摘　　要：介绍了Modbus协议的特点,分析了S7-200 PLC Modbus RTU主站协议库,确定了采掘设备控制器S7-200 PLC与矿用智能遥控接收机的数据通信采用Modbus RTU协议,实现了采掘设备与遥控装置的双向通信。应用结果表明,以S7-200 PLC为主站的Modbus通信,传输数据准确可靠,效果良好。The characteristics of Modbus protocol were introduced, and the protocol libraries of Modbus RTU master were analyzed. It made sure that Modbus RTU protocol was adopted in data transmission between S7-200 PLC and intelligent remote receiver used in coal mine, and realized intercommunication between equipment for excavation and remote device. The application indicated that Modbus communication took S7-200 PLC as master has reliability in data transmission and good effect.
