技術基本原理 可編程控制器是計算機家族中的一員。對于整個中心的網(wǎng)絡通信和網(wǎng)絡化管理本文將在第四、第五章作初步的敘述和探討。而本文討論的是 PLC 在實際工業(yè)控制系統(tǒng)的應用。它具有功能強大、使用可靠、維修簡單等許多優(yōu)點，并且在很多地方已逐步取代了繼電器電路的邏輯控制。本文僅通過某臺設備電氣控制系統(tǒng)的具體改造來作為重點展開敘述。s work limited pany of JiangNan is because of the industrial structure that variety that development, decision establish a stalk to process the center is on originally possessed of the foundation that the machine manufacturing the cent the factory with the whole stalk process the center is at gradually developments with in the ameliorative process, the many design still did not put into text only passes the some set equipments the electricity control the systems of in a specific way reform to be used as the point to launch the work correspondence of whole center manages with the work this text will make the first step39。而對于傳統(tǒng)的繼電器電路來說，它難以實現(xiàn)復雜邏輯功能的和數(shù)字式控制，而且要實現(xiàn)一定規(guī)模的邏輯控制功能不僅設計繁瑣，難以實現(xiàn)升級，而且易發(fā)故障，維修復雜，現(xiàn)在已被大中型設備的控制系統(tǒng)所拋棄。 的體系結(jié)構(gòu)PLC 實質(zhì)上是一種被專用于工業(yè)控制的計算機，其硬件結(jié)構(gòu)和微機是基本一致的。并將邏輯或算術運算等結(jié)果送入 I/O 映象區(qū)或數(shù)據(jù)寄存器內(nèi)。PLC 的軟件分為兩部分: 系統(tǒng)軟件和應用軟件。A. 系統(tǒng)程序存儲區(qū)在系統(tǒng)程序存儲區(qū)中存放著相當于計算機操作系統(tǒng)的系統(tǒng)程序。B. 系統(tǒng) RAM 存儲區(qū)系統(tǒng) RAM 存儲區(qū)包括 I/O 映象區(qū)以及各類軟設備（列如：邏輯線圈、數(shù)據(jù)寄存器、計時器、計數(shù)器、變址寄存器、累加器等）存儲區(qū)。因此，整個 I/O 映象區(qū)可看作由開關量的 I/O 映象區(qū)和模擬量的 I/O 映象區(qū)
