To design the control of automated systems, the designer must evaluate the performances of various solutions. Our research deals with the evaluation of distributed control architecture. We have chosen Colored Timed Petri Nets (CTPN) models for describe behaviors of each equipment of control and we use design/CPN simulation tool to assess response times performance. The aims of this paper are to build various Programmable Logic Controller (PLC) behavior models and to select the best according to our needs in performance evaluations. Various approaches for the creation of CTPN models are discussed. Some of them are based on synthesis techniques and some of them are based on an identification technique. Finally, a comparison method is presented. It will allow the designer to choose the right model for the simulation in the evaluation stage.
