1、PLC的特點:
現(xiàn)代工業(yè)生產(chǎn)是復(fù)雜多樣的,它們對控制的要求也各不相同。可編程序控制器一經(jīng)出現(xiàn)就受到了廣大工程技術(shù)人員的歡迎。它的主要特點如下:

(1)抗*力強,可靠性高
微機雖然具有很強的功能,但抗*力差,工業(yè)現(xiàn)場的電磁干擾,電源波動,機械振動,溫度和濕度的變化,都可以使一般通用微機不能正常工作。而PLC在電子線路、機械結(jié)構(gòu)以及軟件結(jié)構(gòu)上都吸取生產(chǎn)廠家*積累的工業(yè)控制經(jīng)驗,主要模塊均采用大規(guī)模與超大規(guī)模集成電路,I/0系統(tǒng)設(shè)計有完善的通道保護與信號調(diào)理電路;在結(jié)構(gòu)上對耐熱、防潮、防塵、抗震等都有精確考慮;在硬件上采用隔離、屏蔽、濾波、接地等抗干擾措施;在軟件上采用數(shù)字濾波等抗干擾和故障診斷措施;所有這些使PLC具有較高的抗*力。PLC的平均*時間通常在幾萬小時以上,這是一般微機不能比擬的。
