[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. Incorrect output or malfunction due to a communication failure may result in an accident.

● 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 setting values in the buffer memory are being written to the flash ROM in the module. 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 can cause malfunction or failure of the module.

● When changing the operating status of the CPU module (such as remote RUN/STOP) from the external device, select "Do Not OPEN in Program" for the "Open Method Setting" in the module parameter. The communication line will be closed when "OPEN in Program" is selected and the remote STOP is executed from the external device. Consequently, the CPU module cannot reopen the communication line, and the external device cannot execute the remote RUN.

● 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.

Precautions for when the remote head module has been mounted

When the D/A converter module has been mounted on the remote head module, set whether to hold or clear the analog

output value that has been output when the host station is disconnected with "CPU error output mode setting" of the module

parameter.

The following describes the settings required for using "CPU error output mode setting".

• Enable the station-based block data assurance for cyclic data on the sending side.

• To hold the analog output value, set "CPU error output mode setting" to "Hold". The analog output HOLD/CLEAR function

setting is disabled.

This setting is enabled for each module and cannot be set for each channel. To match the output status of when a stop error

occurs or the CPU module is in the STOP state and that of when the host station is disconnected, set "Analog output HOLD/

CLEAR setting" to the same value in all the channels.

When a digital value that is out of the setting range is written, a digital value setting range error (error code: 191H) occurs

and the corresponding check code is stored in 'CH1 Setting value check code' (Un\G400).

Operation

By forcibly turning on 'CH1 Output enable/disable flag' (Y1) when the CPU module is in the STOP state, the analog output

value is changed from the offset value to the D/A-converted analog output value.

The following figure shows the relation between 'CH1 Output enable/disable flag' (Y1) and the analog output value of the CPU

module in the STOP state when the analog output HOLD/CLEAR setting is set to CLEAR (0).

*1 'CH1 Output enable/disable flag' (Y1) turns off when the status of the CPU module is changed into STOP. *2 By forcibly turning on 'CH1 Output enable/disable flag' (Y1), the analog output value is changed from the offset value to the D/A-

converted analog output value.

Setting procedure

To perform an analog output test, configure the settings in the device test of the engineering tool following the procedure

shown below.

1. Set 'CH1 D/A conversion enable/disable setting' (Un\G500) of the buffer memory to D/A conversion enabled (0).

2. Turn on 'Operating condition setting request' (Y9).

3. Check that 'Operating condition setting completed flag' (X9) turns off, and turn off 'Operating condition setting request'

(Y9).

4. Set the digital value equivalent to the analog value to be output for 'CH1 Digital value' (Un\G460) in the buffer memory.

5. Turn on 'CH1 Output enable/disable flag' (Y1).

Digital value used for D/A conversion

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. The program for scale conversion can be omitted.

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.)

When the relation between the set upper limit value and lower limit value is Scaling lower limit value > Scaling upper limit

value, the scale conversion can be performed according to a negative slope.

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 equations.

■When the factory default setting is used for the output range

• When the voltage is 1 to 5V or 0 to 5V and the current is 4 to 20mA or 0 to 20mA

• When the voltage is -10 to 10V

■When the user range setting is used for the output range

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 characteristics 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 characteristics 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 lights.

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 Setting

value check code' (Un\G400).

• The scaling function is enabled only for the normal output. When the scaling function is enabled while the wave output

function is used, a scaling setting error in wave output mode (error code: 0B1H) occurs and 'Alert output signal' (XE) turns

on.

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 of -32768 to 32767 as the result of the shift processing, the value

is fixed with the lower limit value (-32768) or the upper limit value (32767).

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 the shift amount to "Input value shift amount".

Precautions

• Based on the digital value on which the shift-and-add is performed, the alert output function, scaling function, and rate

control function are executed.

• When the value obtained by adding 'CH1 Input value shift amount' (Un\G480) to 'CH1 Digital value' (Un\G460) 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 Setting value check code' (Un\G400).

