Modbus RTU 通信协议作为工业领域的常青树，广泛应用于各类基于 RS485/232 串口的设备中。 然而，随着工业互联网的发展，SCADA 系统、上位机及 HMI 已逐渐普及以太网架构，甚至实现了向 Wi-Fi 无线通信的迭代。 在许多工厂中，现有的传感器、电表、温控器或部分 PLC ...

So, you want to learn Python? That’s cool. A lot of people are getting into it these days because it’s used for all sorts of things, from building websites to analyzing data. If you’re looking for a ...

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 ...

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 ...
