FOXBORO P0973LN 交换机

P0973LN  工业年月机作为中央控制单元，配有组态软件，选用大屏幕实时监视界面，实现各控制点的动态显示、数据修改、故障诊断、自动报警，还可显示查询历史事件记录，系统各主要部件累计运行时间，各装置工艺流程图，各装置结构图等。中央控制单元和下位机PLC之间采用串行通讯方式进行数据交换，通常距离在1000m以内选用485双绞线通讯方式，较常距离可选用光纤通讯，更长距离也可选用无线通讯方式。下位机选用PLC控制，根据控制对象的多少，控制对象的范围，可选用一台或多台PLC进行控制，PLC之间数据交换是利用内部链接寄存器，实现数据交换和共享。由于PLC对现场进实时监控具有很高的可靠性，且编程简单、灵活，因此越来越受到人们重视。
