ChangingEdgeOutput 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.
