6ES7390-1AJ30-0AA0現(xiàn)場自動控制系統(tǒng)分為兩級：過程控制級和設(shè)備控制級。過程控制級負(fù)責(zé)生產(chǎn)管理和設(shè)備運(yùn)行過程監(jiān)控，設(shè)備控制級對液壓站、變頻器、操作的對象進(jìn)行控制。高線廠的精整和加熱爐自控系統(tǒng)都是由馬鋼設(shè)計院設(shè)計的，現(xiàn)在以精整集卷筒為例來分析DP網(wǎng)的組成。

由一臺s7—4OO PLC和一臺工控機(jī)通過高速以太網(wǎng)構(gòu)成本系統(tǒng)的過程控制級，PLC下設(shè)若干ET200M遠(yuǎn)程I／O從站，它們之間通過PROFIBUS—DP現(xiàn)場總線網(wǎng)絡(luò)進(jìn)行通信，構(gòu)成本系統(tǒng)的設(shè)備控制級。圖1是集卷網(wǎng)絡(luò)配置簡圖的一部分，用以解釋其工作原理。
