摘要:
The proposed common plant model shall offer the possibility to create a mechanism that allows an easier linking of plant items from an engineering aspect being independent from the system (MES, SCADA, DCS, ERP) the engineer is working with. This objective is achieved by 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. The wiring chart can be used by a plurality of different users that are in a business relation to the physical plant items. In particular, the SCADA system and the DCS system have now access to the distinct modelling of their individual needs in terms of the connections within the same physical plant item and/or among different physical plant items within the environment of the MES.

This common plant model therefore provides a standardized architecture for the modelling of the hierarchies for the physical plant items which can be used by a plurality of different user that are in a business relation to the physical plant items. In particular, the SCADA system and the DCS system have now access to the distinct modelling of their individual hierarchical needs within the environment of the MES which is with respect to the execution and the control of the production of the plant the predominant system.

It is the aim of the present invention to provide a method and a system for managing data of a database in a MES system, whereby enabling a better horizontal scalability of the client-server applications. This aim is achieved by a method and a system for managing the data in a manufacturing execution system, wherein said manufacturing execution system manages and control the planning and the execution of a production process of a product, comprising the steps of: a) providing a number of resources and/or clients (C), such as machines, working personal, users, production line managers, applications, libraries, that are involved to execute the production process thereby generating and/or requesting data related to the production process, b) providing a relational database system that stores the data related to the production process, said relational database system comprising a separate write database (Write_DB) and a separate read database (Read_DB); c) providing a central service bus (CB) which links the number of resources to the write database (Write_DB); d) providing a logical worker entity (W) being enabled to handle commands from the resources and/or clients queued in the central service bus (CB) thereby interpreting the actions related to the write database (Write_DB), collecting the data required to complete the actions and launching the execution of the command; and e) providing a logical reader entity (R) being enabled to capture all data requests from the resources and/or clients thereby launching the requests to get data from the read database (Read_DB) and sending this data back to the resource and/or clients requesting that data.
