Profibus _ DP slave station based on reworks system

The invention provides a profibus _ DP slave station based on a reworks system. The profibus _ DP slave station based on the reworks system comprises a CPU platform and a profibus _ DP module. Data istransmitted to the profibus _ DP module through the CPU platform so as to carry out data interaction with the profibus _ DP master station. A user does not need to care about details of underlying hardware and an operating system, main energy is focused on development of a user application program, a sharp embedded real-time operating system is used in a CPU, and the real-time performance of tasks is guaranteed. 本发明提供了一种基于reworks系统的profibus_DP从站，包括：CPU平台和profibus_DP模块；通过CPU平台将数据传入profibus_DP模块与profibus_DP主站进行数据交互。本发明用户不需关心底层硬件及操作系统的细节，使主要精力集中在用户应用程序的开发上，CPU中使用锐华嵌入式实时操作系统，保证了任务的实时性。
