slave module stops if an error occurs in midstream. Eliminate the

error cause, and follow the procedures from step 1 again.

Address

This function sets the start address of the word data transmission. Setting the start address shortens the word transmission

cycle time.

Unregistered addresses between address 0 and the registered address are accessed during word transmission. Although this

access takes extra time for word transmission cycle, setting the number of word data points and transmission start address

enhances the efficiency of transmission.

(1) Registered address (word slave module)
(2) Access to unregistered addresses existing before the registered address causes extra time for word transmission cycle. (Number of word data points setting:

512 words (256 input words/256 output words))
(3) When the word data points setting is 2 words (1 input word/1 output word) and the word data transmission start address is set to 250, the address targeted

for access will be 250 only.

When using this function, check the production information of the RJ51AW12AL. ( Page 133 Added or

Precautions

Ex.

• 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.

• In the address setting, ensure that the address occupied by the slave module does not exceed the number of transmission

points set in the RJ51AW12AL. For the operation mode setting of the RJ51AW12AL, refer to the following.

Page 49 Bit data setting

When "Transmission points setting" is set to "0: 64 points (32 input points/32 output points)", the effective address range is

between 0 and 31.

If the address is set to 32 or larger, the slave module does not communicate I/O data.

When "Word data points setting" is set to "4: 8 words (input 4 words, output 4 words)", the effective address range is between

0 and 3.

If the address is set to 4 or larger, the slave module does not communicate I/O data.

• Do not use the following values when writing the address of the slave module. Doing so will cause a No ID setting error.

2.6 Automatic Address Detection Function

Automatic address detection refers to a function that stores the IDs (addresses) of the connected slave modules in the

EEPROM of the RJ51AW12AL.

Pressing the SET switch on the RJ51AW12AL enables this function and enables the RJ51AW12AL to detect and store IDs

(addresses) of connected slave modules.

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

unset IDs, 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

execute the automatic address detection.

Executing the automatic address detection

To execute the automatic address detection, use the SET switch or 'Automatic address detection command' (Y1).

Using the SET switch

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

2. Keep pressing the SET switch on the RJ51AW12AL until the SET LED turns on.

At this time, 'Automatic address detection flag' (X14) 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' (X14) turns off, the automatic address detection is completed.

Using 'Automatic address detection command' (Y1)

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

2. Turn on and off 'Automatic address detection command' (Y1).

At this time, 'Automatic address detection flag' (X14) 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' (X14) turns off, the automatic address detection is completed.

Precautions

■Situations in which automatic address detection cannot be executed

Automatic address detection cannot be executed in the following cases.

• When an error occurs 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 system reset recovery

• While 'Adjustment mode executing flag' (XF) is on

• While 'Parameter access completion flag' (X11) is off

• When automatic address detection is in progress (While 'Automatic address detection flag' (X14) is on)

• When the same address used check is in progress (While 'Overlap address inspection flag' (X15) is on)

• When the easy replacement setting for one slave module is in progress (While One slave module changing flag' (X16) is

off)

• When the parameter access is in progress (While 'Parameter access request command for the slave module' (Y10),

'Parameter batch read command for the slave module' (Y11), or 'Parameter batch write command for the slave module'

(Y12) is on)

• When any of the following errors has occurred

3069H System error (NMI signal detection)

306BH CPU module error (ITERR signal detection)

306CH ASIC access error (library I/F function access error)

2

■Situations in which automatic address detection is required

Execute 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

• When enabling easy replacement setting for one slave module

• When changing device parameters of a slave module or restoring data with the data backup/restoration after enabling easy

replacement setting for one slave module

■Check after execution of automatic address detection

After executing automatic address detection, check that there is no inconsistency between the actual system configuration

and the IDs registered in the RJ51AW12AL, 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 area' (Un\G9217 to Un\G9344).

■Executing automatic address detection again

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.

