|
||
|
|
selected for each channel. |
•Q68ADV ........ 8 channels, all of which are voltage input.
•Q68ADI .......... 8 channels, all of which are current input.
(2)High speed conversion
Conversion is performed at a high speed of 80 s/channel. Also, the temperature drift compensation function can be performed using a processing time of "conversion time for all channels + 160 s".
(3) High degree of accuracy
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 can be used to set initial settings and automatic refresh settings on screen, reduce sequence programs, and check settings and operating status.

See the user’s manual for the CPU module being used for general specifications of the A/D converter modules.
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 resolution mode)
16000 (when -10 to 10 V or 0 to 10 V is selected in high resolution mode).

Accuracy is represented with respect to the maximum digital output value. Accuracy does not change and remains within the range listed in the performance specification even if the input characteristic is changed by changing offset/gain settings, input range and resolution mode.
Figure 3.5 shows the range of fluctuation in accuracy when a -10 to 10V range is selected and in normal resolution mode. Accuracy is ± 0.1% (± 4 digits) when the ambient temperature is 25 ± 5°C, ± 0.3% (± 12 digits) when the ambient temperature is 0 to 55 °C with temperature drift compensation, and ± 0.4% (± 16 digits) when the ambient temperature is 0 to 55 °C without temperature drift compensation.

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.

[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.

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)

(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.
