[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.
● 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 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.
● 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.

[Design Precautions]
WARNING
● 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.
● Analog outputs may remain on due to a failure of the module. Configure an external interlock circuit
for output signals that could cause a serious accident.
[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 undefined. The values need to be set in the
buffer memory and written to the flash ROM 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" in the module
parameters. 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.
● Power on or off the external power supply while the programmable controller is on. Failure to do so
may result in incorrect output or malfunction.
● At on/off of the power or external power supply, or at the output range switching, a voltage may occur
or a current may flow between output terminals for a moment. In this case, start the control after
analog outputs become stable.

[Installation Precautions]
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]
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines included with the base unit. Failure to do so may result in electric shock, fire, malfunction,
or damage to or deterioration of the product.
● To mount a module, place the concave part(s) located at the bottom onto the guide(s) of the base unit,
and push in the module until the hook(s) located at the top 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.
● When using an extension cable, connect it to the extension cable connector of the base unit securely.
Check the connection for looseness. Poor contact may cause malfunction.

[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.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in
failure.
● Check the rated voltage and signal 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 fire
or failure.
● Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or
malfunction.
● Securely connect the connector to the module. Poor contact may cause malfunction.
● 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.
● 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. Do not clamp the
extension cables with the jacket stripped.
● Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
● Tighten the terminal screws or connector screws within the specified torque range. Undertightening
can cause drop of the screw, short circuit, fire, or malfunction. Overtightening can damage the screw
and/or module, resulting in drop, short circuit, fire, or malfunction.
● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. 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.
● 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.
● Programmable controllers must be installed in control panels. Connect the main power supply to the
power supply module in the control panel through a relay terminal block. Wiring and replacement of a
power supply module must be performed by qualified maintenance personnel with knowledge of
protection against electric shock.
For wiring, refer to the MELSEC iQ-R Module Configuration Manual.
● For Ethernet cables to be used in the system, select the ones that meet the specifications in the user's
manual for the module used. If not, normal data transmission is not guaranteed.

[Startup and Maintenance Precautions]
CAUTION
● 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.
● 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 disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may cause the module to fail or malfunction.
● Tighten the 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, and do not insert/remove the extended SRAM cassette to/from the
CPU module more than 50 times (IEC 61131-2 compliant) respectively. Exceeding the limit may cause
malfunction.
● After the first use of the product, do not insert/remove the SD memory card to/from the CPU module
more than 500 times. Exceeding the limit may cause malfunction.
● Do not touch the metal terminals on the back side of the SD memory card. Doing so may cause

1.7
Scaling Function
This function performs the scale conversion on digital values within a specified range between a scaling upper limit value and
a scaling lower limit value. This function helps reduce the time taken for creating a scale conversion program.
Operation
The scale conversion is performed for the set 'CH1 Digital value' (Un\G460) using 'CH1 Scaling upper limit value' (Un\G504)
and 'CH1 Scaling lower limit value' (Un\G506), and the value after the scale conversion is used for the D/A conversion. (In the
scale conversion, values after the decimal point are rounded off.)
Concept of scaling setting
The necessary settings for the scaling lower limit value and scaling upper limit value depend on whether the factory default
setting or the user range setting is used for the analog output range.
■When the factory default setting is used for the analog output range
• For the scaling upper limit value, set a value corresponding to the upper limit value of the set analog output value.
• For the scaling lower limit value, set a value corresponding to the lower limit value of the set analog output value.
■When the user range setting is used for the analog output range
• Set a value corresponding to the gain value for the scaling upper limit value.
• Set a value corresponding to the offset value for the scaling lower limit value.
Calculating the scaling value
For D/A conversion, the scaling value is calculated based on the following calculation formulas.
■When the factory default setting is used for the output range
• When the voltage is 1 to 5V, 0 to 5V, or 1 to 5V (extended mode) and the current is 4 to 20mA, 0 to 20mA, or 4 to 20mA
(extended mode)

Outputting the analog values corresponding to the extended part of the output range
When the digital values in the extended part of the extended mode of the output range (the digital values in the range of 32768
to 36767 that correspond to the analog values higher than 20mA/5V) are scaled to the 16-bit data range while the scaling
function is enabled, the analog values corresponding to the extended part can be output.

