1X00416H01?CPU及其控制電路，系統(tǒng)程序存儲(chǔ)器

獨(dú)立型PLC有如下特點(diǎn)：

1）獨(dú)立型PLC具有如下基本的功能結(jié)構(gòu)：CPU及其控制電路，系統(tǒng)程序存儲(chǔ)器，用戶程序存儲(chǔ)器、輸入／輸出接口電路、與編程機(jī)等外部設(shè)備通信的接口和電源等

2）獨(dú)立型PLC一般采用積木式模塊化結(jié)構(gòu)或籠式插板式結(jié)構(gòu)，各功能電路多做成獨(dú)立的模塊或印刷電路插板，具有安裝方便，功能易于擴(kuò)展和變更等優(yōu)點(diǎn)。例如，可采用通信模塊與外部輸入輸出設(shè)備、編程設(shè)備、上位機(jī)、下位機(jī)等進(jìn)行數(shù)據(jù)交換；采用D／A模塊可以對(duì)外部伺服裝置直接進(jìn)行控制；采用計(jì)數(shù)模塊可以對(duì)加工工件數(shù)量、刀具使用次數(shù)、回轉(zhuǎn)體回轉(zhuǎn)分度數(shù)等進(jìn)行檢測(cè)和控制，采用定位模塊可以直接對(duì)諸如刀庫(kù)、轉(zhuǎn)臺(tái)、直線運(yùn)動(dòng)軸等機(jī)械運(yùn)動(dòng)部件或裝置進(jìn)行控制。

3）獨(dú)立型PLC的輸入、輸出點(diǎn)數(shù)可以通過(guò)I／O模塊或插板的增減靈活配置。有的獨(dú)立型PLC還可通過(guò)多個(gè)遠(yuǎn)程終端連接器構(gòu)成有大量輸入、輸出點(diǎn)的網(wǎng)絡(luò)，以實(shí)現(xiàn)大范圍的集中控制。

在獨(dú)立型PLC中，那些專(zhuān)為用于FMS、FA而開(kāi)發(fā)的獨(dú)立型PLC具有強(qiáng)大的數(shù)據(jù)處理、通信和診斷功能，主要用作“單元控制器”，是現(xiàn)代自動(dòng)化生產(chǎn)制造系統(tǒng)重要的控制裝置。獨(dú)立型PLC也用于單機(jī)控制。

Independent PLC has the following characteristics:

1) Independent PLC has the following basic functional structure: CPU and its control circuit, system program memory, user program memory, input/output interface circuit, interface and power supply for communication with external devices such as programming machines (see Figure 5-2).

2) The independent PLC generally adopts the modular structure of building blocks or cage plug plate structure, and the functional circuits are mostly made into independent modules or printed circuit boards, which have the advantages of easy installation, easy expansion and change of functions. For example, the communication module can be used to exchange data with external input and output devices, programming devices, upper computers, lower computers, etc. The D/A module can be used to directly control the external servo device. The counting module can be used to detect and control the number of machining workpieces, the number of tool use, the number of rotation degrees of the rotary body, etc. The positioning module can be used to directly control the mechanical moving parts or devices such as the tool library, the rotary table, and the linear movement shaft.

3) The input and output points of independent PLC can be flexibly configured through the increase or decrease of I/O modules or plugboards. Some independent PLC can also constitute a network with a large number of input and output points through a number of remote terminal connectors to achieve a wide range of centralized control.

In the independent PLC, those designed for FMS, FA and the development of independent PLC has powerful data processing, communication and diagnostic functions, mainly used as a “unit controller”, is an important control device for modern automated production and manufacturing systems. Independent PLC is also used for single machine control.
