摘要
Modbus协议作为一种开放的协议标准已经广泛应用于电能监测仪表系统中。在深入研究分析Modbus RTU协议的基础上,设计了利用西门子IPC427串口读取Modbus RTU数据的方法,解决了IPC427C自身不支持Modbus RTU协议的缺陷,并得到了良好的应用。
Modbus protocol is an open protocol standard which has been widely used in power monitoring instrument.Based on the in-depth research and analysis of the Modbus RTU protocol,this paper designs the method of Siemens lPC427 read Modbus serial RTU data,and solves the defect of lPC427C itself does not support the Modbus RTU protocol,and get good application.