Within the range of
16-bit signed data
The digital value 27000 corresponds to the analog output voltage 5.5V. Thus, the analog values corresponding to the
extended range can be output by setting 'CH1 Digital value' (Un\G460).
When the scaling function is used, the resolution may be reduced. To perform the D/A conversion to output the analog value
while keeping the resolution, use the shift function. ( Page 23 Shift Function)
Precautions
• When the scaling function is used, the digital value can be set to a value out of the range between the scaling upper limit
value and scaling lower limit value (in the dotted lines in the I/O conversion characteristic graph) before being scaled.
However, use the scaling function within the range of the analog output practical range (in the solid line in the I/O
conversion characteristic graph). If the value exceeds the analog output practical range, the maximum resolution and
accuracy may not fall within the range of the performance specifications.
• The default digital value "0" may not be appropriate, depending on the scaling function setting.
In particular in the examples of when the output range is 0 to 5V, an out-of-range digital value error occurs if 'CH1 Output
enable/disable flag' (Y1) is turned on with the digital value "0". A digital value setting range error (error code: 191H)
occurs and 'Error flag' (XF) turns on, and the ERR LED turns on.
Therefore, set an appropriate digital value within the scaling range before turning on 'CH1 Output enable/disable flag' (Y1).
• When using the user range, note that the scaling lower limit value is equal to the offset value.
• When the scaling function is enabled and the digital value after the scaling conversion is out of the digital setting range, a
digital value setting range error (error code: 191H) occurs and the corresponding check code is stored in 'CH1 Set value
check code' (Un\G400).
• When the scaling function is used while the output range is set to 4 to 20mA (extended mode) or 1 to 5V (extended mode),
the digital values in the extended range may exceed the range of -32768 to 32767 and the setting may be disabled.

Shift Function
1
This function allows adding the set input value shift amount to the digital value.
The analog output value reflects the change in the input value shift amount on a realtime basis. Therefore, fine adjustment
can be easily performed when the system starts.
Operation
When the D/A conversion is performed on the digital value, the value obtained by adding 'CH1 Input value shift amount'
(Un\G480) to 'CH1 Digital value' (Un\G460) is used for the D/A conversion.
When the digital value after the addition exceeds the range as the result of the shift processing, the value is fixed to the lower
limit value or the upper limit value.
When a value is written to 'CH1 Input value shift amount' (Un\G480), the set value is added to the digital input value
regardless of the ON/OFF state of 'Operating condition setting request' (Y9).
Setting procedure
Set a value for "Input value shift amount".

Outputting the analog values corresponding to the extended part of the output range

(the digital values in the range of 32768 to 36767 that correspond to the analog values higher than 20mA/5V) can be output.
The sum of the digital value and the input value shift amount must be within the range of 32768 to 36767.
Ex.
When the output range is set to 4 to 20mA (extended mode), 'CH1 Digital value' (Un\G460) is set to 32000, and 'CH1 Input

■Alert output notification
When 'CH1 Digital value' (Un\G460) is larger than 'CH1 Alert output upper limit value' (Un\G510) or is smaller than 'CH1 Alert
output lower limit value' (Un\G512), either of 'Alert output upper limit flag' (Un\G36) or 'Alert output lower limit flag' (Un\G37),
'Alert output signal' (XE), and the ALM LED turn on to output an alert. In addition, an alarm code (080H or 081H) is stored
in 'Latest alarm code' (Un\G2) when an alert has occurred.
When an alert has occurred, the set value of the alert output upper limit value or the alert output lower limit value is used as
the digital value for the D/A conversion.
When 'CH1 Digital value' (Un\G460) is changed to a value smaller than 'CH1 Alert output upper limit value' (Un\G510) and
larger than 'CH1 Alert output lower limit value' (Un\G512) after an alert has occurred, the analog output value returns to a
normal value. However, 'Alert output upper limit flag' (Un\G36), 'Alert output lower limit flag' (Un\G37), and 'Alert output signal'
(XE) are not cleared.

