COMMON PLANT MODEL FOR MODELING OF PHYSICAL PLANT ITEMS OF A PRODUCTION PLANT

A common plant model for the MES, SCADA and DCS systems of a production facility benefits from an integration architecture that enables a stringent and persistent modeling of the physical resources of a production facility. The common plant model for modeling of physical plant items within a manufacturing execution system having an engineering environment and a runtime environment, contains: a node type model aggregating different aspects for the modeling of a physical plant item containing public interface parameters and automation parameters; a number of nodes, each representing an instance of one distinct node type; a library model containing a project library and a global library, the libraries containing the node type model, a facet model, a rule model and a hierarchy model; a wiring chart model defining the interaction between interface members of different facets of a node; and a graph model representing physical and/or logical connections between the nodes.