• The shift function is enabled only for the normal output. When a value other than 0 is set in 'CH1 Input value shift amount'

(Un\G480) while the wave output function is used, an input value shift amount setting error in wave output mode (alarm

code: 0B2H) occurs and 'Alert output signal' (XE) turns on. Although the wave output continues, 'CH1 Input value shift

amount' (Un\G480) is not added to the wave data to be output.

• Even though 0 is set for 'CH1 Input value shift amount' (Un\G480) after an input value shift amount setting error in wave

output mode has occurred, 'Alert output signal' (XE) does not turn off. Turn on and off 'Alert output clear request' (YE) to

turn off 'Alert output signal' (XE). By this operation, 'Alert output signal' (X8) and the ALM LED turn off, and Latest alarm

code is cleared.

Operation

■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 a warning

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)

1.10 Rate Control Function

The increment/decrement of the analog output value per 80s is restricted to prevent the sudden change of the analog output

value.

When the inter-module synchronization function is enabled, the rate control function cannot be used.

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 80s 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 (80s  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)

• 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 Analog output HOLD/CLEAR setting set to a value other than HOLD, the analog output value changes when the CPU

module is in the STOP state but the rate control function 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.

• When the CPU module status is changed from STOP (error) to RUN while the D/A conversion is enabled, the D/A output is

enabled, analog output is set to HOLD, and the rate control is enabled, the analog output is restarted from the offset value.

• 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.

• The rate control function is enabled only for the normal output. When the rate control function is enabled while the wave

output function is used, a rate control setting error in wave output mode (alarm code: 0B3H) occurs and 'Alert output

1.11 External Power Supply Disconnection Detection

Function

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' (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' (X7) turns off.

When the external power supply input stops, the external power supply is regarded as disconnected and 'External power

supply READY flag' (X7) turns off.

Precautions

When the external power supply does not satisfy the requirements of the performance specifications, the external power

supply is regarded as disconnected.

The R60DA4 and R60DAI8 can detect a disconnection by monitoring the analog output value. This function is enabled only

when the analog output range is 4 to 20mA. A disconnection can be detected for each channel.

Operation

■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).

■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.

1.13 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" in the engineering tool. After completing the settings, write the project to enable the settings.

• If 'Condition target setting [n]' (Un\G232 to Un\G247) is Disable (0), an interrupt request is not sent to the

CPU module.

• To reset the interrupt factor, set Reset request (1) until 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19)

changes to No interrupt factor (0).

• Resetting interrupt factors is executed only when 'Interrupt factor reset request [n]' (Un\G156 to Un\G171)

changes from No reset request (0) to Reset request (1).

• 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.

 MELSEC iQ-R CPU Module User's Manual (Application)

• When All channels (0) is set for 'Condition target channel setting [n]' (Un\G264 to Un\G279) and an interrupt

detection target for each channel is set to 'Condition target setting [n]' (Un\G232 to Un\G247) such as Alert

output flag (2), the interrupt 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 at a time

and judges that the program cannot be normally finished due to the scan monitoring function of the CPU

module, and a CPU module error may occur. When a CPU error occurs, refer to the following.

This function registers the prepared wave data (digital input value) in the D/A converter module and continuously outputs the

data (analog value) in the set conversion cycle. A faster and smoother control than a program is achieved by the automatic

output of the control wave data registered in the D/A converter module for the analog (torque) control such as pressing

machines and injection molding units. The control can be executed only by registering the wave data to the D/A converter

module. Therefore, the program-less control is available for the repeat control such as the line control, and man-hours for

programming can be reduced.

set for the output count.

When the wave pattern output count is set to three

The following describes the repeat control in which the same wave pattern is output repeatedly from the D/A converter

module.

■When the digital input values are same for the start point and the end point

An end point of a wave pattern overlaps with the start point of the wave pattern of the next iteration in the D/A converter

module's processing; therefore, the end point is not output in analog. The analog output of the wave pattern end point varies

as follows depending on the setting of 'CH1 Wave pattern output repetition setting' (Un\G530).

• Limited repetition

When a value of 2 to 32767 is set to 'CH1 Wave pattern output repetition setting' (Un\G530), the digital input value of the end

point is not output in analog till the wave pattern of the final iteration output. After the digital input value of the end point is

output in analog at the wave pattern of the final iteration output, the value is output in analog according to the setting in 'CH1

Output setting during wave output stop' (Un\G524).