Clearing an alert
The alert output can be cleared in the following two methods:
After 'CH1 Digital value' (Un\G460) is set to be smaller than 'CH1 Alert output upper limit value' (Un\G510) and larger than
'CH1 Alert output lower limit value' (Un\G512)
• Turning on and off 'Alert output clear request' (YE)
• Turning on and off 'Operating condition setting request' (Y9)
The D/A converter module arranges the following status when an alert output is cleared.
• Clearing 'Alert output upper limit flag' (Un\G36) and 'Alert output lower limit flag' (Un\G37)
• Turning off 'Alert output signal' (XE)
• Turning off the ALM LED
• Clearing the alarm code stored in 'Latest alarm code' (Un\G2)

1.9 Alert Output Function
1.10
Rate Control Function
1
This function allows prevents the sudden change of the analog output value by limiting the increment/decrement of the analog
output value per 1ms.
Operation
When the change amount of 'CH1 Digital value' (Un\G460) is larger than the value set in 'CH1 Increase digital limit value'
(Un\G514) or 'CH1 Decrease digital limit value' (Un\G516), this function changes 'CH1 Digital value' (Un\G460) by the limit
values set for each digital limit value.
The increment/decrement values per 1ms are set for 'CH1 Increase digital limit value' (Un\G514) and 'CH1 Decrease digital
limit value' (Un\G516). However, the actual update cycle of the output value of the corresponding channel is (1ms  Number
of conversion enabled channels).
Therefore, the analog output value increases or decreases per update cycle as follows:
First time: The D/A conversion value of the increase/decrease digital limit value
Second time or later: The D/A conversion value of (Increase/decrease digital limit value  Number of conversion-enabled
channels)

Precautions
1
• The setting of the shift function is enabled during the rate control.
• When the alert output function is enabled, the alert determination is performed to the set 'CH1 Digital value' (Un\G460).
Note that an alert does not occur at the timing when the digital value changed by the rate control function exceeds the
upper/lower limit value.
• The rate control does not function during the analog output test for when the CPU module is in the STOP state.
• With the analog output HOLD/CLEAR setting set to other than Previous value, the analog output changes when the CPU
module is in the STOP state but the rate control does not function.
• When the CPU module status changes while the D/A conversion and D/A output are enabled and the analog output HOLD/
CLEAR setting is set to CLEAR, the rate control function operates as follows:
When the CPU module status changes from RUN to STOP (error), the rate control does not function. When the CPU
module status changes from STOP (error) to RUN, the rate control functions.
• While the rate control is enabled, the analog output is restarted from the offset value when the CPU module status is
changed from STOP (error) to RUN with the D/A conversion enabled, the D/A output enabled, and the analog output set to
HOLD.
• When the D/A conversion is enabled and the D/A output is disabled, the rate control does not function.
• When a value out of the setting range is written to 'CH1 Digital value' (Un\G460) during the rate control, the rate control is
performed with the upper or lower limit value of the setting range.
In addition, the check result is stored in 'CH1 Setting value check code' (Un\G400).
• When the external power supply is turned off during the rate control, the rate control does not function and the analog
output value changes to 0V/0mA. When the external power supply is recovered, the rate control is restarted from the offset
value.

