How Equipment Changes States
The state model’s arrows 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 equipment’s behavior so that
other equipment using the same model will behave the same
way.
PhaseManager Transition Commands
Type of Transition Description
Command A command tells the equipment to do something. For example, the operator pushes the start button to
begin production and the stop button to halt production.
PhaseManager uses these commands:
Reset Stop Restart
Start Hold Abort
Done Equipment goes to a waiting state when it is finished with what it is doing. You do not give the
equipment a command. Instead, you set up your code to signal when the equipment is finished.
Fault A fault tells you that something out of the ordinary has happened. You set up your code to look for
faults and take action if it finds any. If you want to shut down your equipment as quickly as possible
when it detects a fault, set up your code to look for that fault and give the abort command if it finds it.
