S1-S5 都是相关参数，D2是执行状态反馈，D2.0 D2.1 D2.2 分别是执行中，OK完成，NG完成。 手册给的注意事项: 请勿在ADPRW指令完成前将驱动触点置为OFF。 根据驱动状况，ADPRW指令通信开始的时间不同。使用单独ADPRW指令驱动时，通信即时开始。同时使用多个ADPRW指令 ...

Abstract: The CAN (Controller Area Network) and Modbus RTU protocols are both popular standards and have long been widely used in industrial systems. There are some difficulties and challenges in data ...

除了常规的数据采集，Modbus RTU 还有哪些不寻常的“高阶玩法”？下面分享几个有意思的用法。 在仅支持 Modbus RTU 协议的串口连接下，可通过 HMI 读取 U 盘文件并传输至 PLC，用于更新工艺数据或程序。文件通常为几KB至几十KB，小于 PLC 常规可用内存。 实现的核心 ...

[导读]Modbus RTU作为工业自动化领域的经典通信协议，凭借其简单可靠、抗干扰能力强的特性，广泛应用于变频器、PLC、传感器等设备的互联。本文以变频器通信为场景，深度解析Modbus RTU的帧结构设计与调试要点，为工程师提供可落地的技术指南。 Modbus RTU作为 ...

[导读]在工业物联网场景中，Modbus RTU与TCP协议转换是连接传统设备与现代系统的关键技术。某汽车制造厂通过协议转换网关，将200台使用Modbus RTU协议的焊接机器人无缝接入MES系统，实现生产数据实时监控，故障响应时间缩短至15秒内。本文将结合真实案例，解析 ...

该项目基于睿擎平台，开发了一款高性能工业物联网数据网关，实现Modbus RTU协议与MQTT协议的双向高效转换。该方案为传统工业设备在不改变原有功能和硬件结构的前提下，快速接入物联网提供了可靠且经济的技术路径。 本项目使用阿里云服务器部署EMQX MQTT Broker ...
