中文摘要:
      针对控制器智能化、网络化的发展趋势,为了使具有RS485/RS232接口的控制器方便地接入PROFIBUS现场总线网络,基于C8051F020单片机,研制了以西门子公司的协议芯片SPC3为基础的PROFIBUS DP从站。首先介绍了PROFIBUS通信的基本原理,然后详细论述了硬件的几个组成部分的功能,对软件的整体结构及部分模块进行了论述,同时还给出了抗干扰的几种措施,最后给出了实验结果。实验结果表明设备间通信正常,可以应用于设备数据采集、执行和控制等,实现RS485/RS232设备与PROFIBUS现场总线的无缝互联。
English Summary:
      With the development of intelligence and network, and to access controller with RS485/RS232 interfaces to PROFIBUS field bus networks expediently, a PROFIBUS DP slave station based on the C8051F020 MCU by using the Siemens protocol chip SPC3 is developedThe fundamental of PROFIBUS is introduced first, then the functions of the hardware are discussed in details, and the configuration and some modules of the software are also expositedSeveral anti jamming measures are presented as wellFinally, the experiment result given out indicats that the normal communications are achieved between equipments , and the device can be used on equipments for data collection, control and implement, thus the jointless interconnection between RS485/RS232 equipment and PROFIBUS is realized.
