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.
