进入 90年代 ,ＤＣＳ系统的应用渐渐走向成熟。由于它可以满足连续过程、离散过程和批量过程等各种工业控制要求 ,至 90年代中期 ,在大中型空分设备中ＤＣＳ已完全取代了常规仪表。这个时期ＤＣＳ的特点 (以ＴＤＣ30 0 0为代表 ) ,是系统运行稳定可靠、操作安全、组态过程灵活
Into the 90’s, DCS system gradually mature. Because it can satisfy various industrial control requirements such as continuous process, discrete process and batch process, by the mid-1990s, DCS had completely replaced conventional instruments in large and medium-sized air separation plants. DCS characteristics of this period (represented by TDC30 0 0), the system is stable and reliable, safe operation, flexible configuration process
