对于工业4.0中现代复杂生产过程的开发，有效地使用基于Petri网的先进数学模型是合适的。由于其在离散事件系统建模中的多功能性，Petri网是为数字化生产系统创建新平台的重要支持。本文的主要目的是设计一个新的软件工具，用于使用Arduino和类似的微控制器对离散事件和混合系统进行建模和控制。为了完成这些任务，提出了一种基于Petri网的新工具PN2ARDUINO，可以与微控制器通信。与微控制器的通信基于修改后的Firmata协议，因此，控制算法可以在支持这种协议的所有微控制器上实现。开发的软件工具在实验室系统的控制中得到了成功的验证。此外，它还可以用于教育和研究目的，因为它为设计混合和主要是离散事件系统的控制算法提供了图形环境。提出的软件工具可以改善网络物理系统（工业4.0）的教育和实践。
For the development of modern complex production processes in Industry 4.0, it is appropriate to effectively use advanced mathematical models based on Petri nets. Due to their versatility in modeling discrete-event systems, Petri nets are an important support in creating new platforms for digitized production systems. The main aim of the proposed article is to design a new software tool for modeling and control of discrete-event and hybrid systems using Arduino and similar microcontrollers. To accomplish these tasks, a new tool called PN2ARDUINO based on Petri nets is proposed able to communicate with the microcontroller. Communication with the microcontroller is based on the modified Firmata protocol hence, the control algorithm can be implemented on all microcontrollers that support this type of protocol. The developed software tool was successfully verified in control of laboratory systems. In addition, it can be used for education and research purposes as it offers a graphical environment for designing control algorithms for hybrid and mainly discrete-event systems. The proposed software tool can improve education and practice in cyber-physical systems (Industry 4.0).
