Refinement of Statemachines
This example of an ATM (automated teller machine) shows the techniques used to make a refinement of a state machine. The example uses a machine-level state machine (i.e. not in a class). The state machines use the state-sets translation which, since there are no class instances, results in each state being represented by a boolean variable.
create a machine called ATM_A, open its class diagram and then add a statemachine called atm_sm to the canvas. Open the state machine and draw the state machine shown in the diagram below.
