Modbus主从式总线的从机地址自动分配方法研究
资料介绍
以Modbus总线协议为例,设计了一种应用在主从式总线测控系统中的软件设置从机地址的方式。利用用户自定义广播命令结合虚地址二分法,收集从设备特征字符串,完成从机通信地址的自动分配。软件方法较硬件设定地址方法更加灵活、便捷、高效。
Based on Modbus protocol,the method is designed that refers to setting slave address by software applied in master-slave bus measurement and control system.To achieve automatic allocation of slave device communication addresses,it combines user-defined broadcast commands with virtual address dichotomy and collects slave device characteristic strings,which makes itself more flexible,convenient and efficient than the hardware address setting method.
