描述

有人預(yù)測DCS將被FCS所取代，在我看來，DCS是由現(xiàn)場儀表+雙向I/O通訊+現(xiàn)場信號采集器+控制器+控制網(wǎng)絡(luò)+操作站組成。FCS的發(fā)展目標是替代（現(xiàn)場儀表+雙向I/O通訊+現(xiàn)場信號采集器+控制器+控制網(wǎng)絡(luò)），但是由于現(xiàn)場總線技術(shù)的可靠性和可用性以及安全性都未充分解決，完全將控制功能下放到現(xiàn)場總線儀表中（變送器和定位器），目前技術(shù)上還不成熟，現(xiàn)場總線儀表控制功能和DCS控制器控制相互備用的情況還將長期存在。甚至現(xiàn)場總線儀表僅完成雙向數(shù)字通訊，其控制功能仍就在DCS的控制器中這種現(xiàn)象也會長期存在下去。
