Krishna R. Mendu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10459413
    Abstract: Controlling and communicating with separate sets of industrial process control devices via separate data protocols simultaneously with a single processing device that utilizes redundancy and task-splitting to increase availability. An exemplary system includes a device integrator processor configured to receive and transmit electronic data via a plurality of protocols simultaneously. In one form, the device integrator processor includes a primary module that primarily controls communications and synchronizes itself with a shadow module of the processor. In another form, the processor includes multiple cores that each control a set of devices. Moreover, the cores implement a redundancy scheme.
    Type: Grant
    Filed: October 26, 2017
    Date of Patent: October 29, 2019
    Assignee: Schneider Electric Systems USA, Inc.

  • Patent number: 8516296
    Abstract: A system and method for interfacing redundant devices to a distributed control system, includes a first and second redundant field bus modules communicably coupled to the distributed control system and to one another via switches. A pair of redundant field devices are coupled to the switches, one FD having an address. The FBMs adopt respective roles as master FBM and tracker FBM, so that the master FBM is configured to capture data from the one FD using the address, and to pass any data changes periodically to the tracker FBM, through the switches. The master FBM is configured to point to the other field device in the event the other field device has assumed the address. The FBMs are configured to switch roles in the event communication is disrupted between the master FBM and the FD having the address.

  • Patent number: 7877625
    Abstract: A system and method for interfacing redundant devices to a distributed control system, includes a first and second redundant field bus modules communicably coupled to the distributed control system and to one another via Ethernet switches. A pair of redundant field devices are coupled to the Ethernet switches, one FD having a floating IP address. The FBMs adopt respective roles as master FBM and tracker FBM, so that the master FBM is configured to capture data from the one FD using the floating IP address, and to pass any data changes periodically to the tracker FBM, through the Ethernet switches. The master FBM is configured to point to the other field device in the event the other field device has assumed the floating IP address. The FBMs are configured to switch roles in the event communication is disrupted between the master FBM and the FD having the floating IP address.
