2 三大控制系統(tǒng)之間的差異
2.1 差異
2.1.1 DCS或PLC
PLC系統(tǒng)與DCS系統(tǒng)的結(jié)構(gòu)差異不大，只是在功能的著重點上的不同，DCS著重于閉環(huán)控制及數(shù)據(jù)處理。PLC著重于邏輯控制及開關(guān)量的控制，也可實現(xiàn)模擬量控制。
DCS或PLC系統(tǒng)的關(guān)鍵是通信。也可以說數(shù)據(jù)公路是分散控制系統(tǒng)DCS及PLC的脊柱。由于它的任務是為系統(tǒng)所有部件之間提供通信網(wǎng)絡，因此，數(shù)據(jù)公路自身的設計就決定了總體的靈活性和安全性。數(shù)據(jù)公路的媒體可以是：一對絞線、同軸電纜或光纖電纜。
DCS的特點是：
（1）控制功能強。可實現(xiàn)復雜的控制規(guī)律，如串級、前饋、解耦、自適應、*和非線性控制等。也可實現(xiàn)順序控制。
（2）系統(tǒng)可靠性高。
（3）采用CRT操作站有良好的人機界面。
（4）軟硬件采用模塊化積木式結(jié)構(gòu)。
（5）系統(tǒng)容易開發(fā)。
（6）用組態(tài)軟件，編程簡單，操作方便。
（7）有良好的性價比。
