1)控制規(guī)模不斷擴(kuò)大,單臺(tái)PLC可控制成千乃*萬個(gè)點(diǎn),多臺(tái)PLC進(jìn)行同位鏈接可控制數(shù)萬個(gè)點(diǎn)。
2)指令系統(tǒng)功能增強(qiáng),能進(jìn)行邏輯運(yùn)算、計(jì)時(shí)、計(jì)數(shù)、算術(shù)運(yùn)算、PID運(yùn)算、數(shù)制轉(zhuǎn)換、ASCⅡ碼處理。高檔PLC還能處理中斷、調(diào)用子程序等。使得PLC能夠?qū)崿F(xiàn)邏輯控制、模擬量控制、數(shù)值控制和其他過程監(jiān)控,以至在某些方面可以取代小型計(jì)算機(jī)控制。
3)處理速度提高,每個(gè)點(diǎn)的平均處理時(shí)間從10μs左右提高到1μs以內(nèi)。
4)編程容量增大,從幾K字節(jié)增大到幾十K,甚*百K字節(jié)。
5)編程語言多樣化,大多數(shù)使用梯形圖語言和語句表語言,有的還可使用流程圖語言或高級(jí)語言。
6)增加通信與聯(lián)網(wǎng)功能,多臺(tái)PLC之間能互相通信,互相交換數(shù)據(jù),PLC還可以與上位計(jì)算機(jī)通信,接受計(jì)算機(jī)的命令,并將執(zhí)行結(jié)果告訴計(jì)算機(jī)。通信接口多采用RS-422/RS-232C等標(biāo)準(zhǔn)接口,以實(shí)現(xiàn)多級(jí)集散控制。
