Drawing a State Machine Bubble Diagram
A state machine bubble diagram defines one or more states and transitions for
the State Machine functional block. States are shown as bubbles on the
diagram, and transitions are shown as arrows between the states.
You will configure one of the states as the initial state. This state is the first
state selected by the State Machine functional block the first time a state
machine is executed.
States do not generate outputs, they instead define a set of exit conditions to be
monitored by the State Machine functional block. When an exit condition from
the current state becomes true, the State Machine functional block changes to
the next state defined for the transition associated with the exit condition, and
starts to evaluate the exit conditions for the new state. The selected transition
determines the outputs from the State Machine functional block.
For example, you may have one transition between stOff and stOccupied that
occurs when the system is enabled and the outdoor air temperature is hotter
than the indoor air temperature. This transition may put the system into
cooling mode. A second transition between stOff and stOccupied may occur
