PLC向開放性發展
早期的PLC缺點之一是它的軟、硬件體系結構是封閉而不是開放的，如專用總線、通訊網絡及協議、I/O模塊更互不通用，甚至連機架、電源模板亦各不相同，編程語言之一的梯形圖名稱雖一致，但組態、尋址、語言結構均不一致，因此，幾乎各個公司的PLC均互不兼容。目前，PLC在開放性方面已有實質性突破。十多年前PLC被攻破的一個重要方面就是它的專有性，現在情況有了極大改觀，不少大型PLC廠商在PLC系統結構上采用了各種產業標準，如IEC61131-3、IEEE802.3以太網、TCP/IP、UDP/IP等。例如，AEGSchneider團體已開發以PLC機為基礎，在Windows平臺下，符合IEC61131-3國際標準的全新一體系結構的PLC實現高度分散控制，開放度高。高度分散控制是一種全新的產業控制結構，不但控制功能分散化，而且網絡也分散化，所謂高度分散化控制，就是控制算法常駐在該控制功能的節點上，而不是常駐在PLC上或PC上，凡掛在網絡節點上的設備，均處于同等的位置，將“智能”擴展到控制系統的各個環節，從傳感器、變送器到I/O模塊，乃至執行器，無處不采用微處理芯片，因而產生了智能分散系統（SDS）。

為了使PLC更具開放性和執行多任務，在一個PLC系統中同時裝幾個CPU模塊，每個CPU模塊都執行某一種任務。例如三菱電機公司的小Q系列PLC可以在一個機架上插4個CPU模塊，富士電機的MICREX-ST系列最多可在一個機架上插6個CPU模塊，這些CPU模塊可以進行專門的邏輯控制、順序控制、運動控制和過程控制。這些都是在Windows環境下執行PC機任務的模塊，組成混合式的控制系統。
近幾年，眾多PLC廠商都開發了自己的模塊型I/O或端子型I/O，而通訊總線都符合IEC61131-3標準，這極大的增強了PLC的開放性。
創建開放的網絡環境后，推出了能掛100M的高速以太網的WEB服務器模塊，三菱電機公司小Q系列的QJ71WS96，橫河電機FA-M3系列的F3WBM1-0T-S0；模塊內的軟件捆綁了目前常用的TCP/IP、UDP/IP等傳輸層和網絡層規約，以及HTTP、FTP、SMTP、POP3等應用層規約，使PLC可直接進進因特網，成為不折不扣的WEB的PLC。
3、PLC的體積小型化，運算速度高速化
PLC小型化的好處是節省空間、降低本錢、安裝靈活。目前一些大型PLC，其外形尺寸比他們前一代的同類產品的安裝空間要小50%左右。
近幾年，很多PLC廠商推出了超小型PLC，用于單機自動化或組成分布式控制系統。西門子公司的超小型PLC稱通用邏輯模塊LOGO！，它采用整體式結構，集成了控制功能、實時時鐘和操縱顯示單元，可用面板上的小型液晶顯示屏和6個鍵來編程。LOGO！超小型PLC使用功能模塊圖FBD編程語言，有在PC上運行的Windows98/NT編程軟件。
三菱電機的超小型PLC叫簡單應用控制器，簡稱α并有AL-PCS/win-C型VLS軟件，是強有力且界面友好的編程工具。松下電工的超小型PLC叫可選模式控制器。德國金鐘—默勒公司（MOELLER）的超小型PLC稱控制繼電器，簡稱easy。
運算速度高速化是PLC技術發展的重要特點，在硬件上，PLC的CPU模塊采用32位的RISC芯片，使PLC的運算速度大為進步，一條基本指令的運算速度達到數十個納秒（ns）。三菱電機公司的ANA系列PLC最早使用32位的CPU模塊，當今它的Q02H系列PLC的CPU模塊也用了32位的RISC芯片，基本指令的執行時間為34ns；富士電機MICREX-SX系列PLC的CPU模塊由于采用了32位RISC芯片后，其一條基本指令的運算時間為20ns。
