包括和應(yīng)用。
（1）：
ABB Master Piece200單元是一高性能32位微處理器。存儲(chǔ)在EPROM模塊中，包括一個(gè)實(shí)時(shí)操作和一個(gè)ABB Master Piece語言（AMPL）執(zhí)行器。
（2）應(yīng)用
應(yīng)用存儲(chǔ)在帶后備電池的RWM（讀/寫存儲(chǔ)器）中，用ABB Master Piece語言（AMPL）編制，實(shí)現(xiàn)了結(jié)構(gòu)化程序設(shè)計(jì)。工業(yè)控制程序往往功能繁多該語言根據(jù)工業(yè)控制要求，將編程元素設(shè)計(jì)成一個(gè)個(gè)圖形功能塊，稱為PC元素。PC元素內(nèi)有三種結(jié)構(gòu)類元素GM、CONTRM和FUNCM，GM是程序結(jié)構(gòu)的高層，旨在完成一個(gè)完整的控制功能，一個(gè)GM下允許一個(gè)或幾個(gè)CONTRM，而一個(gè)CONTRM下又可包含一個(gè)或幾個(gè)FUNCM，從而使整個(gè)程序結(jié)構(gòu)呈階梯狀，實(shí)現(xiàn)了結(jié)構(gòu)化設(shè)計(jì)。
另外，在CPU內(nèi)還有一個(gè)實(shí)時(shí)數(shù)據(jù)庫(kù)，它的作用是存儲(chǔ)數(shù)據(jù)和在程序間傳遞數(shù)據(jù)。數(shù)據(jù)庫(kù)內(nèi)的元素稱為DB元素，這些元素包括站所使用的的I／O模板和及程序中產(chǎn)生的其它數(shù)據(jù)信息。

(2)向大容量，高速度方向發(fā)展
大型PLC采用多微處理器，有的采用32位微處理器，可同時(shí)進(jìn)行多任務(wù)操作，處理速度，特別是增強(qiáng)了控制和數(shù)據(jù)處理的功能。另外，存儲(chǔ)容量大大。
(3)與計(jì)算機(jī)聯(lián)系密切
從功能上看，PLC不僅能完成邏輯運(yùn)算，且計(jì)算機(jī)的復(fù)雜運(yùn)算功能在PLC中也進(jìn)一步利用，從結(jié)構(gòu)上看，計(jì)算機(jī)的硬件和技術(shù)越來越多地應(yīng)用到PLC；從語言上看，PLC己不再是單純用梯形圖語言，而且可用多種語言編程，如類似計(jì)算機(jī)匯編語言的語句表，甚至可直接由計(jì)算機(jī)語言編程；在通訊方面，PLC與計(jì)算機(jī)可直接相連并進(jìn)行信息傳遞。
(4)發(fā)展多樣化
可編程序控制器發(fā)展的多樣化體現(xiàn)在3個(gè)方面：產(chǎn)品類型、編程語言和應(yīng)用領(lǐng)域。
(5)模塊化
PLC的擴(kuò)展模塊發(fā)展迅速。功能明確化、專用化的復(fù)雜功能由專門模塊來完成。主機(jī)僅僅通過通訊設(shè)備向模塊發(fā)布命令和狀態(tài)，這使得PLC的功能進(jìn)一步增強(qiáng)，控制設(shè)計(jì)進(jìn)一步簡(jiǎn)化。
(6)網(wǎng)絡(luò)與通訊能力增強(qiáng)
計(jì)算機(jī)與PLC之間以及各個(gè)PLC之間的聯(lián)網(wǎng)和通訊的能力不斷增強(qiáng)，使用工業(yè)網(wǎng)絡(luò)可以有效地節(jié)省資源、成本、可靠性和靈活性，致使網(wǎng)絡(luò)的應(yīng)用有普遍化的趨勢(shì)。