External Power Supply Disconnection Detection
Function
X signals used in this function differ between CH1 to CH8 (used for the R60DA8-G and the R60DA16-G) and
CH9 to CH16 (used only for the R60DA16-G).
• CH1 to CH8: 'External power supply READY flag (CH1 to CH8)' (X7)
• CH9 to CH16: 'External power supply READY flag (CH9 to CH16)' (X17)
This section describes examples for CH1 to CH8. When using CH9 to CH16, regard X7 as X17.
This function detects that the external power supply 24VDC is not supplied or the supply stops.
When the external power supply disconnection is detected, 'External power supply READY flag (CH1 to CH8)' (X7) turns off,
and the analog output value becomes 0V/0mA regardless of the other settings.
Operation
When the external power supply is not input or when 200ms has not yet elapsed after the power supply is input, the power
supply is regarded as disconnected and 'External power supply READY flag (CH1 to CH8)' (X7) turns off.
When the external power supply input stops, the external power supply is regarded as disconnected and 'External power
supply READY flag (CH1 to CH8)' (X7) turns off.
Two external power supplies are provided for the R60DA16-G. One is for CH1 to CH8 and the other is for CH9
to CH16. The status of each external power supply (the power is being supplied or not) is indicated by
'External power supply READY flag (CH1 to CH8)' (X7) and 'External power supply READY flag (CH9 to
CH16)' (X17).
Even when only one of the two external power supplies is on, the D/A conversion is performed in the channels
of the group where the external power is being supplied (CH1 to CH8 or CH9 to CH16) without changing the
conversion cycle.
Precautions
When the external power supply does not satisfy the requirements of the performance specifications, the external power
supply is regarded as disconnected.
For the performance specifications of the external power supply, refer to the following.

■Disconnection detection
A disconnection can be detected when the analog output range is 4 to 20mA and 'CH1 D/A conversion enable/disable setting'
(Un\G500) is set to D/A conversion enabled (0).
The R60DA8-G requires 8ms and the R60DA16-G requires 16ms at a maximum to detect a disconnection.
■Operations performed when a disconnection is detected
When a disconnection is detected, the disconnection is notified by turning on 'Disconnection detection flag' (Un\G38),
'Disconnection detection signal' (XD), and the ERR LED.
In addition, an error code (1C4H) is stored in 'Latest error code' (Un\G0).
Even if the disconnection cause is eliminated, the analog output does not restart automatically to prevent an incorrect output.
To restart the analog output, check 'CH1 Digital value' (Un\G460) and turn on and off 'Error clear request' (YF). According to
the status of 'CH1 Output enable/disable flag' (Y1), the analog output restarts.
When the analog output restarts, 'Disconnection detection flag' (Un\G38) of the corresponding channel is cleared. When the
analog output of all the channels restarts, 'Disconnection detection signal' (XD) is cleared.

Interrupt Function
The D/A converter module executes the interrupt program of the CPU module when an interrupt factor such as a
disconnection or alert output is detected.
For the D/A converter module, the maximum number of interrupt pointers available is 16 per module.
Operation
■Detecting an interrupt factor
When an interrupt factor occurs, an interrupt request is sent to the CPU module at the same time as 'Interrupt factor detection
flag [n]' (Un\G4 to Un\G19) is turned to Interrupt factor (1).
■How to reset an interrupt factor
When Reset request (1) is set to 'Interrupt factor reset request [n]' (Un\G156 to Un\G171) corresponding to the interrupt factor,
the specified interrupt factor is reset and 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19) changes to No interrupt factor
(0).
Setting procedure
To use the interrupt function, set "Condition target setting", "Condition target channel setting", "Interrupt factor transaction
setting", and "Interrupt pointer" with the engineering tool. After completing the settings, write the project to enable the settings.

• Multiple interrupt pointers can also share the same setting of 'Condition target setting [n]' (Un\G232 to
Un\G247). When interrupts with the same settings occur in 'Condition target setting [n]' (Un\G232 to
Un\G247), the interrupt program is executed in order of the priority of the interrupt pointers. For the priority
of the interrupt pointers, refer to the following.

requests that have the same interrupt factor are sent to the CPU module if alerts are issued in multiple
channels. In this case, the CPU module executes multiple interrupt programs and judges that the program
cannot be normally finished due to the scan monitoring function, and a CPU module error may occur. When

