Operation (comparator) < Less than: the “OUT” output is logic “1” as long as the value of the inputs is below the dec-
imal value entered as the constant. The “O
UT” output is set to logic “0” if the value of the in-
puts is above or equal to the decimal value entered as the constant.
>= Greater than or equal to: the “O
UT” output is logic “1” as long as the value of the inputs is
above or equal to the decimal value entered as the constant. The “O
UT” output is set to logic
“0” if the value of the inputs is below the decimal value entered as the constant.
> Greater than: the “OUT” output is logic “1” as long as the value of the inputs is above the
decimal value entered as the constant. The “O
UT” output is set to logic “0” if the value of the
inputs is below or equal to the decimal value entered as the constant.
<= Less than or equal to: the “OUT” output is logic “1” as long as the value of the inputs is
below or equal to the decimal value entered as the constant. The “O
UT” output is set to logic
“0” if the value of the inputs is above the decimal value entered as the constant.
= Equal to: the “O
UT” output is logic “1” as long as the value of the inputs is equal to the dec-
imal value entered as the constant. The “O
UT” output is set to logic “0” if the value of the in-
puts is not equal to the decimal value entered as the constant.
!= Not equal to: the “O
UT” output is logic “1” as long as the value of the inputs is not equal to
the decimal value entered as the constant. The “O
UT” output is set to logic “0” if the value of
the inputs is equal to the decimal value entered as the constant.

Figure 5-101 “DIGITAL COMPARATOR” (Signals comparator)
When this parameter is selected, the DIGITAL COMPARATOR operator performs a com-
parison between the first four inputs A (“In1_A” ... “In4_A”) and the second four inputs B
(“In1_B” ... “In4_B”).
