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.
