摘　　要：WB智能电量传感器与S7-PLC采用异步串行通讯,通过S7-200通讯口引脚及WB传感器RS485口端子排分配,以WB传感器通讯协议及S7-200CPU编程实现通讯。S7-200CPU编程包括初始化、读数据命令、向WB智能传感器发送命令、中断8端口0字符接受程序、读端口返回数据及处理。该通讯已在空调参数测试系统中应用。The asynchronous serial communication was used between WB intelligent senor and S7-PLC, its information was distributed through COM port of S7-200 PLC and RS485 port of WB Intelligent sensor. The communication was realized with the protocol of WB Sensor and the programming of the S7-200 PLC CPU. The programming of S7-200 CPU consists of the initialzation, reading command, writing command to WB intelligent Sensor, 0 character receiving program of interrupting eight ports, returning data and data processing. The communication was applied in the parameters test system of air condition.
