摘要:本文介紹了S7-200 小型PLC的工作原理及在彩燈控制中的應用,設計了一種基于PLC的循環(huán)彩燈的亮滅、閃爍及流動方向的PLC控制程序,經(jīng)模擬仿真,達到預期的控制要求。 關鍵字:PLC;循環(huán)彩燈;梯形圖程序
Abstract:This paper introduces the working principle of S7-200 PLC and its application in lantern’s controlling , a corresponding program had been designed based on PLC to control the lanterns’ turning on and turning off, the flash and the flow direction had also been accomplished, the desired control requirements had achieved successfully after simulation. Key words: PLC; lanterns; ladder diagram program
采用PLC來控制彩燈循環(huán),提高了系統(tǒng)運行的可靠性,其梯形圖程序簡單直觀,利用PLC的定時功能、計數(shù)功能、步進功能,可靈活地編寫、增減和修改程序。PLC具有很強的自診斷功能。迅速方便的檢查判斷出故障,縮減了檢修時間,不需要很多配套的外圍設備和大量復雜的接線。大大縮減了設計和施工周期。 |
