State machines are commonly used to implement decision making algorithms. State machines are used in applications where distinguishable states exist. A finite state machine (FSM) is based on the idea that a given system has a finite number of states. In Summary States: 5 1.Error 2.Configuration 3.Ready 4.Assigned 5.Locked Transitions: 2 1.GO 2.OUT