Backing up, Saving, and Restoring Offset/Gain
Values
1
The D/A converter module makes it possible to back up, save, and restore the offset/gain values of the user range setting.
• Back up: Creates a module-specific backup parameter and saves offset/gain values.
• Save: Saves the offset/gain information, registered in this module by making the offset/gain setting, in the CPU module.
• Restoration: Writes the information backed up and saved in the CPU module to this module.
In the event that the D/A converter module fails and needs to be replaced, the offset/gain values of the failed D/A converter
module can be restored onto the new D/A converter module.
However, if the offset/gain values are saved and restored, the accuracy after the restoration decreases by approximately three
times compared to that before the restoration. Reconfigure the offset/gain setting when required.
Only when the model where the offset/gain values are to be saved and the model where the offset/gain values are to be
restored are the same, the offset/gain values can be saved and restored. Each procedure differs depending on whether a
module-specific backup parameter is used or not.
When the module-specific backup parameter is used
Offset/gain values are automatically restored when the failed module is replaced with a new one using the online module
change. For details on the online module change, refer to the following.
 MELSEC iQ-R Online Module Change Manual
Details of the module-specific backup parameter
A module-specific backup parameter is a file created in an SD memory card or the data memory of the control CPU. The
contents of the parameter are the offset/gain value of the user range stored in the non-volatile memory of the D/A converter
module.
The file name of a module-specific backup parameter is determined as follows based on the start I/O number of the D/A
converter module.
UBPmmmnn.BPR
• mmm indicates a value calculated by dividing the module I/O No. by 10H (3 digits in hexadecimal).
• nn indicates a consecutive number of the module-specific backup parameters for each module and fixed to 00.

offset/gain values of the user range are restored based on the settings of the
buffer memory areas (Save data type, CH1 Factory default setting offset value
to CH16 User range setting gain value). At this timing, module-specific backup
parameters are updated.
When the G(P).OGSTOR instruction is executed in the normal mode
When the G(P).OGSTOR instruction is executed in the normal mode, the
offset/gain values of the user range are restored. At this timing, modulespecific backup parameters are updated.
When a new module is recognized after the online module change
When a new module is mounted and recognized after the online module
change, the offset/gain values of the user range are restored. At this timing,
module-specific backup parameters are updated.
When no module-specific backup parameter exists in the data memory of the control CPU and a module-specific backup
parameter needs to be created with the current setting, change the mode of the D/A converter module to the offset/gain
setting mode and turn on 'User range write request' (YA). A module-specific backup parameter is created with the current
setting of the flash memory.
■Precautions
If the creation of a module-specific backup parameter fails because the data memory of the control CPU does not have
sufficient free space or the module-specific backup parameter is being used, a module-specific backup parameter creation
error (error code: 17E1H) occurs.
Reading of module-specific backup parameters
To read a module-specific backup parameter and restore offset/gain values, set "Auto restore of Offset/gain setting with the
module change" of the module parameter to "Enable" in advance.
Navigation window  [Parameter]  [Module Information]  Module model name  [Module Parameter]  "Application
setting"  "Online module change"
■Reading timing
Module-specific backup parameters are read when a new module is mounted and recognized after the online module change.
When the programmable controller is powered off and the module is replaced with a new one, module-specific backup
parameters are not read.
■Precautions
When the module-specific backup parameter for the target slot does not exist in an SD memory card or the data memory of
the control CPU, the subsequent restoration of the offset/gain values is not performed. If the offset/gain values cannot be
restored even though the module-specific backup parameter exists, a module-specific backup parameter restore error (error
code: 17E0H) occurs.
Restoration of the offset/gain values of the user range
When reading module-specific backup parameters are completed with no errors, the values are converted (restored) into the
offset/gain values of the user range for the new module, and stored in the non-volatile memory. At the same timing, the
module-specific backup parameter in the data memory of the control CPU is updated with the setting of the new module.

Q Compatible Mode Function
This function allows setting the same buffer memory addresses of the A/D converter module as the buffer memory addresses
of the MELSEC-Q series module.
This compatibility makes it possible to reuse sequence programs that have exhibited high performance on the MELSEC-Q
series modules.
The following table lists the compatible modules of the MELSEC-Q series.
MELSEC iQ-R series D/A converter module
Compatible D/A converter module
R60DA8-G
Q66DA-G
The R60DA16-G does not support the Q compatible mode function.
Operation
Only the buffer memory assignment is changed in the Q compatible mode.
• The I/O signal assignment is the same as that of the R mode. Some signals have been changed. However, the signals that
change the module operation maintain the compatibility. Therefore, when a MELSEC-Q series sequence program is
diverted, a significant modification of the program is not required. The following table shows a difference between the
R60DA8-G and Q66DA-G.