■Word slave modules

When the automatic address detection function is executed with a word slave module connected, set the number of word data
points in the parameter setting to 2 words (1 input word/1 output word) or larger. (Page 51 Word data point setting)

If the number of word data points is not set, the address is not stored in the EEPROM of the RJ51AW12AL even when the

automatic address detection function is executed.

3.2 Communication Example When the Slave Module

(1) (2) (3) (4) (5) (6)

is Added or Deleted

The parameter of the slave module is moved over in order of ID and stored in 'Parameter storage area' (Un\G12288 to

Un\G18431) after the automatic address detection function is executed.

Because of this, the address of the parameter storage area for the slave module later than the ID where the slave module is

added or deleted in the AnyWireASLINK system is changed. (The parameter of a non-existing ID is deleted and displayed.)

Therefore, the address of the slave module later than the ID where the slave module is added or deleted must be changed

when a program is created with buffer memory addresses directly specified. (This also applies if the ID is changed and sorting

order is switched.)

To create a program that reads/writes the parameter without considering the addition or deletion of slave modules, use the

following buffer memory areas.

Address Name

Un\G10496 to Un\G10751 Parameter storage location memory number (bit output)

Un\G11008 to Un\G11263 Parameter storage location memory number (bit input)

Un\G19456 to Un\G19967 Parameter storage location memory number (word output)

Un\G19968 to Un\G20479 Parameter storage location memory number (word input)

After automatic address detection, the start address of the buffer memory that stores the parameter of the ID is stored in these
areas. ( Page 105 Parameter storage location memory number)

3.2 Communication Example When the Slave Module is Added or Deleted

Reading the sensing level information

The sensing level is a device parameter for the ASLINKAMP or ASLINKSENSOR only.

This example uses a system configuration in which an ASLINKAMP or ASLINKSENSOR is used as a slave module with

address 20 instead of the ASLINKER M12 connector type (mixed type) in the system configuration above.

This section describes an example of a program in which the photoelectric transmission type ASLINKSENSOR is used.

The photoelectric transmission type operates based on the combination of the two types: "Transmission floodlight type" and

"Transmission light receiving type".

If the slave module with address 20 is replaced with the ASLINKSENSOR, two slave modules, "Transmission floodlight type"

and "Transmission light receiving type" (both have address 20.), will be added. Thus, the system is configured with seven

slave modules.

The following shows a program example that reads the sensing level of the slave module (address: 20) when the start I/O

number of the RJ51AW12AL is assigned to X/Y00 to X/Y1F.

Number of the error IDs

■Number of the error IDs (Un\G8192)

This buffer memory area stores the number of error IDs that send no response due to disconnection of the transmission cable

(DP, DN) or a failure in the slave module alone among the IDs of the connected modules. (Up to 128 IDs)

The stored values are retained until the power is turned off and on or 'Error flag clear command' (Y0) is turned off and on after

the error is cleared.

However, if the error status automatic recovery function is enabled, the number of slave modules (number of error IDs) from

which errors are cleared automatically decreases.

Data update timing

After automatic address detection, the data are updated as soon as a response error is detected.

Error ID information storage area

■Error ID information storage area (Un\G8193 to Un\G8320)

When the transmission cables (DP, DN) are disconnected or an error in a slave module or an error (error code: 0CCAH,

0D30H) occurs, this buffer memory area stores all the error IDs in the ascending order. (Up to 128 IDs)

The IDs to be stored are as follows.

• 0000H to 00FEH: ID of a bit output slave module

• 0200H to 02FEH: ID of a bit input slave module or bit I/O combined slave module

• 0400H to 05FEH: ID of a word output slave module

• 0600H to 07FEH: ID of a word input slave module or word I/O combined slave module

• 00FFH: Unset IDs of bit output slave modules and word output slave modules

• 02FFH: Unset IDs of bit input slave modules and word input slave modules

The stored values are retained until the power is turned off and on or 'Error flag clear command' (Y0) is turned off and on after

the error is cleared.

However, if the error status automatic recovery function is enabled, the ID of a slave module from which an error is cleared

turns off automatically.

Data update timing

After automatic address detection, the data are updated as soon as a response error is detected.
