Patent number: 11720090Abstract: A method and system for assigning slot addresses to modules in a fault tolerant industrial control system includes a pair of backplane switches on each base. Each backplane switch is configured to communicate between one backplane and the modules located on the base and to communicate between backplane switches located at adjacent bases. A backplane switch on a bank master base first assigns a base address and slot addresses to itself. The backplane switches on each additional base initiate transmission of a base address request. A base address response, including a base address and slot numbers for the adjacent base, is transmitted after a base has its own address assigned. Each base repeats the process in sequence along the bank, incrementing the base address by one and the slot address by the number of slots on the base and passing the new base and slot addresses along the bank.Type: GrantFiled: November 20, 2020Date of Patent: August 8, 2023Assignee: Rockwell Automation Technologies, Inc.Inventors: Sivaram Balasubramanian, Chandresh Chaudhari, Kendal R.

Patent number: 10587730Abstract: An enhanced transfer of information using an industrial protocol system and method are disclosed. In one embodiment, an industrial automation system includes a serving device communicably coupled with a client device via an industrial data exchange protocol. The client device is configured to generate a service request in accordance with the industrial data exchange protocol, compress the service request, encapsulate the compressed service request in a request packet, and send the request packet to the serving device. The serving device is configured to receive the request packet, decompress the compressed service request, process the service request, gather a service response payload based on the service request, compress the service response payload, encapsulate the compressed service response payload into a response packet, and send the response packet to the client device.Type: GrantFiled: January 15, 2015Date of Patent: March 10, 2020Assignee: Rockwell Automation, Inc.Inventors: David Allen Johnston, Elmorris P.

Patent number: 10541917Abstract: A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.Type: GrantFiled: April 30, 2018Date of Patent: January 21, 2020Assignee: Rockwell Automation Technologies, Inc.Inventors: Sivaram Balasubramanian, Jonathan D.

Patent number: 10162783Abstract: A method and system for assigning slot addresses to modules in an industrial control system is disclosed. The modules are set up in a daisy chain topology. On power-up, a first module in the chain reads its slot address from a user configurable input or sets its slot address to a default value. The first module communicates to its immediate right neighbor using a special, one-hop message. The neighboring modules communicate to receive each other's information. The first module then sets an enable signal between the modules and sends a slot number to the neighbor in a firmware message. The neighbor checks if the enable signal is set and verifies that the slot number is a valid slot number. If so, then the neighboring module accepts the slot and repeats the same procedure to its next immediate neighbor, and so on until the last module.Type: GrantFiled: March 24, 2016Date of Patent: December 25, 2018Assignee: Rockwell Automation Technologies, Inc.Inventors: Chandresh R.

Patent number: 7908360Abstract: Systems and methods that correlate among disparate pieces of synchronized data, collected from an “internal” data stream (e.g., history data collected from an industrial unit) and an “external” data stream (e.g., traffic data on network services). A process trend component that determines/predicts an outcome of an industrial process and facilitates diagnostics/prognostics of an industrial system. Accordingly, relations among various parameters can be discovered (e.g., dynamically) and proper corrective adjustments supplied to the industrial process. Such enables a tight control and short reaction time to process parameters, and for a modification thereof.Type: GrantFiled: September 28, 2007Date of Patent: March 15, 2011Assignee: Rockwell Automation Technologies, Inc.Inventors: Martin George Gach, Timothy Siorek, Jonathan D.
