Overview >= Greater or equal (1 input)

Compares input W1 with the comparison value set in the parameter "Value 2". If W1 is greater than or equal to "Value 2", 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
 Comparison value. Compared with the parameter "Value 2".

Outputs
A1
 Output
 1 if W1 is greater than or equal to "Value 2", 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.
Value 2
 Comparison value (constant) the input W1 is compared with.
