開(kāi)關(guān)量:按電壓水平分,有220VAC、110VAC、24VDC,按隔離方式分,有繼電器隔離和晶體管隔離。
模擬量:按信號(hào)類(lèi)型分,有電流型(4-20mA,0-20mA)、電壓型(0-10V,0-5V,-10-10V)等,按精度分,有12bit,14bit,16bit等。
Meter VM600 MPC4 200-510-071-113
除了上述通用IO外,還有特殊IO模塊,如熱電阻、熱電偶、脈沖等模塊。
按I/O點(diǎn)數(shù)確定模塊規(guī)格及數(shù)量,I/O模塊可多可少,但其*大數(shù)受CPU所能管理的基本配置的能力,即受*大的底板或機(jī)架槽數(shù)限制?! ?br />
五、電源模塊
PLC電源用于為PLC各模塊的集成電路提供工作電源。同時(shí),有的還為輸入電路提供24V的工作電源。電源輸入類(lèi)型有:交流電源(220VAC或110VAC),直流電源(常用的為24VDC)?! ?br />
六、底板或機(jī)架
大多數(shù)模塊式PLC使用底板或機(jī)架,其作用是:電氣上,實(shí)現(xiàn)各模塊間的聯(lián)系,使CPU能訪問(wèn)底板上的所有模塊,機(jī)械上,實(shí)現(xiàn)各模塊間的連接,使各模塊構(gòu)成一個(gè)整體?! ?br />
七、PLC系統(tǒng)的其它設(shè)備
1、編程設(shè)備:編程器是PLC開(kāi)發(fā)應(yīng)用、監(jiān)測(cè)運(yùn)行、檢查維護(hù)不可缺少的器件,用于編程、對(duì)系統(tǒng)作一些設(shè)定、監(jiān)控PLC及PLC所控制的系統(tǒng)的工作狀況,但它不直接參與現(xiàn)場(chǎng)控制運(yùn)行。小編程器PLC一般有手持型編程器,目前一般由計(jì)算機(jī)(運(yùn)行編程軟件)充當(dāng)編程器。
2、人機(jī)界面:*簡(jiǎn)單的人機(jī)界面是指示燈和按鈕,目前液晶屏(或觸摸屏)式的一體式操作員終端應(yīng)用越來(lái)越廣泛,由計(jì)算機(jī)(運(yùn)行組態(tài)軟件)充當(dāng)人機(jī)界面非常普及。
3、輸入輸出設(shè)備:用于性地存儲(chǔ)用戶數(shù)據(jù),如EPROM、EEPROM寫(xiě)入器、條碼閱讀器,輸入模擬量的電位器,打印機(jī)等。
八、PLC的通信聯(lián)網(wǎng)
依靠先進(jìn)的工業(yè)網(wǎng)絡(luò)技術(shù)可以迅速有效地收集、傳送生產(chǎn)和管理數(shù)據(jù)。因此,網(wǎng)絡(luò)在自動(dòng)化系統(tǒng)集成工程中的重要性越來(lái)越顯著,甚至有人提出"網(wǎng)絡(luò)就是控制器"的觀點(diǎn)說(shuō)法。
