摘要
文中以ERTEC200P为核心完成PROFINET协议的主站构建,并且用STM32F401完成CAN、Modbus和EtherCAT等多种通信协议的数据交换,利用多CPU平台可以完成10Mbit/s的工业信息交换,同时设计出具有数字帧故障诊断功能的软件系统。搭建工业通信中最常用的PROFINET和Modbus数据交换平台,通过读取数据寄存器的数据验证工业交换机的功能。实验表明开发的嵌入式信息交换系统可以起到增强系统扩展性和数据高速交换的作用。
The ERTEC200P protocol was used to complete the construction of the master station PROFINET.In addition, STM32F401 is used to complete data exchange of CAN,Modbus,EtherCAT and other communication protocols.The industrial in formation exchange of 10 bit/s can be completed with multi CPU platform.At the same time,a software system with digital frame fault diagnosis function was designed.By building the most commonly used PROFINET and Modbus data exchange platform,the data of the data register was read to verify the function of the industrial switch.The experiment shows that the embedded informa tion exchange system can enhance the extensibility and data exchange of the system.
