中文摘要：介绍了由多台可编程控制器（ＰＬＣ）作为下位机与上位微机构成的远程自动监测系统。利用下位机与上位机的串行通讯，使所有的数据汇集到上位微机集中处理，并打印成报表。下位机的数字显示用传感器的变送器完成，显示汉字及数据。本系统也可扩展Ａ／Ｄ、Ｄ／Ａ。

外文摘要：This article introduces the long range monitoring system formed of many PLC as supper place machines amd lower place machinces.By seres communication of upper place machines and lower place machines,all the datum converging in the upper place machine are treated with together and printed into report forms.The data display of lower place machines is completed with the second meter of sensons and it displays chinese character and data.This system can also extend A/D and D/A,parallel connectors,etc,and can be used in data collection and control of other suitable principle and subordinate series machine systems.
