Abstract

A method and apparatus for use with a plurality of resources integrated within a space for performing a process and a program run by a processor for controlling the process, the method for associating the program with the resources and comprising the steps of identifying at least a first reference point within the space, identifying the relative juxtaposition of at least a first resource with respect to the first reference point and associating the first resource with the program as a function of the relative juxtaposition of the resource to the reference point.

Claims

1. A method for use with at least a first network enabled resource and a second network enabled resource to be arranged to perform a process within a space, the first resource and the second resource each comprising an automation device capable of performing an automation function during the process, the method for validating likely correct first and second resource communications and comprising the steps of:

providing a first network address for the first resource and a second network address for the second resource;

providing a spatial rule set including rules that indicate probable relative first and second resource positions;

specifying that the first resource communicates with the second resource by including the second network address when communicating;

identifying a relative juxtapositions of the first resource;

identifying a relative juxtaposition of the second resource;

associating the relative juxtaposition of the first resource with the first network address;

associating the relative juxtaposition of the second resource with the second network address;

determining if the relative juxtapositions of the first and second resources are consistent with the rule set; and

where, the relative juxtapositions of the first and second resources are inconsistent with the rule set, performing a secondary function.

2. The method of claim 1 wherein the rule set indicates a maximum distance between the second resource and a reference point within the space such that, when the distance between the reference point and the second resource is greater than the maximum distance, the relative juxtapositions of the first and second resources are inconsistent with the rule set.

3. The method of claim 2 wherein the reference point is the location of the first resource.

4. The method of claim 1 wherein the secondary function is to indicate that the specified communication is improbable.

5. The method of claim 1 wherein the method is performed in real time as a resource is added to a sub-set of resources to perform the process.

6. The method of claim 5 wherein the environment includes an automated manufacturing facility.

7. The method of claim 1 wherein the method is performed in batch after a sub-set of resources has been configured to perform the process.

8. The method of claim 1 further including the steps of correlating network addresses with space locations and wherein the step of identifying the relative juxtapositions of the first and second resources includes determining the locations of the first and second resources from the correlated network addresses and using the first and second resource locations to determine relative positions of the first and second resources.

9. The method of claim 1 wherein the environment includes an automated manufacturing facility.

10. A method for use with at least a first network enabled resource and a second network enabled resource to be arranged to perform a process within an environment, the first resource and the second resource each comprising an automation device capable of performing an automation function during the process, the method for validating likely correct first and second resource communications and comprising the steps of:

providing a spatial rule set including rules that indicate probable relative first and second resource positions for resources that communicate with each other and include at least one of a first network address and a second network address when communicating;

associating a relative position of the first resource with the first network address;

associating a relative position of the second resource with the second network address;

specifying a first spatial relationship between the first and second resources;

determining if the specified spatial relationship between the first and second resources is consistent with the rule set; and

where the specified spatial relationship between the first and second resources is inconsistent with the rule set, performing a secondary function.

11. A method for use with a plurality of network enabled resources to be arranged to perform a process, the plurality of resources each comprising an automation device capable of performing an automation function during the process, the method for validating likely correct resource communications and comprising the steps of:

providing a spatial rule set including rules that indicate probable relative resource positions;

correlating logical network addresses with environment locations;

specifying first and second network addresses for a first resource and a second resources, respectively;

specifying that the first resource communicates with the second resource using the specified network address for the second resource;

associating a relative position of the first resource and the second resource with the network addresses of the first and second resources, respectively;

using the network addresses of the first and second resources to determine the relative positions of the first and second resources;

determining if the first and second resource relative positions are consistent with the rule set; and

where the relative positions of the first and second resources are inconsistent with the rule set, performing a secondary function.

12. The method of claim 11 wherein the rule set indicates a maximum distance between the first and second resources such that, when the distance between the first and second resources is greater than the maximum distance, the relative positions of the first and second resources are inconsistent with the rule set.

13. The method of claim 12 wherein the step of performing a secondary function includes indicating an improbable resource configuration.

14. A method for use with a plurality of network enabled resources to be linked via a network within an environment to perform a process and a processor running a program to control the process, the program including at least one of a program input tag and a program output tag for each of the resources, the resources each comprising an automation device capable of performing an automation function during the process, the method for facilitating association of the tags and the resources and comprising the steps of:

associating a space within the environment with the process;

providing at least a first resource that includes the processor;

determining the location of the first resource within the environment; and

when the first resource is proximate at least a sub-space within the space, using the processor to automatically perform the steps of;

(i) identifying the resources to be positioned within the sub-space;

(ii) identifying the tags associated with the resources; and

(iii) indicating the tags associated with the resources.

15. The method of claim 14 further including the steps of, for at least one of the resources, identifying the resource to the network and indicating one of the tags via the first resource that is to be associated with the resource and, wherein, the method further includes the step of associating the identified resource with the indicated tag.

16. The method of claim 15 wherein the step of identifying the resource includes linking the resource to the network.

17. The method of claim 16 wherein the first resource includes a display and wherein the step of identifying the tags includes providing a list of the tags and the step of indicating one of the tags includes selecting one of the tags from the list.

18. The method of claim 15 wherein each of the resources is associated with a network address and wherein the step of associating includes determining the resource address and correlating the resource address with the tag.

19. The method of claim 18 wherein the step of claim 18 is repeated for each resource to be located within the sub-space.
