A/D conversion methods

Sampling processing

Sample processing is performed when the averageprocessing is not specified.

a) Average processing

b) Time average processing

c) Count average processing

d) Moving average processing

e) Weighted average processing

Alarm processing Process alarm and change rate alarm processing areavailable.

Detecting the disconnectionof input signal

If an analog input with a range of 1 ~ 5V (4 ~ 20°) isdisconnected, the user program detects it.

Sampling processing

The sampling period (processing time) depends on the number of the channels in use.

Processing time = Maximum of 10ms per module



4. Configuration4.1. Configuration of analog input module

Average processing

This processing executes A/D conversion with specified count/time and to save theaverage of the accumulated sum on memory. Average processing option and time/count

value can be defined through a user program or I/O parameters setting for respective

channels.

This process reduces the influence of abnormal analog input signals such as noise.

Types of average processing

There are four types of average processing: time, count, moving and weighted average.

1. Time average processing

a) Setting range: 16 ~ 4000 (ms)

b) Number of processing= [setting time/10ms][time]

Example: Setting time: 68ms

Number of processing = 68ms / 10ms = 6.86[times] (rounded)

ATTENTION

1. If set value of time average is not specified within 16 ~ 4000, RUN LEDblinks at an interval of 1s. In order to set RUN LED to on state, set thevalue within the range again and then change the PLC CPU from STOPto RUN mode. Ensure to use request flag of error clear (UXY.11.0) to

clear the error during RUN.

2. If any error occurs in set value of time average, the default value is setas 16.

2. Count average processing

a) Setting range: 2 ~ 500 (times)

The average value of input data at designated times is saved as a real input data.

b) Process time = setting count x 10ms

Example: Average processing time is 50

Processing time = 50*10ms => 500ms





ATTENTION

1. If the set value of count average is not specified within 2 ~ 500, RUNLED blinks at an interval of 1s. In order to set RUN LED to ON state, setthe value within the range and then change PLC CPU from STOP toRUN mode. Ensure to use request flag of error clear (UXY.11.0) to clear the error during RUN.

2. If any error occurs in the set value, the default value is set as 2.

3. Moving average processing

a) Setting range: 2 ~ 200(times)

This process outputs the newest average value in every sampling at thedesignated count times. The following figure shows the moving average

processing with four times.

Output 1 = (O1 + O2 + O3 + O4) / 4

Output 2 = (O2 + O3 + O4+ O5) / 4

Output 3 = (O3 + O4 + O5+ O6) / 4





4. Weighted average processing

a) Setting range: 1 ~ 99(%)

F[n] = (1 - α) x A[n] + α x F [n - 1]

F[n]: Current weighted average output

[n]: Current A/D conversion value

F [n-1]: Former weighted average output

α: Weighted average constant (0.01 ~ 0.99)

ATTENTION

If the set value of count average is not specified within 1 ~ 99, RUN LEDblinks at an interval of 1s. In order to set RUN LED to ON status, reset theset value of frequency average within 2 ~ 500 and then convert PLC CPUfrom STOP to RUN. Be sure to use request flag of error clear (UXY.11.0)to clear the error through modification during RUN.

If any error occurs in the set value, the default value is set as 1.

b) Voltage input (for example)

Analog input range: DC -10 ~ 10V, Digital output range: -32000 ~ 32000.

When an analog input changes rapidly from –10V to 10V (-32000 ~ 32000), thefollowing table describes the outputs of weighted average according to the

constant ().

Outputs of Weighted Average

0 scan 1 scan 2 scan 3 scan

Remarks

(1) 0.010 31360 31993 31999

Weighted 1% to former value

(2) 0.50 0 16000 24000


(3) 0.990 -31360 -30726 -30099







(1) Outputs 32000 after about 4 scans


(3) Outputs 32000 after about 1629 scans (16.29s)

c) Current Input (for example)

Analog input range: DC 0 ~ 20mA, Digital output range: -32000 ~ 32000.

When an analog input changes rapidly from 0mA to 10mA (-32000 ~ 16000),

the following table describes the outputs of weighted average according to the

constant ().

Outputs of Weighted Average

0 scan 1 scan 2 scan 3 scan

Remarks

(1) 0.010 15520 15995 15999


(2) 0.50 -8000 4000 10000


(3) 0.990 -31520 -31044 -30574




(3) Outputs 16000 after 1600 scans (16s)

To get a stabilized output against rapid input changes (for example, noise), the weighted

average processing will be helpful.





Alarm processing

Process alarm

When the input value becomes greater than process alarm HH limit value, or less than LL

limit value, the alarm flag turns on and the alarm LED on the front of the module

Change rate alarm

This function enables to sample data cyclically with the period set in the parameter rate

of change alarm period and to compare every two sample data.

The unit used for rate of change H limit and rate of change L limit is percentage per second (%/s).

1. Setting rate of the sampling period: 10 ~ 5000(ms)

If 1000 is set for the period, the input data is sampled and compared every 1second.

2. Setting range of change rate limit: -32768 ~ 32767(-3276.8%/s ~ 3276.7%/s)

3. Calculation of the criterion

The criterion of change rate alarm = High limit or low limit of change rate alarm X0.001 X 64000 X Detection period ÷ 1000

Example for change rate setting 1(rising rate detection)

1. Detection period of Ch. 0: 10(ms)

2. Alarm high (H) limit of Ch. 0: 100(10.0%)

3. Alarm low (L) limit of Ch. 0: 90(9.0%)

4. Alarm high(H) criterion of Ch.0 = 100 X 0.001 X 64000 X 10 ÷ 1000 = 64

5. Alarm low(L) criterion of Ch.0= 90 X 0.001 X 64000 X 10 ÷ 1000 = 57.6 = 57

6. When the deviation value of ([n]th digital value) – ([n-1] th digital value) becomes

greater than 64, high (H) change rate detection flag of Ch.0 (CH0 H) turns on.

7. When the deviation value of ([n] th digital value) – ([n-1] th digital value) becomes

less than 57, low (L) change rate detection flag of Ch.0 (CH0 L) turns on.





Example for change rate setting 2 (falling rate detection)


2. Alarm high (H) limit of Ch. 0: -10(-1.0%)

3. Alarm low (L) limit of Ch. 0: -20(-2.0%)

4. Alarm high(H) criterion of Ch.0 = -10 X 0.001 X 64000 X 100 ÷ 1000 = -64

5. Alarm low(L) criterion of Ch.0 = -20 X 0.001 X 64000 X 100 ÷ 1000 = -128

6. When the deviation value of ([n] th digital value) – ([n-1] th digital value) becomesgreater than -64, high (H) change rate detection flag of Ch.0 (CH0 H) turns on.


less than -128, low (L) change rate detection flag of Ch.0 (CH0 L) turns on.

Example for change rate setting 3 (detection of change rate)


2. Alarm high (H) limit of Ch. 0: 2(0.2%)

3. Alarm low (L) limit of Ch. 0: -2(-0.2%)

4. Alarm high(H) criterion of Ch.0 = 2 X 0.001 X 64000 X 1000 ÷ 1000 = 128

5. Alarm low(L) criterion of Ch.0 = -2 X 0.001 X 64000 X 1000 ÷ 1000 = -128


greater than 128, high (H) change rate detection flag of Ch.0 (CH0 H) turns on.


less than -128, low (L) change rate detection flag of Ch.0 (CH0 L) turns on.
