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.
