Overview > Greater (2 inputs)

Compares the two inputs W1 and W2. If W1 is greater than W2, 1 is output at A1, otherwise 0. The parameters "Hysteresis" and "Type" allow a switching hysteresis to be set, which prevents the output from chattering on small fluctuations around the comparison value.


Inputs

W1
 Value 1
 First comparison value.
W2
 Value 2
 Second comparison value.

Outputs
A1
 Output
 1 if W1 is greater than W2, otherwise 0.

Parameters
Hysteresis
 Switching difference (dead band) around the comparison value. Prevents the output from chattering on small fluctuations. 0 = no hysteresis.
Type
 Defines how the hysteresis acts around the comparison value:
  • Plus/Minus: hysteresis symmetrically above and below the comparison value.
  • Minus only: hysteresis only below the comparison value.
  • Plus only: hysteresis only above the comparison value.
