WOLFRAM SYSTEM MODELER

ChangingEdge

Output y is true, if the input u has either a rising or a falling edge and otherwise it is false (y=change(u))

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

A changing edge, i.e., either rising or falling, of the Boolean input u results in y = true at this time instant. At all other time instants, y = false.

The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.BooleanNetwork1.

Parameters (1)

pre_u_start

Value: false

Type: Boolean

Description: Value of pre(u) at initial time

Connectors (2)

u

Type: BooleanInput

Description: Boolean input signal
y

Type: BooleanOutput

Description: Boolean output signal

Used in Examples (1)

BooleanNetwork1

Modelica.Blocks.Examples

Demonstrates the usage of blocks from Modelica.Blocks.MathBoolean

Used in Components (1)

ClockToBoolean

Modelica.Clocked.BooleanSignals.NonPeriodic

Block to translate clock signals to continuous Boolean events (each time the input clock ticks a rising Boolean output edge is produced).
