SAFETY PRECAUTIONS

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

WARNING

CAUTION

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

[Design Precaution]

WARNING

Do not write any data to the "system area" or "write-protect area" of the buffer memory areas in the intelligent function module. Also, do not use any "prohibited to use" signals as an output signal to an intelligent function module from the programmable controller CPU. Doing so may cause malfunction of the programmable controller system.

CAUTION

Do not bunch the control wires or communication cables with the main circuit or power wires, or install them close to each other. They should be installed 100mm or more from each other. Not doing so could result in noise that may cause malfunction.

A - 1

[Installation Precautions]

CAUTION

Use the programmable controller in an environment that meets the general specifications contained in the user's manual of the CPU module to use. Using this programmable controller in an environment outside the range of the general specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the product.

While pressing the installation lever located at the bottom of module, insert the module fixing tab into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing hole as a supporting point. For the Q66AD-DG, secure the module with fixing brackets after installation to the base unit.

When using the Q68AD-G in an environment where they are frequent vibrations, screw the module

to the base unit after installation.

Tighten the screws within the range of specified torque. If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module. Not doing so may cause damage to the module. In the system where a CPU module supporting the online module change is used and on the MELSECNET/H remote I/O stations, modules can be replaced online (during energizing). However, there are some restrictions on replaceable modules and the replacement procedures are predetermined for each module. For details, refer to the chapter of the online module change in this manual.

Do not directly touch the conductive area or electronic components of the module. Doing so may cause malfunction or failure in the module.

A - 2

[Wiring Precautions]

CAUTION

Individually ground the FG terminal of the programmable controller with a ground resistance of 100Ω or less. Not doing so can cause an electric shock or malfunction.

When turning on the power and operating the module after wiring is completed, always attach the terminal cover that comes with the product. There is a risk of electric shock if the terminal cover is not attached.

Tighten the terminal screws within the range of specified torque. If the terminal screws are loose, it may result in short circuits or malfunction. If the terminal screws are tightened too much, it may cause damage to the screw and/or the module, resulting in short circuits or malfunction.

Be careful not to let foreign matter such as sawdust or wire chips get inside the module. They may cause fires, failure or malfunction.

The top surface of the module is covered with protective film to prevent foreign objects such as cable offcuts from entering the module when wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate ventilation.

A - 3

[Starting and Maintenance Precautions]

CAUTION

Do not disassemble or modify the modules. Doing so could cause failure, malfunction injury or fire.

Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module. Not doing so may cause failure or malfunction of the module. In the system where a CPU module supporting the online module change is used and on the MELSECNET/H remote I/O stations, modules can be replaced online (during energizing). However, there are some restrictions on replaceable modules and the replacement procedures are predetermined for each module. For details, refer to the chapter of the online module change in this manual.

Do not install/remove the module to/from the base unit more than 50 times after the first use of the product. (IEC 61131-2 compliant) Failure to do so may cause malfunction.

Do not touch the connector while the power is on. Doing so may cause malfunction.

Be sure to shut off all phases of the external power supply before cleaning or retightening the terminal screws or module fixing screws. Not doing so may cause failure or malfunction of the module. If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damages to the screws and/or the module, resulting in the module falling out, short circuits or malfunction.

Always make sure to touch the grounded metal to discharge the electricity charged in the body, etc., before touching the module. Failure to do so may cause a failure or malfunctions of the module.

OVERVIEW

1 OVERVIEW

This User's Manual describes the specifications, handling and programming methods for the type Q68AD-G channel isolated analog-digital converter module (hereinafter referred to as the Q68AD-G) and type Q66AD-DG channel isolated analog-digital converter module (with signal conditioning function) (hereinafter referred to as the Q66AD-DG), which are used with the MELSEC-Q series CPU modules. The Q66AD-DG is exclusively used for current input. In this manual, the Q68AD-G and Q66AD-DG are collectively referred to as the A/D converter modules.

1.1 Features

(1) Channel isolated

The channels are isolated. The Q66AD-DG is also isolated between the external power supply and channels.

(2) Multi-channel analog input is available.

SYSTEM

OVERVIEW

CONFIGURATION

SPECIFICATIONS

(a) By using a single Q68AD-G, analog voltage or current inputs of 8 channels are

available.

(b) A single Q66AD-DG allows connection of 2-wire transmitters of 6 channels.

It has an input range for analog current, in addition to connections to 2-wire transmitters.

(3) Power supply to 2-wire transmitter (Q66AD-DG only)

Supplying power to the 2-wire transmitter, the Q66AD-DG does not require the power supply for the 2-wire transmitter. Supply power can be switched ON/OFF channel-by-channel by the A/D conversion enable/disable setting.

(4) Module protection provided by short-circuit protection circuit

(Q66AD-DG only)

If an excessive current flows into the module due to a short circuit of the wiring, the short-circuit protection circuit limits the current to within 25 to 35mA, protecting the module.

(5) Analog input check by check terminals (Q66AD-DG only)

Measurement of a voltage at the check terminals allows the mA of the 2-wire transmitter output to be checked without the wiring being disconnected.

