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!

1. 完成时/分/秒的依次显示并正确计数,利用六位数码管显示;
2. 时/分/秒各段个位满10正确进位,秒/分能做到满60向前进位,有系统时间清零功能;
3. 定时器:实现整点报时,通过扬声器发出高低报时声音;
4. 时间设置,也就是手动调时功能:当认为时钟不准确时,可以分别对分/时钟进行调整;
5. 闹钟:实现分/时闹钟设置,在时钟到达设定时间时通过扬声器响铃。有静音模式。
-1. Completed/min/sec display and correctly followed by counting, using six digital tube display 2. When/min/sec in the paragraphs of the correct 10-bit binary full, s/sub can do to advance the age of 60-bit, systematic function of the time cleared 3. timers: realize the whole point of time, by the time the level of sound from loudspeakers 4. time settings, which is manually adjusted when the function: When the clock does not consider accurate, they can respectively sub/clock adjustments 5. alarm clock: the realization of sub-/ when the alarm clock settings, settings in the clock arrival time ringing through the loudspeakers. There are silent mode.