D/A conversion is enabled varies depending on the status of 'CH1 Output enable/disable flag' (Y1) as shown below.

• When 'CH1 Output enable/disable flag' (Y1) is off: The offset value is output.

• When 'CH1 Output enable/disable flag' (Y1) is on: The value set in 'CH1 Output setting during wave output stop' (Un\G524)

is output.

With the wave output function being used, only when the wave output is stopped in all the channels (Wave

output stop (0) is set to CH Wave output status monitor in all the channels), the parameter setting can be

enabled by turning on and off 'Operating condition setting request' (Y9).

When 'Operating condition setting request' (Y9) is turned on and off with a channel being set to a value other

than Wave output stop, an alert occurs. In addition, an alarm code (0B0H) is stored in 'Latest alarm code'

■Registering procedure

1. Use "Create Wave Output Data" of the engineering tool to write the parameter settings of the wave data and the wave

output function to the file register (ZR) of the CPU module of the master station.

2. Use the JP.REMTOD instruction to transfer the parameter settings from the file register (ZR) to the D/A converter module

mounted together with the remote head module.

In this case, register the parameter settings of the wave data and the wave output function first, and then change the setting of

'CH1 D/A conversion enable/disable setting' (Un\G500).

3. Perform operations such as requesting the start or stop of the wave output with a program.

■Program

The following describes a program that transfers the parameter settings from the file register (ZR) to the D/A converter

module mounted together with the remote head module using the JP.REMTOD instruction. The program in this section is for

the case when ZR0 is set as the start device and the parameter settings are written using "Create Wave Output Data". The file

register (ZR) to which the parameter settings are written varies depending on the specified start device. For the file register

(ZR) to which the settings are written, refer to the following.  MELSEC iQ-R Analog-Digital Converter Module/Digital-Analog Converter Module Function Block Reference

When the CPU module status is changed during the wave output, the operation of the module varies depending on the setting

of the analog output HOLD/CLEAR function as shown below.

■For HOLD setting

When the CPU module status is changed from RUN to STOP, the analog output value at the change is held and the wave

output pauses. When the CPU module status is changed from STOP to RUN, the wave output resumes. To prevent the wave

output from resuming, set Wave output stop request (0) to 'CH1 Wave output start/stop request' (Un\G462) after changing the

CPU module status from RUN to STOP.

At the timing when the CPU module status is changed from STOP to RUN, the module parameter setting is reflected.

At this time, the same processing as the one when 'Operating condition setting request' (Y9) is turned on and off in the D/A

converter module is executed. Therefore, if the CPU module status is changed from STOP to RUN while 'CH1 Wave output

status monitor' (Un\G462) is in a state other than Wave output stop (0), an operating condition setting error except for wave

output stop (alarm code: 0B0H) occurs.

To clear the alarm, turn on and off 'Alert output clear request' (YE).

When 0 to 5V is set to the output range

When the value to be output is out of the output range, an error occurs. The error code (191H) is stored in 'Latest error code'

(Un\G0), 'Error flag' (XF) turns on, and the ERR LED turns on. When an error (error code: 191H) occurs during the wave

output, the analog output value becomes as follows.

• If the value to be output is greater than the maximum value of the output range, the maximum value of the output range is

output in analog.

• If the value to be output is smaller than the minimum value of the output range, the minimum value of the output range is

output in analog.

When an error (error code: 191H) has occurred, correct the digital input value of the wave data so that the value is within the

output range. Then, turn on and off 'Error clear request' (YF).

In addition, when the digital input value out of the range is set and an error (error code: 191H) has occurred, correct the

value to the one within the range and turn on and off 'Error clear request' (YF).

To check the buffer memory address where the wave data with the value out of the range is registered, use Wave output

digital value out-of-range address monitor.

wave output stop (the wave output stops). The wave output does not resume even when the external power supply is turned

on.

To resume the wave output, check the D/A converter module and external devices after turning on the external power supply,

and set Wave output start request (1) to 'CH1 Wave output start/stop request' (Un\G462).

