基于Modbus/RTU通信协议的工业控制系统
|
摘要
为了实现对日益增多的工业现场设备的集中管理,文中设计并实现了基于Modbus/RTU(远程终端单元)通信协议的工业控制系统。该控制系统通过RS-485串行总线标准,可实现对开关量和模拟量的控制。采用MFC(微软基础类库)编写上位机软件,在Modbus Tools环境中进行仿真与调试,最终实现了对LED灯、风扇和台达通讯型伺服驱动器ASDA-A2这三个原理样机的控制。测试结果满足设计要求。该控制系统可用于多节点二层通信网络的搭建,应用前景广泛。
In order to realize centralized management of increasing industrial devices,the article designs and implements an industrial control system based on the Modbus/RTU( Remote Terminal Unit)communication protocol. The system controls the switch and analog quantities through the RS-485 serial bus standard. The upper monitor was written by MFC( Microsoft Foundation Classes). The simulation and debugging were carried out in the Modbus Tools environment. Finally,the control of the three prototypes of LED,fan and Delta communication servo driver ASDA-A2 was realized. The results of test shows the system meets design requirements. The control system can be used to construct a two-layer communication network with multi-nodes,which has broad application prospects.
