摘要
该文介绍了单片机＋SPC3的从站接口的软硬件设计方法，并通过组态软件＋CP5611卡的方式和串口模拟主站两种方式搭建主站，测试从站的通信功能，同时为不同需求的开发者提供了较为合理的从站调试方法和报文分析。
The design methods of hardware and software of PROFIBUS-DP slave station with MCU＋SPC3 are introduced. With two methods of making master station about configuration software ＋CP5611 and serial simulations, the ways of testing communicate function about slave station are described, and the analysis of messages are provided in detail.
