描述
PLC與DCS的基本結(jié)構(gòu)是一樣的。PLC發(fā)展到今天,已經(jīng)全面移植到計算機系統(tǒng)控制上了,傳統(tǒng)的編程器早就被淘汰。小型應(yīng)用的PLC一般使用觸摸屏,大規(guī)模應(yīng)用的PLC全面使用計算機系統(tǒng)。和DCS一樣,控制器與IO站使用現(xiàn)場總線(一般都是基于RS485或RS232異步串口通訊協(xié)議的總線方式),控制器與計算機之間如果沒有擴展的要求,也就是說只使用一臺計算機的情況下,也會受用這個總線通訊。但如果有不止一臺計算機使用,系統(tǒng)結(jié)構(gòu)就會和DCS一樣,上位機平臺使用以太網(wǎng)結(jié)構(gòu)。這是PLC大型化后和DCS概念模糊的原因之一。
