Abstract

The present invention relates to a system and methodology facilitating flexible resource distribution in an industrial control environment. A query component is provided to determine one or more system resources from a networked industrial controller system, wherein the resources can include listings of applications, configurations, variable settings, and performance capabilities associated with a controller. Upon receiving available resource listings from various control devices, a distribution component can update the devices based in part on the resource listings and according to various criteria. A configuration component can be utilized in the controller system to provide network updates of controller parameters and to facilitate automated protocol selections when interacting with out-of-network devices. An analysis component can interact with the query, distribution, and configuration components to support higher-level decision-making in the resource distribution and allocation process.

Claims

1. A method to facilitate resource distribution in an industrial controller system, comprising:

automatically querying a plurality of resources from a networked industrial control system;

automatically analyzing the plurality of resources to determine an available resource, the analyzing comprising (i) at least one of rules-based determining, statistical determining, probabilistic determining, or inference-based determining, and (ii) analyzing based on one or more classification models constructed to learn one or more data patterns in order to generate probabilities that predict a possible future data pattern; and

distributing the available resource within the networked industrial control system to facilitate a coordinated control process.

2. The method of claim 1, the analyzing based on one or more classification models includes analyzing based on at least one of Support Vector Machines (SVM), Naï

ve Bayes, Bayes Net, decision tree, similarity-based, or vector-based models.

3. The method of claim 1, the statistical determining includes at least one of averaging, determining based on standard deviations, comparing, sampling, determining based on frequency, or determining based on periodicity determinations.

4. The method of claim 1, the probabilistic determining comprising determining a performance condition based on a general probabilistic estimate comprising monitored evidence of an input pattern, the general probabilistic estimate is stated as:

Pr(Cp|E₁, E₂, . . . E_J);

wherein Pr is a probability, Cp relates to a monitored performance condition given evidence E relating to differences from monitored patterns, and J is an integer.

5. The method of claim 4, the probabilistic determining further comprising predicting a likely future outcome based on monitored evidence that includes data on consistency with a previous pattern.

6. The method of claim 4, the probabilistic determining further comprising triggering an internal event based upon the general probabilistic estimate being above a predetermined probability threshold.

7. The method of claim 1, the inference-based determining includes constructing inference models for analyzing at least one of multiple events or unrelated events.

8. The method of claim 1, further comprising performing at least one of a load balancing operation, a data transform operation, or a resource deployment operation.

9. The method of claim 1, further comprising at least one of automatically configuring system updates, updating system clocks via web services, or automatically selecting at least one of a plurality of communication protocols.

10. The method of claim 9, the selecting at least one of the plurality of communication protocols includes at least one of translating from one network protocol to at least one other network protocol, or activating a remote switch to facilitate communications between networks.

11. The method of claim 9, the configuring the system updates comprises configuring the system updates to occur at times that are at least one of automatically determined and or scheduled as part of a routine activity.

12. The method of claim 1, further comprising automatically configuring at least one Extensible Markup Language (XML) schema to communicate with the plurality of resources.

13. The method of claim 12, further comprising automatically configuring the at least one XML schema to communicate the available resource.

14. The method of claim 1, further comprising automatically propagating the available resource between the networked industrial control system and a remote system.

15. A system to facilitate resource distribution in an industrial controller system, comprising:

means for automatically acquiring a plurality of resources from a networked industrial control system;

means for analyzing the plurality of resources to determine an available resource, wherein the means for analyzing comprises means for learning data patterns to generate probabilities that predict possible future data patterns using at least one of a rules-base determination, a statistical determination, a probabilistic determination, or an inference-based determination; and

means for deploying the available resource within the networked industrial control system to facilitate a distributed control process.
