【正文】 data curve etc., produced a business, clique extensive adoption for industrial automatic control bringing excellent supervision and supervision function, so in the capacity. This design is mainly is according to configuration king and PLC liquid potential control system, and provide an excellent control scheme for the liquid potential control system as for control characteristics that bine an configuration king39。 組態(tài)王是工業(yè)控制系統(tǒng)中常用的監(jiān)控軟件，其集動(dòng)畫(huà)顯示、流程控制、數(shù)據(jù)采集、設(shè)備控制與輸出、網(wǎng)絡(luò)數(shù)據(jù)傳輸、工程報(bào)表以及數(shù)據(jù)曲線(xiàn)等諸多功能，在生產(chǎn)之中為工業(yè)自動(dòng)控制帶來(lái)優(yōu)秀的管理與監(jiān)控功能，所以被生產(chǎn)企業(yè)、集團(tuán)廣泛采 用。I 摘 要 自可編程邏輯控制器問(wèn)世以來(lái)，已經(jīng)經(jīng)過(guò)四十余年的發(fā)展，成為當(dāng)今增長(zhǎng)速度最快的工業(yè)控制器，在工業(yè)控制領(lǐng)域中應(yīng)用十分廣泛。 本設(shè)計(jì)是主要是基于組態(tài)王與 PLC 的液位控制系統(tǒng)，并結(jié)合變頻器的控制特點(diǎn)，為液位控制系統(tǒng)提供一個(gè)優(yōu)秀的控制方案。s supervision supervisions, the S7200 series PLC logic controller higher reliability, control, the liquid potential of the dynamic state control characteristic and adoption PID controller assemble of inverter control system, can bring the good dynamic state the control performance.
