摘要:
A system and method for preparing, using and displaying a state model of a process, as an industrial or business process, as a sequence of discrete steps. The state model defines the behavior of the logical objects making up a process model of the process as a set of permitted states and a set of permitted transitions between the permitted states. The method involves creating a state model (61) with certain parameters, a Create/Modify State Transition for a State Model (63) and Associate State Transition with Rules and Conditions (65). These rules are inputted into a graphical user interface which causes appropriate rules to be extracted from a database (67). They are assembled into a state machine execution engine (69) and implemented (70) to produce an enforced state model on targeted business objects (71) and the target business object is enabled (73).

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.
摘要:
A method of using status images describing a process in a control system for an industrial automation process. In the method, process values are collected from the process describing the status thereof. Structured status documents are generated from the process values collected from the process. The process values comprised by at least two status documents are compared when there is need to find the differences in the operation of the process at different points in time. The differences in the status documents are displayed to a user.
