Abstract

A catalog for storing externally defined graphic element (EDGE) definitions allows graphics developers and system designers to share customized and application-specific operator interface graphics. The catalog includes publishing functionality that allows a user to submit new graphic element definitions to the catalog together with instructions regarding how the graphic element definition is to be classified within a browsable hierarchy of industry-specific categories. Search and retrieval functionality allows an HMI developer to search for desired graphic element definitions using keyword-based searching or by browsing the classification hierarchy. Advanced search functions can generate or refine search criteria based on characterizing information polled from one or more of an operator interface application, an industrial control program, or networked field devices. The catalog can reside at a central network-accessible location or locally on a developer workstation to facilitate access to the stored graphic element definitions.

Claims

1. A system for sharing operator interface graphic element definitions, comprising:

a storage component configured to maintain one or more graphic element definitions in a hierarchical storage structure; and

an interface component configured to process a request to locate and retrieve a selected subset of the one or more graphic element definitions.

2. The system of claim 1, wherein the hierarchical storage structure comprises a plurality of nodes representing categories and respective sub-categories into which the one or more graphic element definitions are classified.

3. The system of claim 1, further comprising a query component configured to identify the selected subset of the one or more graphic element definitions according to at least one search criterion received in the request that defines the selected subset of the one or more graphic element definitions.

4. The system of claim 2, further comprising a browsing component configured to identify the selected subset according to a browse input received in the request that selects at least one of the categories or the respective sub-categories.

5. The system of claim 1, further comprising a retrieval component configured to retrieve the selected subset of the one or more graphic element definitions and to pass the selected subset of the one or more graphic element definitions to the interface component for transmission to a source of the request.

6. The system of claim 1, further comprising a publish component configured to receive a new graphic element definition submitted to the interface component and to store the new graphic element definition within the hierarchical storage structure.

7. The system of claim 6, wherein the publish component is further configured to extract metadata associated with the new graphical element definition and to classify the new graphic element within the hierarchical storage structure in accordance with the tag data.

8. The system of claim 7, wherein the metadata comprises at least one of industry information, category information, or sub-category information.

9. The system of claim 6, wherein the publish component is further configured to create a new node within the hierarchical storage structure if the metadata includes a new category or a new sub-category not existent within the hierarchical storage structure.

10. The system of claim 1, further comprising a notification component configured to transmit a notification to at least one client that a new version of a selected graphical element definition has been detected within the hierarchical storage structure.

11. The system of claim 3, further comprising:

an acquisition component configured to read at least one control data structure from a control program; and

an association component configured to generate the at least one search criterion based on the at least one control data structure and a predetermined graphics mapping defining at least one relationship between the at least one control data structure and at least one display object type.

12. The system of claim 11, wherein the predetermined mapping is associated with a human-machine interface application.

13. A method for managing reusable operator interface graphic element definitions, comprising:

storing one or more graphic element definitions in a searchable catalog in a hierarchical storage format; and

retrieving a selected subset of the one or more graphic element definitions in response to a received request.

14. The method of claim 13, further comprising:

configuring the hierarchical storage format to comprise a plurality of categories and sub-categories; and

associating the one or more graphic element definitions with respective browsable pathways through a subset of the plurality of categories and sub-categories.

15. The method of claim 13, further comprising identifying the selected subset of the one or more graphic element definitions based on at least one search criterion included in the received request.

16. The method of claim 14, further comprising identifying the selected subset of the one or more graphic element definitions based on at least one browse input included in the received request that selects at least a first category or a first sub-category from the plurality of categories and sub-categories.

17. The method of claim 13, further comprising sending the selected subset of the one or more graphic element definitions to a source of the request.

18. The method of claim 13, further comprising:

receiving a new graphic element definition;

extracting metadata from a metadata tag associated with the new graphic element definition; and

classifying the new graphic element definition at a location within the searchable category determined according to the metadata.

19. The method of claim 16, further comprising:

reading at least one control data structure from a control program;

generating the at least one search criterion based on the at least one control data structure and a graphical mapping defining an association between the at least one control data structure and at least one display object type.

20. A computer-readable medium having stored thereon computer-executable instructions that, in response to execution by a computer, direct the computer to:

create a browsable hierarchical classification structure configured to store one or more graphic element definitions; and

create an interface configured to locate and retrieve a selected subset of the one or more graphic element in response to a received request.
