System for maintaining unified access to SCADA and manufacturing execution system (MES) information

摘要

A system is disclosed that simplifies configuring an MES entity corresponding to a SCADA system object representing plant equipment. The system includes an equipment model builder (EMB) that receives a set of configured UCO information for a modeled piece of plant equipment in a SCADA system. The EMB extracts relevant MES information from the utilization capability object and invokes an application interface on an MES database to create a corresponding entity (e.g., a database element). Another aspect of the disclosed system and methods involves the enhancement of a SCADA system object, through a new MES facet, to support acquiring and reporting equipment status received via the SCADA system to a corresponding MES entity. A raw reason code configuration interface is provided by UCO configurator computer software executed on a computer. Each raw reason code is associated with a prioritized logical expression defining circumstances under which the reason code becomes true.

1. A method of updating a manufacturing execution system (MES) database to include an MES entity corresponding to equipment modeled by a corresponding supervisory control and data acquisition (SCADA) system object, the method comprising:
providing a utilization object associated with the SCADA system object, the utilization object having an executable that, when executed, applies collected status data for the SCADA system object to a set of configured logical expressions to render a current raw reason code for the utilization object, the utilization object containing MES entity configuration information; extracting MES entity configuration information from the utilization object; invoking an interface functionality on the MES database to create the MES entity; providing a link between the utilization object and the MES entity; generating a second MES entity corresponding to a parent object of the SCADA system object; and monitoring SCADA system object performance and logging SCADA system utilization events by the first or second MES entity.
