Program Example 1:
Set/reset M0 by applying software comparator
M1000
DCNT
C235 K100
DHSCS
C235
K100
M0
 When value in C235 varies from 99 to100, DHSCS instruction sets M0 ON. (M1235 = OFF,
C235 counts up)
 When value in C235 varies from 101 to100, DHSCR instruction resets M0. (M1235 = ON,
C235 counts down)

 When C251 counts up and the value in C251 varies from 100 to101, DHSCS instruction
sets M0 ON.
 When C251 counts down and the value in C251 varies from 100 to 99, DHSCR instruction
resets M0.