The wave output step action function is executed as follows.

Change the value in 'Step action wave output request' (Un\G188) from OFF (0) to ON (1) to set the wave output status to the

wave output step action. By setting a value in 'CH1 Wave output step action movement amount' (Un\G482) during the wave

output step action, the address moves to the address of the target wave data for the output test. Set the amount for movement

from the current wave data address in 'CH1 Wave output step action movement amount' (Un\G482).

After the movement, the value in 'CH1 Wave output step action movement amount' (Un\G482) is changed to No movement

(0) and the wave data of the target address is output in analog.

The available range for movement by using 'CH1 Wave output step action movement amount' (Un\G482) depends on the

setting values of the wave pattern start address and wave pattern data points. The following shows the available range for

movement.

If a value out of the setting range of the wave pattern data points is set to 'CH1 Wave output step action movement amount'

(Un\G482), the data is processed with the value within the setting range.

Execution of the wave output step action function

To use the wave output step action function, the initial setting for the wave output function must be set in advance. For details

on the initial setting for the wave output function, refer to the following. Page 46 Initial settings of the wave output function

■Switch to the wave output step action status

Switch the wave output status to the wave output step action in the following procedure.

1. Change the value in 'Step action wave output request' (Un\G188) from OFF (0) to ON (1).

2. Check that During wave output step action (3) has been set to CH Wave output status monitor in all the channels

where the D/A conversion is enabled.

To execute the wave output step action, check 'Latest error code' (Un\G0) and the ERR LED to check that no error has

occurred, and set 'Step action wave output request' (Un\G188) from OFF(0) to ON(1). When the value in the parameter

setting of the wave output is not set within the setting range in all the channels where the D/A conversion is enabled, the wave

output step action cannot be executed in all the channels.

■Execution of the wave output step action

After switching the status to the wave output step action status, execute the wave output step action in the following

procedure. Repeating this procedure tests the analog output during the wave output function execution and debugs the wave

output function.

1. Change the value of the target wave data for the wave output step action to any value.

2. Set a value to 'CH1 Wave output step action movement amount' (Un\G482).

Set the following value according to the direction to move.

Movement direction Description Setting value

No movement The buffer memory address of the wave data to be output is not moved. 0

Forward movement The buffer memory address of the wave data to be output is moved in the address increasing

1.15 Inter-Module Synchronization Function

Ex.

This function allows the D/A conversion values to be output at the same timing from multiple modules in which the inter-

module synchronization function is active.

The analog output timing of each module is determined by the inter-module synchronization cycle set with the system

parameter.

Setting procedure

■Setting system parameters

For the setting of the system parameters, refer to the following.  MELSEC iQ-R Inter-Module Synchronization Function Reference Manual

■Setting module parameters

• Output setting during synchronous error

Select whether to continue or stop the synchronization of the D/A converter modules when an inter-module synchronization

cross-cycles processing error (error code: 2600H) or inter-module synchronization signal error (error code: 2610H) occurs.

• Operation mode setting

Select "Normal mode (D/A conversion process)".

• Output mode setting

Select "Normal output mode".

• Analog output HOLD/CLEAR function setting

The operation differs from the one in the normal mode. For the difference of the operations performed depending on the

setting details of the HOLD/CLEAR setting, refer to the following. Page 21 In the synchronization normal output mode

■Setting a synchronization digital value

When the synchronization normal output mode is used, 'CH1 Synchronization digital value' (Un\G9500) is output in analog.

Set 'CH1 Synchronization digital value' (Un\G9500) with an interrupt program.

For the setting of interrupt programs, refer to the following.  MELSEC iQ-R CPU Module User's Manual (Application)

■Setting the inter-module synchronization cycle

Set the inter-module synchronization cycle that establishes the following relation.

