Modbus是一种用在工业自动化的主从协议,也可以用在别的地方,比如智能家居。 Modbus一般使用 rs-232 或者rs-485 协议作为物理层(也叫modbus串口),modbus 通过以太网或者WiFi (也叫Modbus IP)使用 TCP/IP 。 最新的版本库允许arduino作为从机使用,支持modbus串口和modbus ip。更多的关于modbus的信息可以在这里...

ModbusSlave library for Arduino This Modbus RTU slave library uses callbacks to handle modbus requests for one or multiple slave ids. Handler functions are called on modbus a request, and the users can implement them within their sketch.
在这里,Arduino Uno有两个按钮和一个电位器,用于将Modbus Master Arduino的值发送到Modbus Slave软件。 为了在Arduino UNO中使用Modbus,使用库。该库用于通过RTU协议与RS-485 Modbus主站或从站通信。下载Modbus Master并按照Sketch-> include library-> Add .zip Library在草图中添加库。 本文末尾处给出了完整的代码...

The Modbus protocol includes several function codes, each with a specific purpose, such as reading and writing data, controlling devices, and more. There is an official library from Espressif called ESP-Modbus that adds support for this protocol on ESP32 microcontrollers for industrial applications....
