You can insert Steps into your SFCs with the [Step] tool.
Select the [Step] tool from the toolbar, click anywhere on the
screen, and place the Step into the application work area as
needed.
Simultaneous Transition
Transitions determine when the process flow passes from a
preceding Step to the successive Step along the directed link.
Simultaneous Transitions are represented by a horizontal line
across the vertical directed link. Each Transition has an
associated Transition condition, a single Boolean expression.
Transition names are local to the program in which the
Transition is located.
