RAPID PROTOTYPING OF SEQUENTIAL CONTROLLERS WITH PETRI NETS

This paper focuses on the possibilities of a Petri net based rapid control prototyping (RCP) tool chain. P/T nets extended by interfaces and connected to an extended state model allow the description of typical programmable logic controller tasks. After a general introduction to RCP, the method is applied to the area of sequential control, and code generation for the chosen model is depicted. The paper closes with an example for a tool chain, demonstrated by system simulation and Software-in-the-Loop for a subsystem of a flexible manufacturing system in an industrial fieldbus environment.
