[DESIGN PRECAUTION]

!

DANGER

• Do not write data into the "system area" of the buffer memory of intelligent function modules.
Also, do not use any "prohibited to use" signals as an output signal to an intelligent function
module from the PLC CPU.
Writing data into the "system area" or outputting a signal for "prohibited to use" may cause a
PLC system malfunction.

!

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(3.9inch) or more from each other.

1 OVERVIEW

1 OVERVIEW

This User's Manual describes the specifications, handling and programming methods
for the type Q64A D -GH cha nn el isola t ed high re so lution analog-digital converter
module (hereinafter referred to as the Q64AD-GH) and type Q62AD-DGH channel
isolated high resol ut io n an al og -dig it al conv e rte r modu le (w ith sign al cond it io nin g
function) (hereinafter referred to as the Q62AD-DGH), which are used with the
MELSEC-Q series CPU modules.
The Q62AD-DGH is exclusively used for current input.
In this manual, the Q64AD-GH and Q62AD-DGH are collectively referred to as the A/D
converter modules.

1.1 Features
(1) Channel isolated

The channels are isolated.
The Q62AD-DGH is also isolated between the external supply power and
channels.

(2) High resolution

The resolution is as high as 32-bit signed binary (data part is 16 bits long). (When
the -10V to +10V range is selected)

(3) Power supply to 2-wire tr ansmitter ( Q62AD- D GH only)

Supplying power to the 2-wire transmitter, the Q62AD-DGH 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 shor t-circ uit pr otecti on cir cui t

(Q62AD-DGH 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 (Q62AD-D GH 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.

(6) High accuracy

The reference accuracy 1 is as high as ±0.05% and the temperature coefficient

2

is as high as ±71. 4pp m/°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°C to 30°C

0.05% (reference accuracy) + 0.00714%/°C (temperature
coefficient)

5°C (temperatu re va ri a tio n di ffe re n ce ) = 0. 0 857%

The input range 3 ca n ea sily be set fro m th e GX De vel o pe r.

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 .

(11) Online module change

The module can be changed without the system being stopped.
Further, the dedicated instruction (G. OGLOAD, G. OGSTOR), write to the buffer
memory, or turning ON the Y signal enables "inheritance of offset/gain settings to
the new A/D conve rt er mod ule repl a ci ng th e old one changed online" and
"transfer of offset/gain settings to the other A/D converter module mounted on the
other slot". (These apply to the modules of the same model.)

(12) Offset/gain setting

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

(13) Easy settings using the utility package

A utility package is sold separately (GX Configurator-AD).
The utility package is not a required item, however, it is useful for on-screen
setting of the intelligent function module parameters (initial setting/auto refresh
setting). In addition, FB

can be generated au to matically from the intelligent

function module parameters that have been set up and used in a sequence
program.

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.

For the details of FB, refer to "GX Developer Version 8 Operating Manual

The conversion speed is 10ms regardless of the number of conversion enabled
channels.

(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 minimu m value s is averaged , and the result is stored
into the buffer memory .
The processing co un t wi th in t h e set ti me i s un i form independently of the
number of used channels (numbe r of chann els set for A /D conversion enable).

Processing count = set time/10 (times)
[Example] When the averaging processing time is set to 42ms

42/10 = 4.2 (times) ... Fractional portion is dropped.

(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 when the count-based average value is stored into the buffer
memory is uniform independently of the number of used channels (number
of channels set for A/D conversion enable).

Processing time = set count

10 (ms)

[Example] When the averaging processing count is set to 5 times

5

10 = 50 (ms)

(c) Move averaging

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 digi ta l ou tpu t va l ue is avai la bl e.

channel basis.

(2) To make the setting valid, the Operating condition setting request (Y9) must be

turned ON/OFF. (Refer to Section 3.3.2.)

(3) The setting range is 0 to 250 (0 to 25.0%). Set the value in 0.1% increments.

Example) When setting the input signal error detection setting value to 15%, store

150 into the buffer memory.

(4) The input signal error detection upper and lower limit values depend on the used

range.
The expressions for calculating the input signal error detection upper and lower
limit values are as follows.

