The degree of accuracy for the conversion process is ± 0.1% (When the ambient temperature is 25 ± 5 °C).

(4) Changing the resolution mode

The resolution mode can be changed according to the application, and digitalvalue resolution settings of 1/4000, 1/12000 or 1/16000 can be selected.

(5) Changing the input range

The input range 1 can easily be set from the GX Developer.

1: 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.

(6) 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

1

can be generated automatically 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

(Function Block)."

3.2 Function List

Table 3.2 shows the function list of the A/D converter modules.

Table 3.2 Function list

A/D conversion enable/ disable setting

A/D conversion method

(1) Specifies whether to enable or disable the A/D conversion for each channel.

(2) By disabling the conversion for the channels that are not used, the sampling time can be shortened.

(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.

Maximum and minimum values hold function

(1) The maximum and minimum values of the digital output values is retained in the module.

Temperature drift compensation function

Resolution mode

(1) Errors arising from changes in the ambient temperature of the module are automatically compensated for to improve conversion accuracy.

(2) The temperature drift compensation function can be performed at (A/D conversion time for all channels) + 160 s.

(1) The resolution mode can be switched according to the application, and digitalvalue resolution settings of 1/4000, 1/12000 or 1/16000 can be selected.

(2) The resolution mode setting is applicable to all channels.

(3) See Section 3.1.1 for the digital output values and maximum resolution in normal resolution mode and high resolution mode.

Online module change (1) A module change is made without the system being stopped.

——

Section 3.1.1

Section 4.5

Chapter 7

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 channels (channels 1, 2 and 4) are A/D conversion enabled with the temperature drift compensation function, the sampling processing time is 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.

MELSEC-Q

(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.

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 is output every 48 ms.

100 {(4 80) + 160} ÷ 1000 = 48 (ms)

3.2.2 Maximum and minimum values hold function

(1) The maximum and minimum digital output values for each channel are stored in buffer memory addresses 30 to 45 (Un\G30 to Un\G45).

(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 of time can be checked.

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 highvoltage cable or a load cable from other than the programmable controller. 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.

MELSEC-Q

1 The mode switching (normal mode to offset/gain setting mode to normal mode) method is given below.

• Dedicated instruction (G(P).OFFGAN) ........ Refer to Section 4.6 (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), (b)

• Intelligent function module switch setting ..... Refer to Section 4.5, Section 4.6 (2), (c)

(After intelligent function module switch setting, reset the programmable controller

CPU or switch power OFF, then ON.)

POINT

(1) Perform the offset/gain settings in the range that satisfies the conditions specified in Section 3.1.2, (1) and (2).

When the setting exceeds this range, the maximum resolution or total accuracy may not be within the range indicated in the performance specification.

(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 in buffer memory addresses 22

(Un\G22) and 23 (Un\G23) at the same time, an error will occur and the

ERROR 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 gain values are stored into the 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 values to the E

2

PROM.

Data can be written to the E

2

PROM up to 100 thousand times.

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 corresponding channel number.)

(7) Module Ready (X0) turns from OFF to ON when the offset/gain setting mode switches to the normal mode by the dedicated instruction (G(P).OFFGAN) or the setting of the mode switching setting (buffer memory addresses 158, 159:

Un\G158, Un\G159).

Note that initial setting processing will be executed if there is a sequence program that makes initial setting when Module Ready (X0) turns ON.

(8) Buffer memory addresses 200 (Un\G200), 202 to 233 (Un\G202 to Un\G233) are the areas used to restore the user range settings offset/gain values when online module change is made.

POINT

The dedicated instructions used for reading/writing the buffer memory of the intelligent function module on a remote I/O station (REMTO and REMFR) are the execution type for which several scans are needed. Therefore, transmissions of the execution results are not synchronized with the I/O signal operations. When reading a digital output value on an A/D converter module after changing the operating condition during operation, be sure to read the A/D conversion completed flag (buffer memory address 10) at the same time.

Also, for the case of changing the operating condition, insert an interlock to prevent the execution of the REMFR instruction.

7 ONLINE MODULE CHANGE

7


When changing a module online, carefully read the QCPU User's Manual (Hardware

Design, Maintenance and Inspection),section 12.4.1 "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 buffer memory.

POINT

(1) Perform an online module change after making sure that the system outside the programmable controller will not malfunction.

(2) To prevent an electric shock and malfunction of operating modules, provide means such as switches for powering off each of the external power supply and external devices connected to the module to be replaced online.

(3) 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).

(4) It is recommended to perform an online module change in the actual system in advance to ensure that it would not affect the other modules by checking the following:

• Means of cutting off the connection to external devices and its configuration are correct.

• Switching ON/OFF does not bring any undesirable effect.

(5) Do not install/remove the module to/from the base unit, or the terminal block to/from the module more than 50 times after the first use of the product. (IEC

61131-2 compliant)

Failure to do so may cause malfunction.

(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.

: If the module is mounted on the remote I/O station, execute save/restoration in the other system mounted on the main base unit. (Save/restoration cannot be executed in the other system mounted on the remote I/O station.)

(1) Functions

(a) Restores the offset/gain values of the user range setting stored in the CPU to the A/D converter module.

Sequence program

(b) There are two types of interlock signals for the G(P).OGSTOR instruction: the completion device (D) and the status display device at completion (D) +

1.

1) Completion device

Turns ON in the END processing of the scan where the G(P).OGSTOR instruction is completed, and turns OFF in the next END processing.

2) Status display device at completion

Turns ON and OFF depending on the completion status of the

G(P).OGSTOR instruction.

Normal completion : Stays OFF and does not change.

Abnormal completion: Turns ON in the END processing of the scan where the G(P).OGSTOR instruction is completed, and turns OFF in the next END processing.

(c) When the offset/gain values are restored, the reference accuracy falls to about less than three times of the accuracy before that.

(2) Operation error

In any of the following cases, an error occurs and the corresponding error code is stored into the completion status area (S)+1.
