  • Patent number: 8417506
    Abstract: A tool for simulating an industrial control system is provided. The tool includes a simulation component to emulate one or more simulation models according to a simulated execution environment. A switch component is associated with the simulation component to selectively enable or disable variability in the simulation models.
    Type: Grant
    Filed: August 24, 2010
    Date of Patent: April 9, 2013
    Assignee: Rockwell Automation Technologies, Inc.
    Inventors: David T. Sturrock, Richard A. Morse
  • Patent number: 8019583
    Abstract: A simulation model can individually and selectively simulate sub-processes of a full-scale production system. Such a customized simulator can directly simulate all the processes of a system, any combination of processes of a system, or a single process of a system. The remaining processes of the system are left to be executed by an operator or equivalent software program. The model and corresponding information can be used for test, design, evaluation, adjustment, certification, and training purposes.

  • Patent number: 7827122
    Abstract: A data analysis system for utilization in an industrial environment comprises an aggregation component that aggregates data from multiple controllers on a factory floor. An analysis component performs data mining on the aggregated data to determine one of correlations between variables within the aggregated data and trends within the aggregated data. For example, the controllers can be programmable logic controllers, robotic controllers, and the like.

  • Patent number: 7647131
    Abstract: A system that facilitates determination of a sampling rate to utilize in connection with sampling data in an industrial environment comprises a receiver component that receives data from an I/O port of a controller. An analysis component automatically and dynamically determines a rate at which data associated with the I/O port is to be sampled based at least in part upon the received data. The system can further comprise a sampling component that samples data at the rate determined by the analysis component.

  • Patent number: 7487003
    Abstract: A system that tracks a lot of items being manufactured comprises a receiver component that receives control logics for manufacturing the lot, the control logics include information relating to number of items within the lot and number of items within sublots. A partitioning component automatically creates a plurality of virtual sublots that represent sublots being manufactured. A tracking component automatically tracks each of the sublots across multiple processes during manufacture of the items and associates tracking data with corresponding virtual sublots.

  • Patent number: 7463935
    Abstract: An industrial controller that can be utilized in an environment that supports message queuing comprises a receiver component that receives a message from a queue, wherein the message conforms to a message queuing protocol. A message queuing component communicatively coupled to the receiver component interprets the message and alters control logics within the controller based at least in part upon contents of the message. Furthermore, for example, the message queuing engine can be configured to generated messages that conform to the message queuing protocol.
