High-level object-oriented programmable controller programming interface

This paper reports the development of a Automatic Programmable Controller Programming System Prototype. This windows-based system uses the concept of object-oriented paradigm to specify the control logic. This object-oriented specification is automatically translated to an specific Programmable Controller Programming language. Actually, the system can automatically generate a subset of the PLC5 programming language. Through this type of system, productivity of the programming activity is increased, specifically in environments where a large number of different Programmable Controllers coexist. Portability of the developed control software is also guaranteed, because a common description can be translated to different formats. The system is being written using Pascal with Objects and Arity Prolog.
