大型化PLC發(fā)展方向主要有以下幾個方面：

     ① 功能不斷加強：不僅具有邏輯運算、計數(shù)、定時等基本功能，還具有數(shù)值運算、模擬調節(jié)、監(jiān)控、記錄、顯示、與計算機接口、通信等功能。

         網(wǎng)絡功能是PLC發(fā)展的一個重要特征。各種個人計算機，圖形工作站、小型機等都可以作為PLC的監(jiān)控主機或工作站，這些裝置的結合能夠提供屏幕顯示、數(shù)據(jù)采集、記錄保持、回路面板顯示等功能。大量的PLC聯(lián)網(wǎng)及不同廠家生產(chǎn)的PLC兼容性增加，使得分散控制或集中管理都能輕易地實現(xiàn)。

     ② 應用范圍不斷擴大：不僅能進行一般的邏輯控制，種類齊全的接口模塊還能進行中斷控制、智能控制、過程控制、遠程控制等。

        用于過程控制的PLC往往對存儲器容量及速度要求較高，為此，開發(fā)了高速模擬量輸入模塊，專用獨立的PID控制器，多路轉換器等，使得數(shù)字技術和模擬量技術在可編程序控制器中得到統(tǒng)一。采用軟件、硬件相結合的方法，使得編程和接線都比過去用常規(guī)儀表控制要方便得多。
