StateChart outputs are assigned values with UMLActions. UMLActions are defined in conjunction with States (Entry, Do and Exit actions), or Transitions.

A default expression is assigned to each StateChart output. This expression specifies the value of the output if no action is enabled by the stateChart.

There are four fields:

1.	Name:	The name of the input pad.
2.	Width:	Select a named constant that specifies the width in bits of a vector, or Unused if it is one bit.
3.	Visibility:	+ for global, - for local, * for input pad.
4.	Default:	The expression that is assigned to the output when no action is active. The expression is specified with the Expression Editor which opens when you click the button in Out Link field.
