Abstract: The present invention provides a method and system for data transmission in a computer network. The method includes sending data with a first structure to a connector, the connector coupled between the front-end and the back-end, the data being either from the front-end or the back-end; and mapping the data to a second structure by the connector, such that a change in a configuration of at least one control point at the back-end is transparent to the front-end. In the preferred, the method includes an additional device, a connector, that serves as a gateway between the enterprise and the control network. The enterprise defines structures, data points, that it prefers to use and configures the gateway to use them. From then on, communication between the enterprise and the connector uses those structures. The enterprise also configures the gateway to communicate with the desired elements of the control network by defining input/output points.
