Industrial controller automation interface
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.
1. An automation interface device comprising at least one processor, nonvolatile storage and a network adapter, the nonvolatile storage including a compiled executable file that is exposed to an application executed by the at least one processor, the compiled executable file including an automation interface comprising:

a library of semantically related functions providing access to the exposed program file object and control process data object,
a set of object classes specifying, for at least a class of exposed control process data objects, a set of one or more allowable and programmatically accessible monitoring and storage methods, and
wherein the automation interface is exposed to both an application executed by a remote processor on an industrial controller in communication with the automation interface device over a first network via the network adapter and a web service operating on a web server in communication with the automation interface device over a second network via the network adapter, wherein the automation interface device, the industrial controller, and the web server are separate devices.

exposing the compiled executable file including the automation interface to an application executed by a remote processor on an industrial controller in communication with the automation interface device over a first network via the network adapter;
exposing the compiled executable file including the automation interface to a web service operating on a web server in communication with the automation interface device over a second network via the network adapter, wherein the automation interface device, the industrial controller, and the web server are separate devices; and
wherein the automation interface comprises:
an object tree associated therewith specifying at least an exposed program file object and an exposed control process data object,
a library of semantically related functions providing access to the exposed program file object and control process data object, and
a set of object classes specifying, for at least a class of exposed control process data objects, a set of one or more allowable and programmatically accessible monitoring and storage methods.
9. The non-transitory computer-readable medium of claim 8 , the operations further comprising placing the automation interface into an invisible mode where no user interface is provided.
10. The non-transitory computer-readable medium of claim 8 , wherein the set of object classes also includes, for at least a class of exposed control process data objects, a set of one or more programmatically accessible events.
11. The non-transitory computer-readable medium of claim 8 , wherein the object tree specifies a data files collection object representing a collection of control process data objects.
12. The non-transitory computer-readable medium of claim 8 , wherein the web service is callable by a remote client through the Internet.
13. The non-transitory computer-readable medium of claim 8 , wherein the set of object classes also includes, for at least a class of exposed control process data objects, a set of one or more programmatically accessible methods for accessing and editing data values in the memory of an industrial controller via the network adapter.
14. The non-transitory computer-readable medium of claim 8 , wherein the set of object classes also includes, for at least a class of exposed control process data objects, a set of one or more programmatically accessible methods for accessing and editing a control program in the memory of an industrial controller via the network adapter.
15. A method, comprising:
exposing, by an automation interface device comprising at least one processor, a compiled executable file including an automation interface to an application executed by the at least one processor;
exposing, by the automation interface device via a network adapter, the compiled executable file including the automation interface to an application executed by a remote processor on an industrial controller in communication with the automation interface device over a first network;
exposing, by the automation interface device via the network adapter, the compiled executable file including the automation interface to a web service operating on a web server in communication with the automation interface device over a second network, wherein the automation interface device, the industrial controller, and the web server are separate devices; and
