摘要
工业控制已从单机控制走向集中监控、集散控制,工业控制器网络化为控制管理提供了方便;文章提出一种在工业控制中采用USB接口构建Modbus协议通信网络系统,分析了两者的特点,给出了USB接口主机识别标准和自定义设备驱动实现硬件连接,定义了USB设备上的Modbus协议消息帧格式;实验表明,该方法可为工业控制提供一种更加简单、便利及高速的通讯组网手段。
In the industrial control, the network of industrial controllers provides much convenience for the control management. A communication network system that adopts the USB interface to implement the Modbus protocol in industrial control is presented. The features of the Modbus protocol and the USB interface are analyzed. The hardware connections of the standard and user-defined device driver that are identified by the USB interface of the host computer are given. The format of the Modbus protocol frame on the USB device is defined. The experiment results indicate that the presented method provides a simpler, more convenient and faster means for communication of the industrial control network.
