Timeout Expression Tab

Simple states, composite states, concurrent states, and regions within a concurrent state, can each have a timeout, timeout expression and timeout action.

The Timeout Expression tab has a declaration section which references the owner concept. You cannot add anything to the declaration.

In the Timeout Expression tab Actions section, you define the length of the timeout by entering an expression that evaluates to a number (that is, a number of the time units you chose in the Timeout tab).
