Abstract: This work aims at designing and implementing logic control structures that allow a combination of the advantages of classical techniques for the development of programmable logic controller code and elimination of disadvantages such as the lack of formal validation. This paper introduces a method to automatically generate code for a programmable logic controller from a validated textual description of this kind of Petri net. A special compiler that generates code according to the standard IEC 1131 is discussed. The modeling and implementation of a logic control system for flexible assembly cell using the method describe servers as an example.

Keywords: colored Petri nets, logic controllers, standard IEC 1131.
