Chapter 1 Introduction
State Model Overview A state model divides the operating cycle of your equipment into a series of
states. Each state is an instant in the operation of the equipment. It's the
actions or conditions of the equipment at a given time.
In a state model, you define what your equipment does under different
conditions, such as run, hold, stop, and so forth. You don’t need to use all the
states for your equipment. Use only the states that you want.
There are two types of states.
PhaseManager software uses the following states.
Type of State Description
Acting Does something or several things for a certain time or until
certain conditions are met. An acting state runs one time or
repeatedly.
Waiting Shows that certain conditions are met and the equipment is
waiting for the signal to go to the next state.
