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.

1. A development tool for creating control programs executable on an industrial controller to control a controlled process, the development tool implemented on an electronic computer and comprising:an area-model developer generating an area-model representing physical equipment and phases of operation of the physical equipment used in the controlled process, the area-model linking phases of operation to the physical equipment in a hierarchy; a library providing a plurality of program fragments executable on the industrial controller to perform the phases of operation, the program fragments having control variables representing physical inputs or physical outputs communicating with the controlled process; and a program integration wizard receiving the area-model and the library and accepting input from a user to match program fragments from the library to phases of operation of particular equipment in the area-model to produce the control program and upon the matching to uniquely denote the control variables of all program fragments of the control program according to the hierarchy.
