Autoconfiguring graphic interface for controllers having dynamic database structures

The present invention relates to process controllers. More specifically, the present invention relates to autoconfiguring graphic interfaces for remotely operable controllers. A controller is provided which allows an interface device to autoconfigure a graphic interface to reflect the configuration of the controller. The controller has a static memory and a dynamic memory. The static memory contains predefined memory elements which contain information on the number of control loops being controlled, the type of each control loop, and the location within the dynamic memory of a data grouping associated with each control loop. An interface device accesses the static memory to obtain the information necessary to display a graphic interface representative of the controller configuration, and to access appropriate data groups within the dynamic memory to update the graphic interface to reflect the status of the process.
