Chapter 11 Using the PhaseManager Tool
With a state model, you define the behavior of your equipment during Acting
states.
How Equipment Changes States
The arrows of the state model show the states through which your equipment
progresses:
• Each arrow is called a transition.
• A state model lets the equipment make only certain transitions. This
restriction standardizes the behavior of the equipment so that other
equipment using the same model behaves the same way.
