Abstract
A composite object group (COG) data structure embodied in a computer-readable medium for building a control system that has both a clock cycle and event processing is provided. An interface for passing information to and from the COG data structure is provided. One or more data flow objects are provided in the COG to accept input data and to produce output data on the clock cycle. The data flow object is connected to the interface and provides sampled-data processing for the control system. One or more state machine objects are provided in the COG; each includes a plurality of states and a plurality of transitions between the states that are each triggered by an event. The state machine object provides event-driven processing for the control system, whereby the COG data structure provides both sampled-data and event-driven processing for the control system.
