While the PLC is always in a long time in the field of industrial automation, it controls the main battlefield for a wide range of automation equipment to provide a very reliable control applications .With the rapid development of electronic business, PLC has been able to adapt in various of fields and different customer requirements. This article is for the two-tank water system, using Siemens S7-300 series PLC programming software in the PID control function blocks for control algorithms, programming , hardware configuration, the AE2000A experimental device and WINCC configuration under the circumstances achieve tank level control. It realizes the P, I, D parameter setting of the three, as well as real-time monitoring of the object and running. 【KEYWORDS】Two-tank ，Siemens PLC，PID Control ，WinCC 目　录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc261691743 摘　要  PAGEREF _Toc261691743 \h II  HYPERLINK \l _Toc261691744 Abstract  PAGEREF _Toc261691744 \h III  HYPERLINK \l _Toc261691745 目　录  PAGEREF _Toc261691745 \h IV  HYPERLINK \l _Toc261691746 第一章 序言  PAGEREF _Toc261691746 \h 1  HYPERLINK \l _Toc261691747 1.1 选题的背景与趋势  PAGEREF _Toc261691747 \h 1  HYPERLINK \l _Toc261691748 1.2选题的意义  PAGEREF _Toc261691748 \h 2  HYPERLINK \l _Toc261691749 第二章 可编程PLC技术  PAGEREF _Toc261691749 \h 3  HYPERLINK \l _Toc261691750 2.1 PLC的基本概念  PAGE
