DIGITAL COMPARATOR (UG 6911.12/080)
The Operator DIGITAL COMPARATOR allows to
compare (in binary format) a group of signals with a
constant or two groups of signals to each other.
Comparison with constant:
In this case the Signal Comparator check must not
be activated.
The DIGITAL COMPARATOR block allows to
compare a series of input signals (from 2 to a
maximum of 8) with a integer constant that can vary
from 0 to 255.
Input In1 is the LSB (least significant bit) while input In8 (or less if the number of inputs selected is less than 8)
is the MSB (most significant bit).
Example of operator with 8 inputs
In1 0
In2 1
In3 1
In4 0
In5 1
In6 0
In7 0
In8 1
Decimal value equal to 150
Example of operator with 5 inputs
In1 0
In2 1
In3 0
In4 1
In5 1
Decimal value equal to 26
Among the various operations that can be used are:
• < Lower:
The OUT output will be 1 (TRUE) as long as the input value is less than the decimal value set as constant.
The OUT output will be set to 0 (FALSE) when the input value is higher than or equal to the decimal value set
as constant.
•
≥
Higher or equal:
The OUT output will be 1 (TRUE) as long as the input value is higher than or equal to the decimal value set
as constant. The OUT output will be set to 0 (FALSE) when the input value is lower than the decimal value
set as constant.
• > Higher:
The OUT output will be 1 (TRUE) as long as the input value is higher than the decimal value set as constant.
The OUT output will be set to 0 (FALSE) when the input value is lower than or equal to the decimal value set
as constant.
• ≤
Lower oder Equal:
The OUT output will be 1 (TRUE) as long as the input value is lower than or equal to the decimal value set as
constant. The OUT output will be set to 0 (FALSE) when the input value is higher than the decimal value set
as constant.
• = Equal:
The OUT output will be 1 (TRUE) as long as the input value is equal to the decimal value set as constant.
The OUT output will be set to 0 (FALSE) when the input value is different from the decimal value set as
constant.
• != Different:
The OUT output will be 1 (TRUE) as long as the input value is different from the decimal value set as
constant. The OUT output will be set to 0 (FALSE) when the input value is equal to the decimal value set as
constant.
