SYSTEMS AND METHODS FOR MODELING INTERDEPENDENCIES IN BATCH PROCESSES

摘要

According to various embodiments, an interdependency modeling method for controlling a batch process with an industrial automation system includes evaluating an input parameter expression residing in a level of a supervisory system of the industrial automation system to determine a value, transferring the value of the input parameter expression to a level of an equipment control system of the industrial automation system, transferring data from the level of the equipment control system to the level of the supervisory system, and evaluating an output parameter expression residing in the level of the supervisory system based on the data from the level of the equipment control system.

1. A non-transitory computer readable storage medium, comprising:
computer code disposed on the computer readable storage medium, wherein the code comprises instructions to:
evaluate, during runtime, an input parameter expression residing in a level of a supervisory system of an industrial system to determine a value of the input parameter expression, wherein the input parameter expression is based at least in part on a data reference residing at or above the level of the supervisory system where the input parameter expression resides;transfer the value of the input parameter expression to a level of an equipment control system of the industrial system;transfer data from the level of the equipment control system to the level of the supervisory system;evaluate an output parameter expression residing in the level of the supervisory system based on the data from the level of the equipment control system; andpresent a value of the output parameter.
