INDUSTRIAL CONTROLLER AUTOMATION INTERFACE

摘要

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. A method performed by an automation interface residing on a local server computer for facilitating communication between components of an automation system, the method comprising:
(a) establishing one or more classes of objects, including defining at least one attribute or method for each object; (b) assigning a project object to a programmable logic controller in communication with the local server computer, the project object being associated with at least one program file object residing on the programmable logic controller and at least one data file object residing on the programmable logic controller; (c) receiving a data request to upload control process data from a data file object, the data request specifying the control process data as an attribute of the project object or an object associated with the project object; and (d) based on the specified control process data attribute in the received data request, executing the data request with the programmable logic controller associated with the project object associated with the specified control process data attribute.
