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

摘要

A common plant model models physical plant items of a production plant within a manufacturing execution system. The plant model includes a node type model aggregating different aspects for the modeling of a physical plant item involving public interface parameters and automation parameters, a number of nodes, each representing an instance of a node type, and a library model having a project library and a global library. The libraries contain a node type model, a facet model, a rule model and a hierarchy model. A wiring chart model defines the interaction between interface members of different facets of the nodes. A graph model represents physical and/or logical connections between the nodes. The hierarchy model contains hierarchy definitions and each hierarchy definition contains hierarchy levels and a number of hierarchy level constraints. Each node is assigned to a hierarchy definition and to a hierarchy level within the assigned hierarchy definition.

1. A common plant model for modeling physical plant items of a production plant within a manufacturing execution system having an engineering environment and a runtime environment, the common plant model comprising:
a node type model aggregating different aspects for modeling a single physical plant item involving public interface parameters and automation parameters; a number of nodes each representing an instance of a node type; a library model containing libraries including 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 an interaction between interface members of different facets of the nodes; a graph model representing physical and/or logical connections between the nodes; said hierarchy model having a number of hierarchy definitions and each hierarchy definition containing a number of hierarchy levels and a number of hierarchy level constraints; and each of said nodes is assigned to at least one of said hierarchy definitions and to at least one hierarchy level within an assigned hierarchy definition.
