Description:
This function compares inputs I1 and I2. This function is intended for long variables (positions,
ramps of table positioning).
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).
O1 remains unchanged if I1 is in the range of the hysteresis: (I2 - P2) < I1 < (I2 + P1).
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:
− Master Set sets output O1 to TRUE.
− Master Reset sets output O1 to FALSE. Master Reset has priority over Master Set.
