Comparison of two variables
Description:
This function compares inputs I1 and I2.
O1 is TRUE if I1 > I2.
O1 is FALSE if I1 < I2.
If a hysteresis (P1 and P2) is set up:
O1 is TRUE if I1 > (I2 + P1).
O1 is FALSE if I1 < (I2 - P2).
The comparator has three working ranges:
Range 1
Range 2
Range 3
Description:
This function compares the absolute values of inputs I1 and I2.
O1 is TRUE if |I1| > |I2|.
O1 is FALSE if |I1| < |I2|.
If a hysteresis (P1 and P2) is set up:
O1 is TRUE if |I1| > (|I2| + P1).
O1 is FALSE if |I1| < (|I2| - P2).
The comparator has three working ranges:
Range 1
Range 2
Range 3
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.
