本文介绍了一种控制普通阀门的阀门控制器的设计方案，该阀门控制器带有工业现场总线PROFIBUS－DP 的接口，可以实现阀门的远程控制和网络控制。本文主要的着力点为介绍利用PROFIBUS－DP 专用芯片SPC3 开发PROFIBUS－DP 设备中需要注意的一些问题，包括硬件接口设计，有关PROFIBUS－DP 规范标准的一些设计要点，以及利用PROFIBUS－DP 诊断功能的方法。本文对设计其它Profibus DP从站节点有很好的参考价值!-This paper presents a general valve control valve controller design program The valve controller with industrial PROFIBUS-DP interface. The valve can be achieved remote control and network control. This paper mainly focus on the use of PROFIBUS-DP SPC3 ASIC development PROFIB U.S.-DP equipment necessary to pay attention to a number of issues, including the hardware interface design, The PROFIBUS-DP standards in a number of design features, and the use PROFIBUS-DP diagnostic function method. In this paper, the design of other Profibus DP slave nodes are of value!
