This library was created to make it easier to create communication between devices using ModBus RTU protocol, based on RS485 wiring. As it state in the title, library is written only for handling ...

[导读]在工业自动化领域，Modbus协议凭借其开放性和易用性成为设备通信的"通用语言"。然而，当工程师面对Modbus RTU、ASCII和TCP三种变体时，如何根据具体场景做出最优选择？本文将从编码机制、通信效率、错误检测等核心技术维度展开对比分析，揭示三种协议在 ...

[导读]在工业物联网设备部署中，Modbus通信故障是导致系统停机的首要原因之一。据统计，超过60%的现场问题源于通信配置错误或数据解析异常。本文从嵌入式系统开发视角，系统阐述Modbus通信调试的方法论，结合实际案例解析如何高效定位并解决从物理层到 ...

Written in Rust, the PyApp utility wraps up Python programs into self-contained click-to-run executables. It might be the easiest Python packager yet. Every developer knows how hard it is to ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet/Wi-Fi). Designed for use in farms, ...
