1756-IH16I/ABPLC智能制造

从上图中可看出按照结构划分为：过程控制级、操作维护级和管理层级。过程控制级主要由过程控制器、I/O组件和现场仪表组成，是系统控制功能的主要现场实施部分。操作维护级包括：操作员站，工程师站，以及数据维护站，完成系统的操作，组态，以及数据的存储。管理层级主要是指工厂管理信息系统(MIS系统)，企业资源计划即ERP(Enterprise Resource Planning)，作为DCS更高层次的应用。
目前常见的DCS有哪些？
国外：霍尼韦尔EPKS，西门子PCS，艾默生Deltav和Ovation，横河CENTUM，ABB的AC800F等等；国内：和利时，浙大中控，上海新华，南京科远，国电智深，杭州优稳等等。
下面以霍尼韦尔PKS的C300介绍过程控制级
