大多數(shù)模塊式PLC使用底板或機架,其作用是:電氣上,實現(xiàn)各模塊間的使CPU能訪問底板上的所有模塊,機械上,實現(xiàn)各模塊間的連接,使各模塊構成一個整體。
電氣自動化是電子與計算機技術為基礎,實現(xiàn)有關電氣工程的一系列運行、控制、處理、實驗研發(fā)等功能的技術.改革開放以來,我國的工業(yè)得到快速發(fā)展,電氣自動化自然也屬于發(fā)展快速的環(huán)節(jié)之一,然而,各個領域技術的融合入帶給了電氣自動化新的發(fā)展前景,比如嵌入式網絡通信技術的應用,PLCJI技術的融合,給電氣自動化的靈活控制性帶了了顯著的提升,也在各方面取得了取得良好的應用成果.
