AUTOMATED PROGRAMMING SYSTEM FOR INDUSTRIAL CONTROL USING AREA-MODEL

A development tool for control programs for industrial controllers develops an area-model detailing equipment and phases of operation of the equipment of a controlled process. This area-model is used as a framework for integrating reusable program fragments together into a cohesive control program. The area-model provides a naming convention for otherwise conflicting variables of the reused control components that preserves the identity of the control variables for subsequent programming. The renaming convention may be tracked so that other program portions stored together with the control program fragments in a library of object templates may be interconnected through the same or other editing systems.
