Abstract: The common plant model offers the possibility to create a mechanism that allows an easier linking of plant items from an engineering aspect being independent of the system, such as MES, SCADA, DCS, ERP, the engineer is working with. The common plant model includes: a node type model aggregating different aspects for the modeling of a single physical plant item; a number of nodes; a library model with a project library and a global library; and a wiring chart model defining the interaction between interface members of different facets. Each facet has at least one interface member and the logical link among the interface members is a virtual wire defining a connection used to propagate and align facet parameters linked to a specific node. The wiring chart is usable by different users. The SCADA and DCS systems have access to the distinct modeling of their individual needs.

Abstract: 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.