OVERVIEW

(6) High accuracy

The reference accuracy *1 is as high as ±0.1% and the temperature coefficient*2 is as high as ±71.4ppm/°C.

*1 Accuracy of offset/gain setting at ambient temperature

*2 Accuracy per temperature change of 1°C

Example) Accuracy when the temperature varies from 25 to 30°C

0.1% (reference accuracy) + 0.00714 %/°C (temperature coefficient) 5°C (temperature variation difference) = 0.1357%

(7) Changing the input range

The input range*3 can easily be set from the GX Developer.

*3 Input range refers to the type of offset/gain settings. The most frequently used range is set as the

default but the user can also set the offset/gain.

(8) A/D conversion system

There are the following five A/D conversion systems.

(a) Sampling processing

Analog input values are converted into digital values one by one on a channel basis and the digital output value is output at every conversion.

(b) Averaging processing

1) Time averaging A/D conversion is averaged in terms of time on a channel basis and a digital average value is output.

2) Count averaging A/D conversion is averaged in terms of count on a channel basis and a digital average value is output.

3) Move averaging The specified number of digital output values measured per sampling time are averaged.

A digital output value is smoothed according to the preset time constant.

*1 Refer to Section 3.2.1 for the details of the A/D conversion system.

1 - 2

(9) Input signal error detection function

The voltage/current outside the setting range is detected.

(10)Warning output

There are the following two warning outputs.

(a) Process alarm

A warning is output if a digital output value falls outside the setting range.

(b) Rate alarm

A warning is output if the varying rate of a digital output value falls outside the preset varying rate range.

*1 Refer to Section 3.2.4 for details on warning output.

(14)Easy settings using GX Configurator-AD

A/D conversion values can be converted to percentage values (%) in the preset range and be loaded into the buffer memory. This function can reduce the time required for programming. (Refer to Section 3.2.6.)

Furthermore, the following operations can be processed by using sequence programs. (Note that these operations are possible for the modules of the same model only.) (Refer to Chapter7.)

• Transferring the offset/gain set values to the replacement A/D converter module

• Transferring the offset/and gain set values to another A/D converter module mounted on the other slot

GX Configurator-AD, dedicated instruction (G(P).OFFGAN) or mode switching setting allows a shift to the offset/gain setting mode easily.

Using GX Configurator-AD which is sold separately, sequence programs can be reduced since settings of the A/D converter module can be made on the window. Also, the set status or operating status of the module can be checked easily.

can be created automatically from the set intelligent function module parame-

A FB ter, and can be used in sequence programs.

*1 FB is the function for making a circuit block used in a sequence program repeatedly a part (FB) to

use it in the sequence program. This function can improve the efficiency of program development and minimize program bugs to improve program qualities.

The reference accuracy is the accuracy at the ambient temperature for offset/gain setting. The temperature coefficient is the accuracy per temperature variation of 1°C. The reference accuracy is the accuracy relative to the maximum digital output value. Even if you change the offset/gain setting or input range to change the input characteristic, the reference accuracy and temperature coefficient do not change and are kept within the ranges given in the performance specifications.

3.2.1 A/D conversion methods

(1) Sampling processing

A/D conversion is performed successively for analog input values, and the converted digital output values are stored in the buffer memory. The sampling processing time varies depending on the number of channels used (number of channels set as A/D conversion enable).

Sampling processing time = No. of channels used 10 (ms)

Example) When setting 6 for the number of channels used

6 10 = 60 (ms)

(2) Averaging processing

(a) Time averaging

A/D conversion is made for the preset period of time, the sum of values other than the maximum and minimum values is averaged, and the result is stored into the buffer memory. The processing count within the set time varies depending on the number of channels used (number of channels set as A/D conversion enable).

Processing count = Set time/(No. of channels used 10) (times)

Example) When setting 6 for the number of channels used, and 500ms for the

set time 500/(6 10) = 8.333 (times) Drop the fractional part.

(b) Count averaging

A/D conversion is made the preset number of times, the sum of values other than the maximum and minimum values is averaged, and the result is stored into the buffer memory. The time required for the count-based average value to be stored into the buffer memory varies depending on the number of channels used (number of channels set as A/D conversion enable).

Processing time = Set count (No. of channels used 10) (ms)

Example) When setting 5 (times) for the average processing count

5 6 10 = 50 (ms)

The specified count of digital output values imported per sampling time are averaged to find a value, which is then stored into the buffer memory. Since average processing is performed with data shifted per sampling, the most recent digital output value is obtainable.

(7) How to set an input signal error detection upper/lower limit values

Set input signal error detection upper/lower limit values based on the input signal error detection setting value (input signal error detection upper/lower limit setting values). (Set the values in the unit of 1 (0.1%)). The input signal error detection setting value is reflected to both the input signal error detection upper and lower limit values by default. To detect input signal errors using only an upper limit value or lower limit value, or to individually set an upper limit value and a lower limit value, refer to (9) in this section.

