4．增強外部故障的檢測與處理能力

     根據統計資料表明：在PLC控制系統的故障中，CPU占5%，I/O接口占15%，輸入設備占45%，輸出設備占30%，線路占5%。前二項共20%故障屬于PLC的內部故障，它可通過PLC本身的軟、硬件實現檢測、處理；而其余80%的故障屬于PLC的外部故障。因此，PLC生產廠家都致力于研制、發展用于檢測外部故障的智能模塊，進一步提高系統的可靠性。

    5．編程語言多樣化

  在PLC系統結構不斷發展的同時，PLC的編程語言也越來越豐富，功能也不斷提高。除了大多數PLC使用的梯形圖語言外，為了適應各種控制要求，出現了面向順序控制的步進編程語言、面向過程控制的流程圖語言、與計算機兼容的高級語言（BASIC、C語言等）等。多種編程語言的并存、互補與發展是PLC進步的一種趨勢。