(Inter-module synchronization cycle) > (Run time of the inter-module synchronous interrupt program + Sampling cycle)

When the D/A conversion is enabled in CH1 to CH3 and disabled in CH4

Sampling cycle = 80s  3CH = 240s

When the above relation is not established and one of the following operations is performed, an inter-module synchronous

cycle time setting enable lower limit shorter error (error code: 1EA0H) occurs and the inter-module synchronization function

■Inter-module synchronization processing for the D/A converter module

When the D/A converter module is used in the synchronization normal output mode, 'CH1 Synchronization digital value'

(Un\G9500) is imported at the timing when the inter-module synchronous interrupt program is executed and the D/A

conversion is performed in the next inter-module synchronization cycle. By setting 'CH1 Synchronization digital value'

(Un\G9500) to multiple D/A converter modules using the inter-module synchronous interrupt program, the analog output can

be performed from the multiple modules at the same timing.

The following figure shows the inter-module synchronization processing of two D/A converter modules (module A and module

B).

(1) When the inter-module synchronous interrupt program is executed, the D/A converter module imports CH Synchronization digital value.

(2) The analog output is performed in the inter-module synchronization cycle after (1). The digital value to which the D/A conversion is performed is CH

Synchronization digital value set in the previous inter-module synchronization cycle.

(3) The values in CH Synchronization digital value are converted in analog in order of CH1, CH2, and CH3 at the start timing of the inter-module

synchronization cycle and the converted analog values are output sequentially. The values are output in analog from the channel 1 of the module A and the channel 1 of the module B simultaneously.

Page 82

• Outputting of the D/A converter module delays for the output delay time from the inter-module

synchronization cycle. The output delay time is 24.1 to 25.9s.

• When values are output in analog from multiple channels, the analog output is performed in order of the

channel number. Outputting values in analog from each channel delays for the channel switching time after

outputting from the previous channel is completed. The channel switching time is 12.3 to 13.2s.

■Abnormal operation during synchronization

• Operation when a cross-cycles processing occurs

The phenomenon in which the D/A conversion is processed crossing over the inter-module synchronization cycles depending

on the operation timing of the synchronous interrupt program is called Cross cycles. When the phenomenon occurs, an inter-

module synchronization cross-cycles processing error (error code: 2600H) occurs. Whether to continue or stop the operation

of the D/A converter module at the occurrence of an error can be selected with "Output selection error during an inter-module

synchronization" of the module parameter. With the default value, the module continues the operation.

• Operation when a cycle skipping occurs

The phenomenon in which the D/A conversion is not processed during an inter-module synchronization cycle depending on

the operation timing of the synchronous interrupt program is called Cycle skipping. When a cycle skipping occurs, an inter-

module synchronization cycle skipping error (error code: 2601H) occurs. When an error occurs, the D/A converter module

stops the operation regardless of the setting of "Output selection error during an inter-module synchronization" of the module

parameter and the analog output is performed according to the HOLD/CLEAR setting.

• Operation when a synchronization deviation occurs

The phenomenon in which the D/A converter module cannot receive values at the set inter-module synchronization cycle

timing or the module receives values at a timing different from the inter-module synchronization cycle timing is called

Synchronization deviation. When a synchronization deviation occurs, an inter-module synchronization signal error (error

code: 2610H) occurs. Whether to continue or stop the operation of the D/A converter module at the occurrence of an error can

be selected with "Output selection error during an inter-module synchronization" of the module parameter. With the default

value, the module continues the operation.

(1) Because the external power supply is turned off, 0V/0mA is output.

(2) 'External power supply READY flag' (X7) turns on and the analog output is restarted after the next synchronous interrupt program is executed.

*1 Even when 'External power supply READY flag' (X7) is off, the synchronous interrupt program is executed.

To avoid unnecessary changes of 'CH1 Synchronization digital value' (Un\G9500) during the execution of the synchronous interrupt program, set 'External power supply READY flag' (X7) as the interlock condition in the program.

synchronous interrupt program after 'External power supply READY flag' (X7) turns on is executed.

• The inter-module synchronization function does not support the synchronization by each channel.

• When the inter-module synchronization function is enabled, the analog output value does not change even though a value

is set to 'CH1 Digital value' (Un\G460). When the inter-module synchronization function is enabled, the value set to 'CH1

Synchronization digital value' (Un\G9500) is the digital value to be converted in analog.

