How Equipment Changes States
The arrows in the state model show how your equipment can transition from one
state to another.
• Each arrow is called a transition.
• A state model lets the equipment make only certain transitions. This
transition restriction standardizes equipment behavior so that another
piece of equipment using the same model will behave the same way.

Fault (specific use of the abort command)
Your equipment can go from any state in the box
to the stopping or aborting state.

Description
Command A command tells the equipment to start doing something or do something different. For example the operator pushes the start button to start production and the
stop button to halt production.
PhaseManager uses these commands:
• Reset
• Start
• Stop
• Hold
• Restart
• Abort
Done Equipment goes to a waiting state when it has completed a task. You don’t have to command equipment to stop. Instead, set up your code to signal when a task is
complete.
Fault A fault tells you that something unusual has occurred. Set up your code to find and take action for faults. Suppose you want your equipment to shut down as fast
as possible in case of a certain fault. In that case, set up your code to look for that fault and give the abort command if it finds it.
