Embodiment Construction

[0055] In the following, the object model of the Common Plant Model (hereinafter referred to as CPM) is described from an implementation-independent perspective. The general idea for the creation and application of the CPM is to employ a single software platform for the control and execution of the production process, where unique tasks are assigned to MES, SCADA and DCS+ systems. Customized software platforms are also referred to as projects in the following.

[0056] CPM is designed to model and organize every related item in a physical manufacturing plant. Physical plant items can represent fixed equipment, movable equipment, tools, assets, and so on. This specification uses the term "CPM node" for a physical plant item. The purpose of the CPM node is to aggregate different aspects for modeling a single plant entity element. This aggregation involves public interface parameters as well as automation parameters. All CPM nodes are characterized by a set of common paramet...

Abstract

The invention discloses a common plant model for modelling of physical plant items of a production plant, comprising: a) a node type model aggregating different aspects for the modelling of a single physical plant item involving public interface parameters as well as automation parameters; b) a number of nodes, each representing an instance of a node type; c) a library model comprising a project library and a global library, said libraries comprising a node type model, a facet model and a rule model as well as a hierarchy model, d) a wiring chart model defining the interaction between interface members of different facets of the nodes; e) a graph model representing physical and / or logical connections between the nodes, wherein f) the hierarchy model comprises a number of hierarchy definitions; g) each hierarchy definition comprises a number of hierarchy levels and optionally a number of hierarchy level constraints among those hierarchy levels; and h) each node is assigned to at least one of said hierarchy definitions and to at least one hierarchy level within the assigned hierarchy definition.

Description

technical field [0001] The present invention relates to a generic plant model for modeling physical plant items of a production plant within a manufacturing execution system comprising an engineering environment and a runtime environment. Background technique [0002] It is well known that methods for manufacturing processes planned by enterprise resource planning (ERP) and produced by the shop floor provide a manufacturing execution system (MES) for modeling, planning, scheduling and executing manufacturing processes and controlling the factory floor level corresponding production steps. In the automation pyramid consisting of levels 0 to 4, the ERP system resides at the highest level at level 4, which represents the corporate level responsible for rough production planning and purchase order processing. The MES system is at level 3, which represents the factory control level, including detailed production modeling, planning, production execution, production data acquisiti...