(a) Input signal error detection upper limit value

This value is calculated as follows: Gain value + {Full input range (Gain value - Offset value) detection setting value (Input signal error detection upper limit setting value)} A value equal to or greater than the gain value can be set. A setting value (%) can be calculated by the following formula.

(b) Input signal error detection lower limit value

This value is calculated as follows: Lower limit value of the input range - {Full input range (Gain value - Offset value) Input signal error detection setting value (Input signal error detection lower limit setting value)} A value equal to or smaller than the lower limit value of the input range can be set. A setting value (%) can be calculated by the following formula.

to the maximum value (16000/12000/4000) of the digital output value. The setting range is -32768 to 32767 (-3276.8% to 3276.7%).

(d) The setting range of the rate alarm warning detection period is 10 to 5000ms.

When the period is set to 5000ms, the digital values are compared at intervals of 5 seconds to detect the varying rate.

(e) The rate alarm is judged by converting the rate alarm upper/lower limit value into

the digit value per rate alarm warning detection period. The expression for the value used to make judgment per rate alarm warning detection period is as follows.

Value used to make judgment per rate alarm warning detection period [digit] =rate alarm upper limit value or lower limit value 0.001 maximum value of the digital output value rate alarm warning detection period 1000

Example

In channel 1, when the following:

• Upper limit value of change rate: 30%/s (300 is stored in buffer memory)

• Maximum digital output value: 16000

• Rate alarm warning detection period: 10ms

are set, a value [digit] used at every rate alarm warning detection period can be calculated as follows: 300 0.001 16000 10 1000=48(digit)

Therefore, the current value is compared with the previous value every 10ms in channel 1, and whether a difference of 48 (digit) or more is identified between them or not is determined.

(f) The rate alarm is useful to watch the varying rate of the digital output value in a

limited range.

3.2.6 Scaling Function

(1) With this function, A/D conversion values are converted to rate values and loaded into

the buffer memory.

(2) A digital value stored in CH digital output value (Un\G11 to Un\G18) is converted to

a value in the range set by CH scaling upper/lower limit value (Un\G62 to Un\G77). The converted value is stored in CH scaling value storage area (Un\G54 to

Un\G61).

(3) The scaling function is used for processed values when using the averaging

processing or primary delay filter.

(4) The setting of CH scaling upper/lower limit value (Un\G62 to Un\G77) varies

depending on whether to use the factory default range setting or the user range setting for the input range.

(a) When using the factory default setting for the input range

Set a value that should correspond to the upper limit of digital output as the scaling upper limit value, and a value that should correspond to the lower limit as the scaling lower limit value.

For the Q66AD-DG, the A/D conversion enable/disable setting also acts as the ON/ OFF setting of the supply power to the 2-wire transmitter. Note that power is supplied to only the 2-wire transmitters whose channels use input

ranges of "4 to 20mA (2-wire transmitter input): 0 (2-wire transmitter input): A

H" or "User range setting (2-wire transmitter input): FH".

No power is supplied when any other input range is used.

(2) It is necessary to set the operating condition setting request (Y9) to ON/OFF in order

to validate the A/D conversion enable/disable setting. (Refer to Section 3.3.2.)

A/D conversion completed flag is set to 1. A/D conversion completed flag (XE) turns ON when all A/D conversion-enabled channels have completed the initial A/D conversion.

[For the Q66AD-DG]

• When the A/D conversion is enabled in the off condition of the external power supply and the initial A/D conversion is completed, the channels for the analog current input range without a 2-wire transmitter are set to 1. Also, the channels for the 2-wire transmitter range remain 0. If the external power supply is turned on and the initial A/D conversion is completed, the channels are set to 1.

• When the external power supply is turned off, the channels for the 2-wire transmitter range only are set to 0. The channels for the analog current input range without a 2-wire transmitter remain 1.

(4) Based on an input signal error detection setting value (input signal error upper and

lower limit setting values), an input signal upper and lower limit values are calculated as shown below.

The calculated values vary depending on the input range.

(a) Input signal error detection upper limit value

= gain value of corresponding range + (gain value of corresponding range offset value of corresponding range) {input signal error detection setting value (Input signal error detection upper limit setting value) /1000}

(b) Input signal error detection lower limit value

= lower limit value of corresponding range + (gain value of corresponding range - offset value of corresponding range) {input signal error detection setting value (Input signal error detection lower limit setting value) /1000}

*1 For the lower limit value, offset value, and gain value for each input range, refer to Point (3) in this

section.

[Example When same upper limit value/lower limit value is selected for the input signal error detection extended setting, setting 15% (150) to the input signal error detection setting value in the Q68AD-G] Resolution mode : High resolution mode Used range : User range setting (Offset value: 5mA, Gain value: 18mA) In this setting, because the lower limit value is an analog value at the time the digital value is -12000, it is -8mA. Therefore, the input signal error detection upper and lower limit values are as follows: Input signal error detection upper limit value = 18 + (18-5) x 150/1000 = 19.95mA Input signal error detection lower limit value = -8 - (18-5) x 150/1000 = -9.95mA
