Abstract: The present disclosure relates to condition monitoring of wireless networks in industrial plant, wherein a wireless network has two or more wired gateways and a plurality of access nodes connected wirelessly with at least one wired gateway. Here, each access node is associated with at least one field device of the industrial plant. The condition monitoring is performed with an industrial device connected with the two or more wired gateways. The condition monitoring comprises periodically receiving information associated with packet transfer, channel access, and connection links for each node of the plurality of access nodes and each wired gateway. One or more parameters are estimated based on the received information, to determine connectivity status of the field devices in the industrial plant. The connectivity status is rendered on a user interface of an industrial device.

Abstract: The invention relates to managing a plurality of subsystems of a process plant. The process plant is controlled using a Distributed Control System (DCS) with a plurality of databases distributed within the process plant, wherein each database comprises information corresponding to at least one subsystem of the plurality of subsystems. The method comprises receiving a query at a human machine interface of the DCS, wherein the query is of a predetermined type and is associated with at least one of an operation and health of a subsystem. The method further comprises identifying at a server of the DCS, a database comprising information corresponding to the subsystem. Furthermore, the method comprises processing the query based on the information corresponding to the subsystem. In addition, the method comprises utilizing the DCS to control the operation of the subsystem by controlling process parameters of the process in one or more subsystems.