• When a MELSEC-Q series sequence program is diverted, check digital values and the operation timing and
modify the sequence program if necessary because the specifications such as the resolution and update
timing are changed.
• When a MELSEC-Q series sequence program is diverted and an error code is set as the operating
condition or interlock condition, the program does not operate normally.
• When the Q compatible mode function is enabled, a program that uses FB or labels cannot be created.
When FB or labels is used, create a program in the R mode.

■Disconnection detection flag status
• When a disconnection is detected, Disconnection detection (1) is stored in 'Disconnection detection flag' (Un\G38)
corresponding to each channel.
• When a disconnection is detected in any channel, 'Disconnection detection signal' (XD) turns on.
■Clearing Disconnection detection flag
Even if the disconnection cause is eliminated, the analog output does not restart automatically to prevent an incorrect output.
To restart the analog output, check CH Digital value and turn on and off 'Error clear request' (YF). According to the status of
'CH Output enable/disable flag' (Y1 to Y8, Y11 to Y18), the analog output restarts.
When the analog output restarts, the disconnection detection flag of the corresponding channel is cleared.

The check target is 'CH1 Digital value' (Un\G460).
When a digital value out of the setting range is written, one of the following check codes is stored.
Check code
Description
000FH
A digital value exceeding the setting range has been written.
00F0H
A digital value falling short of the setting range has been written.
00FFH
A digital value falling short of the setting range and a digital value exceeding the setting range have been written.
This check code may be stored when a check code is not reset.
Once the check code is stored, the code is not reset even when the digital value falls within the setting range.
To reset the check code, rewrite the digital value to a value within the setting range and turn on and off 'Error clear request'
(YF).
When the scaling function is used, the value of 'CH1 Digital value' (Un\G460) which has undergone a scale conversion is
checked. Note that some errors may be observed in the target digital value for a check code to be stored due to the
calculation error of scale conversion when a scale-converted value exceeds the setting range.

The available setting range and practical range of when the scaling function is enabled differ depending on the setting of the scaling
upper limit value and scaling lower limit value.
When a value out of the available setting range is written, the D/A conversion is performed with the upper or lower limit value
of the available setting range.
A check code is stored in 'CH1 Set value check code' (Un\G400) and a digital value setting range error (error code: 191H) is
stored in 'Latest error code' (Un\G0).
When the output range is set to 4 to 20mA (extended mode) or 1 to 5V (extended mode) and the scaling
function is disabled, the analog output value ranges as shown below.
• 4 to 20mA (extended mode): 0 to 20.48mA
• 1 to 5V (extended mode): 0 to 5.12V
To output 22mA or 5.5V, use the scaling function or shift function.

■Setting range
The setting range is from -32768 to 32767. In the channel where a set value does not satisfy the condition "alert output upper
limit value > alert output lower limit value", an alert output upper/lower limit value inversion error (error code: 1B1H) occurs.
When 'CH1 Alert output setting' (Un\G508) is set to Disable (1), the setting of 'CH1 Alert output lower limit value' (Un\G512) is
ignored.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9).
■Default value
The default value is 0 for all channels.
■Precautions
When the shift function is used, always set a value in consideration of 'CH1 Input value shift amount' (Un\G480).

■Enabling the setting
Turn off and on 'Channel change request' (YB).
■Default value
The default value is 0H for all channels.
When the offset/gain setting is configured from the offset/gain setting window of an engineering tool, the
setting is performed properly on the window. Therefore, a program is not required to perform the setting.
When a sequence program used for the MELSEC-Q series D/A converter module is utilized to configure the
offset/gain setting, check that an appropriate value has been set in this area.
For the sequence programs for the MELSEC-Q series D/A converter module, refer to the following.
