• Processes the value specified at (S3) to a data in the range defined
by the upper and lower limits set at (S1) and (S2), and stores it to the
word device specified at (D).
• Processes the value specified at (S3+1, S3) to a data in the range
defined by the upper and lower limits set at (S1+1, S1) and (S2+1,
S2), and stores it to the word device specified at (D+1, D).
• Taking the area set by (S1) and (S2) as the dead band, if the input
value specified at (S3) is within the dead band, "0" is stored to the
word device specified at (D) and if it is outside the dead band, the
value obtained by subtracting the dead band upper/lower limit value
from the input value is stored to the word device specified at (D).
• Taking the area set by (S1+1, S1) and (S2+1, S2) as the dead band,
if the input value specified at (S3+1, S3) is within the dead band, "0"
is stored to the word device specified at (D) and if it is outside the
dead band, the value obtained by subtracting the dead band upper/
lower limit value from the input value is stored to the word device
specified at (D).
