描述
可編程控制器是將繼電器控制的概念和設(shè)計思想與計算機技術(shù)及微電子技術(shù)相結(jié)合而形成的專門從事邏輯控制的微機系統(tǒng)。在PC系統(tǒng)應(yīng)用中,梯形圖的設(shè)計往往是最主要的問題。梯形圖不但沿用和發(fā)展了電氣控制技術(shù),而且其功能和控制指令已遠(yuǎn)遠(yuǎn)超過電氣控制范疇。它不僅可實現(xiàn)邏輯運算,還具有算術(shù)運算、數(shù)據(jù)處理、聯(lián)網(wǎng)通信等功能,是具有工業(yè)控制指令的微機系統(tǒng)。由于梯形圖的設(shè)計是計算機程序設(shè)計與電氣控制設(shè)計思想結(jié)合的產(chǎn)物,因此,在設(shè)計方法上與計算機程序設(shè)計和電氣控制設(shè)計既有著相同點,也有著不同點。
替代設(shè)計法
所謂替代設(shè)計法,就是用PC機的程序,替代原有的繼電器邏輯控制電路。它的基本思想是:將原有電氣控制系統(tǒng)輸入信號及輸出信號做為PC的I/O點,原來由繼電器—接觸器硬件完成的邏輯控制功能由PC機的軟件—梯形圖及程序替代完成