Input signal err o r dete ctio n up pe r limit value
= gain value of corresponding range + (gain value of corresponding range - offset

value of corresponding range)

(setting value/1000)

Input signal error detection lower limit value
= lower limit value of correspo nding range

+ (gain value of corresponding range

- offset value of corresponding range)

(setting value/1000)

When the user range setting is used, the lower limit value is as follows.

Example) Lower l i mit value w hen th e ga in value se tt in g i s 8V and th e o ffse t

value setting is 4V
For the user range setting (uni-polar) of the Q64AD-GH or the user
range setting of the Q62AD-DGH, the offset value is the lower limit
value.

Gain value 8V 64000

Offset value

(Lower limit value)

4V 0

For the user range setting (bi-polar), the analog value corresponding
to the digital value of -64000 is the lower limit value.

Gain value 8V 64000

Offset value 4V 0

Lower limit value 0V -64000

4.4 Wiring

The wiring precautions and examples of module connection are provided below.

4.4.1 Wiring precautions

In order to optimize the functions of the A/D converter module and ensure system
reliability, external wiring that is protected from noise is required.
Please observe the following precautions for external wiring:

(1) Use separate cables for the AC control circuit and the external input signals of the

Q64AD-GH to avoid the influence of the AC side surges and inductions.

(2) Use separate cables for the AC control circuit and the external input signals and

external supply power of the Q62AD-DGH to avoid the influence of the AC side
surges and inductions.

(3) Do not mount the cables close to or bundle them with the main circuit line, a high-

voltage cable or a load cable from other than the PLC.
This may increase the effects of noise, surges and induction.

(4) Perform an one-point grounding for shielded lines and the shields of sealed

cables.

(5) A solderless terminal with insulating sleeve cannot be used for the terminal block.

Covering the cable-connection portion of the solderless terminal with a marked
tube or an insulation tube is recommended.

specified in POINT of Section 3.1.2 (1).
When the setting exceed s thi s range, the maximum re sol ution or total accur acy
may not be withi n the range i ndi cat ed in th e pe r forman ce spe ci fi cation .

(2) Though the offset/gain settings can be performed on multiple channels at the

same time, set the offset and gain separately (0 at either of the buffer memory
addresses 22, 23).
If channels are set at the buffer memory addresses 22 (Un\G22) and 23
(Un\G23) at the same time, an error will occur and the ERR. LED will be lit.

4 SETUP AND PROCEDURES BEFORE OPERATION

1 The mode switching (normal mode to offset/gain setting mode to normal mode) method

is given below.

• Dedicated instruction (G.OFFGAN) ............. Refer to Section 4.6.2 (2), (a)

• Setting made to mode switching setting (buffer memory addresses 158, 159:
Un\G158, Un\G159) and turning the operation condition setting request (Y9) from OFF

to ON ............................................................Refer to Section 4.6.2 (2), (b)

• Intelligent function module switch setting ....Refer to Section 4.5, Section 4.6.2 (2), (c)

(After intelligent function module switch setting, reset the PLC CPU or switch power
OFF, then ON.)

2 Turning ON the channel change request (YB) starts power supply from the

corresponding channel to the 2-wire transmitter. After fully checking the wiring, settings,
etc., turn ON the ch an nel ch ang e req ue st (YB) .

POINT

(1) Perform the offset/gain settings in the range that satisfies the conditions

specified in POINT of Section 3.1.2 (2).
When the setting exceed s thi s range, the maximum re sol ution or total accur acy
may not be withi n the range i ndi cat ed in th e pe r forman ce spe ci fi cation .

(2) Though the offset/gain settings can be performed on multiple channels at the

same time, set the offset and gain separately (0 at either of the buffer memory
addresses 22, 23).
If channels are set at the buffer memory addresses 22 (Un\G22) and 23
(Un\G23) at the same time, an error will occur and the ERR. LED will be lit.

(3) After the offset/gain settings are completed, verify that the offset and gain

values have been set correctly under actual usage conditions.

(4) The offset and ga in val ue s ar e sto re d into th e E

2

PROM and are not erased at

power-off.

(5) At the time of offset/gain setting, turn ON the user range write request (YA) to

write the val ue s to the E

2

PROM.

Data can be written to the E

2

PROM up to 100 thousand ti mes.