• When the module is set as a synchronization target and the offset/gain setting mode is set in the operation mode setting, an

inter-module synchronization selection offset/gain setting error (error code: 1EA1H) occurs and the module does not

operate.

• When a mode switching setting value is set for 'Mode switching setting' (Un\G296, Un\G297) and 'Operating condition

setting request (Y9)' is turned on, an inter-module synchronization mode switching request error (alarm code: 0D00H)

occurs, 'Alert output signal' (XE) turns on, and the ALM LED lights. In this case, the mode is not switched and the

synchronization processing continues. To clear 'Alert output signal' (XE) and the generated alarm, turn on and off 'Alert

output clear request' (YE).

• When performing the offset/gain setting, set the module as a synchronization non-target, and switch to the normal output

mode to shift the offset/gain setting mode.

• Dedicated instructions cannot be used.

The following shows the operation when a dedicated instruction is executed.

When the G(P).OFFGAN instruction is executed, an inter-module synchronization mode switching request error (alarm code:

0D00H) occurs.

The G(P).OGLOAD instruction is disabled.

When the G(P).OGSTOR instruction is executed, a G(P).OGSTOR instruction execution error in offset/gain setting mode

(error code: 1860H) is stored in the dedicated instruction completion status.

1.18 Backing up, Saving, and Restoring Offset/Gain

Values

The D/A converter module is capable of backing up, saving, and restoring offset/gain values of the user range.

• Backup: 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 replaced D/A converter module.

In addition, if multiple D/A converter modules are connected on a system, the offset/gain settings in one of the D/A converter

modules can be applied to the other modules.

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 a module-specific backup parameters is used

At the time of replacement by means of online module change, the offset/gain values are automatically restored.

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 flash 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.

■Reading timing

Module-specific backup parameters are read when a new module is mounted and recognized after the online module change.

If the module is replaced with the programmable controller powered off, 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

Upon the successful completion of reading module-specific backup parameters, the values are converted (restored) into the

offset/gain values of the user range for the new module, and stored in the flash memory. At the same time, the module-

specific backup parameter in the data memory of the control CPU is updated with the setting of the new module.

Restrictions on the module-specific backup parameter

The back up and restoration by means of module-specific backup parameters fails in the following cases.

• When the control CPU is not the process CPU

• When replacing the D/A converter module with the programmable controller powered off

• When "Auto restore of Offset/gain setting with the module change" of the module parameter is set to "Disable"

In any of the cases above, back up or restore offset/gain values by the following method. Page 90 When the module-specific backup parameter is not used

When the module-specific backup parameter is not used

Back up or restore offset/gain values by one of the following methods.

• Saving and restoring by dedicated instructions

• Saving and restoring by reading from and writing to the buffer memory

With the method above, offset/gain values can be restored to a new module, or the offset/gain values set in one module can

be applied to the other modules in the same system.

• To restore offset/gain values onto a new replaced module:

1. Save the offset/gain values.

2. Replace the D/A converter module.

3. Restore the offset/gain values.

• To apply the offset/gain values set in one module to the other modules in the same system:

Ex.

When the offset/gain values in module No.1 are applied to modules No.2 to No.4

1. Save the offset/gain values of module No.1.

2. Apply the offset/gain values to modules No.2 to No.4.

Methods for saving and restoring offset/gain values

The offset/gain values can be saved and restored by the following two types of operations.

• Saving and restoring by dedicated instructions

• Saving and restoring by reading from and writing to the buffer memory

■Saving and restoring by dedicated instructions

Use the dedicated instruction G(P).OGLOAD to temporarily save the offset/gain values of the source D/A converter module to

the internal device of the CPU, then use G(P).OGSTOR to write the values to the destination D/A converter module.

Prevent the saved offset/gain setting data from being deleted, by one of the following methods before replacing the modules:

• Use latch settings for the internal device of the destination module.

• Save the data onto an SD memory card. (To write data: use the SP.FWRITE instruction. To read data: use the SP.FREAD

instruction.)

• Store the saved data.

