Abstract:
1. An interdependency modeling method for controlling a batch process with an industrial automation system, comprising: evaluating during runtime an input parameter expression residing in a level of a supervisory system of the industrial automation system to determine a value of the input parameter expression, wherein the input parameter expression is based at least in part on a subscription to a data reference residing at or above the level of the supervisory system where the input parameter expression resides, and wherein the input parameter expression updates continuously; 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; 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, wherein the output parameter expression updates based on a trigger; and presenting a value of the output parameter.
