Configure PhaseManager Application Chapter 8
In a state model, you define what your equipment does under different
conditions, such as run, hold, and stop. You don’t need to use all the states for
your equipment. Use only needed states.
Figure 23 - PhaseManager States
With a state model, you define the behavior of your equipment and put it into a
brief functional specification. In this way you show what happens and when it
happens.