For use of dedicated instructions, refer to the following.  MELSEC iQ-R Programming Manual (Module Dedicated Instructions)

■Saving and restoring by reading from and writing to the buffer memory

Use Save data type setting, CH1 Factory default setting offset value to CH8 User range setting gain value, and 'User range

write request' (YA) to read the offset/gain values from the source D/A converter module. Use the buffer memory again to write

the values to the destination D/A converter module.

The following describes the procedure for using the buffer memory.

• To restore offset/gain values onto a new replaced module:

When offset/gain values are restored onto the source D/A converter module

When the power of the module is off

When offset/gain values are restored onto the destination D/ A converter module

 Set Save data type setting.  Turn on and off 'Operating condition setting request' (Y9).  Save the stored values of Save data type setting and CH1 Factory default setting offset value to CH8 User range setting gain

When replacing modules, prevent the saved offset/gain setting data from being deleted, by one of the

following methods before powering off the module.

• Use latch settings for the internal device of the destination module.

• Save the data onto an SD memory card. (To write data: use the SP.FWRITE instruction. To read data: use

the SP.FREAD instruction.)

• Store the saved data.

1.19 Q Compatible Mode Function

This function controls an operation state with the buffer memory layout of the D/A converter module converted to equivalent of

the addresses of the compatible modules of the MELSEC-Q series.

This compatibility makes it possible to reuse sequence programs that have exhibited high performance on the MELSEC-Q

series analog output modules.

The following table lists the compatible modules of the MELSEC-Q series.

MELSEC iQ-R series analog output module Compatible analog output module

R60DA4 Q64DAN

R60DAV8 Q68DAVN

R60DAI8 Q68DAIN

Operation

Only the buffer memory assignment is changed in the Q compatible mode.

• The I/O signal assignment is the same as the one for the R mode. 'High resolution mode status flag' (X8) of the MELSEC-

Q series is deleted and 'Synchronous output mode flag' (XD) is changed to 'Disconnection detection signal' (XD) and

'Synchronous output request' (YD) is changed to 'Disconnection detection clear request' (YD). However, the signals that

change the module operation maintain the compatibility. Therefore, when the MELSEC-Q series program is diverted, a

significant modification is not required.

• When the MELSEC-Q series program is diverted, check digital values and the operation timing and modify

the program if necessary because the specifications such as the resolution and update timing are changed.

• When the MELSEC-Q series 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 FBs or labels are used, create a program in the R mode.

Setting procedure

1. When adding a new module, select the module whose module name has "(Q)" at the end.

avigation window  [Parameter]  [Module Information]  Right-click  [Add New Module...]

2. Configure the same parameter setting as the one of when the R mode is used.

3. Restart the CPU module after the module parameter is written.

• During the module operation, the mode cannot be switched between the R mode and Q compatible mode.

• The project of the compatible D/A converter module created by GX Works2 can be read with the other

format read function of GX Works3. The read project keeps various settings of the compatible D/A converter

module as the settings of the D/A converter module of the MELSEC iQ-R series. The settings to be kept are

the switch setting, parameter setting, auto refresh setting, and I/O assignment.

2. Click "Target" and set the refresh destination.

• When "Target" is "Module Label"

Set whether to enable or disable the auto refresh by setting "Digital value" to Enable or Disable.

• When "Target" is "Refresh Data Register (RD)"

The transfer destinations of all items are automatically set by setting the start device to "Top Device Name".

• When "Target" is "Device"

Double-click the item to be set to enter the numeric value.

3. Click "Refresh Timing" to set the timing to execute the auto refresh.

Set "Refresh Timing" to "At the Execution Time of END Instruction" or "At the Execution Time of Specified Program".

When "At the Execution Time of Specified Program" is set, double-click "Refresh Group [n] (n: 1-64)" and set a value of 1 to

64.

• When the inter-module synchronization function is used and the refresh target is set to "Specified Device",

the auto refresh destination device must be written into "Inter-module synchronous interrupt function".

• With refresh enabled, the value of the refresh destination takes effect at the timing of refresh which is set up

by the engineering tool. As this happens, the buffer memory is overwritten with the value of the refresh

destination. To change the value of a buffer memory area to be refreshed, change the value of module label

or device at the refresh destination in the program.
