The standard 'environment' for Modbus protocol is RS485/422/232. The typical structure of an automation system that uses Modbus as its basic protocol is shown below. The field level is the level of interaction between sensors and controllers or sensors and the server. The middle level is the level of controllers - devices that collect data and control the technological process. Modbus is a common protocol used in automation systems at the middle and lower (field) levels. Debugging of automation systems based on Modbus devices.If not, below you will find a short introduction into Modbus. If you are familiar with the architecture of the protocol, you can jump right to the description of Modbus software.

In this article, we'll cover the key features of the existing software and hardware solutions for testing and debugging devices and networks based on Modbus protocol. All this ensures the growth of Modbus popularity among amateurs and professionals. The development of such projects as Arduino and Raspberry Pi has significantly increased interest in tasks related to robotics and automation. The protocol serves for connecting equipment of various types to a home computer as well. Modbus is a communication protocol commonly used in industrial automation systems, smart home systems, automated networks of small objects (warehouses, greenhouses, etc).
