Publication number: 20160292426Abstract: A method of transmitting high speed serial data with reduced levels of radiated emissions is disclosed. A transmitting device scrambles data utilizing a pseudo-random number sequence generator. Scrambling the data eliminates transmission of repeated data sequences. The transmitting device similarly scrambles idle pairs of data between data transmissions to eliminate an additional source of repeated data sequences. The scrambled and encoded data is transmitted to a receiving device. The receiving device also includes a pseudo-random number sequence generator. Synchronization of the two pseudo-random number sequence generators occurs by utilizing control characters of the data frame being transmitted. Each of the pseudo-random number sequence generators is configured to generate the same sequence of numbers and is initialized to start with a first number in the sequence of numbers corresponding to the first byte of data being transmitted or received.Type: ApplicationFiled: March 30, 2015Publication date: October 6, 2016Inventors: Anthony G. Gibart, Kenwood H. Hall, Robert E. Lounsbury

Publication number: 20160147579Abstract: An improved system for handling events in an industrial control system is disclosed. A module in an industrial controller is configured to generate an event responsive to a predefined signal or combination of signals occurring. The event is transferred to an event queue for subsequent execution. The event queue may also be configured to store a copy of the state of the module at the time the event is generated. The event queue may hold multiple events and each event is configured to trigger at least one event task. Subsequent events that occur during execution of the event task are stored in the event queue for later execution. An event, or combination of events, may trigger execution of an event task within the module, within the controller to which the module is connected, or within multiple controllers.Type: ApplicationFiled: November 26, 2014Publication date: May 26, 2016Inventors: Eric D. Decker, Kenwood H. Hall, Robert J. Kretschmann, Terence S. Tenorio, Scott A. Pierce, Bret S. Hildebran, Raymond R. Husted, Gregg Sichner, David M. Fort

Patent number: 9197576Abstract: The subject matter disclosed herein describes a method to allocate and prioritize data communications on an industrial control network. A transmission schedule including multiple priority windows and multiple queues is established. Each queue is assigned to at least one priority window, and each priority window may have multiple queues assigned thereto. A control device communicating on the control network transmits data packets according to the transmission schedule. Within each priority window, data packets corresponding to one of the queues assigned to the priority window may be transmitted. The data packets may be transmitted at any point during the priority window, but will only be transmitted if no data packet from a higher queue is waiting to be transmitted.Type: GrantFiled: November 15, 2010Date of Patent: November 24, 2015Assignee: Rockwell Automation Technologies, Inc.Inventors: Sivaram Balasubramanian, David A.

Patent number: 9152144Abstract: In a distributed directory configuration, different nodes can retain information pertinent an industrial control configuration. As information changes in one node, replicas of the information in other nodes can be updated. However, updating can take time and a query can be run upon the directory while nodes have conflicting information. Conflicting information can be identified and resolved such that a query obtains a correct answer.Type: GrantFiled: August 14, 2008Date of Patent: October 6, 2015Assignee: Rockwell Automation Technologies, Inc.Inventors: David A.

Publication number: 20150066469Abstract: Systems and methods that efficiently simulate controlled systems are presented. A simulation management component (SMC) controls simulation of a controlled system by controlling a desired number of nodes, each comprising a controller (e.g., soft controller) and a simulated component or process, which are part of the controlled system. The simulation can be performed in a step-wise manner, wherein the simulation can comprise a desired number of steps of respectively desired lengths of time. For each step, the SMC dynamically selects a desired clock (e.g., currently identified slowest clock) as a master clock for the next step. The SMC predicts a length of time of the next step to facilitate setting a desired length of time for the next step based in part on the predicted length of time. As part of each step, components can synchronously exchange data via intra-node or inter-node connections to facilitate simulation.Type: ApplicationFiled: November 5, 2014Publication date: March 5, 2015Inventors: Francisco P.

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.

Publication number: 20150019191Abstract: A simulation environment is provided for running a process simulation used to validate an industrial control program. The simulation environment exposes the I/O module configurations defined in the control program and retrieves module configuration information therefrom. This I/O module configuration information is combined with generic, module-specific I/O module profiles to create a pool of available controller I/O points, which can be selectively associated with I/O points in the simulation to create an I/O point mapping. During control program validation, simulated I/O data is exchanged between the process simulation and the I/O module instances in the controller in accordance with the I/O point mapping. A variation of these techniques for use with cloud-based emulations is also described.Type: ApplicationFiled: October 1, 2014Publication date: January 15, 2015Inventors: Francisco P.
