In this dissertation, is presented a proposal of conversion of models of manufacturing cell (FMS) from Colored Petri Nets (CPN) to Ladder Logic Diagram (LLD). It explores the controlled CPN models - constructed using the methodology of supervisory Control Restrictions on Decomposed Colors (CRDC) - and not controlled models. It emphasizes the transformation of CPN not controlled for the LLD and ease for inclusion of control. The results described herein demonstrate that the methodology facilitates the work of a PLC programmer in LLD minimizing possible errors during the programming phase. To illustrate the methodology we developed a converter from CPN to LLD, produced in JAVA, in order to clarify the dynamic conversion environment. To validate the results of the converter, is controlled by PLC, a vertical articulated robot which works compared with and without supervision which had been firstly modeled in CPN without supervision, then applied to CRDC, the supervision and the conversion technique for LLD.
