Publication number: 20220100922Abstract: For predicting industrial automation network performance, a method generates algorithm parameters in a first standard format for a network calculus model from design data for a network implementation. The method generates the network calculus model from the algorithm parameters. The network calculus model models worst-case performance for the network implementation. The method generates model parameters in a second standard format for a network simulation model from the design data. The method generates the network simulation model from the model parameters. The network simulation model models probabilistic performance for the network implementation. The method executes the network calculus model to determine network calculus results. The method executes the network simulation model to determine network simulation results. The method determines a system policy difference between the network calculus results, the network simulation results, and the system policy.Type: ApplicationFiled: September 29, 2020Publication date: March 31, 2022Inventors: Yi Yu, Dayin Xu, Mark R.

Patent number: 8959399Abstract: An industrial controller module (13a) is provided with a routine of program instructions (29a) for storing a log of I/O table state changes (31) in a defined portion of memory (23). Upon the occurrence of a trigger event, a file of the state changes (37) is saved in the memory (23). Each entry (32) in the log of I/O table state changes (31) includes a timestamp (33) and values of each word of I/O state data (36) that changed at a time of the timestamp. Logs of state change data (16a), including timestamp data can also be saved for intelligent sensors and actuators (16) and uploaded with the log of controller processor state data (31) to a computer (20) with a diagnostic program (21a) for playing back the state changes and synchronizing changes of the intelligent sensors and actuators (16) with changes of the controller processor module (13a).Type: GrantFiled: November 19, 2013Date of Patent: February 17, 2015Assignee: Rockwell Automation Technologies, Inc.Inventors: Robert Guenther, Steven A. Zuponcic, Kenwood H. Hall

Patent number: 8726091Abstract: A system for troubleshooting control programs employs an event log that captures the values of inputs to outputs from the control program only at event times determined by changes in input or output data. The program allows the event log to be reviewed in jumps to only events which cause a change in output value of an instruction or particular change in output value of a particular instruction, greatly simplifying the troubleshooting process. The event log records a particular instruction instance associated with the event permitting the operation of the program to be studied in reverse order. The event log may also record a timestamp of the event allowing time stamped data from different devices to be synchronized with the review of the events.Type: GrantFiled: June 24, 2011Date of Patent: May 13, 2014Assignee: Rockwell Automation Technologies, Inc.Inventors: Robert Guenther, Steven A. Zuponcic, Kenwood H. Hall

Publication number: 20120265322Abstract: An input module for an industrial controller is configurable to simplify setup and commissioning. The input module includes input terminals configurable, for example, as a counter input. Still other input terminals may be configured to trigger events as a function of the input signals present at the terminals. Time signals corresponding to transitions in state of the input terminals, triggering of events, or operation of the counters may be recorded. The input module is further configurable to transmit data back to the processor or to transmit data directly to another module in the industrial control network.Type: ApplicationFiled: April 10, 2012Publication date: October 18, 2012Inventors: Bret S.
