"311 – W. Comp (2 V)" (Window comparator, two variables)
"312 – W. Comp (2 V)" absolute value" (Window comparator, two variables, absolute value)
− 311 – W. comp (2 V)
Description:
It is checked if I1 is in the adjusted range (window) around I2.
O1 is TRUE if I1 is in the range of I2. The range is set up with P1 (positive window) and P2
(negative window).
O1 is FALSE if I1 is outside of this range.
The comparator has three working ranges:
Range 1
Range 2
Range 3 I1 < (I2 - P2)
− 312 – W. comp (2 V), absolute value
Description:
It is checked if the absolute value I1 is in the adjusted range (window) around absolute value
of I2.
O1 is TRUE if |I1| is in the range of |I2|. The range is set up with P1 (positive window) and P2
(negative window).
O1 is FALSE if |I1| is outside of this range.
The comparator has three working ranges:
Range 1
Range 2
Range 3 |I1| < (|I2| - P2)
The output value can be changed by means of the two Boolean inputs I3 and I4:
Master Set sets output O1 to TRUE.
Master Reset sets output O1 to FALSE. Master Reset has priority over Master Set.
