基于PLC和显示控制屏的信息轮巡的显示方法设计

针对现代PLC工业系统数据信息繁多、结构复杂、综合显示控制屏显示功能有限的难题，在数据信息传统的显示方法的基础上提出轮巡的信息显示方法。通过编制PLC控制程序和显示控制屏页面程序，实现了系统状态信息在综合显示控制屏上的轮流切换显示。讨论了其具体实现算法，并将综合显示控制屏按该方法应用在山东引黄涵闸PLC测控系统中，获得了比较满意的效果。

Design of display method of information turning basing on PLC and synthetical display-control screen

Aiming at the difficulty that display function of synthetical Display-Control Screen is limited owing to much information and complicated structure in modern PLC industrial system, this paper sets forth a display method of turning on the basis of traditional display method. According to write control program of PLC and page program of Display-Control Screen, information can be showed by turns in Display-Control Screen. The paper discusses idiographic arithmetic of this display method, and in this way, synthetical Display-Control Screen is applied in PLC Observing and Controlling System Of Gate of Yellow River Sluice successfully.
