[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.

[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]

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.

Analog output tests can be carried out when the CPU module is in the STOP status.

The following functions are enabled during the analog output test.

• Scaling function (Page 23 Scaling Function)

• Shift function (Page 26 Shift Function)

• Alert output function (Page 28 Alert Output Function)

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

1.7 Scaling 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 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.

This function adds the set input value shift amount to the digital input 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 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.

This function outputs an alert when the digital value is larger than the alert output upper limit value or is smaller than the alert

output lower limit value.

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.
