Integrated nodes, computer readable media and program products, and computer-implemented methods for providing an integrated node for data acquisition, verification and conditioning, and for remote subsystem control

Abstract

Integrated nodes, such as programmable logic controllers, computer program products, computer readable media, and computer implemented methods are provided to allow a remote host to interface with a plurality of remote subsystems to thereby define an integrated node, and to provide for data acquisition, verification, and conditioning. An exemplary programmable logic controller includes a data acquirer configured to periodically acquire time-stamped data from each of the plurality of remote time-synchronized subsystems and archive the time-stamped data using the database server module, a data verifier configured to detect out-of-bounds measurements in the time-stamped data and to substitute the out-of-bounds measurements with new measurements, and a data reconciler configured to determine an operating state of the plurality of remote time-synchronized subsystems and to reconcile the plurality of verified measurements.
