3.1.2 I/O conversion characteristic

The I/O conversion characteristic represents the angle formed by a straight line
connecting the "offset value" and "gain value" when the analog signals (voltage or
current input) from outside the PLC are converted to digital values.

Offset value

The offset value denotes the analog input value (voltage or current) that makes the
digital output value 0.

Gain value

The gain value denotes the analog input value (voltage or current) that makes the
digital output value:
4000 (in normal resolution mode)
12000 (when 0 to 5 V, 1 to 5 V, 4 to 20 mA, 0 to 20 mA or the user range setting is

selected in high resol u tio n mode)

16000 (when -10 to 10 V or 0 to 10 V is selected in high resolution mode).

Section 3.4.2

A/D conversion method

(1) Sampling processing

The A/D conversion for analog input values is performed successively for
each channel, and the digital output value is output upon each conversion.

(2) Averaging processing

For each channel, A/D conversion values are averaged for the set number of
times or set amount of time, and the average value is output as a digital value.

3.2.1 A/D conversion methods

There are two A/D conversion methods, sampling processing and averaging processing.

(1) Sampling processing

A/D conversion is performed successively for the analog input value, and the
converted digital output values are stored in the buffer memory.
The sampling processing time depends on the number of channels used (the
number of channels set to A/D conversion enable) and whether the temperature
drift compensation function is available.

(a) Without the temperature drift compensation function

(Processing time) = (Number of channels used )

80 ( s/1 channel)

(b) With the temperature drift compensation function

(Processing time) = (Number of channels used)

80 ( s/1 channel) + 160 s
[Example]
When three channel s ( chann els 1 , 2 a nd 4 ) a re A /D conv er sion e nabled with the
temperature drift co mpensati on func tion, the sa mpling p rocessi ng time i s 400

s.

3

80 + 160 = 400 ( s)

(2) Averaging processing

For channels for which averaging processing is specified, A/D conversion is
performed for the set number of times or the set amount of time. The average
value is calculated from the sum of values excluding the maximum and minimum
values, and then stored in the buffer memory.

3 - 11 3 - 11

MELSEC-Q

3 SPECIFICATIONS

(a) When averaging processing is specified for the set amount of time

1) The number of processing repetitions within the set time differs
according to the number of channels used (number of channels for
which A/D conversion is enabled) and whether or not temperature-drift
compensation is used.

• Without the temperature drift compensation function

(Set time) 1000

(Number of
processing repetitions)

(Number of channels used) 80 ( s/1 channel)

• With the temperature drift compensation function

(Set time) 1000

(Number of
processing repetitions)

=

(Number of channels used)

80 ( s/1 channel) + 160

[Example]
When averaging processing is performed with four channels (channels 1, 2,
3, and 4) for the set time of 50 ms with the temperature drift compensation
function on, measurement is performed 104 times and the average value is
output.

50 1000

(4

80) + 160

= 104.17 (times)

……

Round down the number.

2) When 7 or 8 channels are used with the temperature drift compensation
function on, set the average time to 3 ms or more.
If the time is set to 2 ms or less, the average number of times becomes
less than 3 and it causes the digital output value to become 0 since a
sum excluding the maximum and minimum values will be averaged.

(b) When the averaging processing is specified for the set number of times

The time required to store the average value calculated using the average
number of times in the buffer memory differs according to the number of
channels used (the number of channels set to A/D conversion enable) and
whether or not the temperature drift compensation is used.

1) Without the temperature drift compensation function
(Processing time) = (Set number of times)

{(Number of channels used) 80}/1000

(Unit: ms)

2) With the temperature drift compensation function
(Processing time) = (Set number of times)

[{(Number of channels used) 80} + 160]/1000

(Unit: ms)
[Example]
When averaging processing is performed with four channels (1, 2, 3 and 4)
for the set number of 100 times with temperature-drift compensation on, an
average value i s ou tp ut eve ry 48 ms.

(2) When the operating condition setting completed flag (X09) turns OFF, the values

are cleared to 0 and new maximum and minimum values are stored when
conversion begins.

(3) Since the area for storing the maximum and minimum values can be rewritten with

the sequence program, the maximum and minimum values within a specific period

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/Q68ADV(I) to avoid the influence of the AC side surges and inductions.

(2) 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.

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

cables.

(4) 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.

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 file]/[Save file] 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 2 (Fixed) 13 (Maximum number of settings)
Q68ADV/ADI 2 (Fixed) 25 (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.

7 ONLINE MODULE CHANGE

7 ONLINE MODULE CHANGE

This chapter describes the specifications of an online module change.
(1) Perform an online module change by operating GX Developer.

(2) To ensure ease of offset/gain re-setting, there is a user range save/restoration

function that is performed by executing the dedicated instruction or read/write
from/to bu ffe r me mory.

POINT

• Perform an online module change after making sure that the system outside the
PLC will not malfunction.

• To prevent an electric shock or like, always switch OFF the external power of the
module that will be changed online.

• After the module has failed, data may not be saved properly. Referring to Section

3.4.15, therefore, prerecord the data to be saved (offset/gain values of the
industrial shipment settings and user range settings in the buffer memory).

(Note)
The dedicated instruction cannot be executed during an online module change. When
using the dedicated instruction to execute save/restoration, therefore, execute
save/restoration in the other system.
If the other system is unavailable, execute restoration by performing write to the buffer
memory.

7.1 Online Module Change Conditions

The CPU, A/D conve rte r modu le , GX Develo pe r and ba se un it give n be low are needed
to perform an online module change.

(1) CPU

The Q12PHCPU or Q25PHCPU is needed. Note that it cannot be used on the
remote I/O station of the MELSECNET/H.
For precautions for multiple PLC system configuration, refer to the Process CPU
User's Manual (Function Explanation/Program Fundamentals).

(2) A/D converter module

The module of function version C or later is necessary.

(3) GX Developer

GX Developer of Ver sion 7.10 L o r lat e r is nece ssa ry .

(4) Base unit

1) For an online module change, use the main base unit and Q6 B extension
base unit.
The module installed on the main base unit or Q6

B extension base unit can

be change onli ne .

2) The module instal le d on th e Q5

B extension base unit cannot be changed
online.
When the Q5

B is in use, the module installed on the main base unit cannot

be changed onlin e , ei th er .
