An object-oriented development system for developing control schemes for facilities includes a device diagramming component for describing a physical description of a facility and a logical definition of a control scheme for the facility. The device diagramming component includes a mode for selecting device symbols representative of equipment or control functions used in facilities. The device symbols are selected from an object-oriented repository containing a plurality of device symbols and device objects. Certain types ofdevice symbols relate to device objects containing logical instructions and configuration information relating to the represented equipment or control functions. The device diagramming component also includes a mode for interrelating in a graphical manner the selected device symbols and their corresponding device objects into a device diagram representing the physical description of the facility and the logical definition of the control scheme for the facility. A device logic developing component defines the logical instructions of the device objects relating to the equipment or control functions. Thus, the development system integrates in a graphical format the physical description of the facility with the logical instructions which define the control scheme for the facility. These logical instructions unify the configuration of analog/regulatory control with the configuration of discrete/sequential/interlocking control.

[ Having described the invention, we claim:] [1.] An object-oriented development system for developing control schemes for facilities, the development system utilizing a graphical user interface environment, the system comprising:device diagramming means for describing a physical description of a facility and a logical definition of a control scheme for the facility, the device diagramming means including,means for selecting device symbols representative of equipment or control functions used in facilities, the device symbols being selected from an object-oriented repository containing a plurality of device symbols and device objects, and wherein certain types of device symbols relate to device objects containing logical instructions and configuration information relating to the represented equipment or control functions, andmeans for interrelating in a graphical manner the selected device symbols and their corresponding device objects into one or more device diagrams, each of the device diagrams representing both the physical description of the facility or a portion of the facility and the logical definition of the control scheme for the facility or the portion of the facility; anddevice logic developing means for defining the logical instructions of the device objects relating to the equipment or control functions;wherein the development system integrates in a graphical format the physical description of the facility with the logical instructions which define the control scheme for the facility, and wherein the logical instructions unify configuration of analog/regulatory control with configuration of discrete/sequential/interlocking control.