To prevent accidental write to the E

2

PROM, an error will occur and the error
code (buffer memory address 19: Un\G19) will be stored if write is performed
26 consecutive times.

(6) If an error (error code: 40

1

) occurs during offset/gain setting, re-set the
correct offset/gain value.
The offset/gain value of the channel where the error has occurred is not written
to the A/D converter module. (

1:

indicates the co rr esp on di ng chan nel

number.)

(7) When the offset/gain setting mode is switched to the normal mode, the module

ready (X0) turns from OFF to ON.
Note that the initial setting processing will be executed at this time if there is a
sequence program that performs initial settings when the module ready (X0)
turns ON.

(8) When one mode is switched to the other (the normal mode is switched to the

offset/gain setting mode or the offset/gain setting mode is switched to the
normal mode), A/D conversion is suspended and power supply to the 2-wire
transmitter is turned OFF.
To resume A/D conversion and power supply to the 2-wire transmitter, turn ON
the operating condition setting request (Y9) after the mode is switched to the
normal mode.

(9) Buffer memory addresses 202 to 225 (Un\G202 to Un\G225) are the areas

used to restore the user range settings offset/gain values when online module
change is made.
Refer to chapter 7 for details of online module change.

5.2 Installing and Uninstalling the Utility Package

See "Method of installing the MELSOFT Series" attached with the utility package
regarding the install and uninstall operation for the utility package.

5.2.1 User precautions

The following provides the precautions on using the GX Configurator-AD:

(1) Important safety information

Since GX Configurator-AD is add-in software for GX Developer, read "Safety
Precautions" and the basic operati ng procedu res in GX Developer's ope rating
manual.

(2) About installation

The GX Configurator-AD is an add-in package for GX Developer Version 4 or
later products. Therefore, install GX Configurator-AD in a personal computer in
which GX Developer Version 4 or a later product has been installed.

(3) About display-screen errors while usi ng the i ntelligent function

module utility

There may be cases in which the screen will not properly display while the
intelligent function module utility is being used, due to a lack of system resources.
If this occurs, close the intelligent function module utility first and then GX
Developer (program, comments, etc.) and other applications. Next, restart GX
Developer and the intelligent function module utility.

(4) To start the intelligent function module utility

(a) In GX Developer, select "QCPU (Q mode)" for the PLC series and specify

the project.
If something other than "QC PU (Q mode )" is selected for the PLC seri es, or if
the project is not specified, t he intell igent fun ction module utility will no t start.

(b) Multiple intelligent function module utilities can be started.

However, the [Open parameter]/[Save parameter] intelligent function
module's parameter operations can only be performed by a single intelligent
function module utility. Other intelligent function module utilities can perform
the [Monitor/test] operation only.

(5) How to switch screens when two or more intell ig ent function

module utilities are started

When two or more intelligent function module utility screens cannot be displayed
side by side, use the task bar to change the intelligent function module utility
screen so that it is displayed on top of other screens.

(6) About the number of parameters that can be set i n GX

Configurator-AD

The number of parameters that can be set by the GX Configurator for an
intelligent function module installed in the CPU module and in a remote I/O
station of the MELSECNET/H network system is limited.

Maximum number of parameter settings

Intelligent function module installation object

Initial setting Automatic refresh setting
Q00J/Q00/Q01CPU 512 256
Q02/Q02H/Q06H/Q12H/Q25HCPU 512 256
Q12PH/Q25PHCPU 512 256
MELSECNET/H remote I/O station 512 256

For example, if multiple intelligent function modules are installed in a remote I/O
station, set the GX Configurator so that the number of parameter settings of all
the intelligent function modules does not exceed the maximum number of
parameter settings. The total number of parameter settings is calculated
separately for the initial setting and for the automatic refresh setting.
The number of parameter settings that can be set for one module in the GX
Configurator-AD is as shown below.

Object Module Initial setting Automatic refresh setting
Q64AD-GH 4 (Fixed) 27 (Maximum number of settings)
Q62AD-DGH 8 (Fixed) 15 (Maximum number of settings)

Example) Counting the number of parameter settings in the automatic refresh

setting

The number of settings in this one line is counted
as one setting.
The number of settings is not counted by columns.
Add up all the setting items in this setting screen,
then add them to the total for the other intelligent
function modules to get a grand total.
