PLC is the product of the bination of microelectronic technology and automatic control technology, and it can be influenced by puter technology and munication technology. Recent years, as the level of the industry automation increased in our country, PLC has been widely used in more and more fields. Siemens PLC of the s7300 series has been the favor of many industries, with the characters of pacted structure, strong extensible ability, and high function/price ratio. This design is going to fulfill a liquid level control system, which is stable, safe, and affordable, using s7300 as the controller. The core is CPU313C2DP of S7300 series and the auxiliary parts contain a solenoid valve, a pressure transmitter, a motor, PC, a separatedtype tank and so on. In the design, software system and hardware system can be designed pletely.During the designing process, first of all, hardwires are chosen and designed. Second, module programming can be done to get normalized data and Position Control. Third, HMI can be finished using King software, which is used to control the liquid level, adjust the top and bottom limitation parameters online, monitor measured value of the liquid level, and meet the technical needs of controlling liquid level.Key Word: S7300；Kingview；Liquid level目 錄1 引言 1 1 PLC及過(guò)程控制技術(shù)的概述及發(fā)展 1 本課題研究的內(nèi)容與目的 42 液位控制系統(tǒng)硬件設(shè)計(jì) 5 液位控制系統(tǒng)的系統(tǒng)設(shè)計(jì) 5 PLC的選型 5 CPU型號(hào)的選擇 6 模擬量模塊（SM）的確定 6 電源模塊的選用 8 8 9 93 液位控制系統(tǒng)的軟件設(shè)計(jì) 11 11 11 PLC程序設(shè)計(jì) 12 固定頻率的設(shè)定 12 PLC控制要求和策略 12 PLC程序控制流程 12 STEP 7編程過(guò)程 13 16 “組態(tài)王”軟件界面 17 上位機(jī)組態(tài)畫(huà)面
