采用SPC3的智能型PROFIBUS-DP现场总线接口的开发

Development of Intelligent PROFIBUS-DP Fieldbus Interface with SPC3

本文从开发的角度探讨了PROFIBUS－DP通讯接口卡软件及硬件的实现方法，并简单的介绍了PROFIBUS－DP状态机的工作原理。实验表明，软件及硬件设计是合理的，完全达到了预想的结果。

In this article,designing method of the software and hardware is discussed about PROFIBUS-DP interface card in terms of the development,and it is introduced simply how PROFIBUS-DP state machine runs.Experiments indicate that design of the software and hardware is reasonable and gets an expected result.
