AB 1746-P2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。
AB 1746-P2
1工作速度
工作速度是指PLC的CPU執行指令的速度及對急需處理的輸入信號的響應速度。工作速度是PLC工作的基礎。速度高了，才可能通過運行程序實現控制，才可能不斷擴大控制規模，才可能發揮PLC的多種多樣的作用。
PLC的指令是很多的。不同的PLC。指令的條數也不同。少的幾十條，多的幾百條。指令不同，執行的時間也不同。但各種PLC總有一些基本指令，而且各種的PLC都有這些基本指令，故常以執行一條基本指令的時間來衡量這個速度。這個時間當然越短越好，已從微秒級縮短到零點微秒級。并隨著微處理器技術的進步，這個時間還在縮短。
