"The StateMachine package defines a set of concepts that can be used for modeling discrete behavior through finite state transition systems. The state machine represents behavior as the state history of an object in terms of its transitions and states. The activities that are invoked during the transition, entry, and exit of the states are specified along with the associated event and guard conditions. Activities that are invoked while in the state are specified as “do Activities,” and can be either continuous or discrete. A composite state has nested states that can be sequential or concurrent.
The UML concept of protocol state machines is excluded from SysML to reduce the complexity of the language.
The standard UML state machine concept (called behavior state machines in UML) are thought to be sufficient for expressing protocols." [omg.org/ spec/ SysML/ 1.3/ PDF]
The example "State machine diagram" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the SysML solution from the Software Development area of ConceptDraw Solution Park.

The vector stencils library "Bank UML state machine diagram" contains 21 shapes for drawing UML state machine diagrams.
Use it for object-oriented modeling of your bank information system.
"The state diagram in the Unified Modeling Language is essentially a Harel statechart with standardized notation, which can describe many systems, from computer programs to business processes. In UML 2 the name has been changed to State Machine Diagram. The following are the basic notational elements that can be used to make up a diagram:
* Filled circle, pointing to the initial state.
* Hollow circle containing a smaller filled circle, indicating the final state (if any).
* Rounded rectangle, denoting a state. Top of the rectangle contains a name of the state. Can contain a horizontal line in the middle, below which the activities that are done in that state are indicated.
* Arrow, denoting transition. The name of the event (if any) causing this transition labels the arrow body. A guard expression may be added before a "/ " and enclosed in square-brackets ( eventName[guardExpression] ), denoting that this expression must be true for the transition to take place. If an action is performed during this transition, it is added to the label following a "/ " ( eventName[guardExpression]/ action ).
* Thick horizontal line with either x>1 lines entering and 1 line leaving or 1 line entering and x>1 lines leaving. These denote join/ fork, respectively." [State machine diagram. Wikipedia]
