A dead-simple command-line tool for reading and writing Modbus TCP and RTU registers. Beautiful terminal UI. No GUI, no config files, no bloat.

[导读]在老旧产线改造中，常有大量RS485 Modbus RTU设备（温湿度、电表、变频器）需要接入上位机或MES，但它们不支持TCP。此时用Raspberry Pi（树莓派）运行Modbus TCP↔RTU网关程序，既能做协议转换，又能充当边缘数据预处理节点。本文基于Raspberry Pi OS + pymodbus库，给 ...

The Wanderer 30A speaks Modbus RTU on its RS-232 port. To get it onto the network without buying Renogy's BT-1 dongle (or building an ESP32 + MAX3232), we use a serial-to-Ethernet gateway in ...

[导读]在产线设备中，PLC常作为主控单元负责工艺流程，FPGA作为高速算法加速/多路采集前端。两者之间通过Modbus RTU（RS485）或 ...
