PLC機(jī)型選擇的基本原則是:在功能滿足要求的前提下,選擇最可靠、維護(hù)使用最方便以及性能價(jià)格比最優(yōu)的機(jī)型。通常做法是,在工藝過(guò)程比較固定、環(huán)境條件較好的場(chǎng)合,建議選用整體式結(jié)構(gòu)的PLC;其他情況則最好選用模塊式結(jié)構(gòu)的PLC;對(duì)于開(kāi)關(guān)量控制以及以開(kāi)關(guān)量控制為主、帶少量模擬量控制的工程項(xiàng)目中,一般其控制速度無(wú)須考慮,因此,選用帶A/D轉(zhuǎn)換、D/A轉(zhuǎn)換、加減運(yùn)算、數(shù)據(jù)傳送功能的低檔機(jī)就能滿足要求;而在控制比較復(fù)雜,控制功能要求比較高的工程項(xiàng)目中(如要實(shí)現(xiàn)PID運(yùn)算、閉環(huán)控制、通信聯(lián)網(wǎng)等),可視控制規(guī)模及復(fù)雜程度來(lái)選用中檔或高檔機(jī)(其中高檔機(jī)主要用于大規(guī)模過(guò)程控制、全PLC的分布式控制系統(tǒng)以及整個(gè)工廠的自動(dòng)化等)。根據(jù)不同的應(yīng)用對(duì)象,表1列出了PLC的幾種功能選擇。
? ? PLC與工業(yè)生產(chǎn)過(guò)程的聯(lián)系是通過(guò)I/O接口模塊來(lái)實(shí)現(xiàn)的。PLC有許多I/O接口模塊,包括開(kāi)關(guān)量輸入模塊、開(kāi)關(guān)量輸出模塊、模擬量輸入模塊、模擬量輸出模塊以及其他一些特殊模塊,使用時(shí)應(yīng)根據(jù)它們的特點(diǎn)進(jìn)行選擇。開(kāi)關(guān)量I/O接口可從傳感器和開(kāi)關(guān)(如按鈕、限位開(kāi)關(guān)等)及控制設(shè)備(如指示燈、報(bào)警器、電動(dòng)機(jī)起動(dòng)器等)接收信號(hào)。典型的交流輸入/輸出信號(hào)為24~240V,直流輸入/輸出信號(hào)為5~240V。盡管輸入電路因制造廠家不同而不同,但有些特性是相同的,如用于消除錯(cuò)誤信號(hào)的抖動(dòng)電路等。此外,大多數(shù)輸入電路在高壓電源輸入和接口電路的控制邏輯部分之間都設(shè)有可選的隔離電路。在評(píng)估離散輸出時(shí),應(yīng)考慮熔絲、瞬時(shí)浪涌保護(hù)和電源與邏輯電路間的隔離電路。熔絲電路也許在開(kāi)始時(shí)花費(fèi)較多,但可能比在外部安裝熔絲耗資要少。
