expansion unit 3-16
AD CH4＝0，AD mode is disabled.
For example: DA mode D8278＝H3210
DA CH5＝0，DA mode is disabled；
DA CH6＝1，0~10V Voltage output mode (0~4000)；
DA CH7＝2，0~20m ACurrent output mode (0~2000)；
DA CH8＝3，4~20mA Current output mode or 1~5V Voltage output mode (0~2000).
Software filter for analog input expansion unit
(Mode 1): refresh data in each scan time.
Sampling the latest 5 AD data, then eliminate the max and min data, finally get the
average of the remained 3 data.
(Mode 2): refresh data in every 5 scan times.
Sampling the 5 consecutive data from mode 1, then get the average of the 5 data.
(Mode 3): refresh data in every 25 scan times.
Sampling the 5 consecutive data from mode 2, then get the average of the max and
min data.
For example: sampling data
1
=161, sampling data
2
=120，sampling data
3
=154, sampling data
4
=160,
sampling data
5
=190, sampling data
6
=169, sampling data
7
=110, sampling data
8
=121, sampling
data
9
=150, sampling data
10
=198, sampling data
11
=199.
 Mode 1:
① Refreshed data = (161+154+160)/3=158— filter (1, 2, 3, 4, 5)
Eliminate max 190 and min 120.
② Refreshed data= (154+160+169)/3=161—Filter (2, 3, 4, 5, 6)
Eliminate max 190 and min 120.
③ Refreshed data= (154+160+169)/3=161—Filter (3, 4, 5, 6, 7)
Eliminate max 190 and min 110.

:
 Refreshed data= (121+150+198)/3=156—Filter (7, 8, 9, 10, 11)
Eliminate max 199 and min 110.
 Mode 2：
Get the average of the 5 data from mode 1.
(++++)/5
 Mode 3：
Get the average of the max and min data among 5 consecutive data from mode 2.
This mode can efficiently filter the ripple noise.
