Common plant model for modelling of physical plant items of production plant

Abstract

The invention discloses a common plant model for modelling of physical plant items of a production plant within a manufacturing execution system having an engineering environment and a runtime environment, 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 the node type model, a facet model and a rule model as well as a hierarchy model, d) a graph model representing physical and/or logical connections between the nodes, e) a wiring chart model defining the interaction between interface members of different facets within the same node and/or among different nodes; and wherein each facet comprises 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 which are linked to a specific node.

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 having 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 acquisition, ...

Problems solved by technology

[0009] Therefore, integration between these different levels of products is difficult and error-prone due to the need to keep the different planning models consistent during engineering as well as runtime

Linking a new control function (i.e. the temperature of a device) to a new target destination in a control environment is still a significant investment so far
