Execute One

Use the Execute One branch control when the processing of a single leg of a branch is required. The Procedure evaluates the branch beginning with the left-most leg. If the transition logic is True or there is no transition logic, the Capability instances in the branch leg are processed. All other branches are ignored. If all the legs of a branch have transition logic that is False, the procedure continues the evaluation of each transition until one of the legs changes to a state of True.

For an Execute One branch, a transition is automatically added at the top of each leg.

The top and bottom edges of the Execute One branch control are graphically shown as a single horizontal line.
