Method and system for control system redundancy

Abstract

A method and system for a redundant control system are provided. The control system includes a high speed network bus, a controller set communicatively coupled to the network bus wherein the controller set includes at least three Fieldbus controllers, and a Fieldbus linking device communicatively coupled to each of the at least three Fieldbus controllers in the controller set and to a Fieldbus network. The control system further includes a plurality of Fieldbus devices communicatively coupled to the Fieldbus network, where at least one of the controller set, the Fieldbus linking device, and the plurality of Fieldbus devices are configured to monitor outputs from the plurality of Fieldbus devices and determine an erroneous one of the monitored outputs.

Dependencies are inferred from the claim text.
