METHOD AND SYSTEM TO INCREASE PROCESSING CAPABILITY OF FIELD DEVICES IN AN INDUSTRIAL CONTROL SYSTEM

摘要

A method and system for scaling processing capability of a field device in an industrial control system (DCS) using a processing sub-system is disclosed. The DCS includes field devices, input-output devices, a controller, and a server. The method includes a step for configuring a virtual field device object in the processing sub-system using one or more functional components from a plurality of functional components, and a field device identifier tag of a field device in the industrial control system. The method further includes receiving measurement data from the field device in the processing sub-system; and processing the measurement data in the processing sub-system by the virtual field device object corresponding to the field device, to generate processed field device data. The method then includes a step for communicating the processed field device data using one or more pre-configured communication interfaces to the DCS.
