Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This block transforms a Real input signal u into a Boolean output signal y:
- When the output was false and the input becomes greater than parameter uHigh, the output switches to true.
- When the output was true and the input becomes less than parameter uLow, the output switches to false.
The start value of the output is defined via parameter pre_y_start (= value of pre(y) at initial time). The default value of this parameter is false.
Parameters (3)
| uLow |
Value: Type: Real Description: If y=true and u<uLow, switch to y=false |
|---|---|
| uHigh |
Value: Type: Real Description: If y=false and u>uHigh, switch to y=true |
| pre_y_start |
Value: false Type: Boolean Description: Value of pre(y) at initial time |
Connectors (2)

u |
Type: RealInput Description: 'input Real' as connector |
