Methods and apparatus to design collaborative automation systems based on data distribution service middleware

Abstract

Methods and apparatus to design collaborative automation systems based on Data Distribution Service middleware are described, which include a clustered automation platform having one or more control servers connected to a local area control network, and a plurality of self-contained process interface systems configured to receive electrical signals from one or more field instruments and forward resulting data via an uplink to a local area input/output network. The clustered automation platform also includes an input/output processing and inferential modeling server connected to the local area input/output network and configured to process input/output signals of the plurality of self-contained process interface systems. The clustered automation platform also includes real-time data distribution service control middleware configured to interconnect one or more process control applications, the one or more input/output processing and inferential modeling servers, the one or more control servers, the plurality of self-contained process interface systems, and one or more HMIs.
