Development of a Laboratory Stand to Study of Industrial Protocols

The article discusses the development of a laboratory stand for the study of industrial network protocols ModBUS, ProfiNET and EtherCAT based on a single-Board raspberry Pi 3 Model B+ microcomputer. We also consider the integration of a new direction of the Internet of things (IoT), which is developing in the modern world, into the protocols of industrial control systems. After developing the module, one should conFigure and conFigure the equipment for successful laboratory work. The communication is configured using the ModBUS Protocol, and the frequency Converter is configured to be controlled from a microcomputer according to the RS-485 standard. The correct operation of the ProfiNET Protocol for communication with the PLC is configured. An example of developing a SCADA system from a company using CoDeSyS 3.5 software from 3S-Smart Software Solutions GmbH is given. The relevance of this work lies in the fact that the most energy efficient, productive, lightweight, inexpensive, compact singleBoard microcontroller Raspberry Pi 3 is used, which is often able to solve almost all the similar problems as industrial models of programmable logic controllers. The single-Board Raspberry Pi 3 Model B+ microcomputer is an open platform, for which many libraries are created, with the ability to connect various additional devices. The microcomputer is being upgraded by manufacturing additional modules, which include stepper motor control drivers, sensors, relay modules, and communication modules.
