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

(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.
(1) The maximum and minimum values of the digital out put values is retained
in the module.
(1) Errors arising from changes in the ambient temperature of the module are
automatically compensated for to improve conversion acc uracy .
(2) The temperature drift compensation function can be performed at (A/D
conversion time for all channels) + 160
(1) The resolution mode can be switched according to the application, and digital-
value resolution settings of 1/4000, 1/12000 or 1/16000 can be selected.
(2) The resolution mode setting is applicable to all channel s.

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 u sed)
(b) With the temperature drift compensation function
(Processing time) = (Number of channels used)
[Example]
When three channels (channels 1, 2 and 4) are A/D conve r sion e nabl ed w i th th e
temperature drift co mpensati on fun ction, the sampling p rocessi ng time i s 400
(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.

(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
(Number of
processing repetitions)
=
(Number of channels used) 80 ( s/1 channel)
• With the temperature drift compensation function

[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.

……
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 is ou tp ut eve ry 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.
