Example: AVRG
The following example demonstrates a program that calculates the average values of data register D100 and store the result to
data register D200 every 500 scans.

When the sampling end input does not turn on
While sampling end input I10 is off, the average, maximum, and minimum values are calculated every 500 scans and stored to
data registers D200, D201, and D202, respectively. Sampling completion output M100 is set every 500 scans.

Sampling End Input I10
Sampling Completion Output M100
When the sampling end input turns on
When sampling end input I10 turns on, the average, maximum, and minimum values at this point are stored to data registers
D200, D201, and D202, respectively. Sampling completion output M100 is also set. When sampling end input I10 turns off,
sampling resumes starting at the first scan.

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the source,
16 points (word or integer data) or 32 points (double-word or long data) are used.
When a word device such as T (timer), C (counter), or D (data register) is assigned as the source, 1 point (word
or integer data) or 2 points (double-word, long, or float data) are used.
