Abstract

An automation interface is provided for interacting with industrial controllers. The automation interface provides for programming, editing, monitoring and maintenance of industrial controllers programmatically from a local or remote location. The automation interface component is adapted to communicate with industrial controllers by integrating a computer process interface library into the automation interface component. The computer process interface library exposes the automation interface component to client application processes, so that the client application processes can communicate with the at least one industrial controller programmatically. The automation interface is provided with functionality for downloading, uploading and programming of control programs to the processors of the industrial controllers.

Claims

1. A system that facilitates interaction with an industrial controller, comprising:

an automation interface component that facilitates communications with an industrial controller to facilitate uploading to and downloading from the industrial controller a control program, and editing of the control program while in the industrial controller; and

a computer process interface library that comprises object-oriented based objects and classes that are associated with the automation interface component, the computer process interface library exposes the automation interface component to a client application process to facilitate programmatical communications with the industrial controller.

2. The system of claim 1, wherein the library is accessed via at least one of a local procedure call (LPC) and a remote procedure call (RPC).

3. The system of claim 1, wherein the objects and classes form a tree of objects and classes that are accessible through a top-level application object.

4. The system of claim 3, wherein a call to the application object creates an instance of an associated class in memory of the industrial controller.

5. The system of claim 3, wherein the objects and classes include a project object that is accessible via the application object via one or more methods.

6. The system of claim 1, wherein the objects and classes include a processor object that is associated with a current project object.

7. The system of claim 1, wherein the objects and classes include a program files collection object that represents all program files in a project.

8. The system of claim 1, wherein the objects and classes include a data files collection object that represents data files associated with a project.

9. The system of claim 1, wherein the automation interface component facilitates editing of data table values stored in the industrial controller.

10. The system of claim 1, wherein the computer process interface library is compiled as an executable file that is processed in the automation interface component.

11. The system of claim 1, wherein the objects and classes include an applications object, a project object, and a processor object, each of the objects viewable via a user interface.

12. The system of claim 1, wherein the objects and classes are processed using a macro.

13. A computer readable medium having computer-executable instructions for performing a method of interacting programmatically with an industrial controller, the method comprising:

providing an automation interface component that facilitates communications with the industrial controller; and

providing a computer process interface library of object-oriented based objects and classes in association with the automation interface component that facilitates programmatical communications with the industrial controller, which library facilitates exposing the automation interface component to a client application process to facilitate program management in the industrial controller by at least one of the acts of;

uploading a new control program to the industrial controller;

downloading an existing control program from the industrial controller; and

editing the existing control program while resident in the industrial controller.

14. The method of claim 13, further comprising providing a user interface that facilitates accessing at least one of an applications object, a project object, a processor object, a program file, and a ladder logic program.

15. The method of claim 13, further comprising at least one of the acts of:

instantiating an automation interface object in memory of the industrial controller from a remote location; and

removing the automation interface object from the memory.

16. The method of claim 13, further comprising retrieving a program file from the industrial controller and converting the program file to a ladder logic file.

17. The method of claim 13, further comprising the acts of:

uploading a first active object from a remote location to a memory of the industrial controller; and

retrieving a second active object from the memory.

18. The method of claim 13, further comprising accessing the objects and classes using macros.

19. The method of claim 13, further comprising manually controlling functions of the industrial controller via the automation interface component.

20. The method of claim 13, further comprising accessing the industrial controller via a web service.
