dcs和plc的表現(xiàn)的主要差別是在開(kāi)關(guān)量的邏輯解算和模擬量的運(yùn)算上，即使后來(lái)兩者相互有些滲透，但是還是有區(qū)別。80年代以后，plc除邏輯運(yùn)算外，控制回路用的算法功能已經(jīng)大大加強(qiáng)，但 plc用梯形圖編程，模擬量的運(yùn)算在編程時(shí)不太直觀，編程比較麻煩。但在解算邏輯方面，表現(xiàn)出快速的優(yōu)點(diǎn)，在微秒量級(jí)，解算1k邏輯程序不到1毫秒。它把所有的輸入都當(dāng)成開(kāi)關(guān)量來(lái)處理，16位（也有32位的）為一個(gè)模擬量。而dcs把所有輸入都當(dāng)成模擬量，1位就是開(kāi)關(guān)量。解算一個(gè)邏輯是在幾百微秒至幾毫秒量級(jí)。對(duì)于plc解算一個(gè)pid運(yùn)算在幾十毫秒，這與dcs的運(yùn)算時(shí)間不相上下。
