Abstract
A method can include checking states of valves of equipment with respect to a workflow specification according to a checking order defined by assigned numbers; responsive to the checking of the states of the valves, identifying individual valves that are not in a corresponding state as indicated by the workflow specification; and generating a sequence for changing the state of each of the individual valves that is not in its corresponding state to its corresponding state.
