BooleanValue

Show Boolean value from numberPort or from number input field in diagram layer dynamically

Information

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

This block visualizes a Boolean variable in a diagram animation. The Boolean variable to be visualized can be defined in the following ways:

  • If useActivePort = true (which is the default), a Boolean input is present and this input variable is shown.
  • If useActivePort = false no input connector is present. Instead, a Boolean input field is activated in the parameter menu and the Boolean expression from this input menu is shown.

If the Boolean variable is false the block is "grey", otherwise, it is "green". The two versions of the block are shown in the following image (in the right variant, the name of the variable value that is displayed is also shown below the icon):

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