Conversion methodologies from Signal Interpreted Petri Nets to Ladder Diagram and C language in Arduino

With the advent of electronics in the last decades, automation is becoming a wide and strong area to be studied. Its applications go from industrial machinery and robotics processes to home illumination and security system processes. Electronic components are becoming more efficient, more productive, safer and cheaper, which justifies its growing usage. Inside automation’s area is an area called discrete event systems, which presents an organized and graphical way to represent these events through a tool called Signal Interpreted Petri Nets. The purpose of this paper is to formally define Signal Interpreted Petri Net and to develop two didactic methodologies to be used in laboratory classes: to convert Signal Interpreted Petri Net into Ladder Diagram for Programmable Logic Controller and to convert Signal Interpreted Petri Net into C language for Arduino microcontroller. These methodologies will be illustrated by applying the formal Signal Interpreted Petri Net’s definition on an example.
