摘要：通過介紹泵站自動化在工程應用當中的一個實例，指出設計人員容易忽略的問題：軟件開發使用以太網發布技術，相應的PLC選型也要配置以太網接口，否則很難保證遠程監控系統執行指令的效率。

Abstract： By introducing the applied engineering sample in the field of the pumping station automatization, this paper indicates that the design engineer often ignore the problem; if the software programming is based on Ethernet, then the corresponding PLC type will configure the Ethernet, then the corresponding PLC type will configure the Ethernet interface, otherwise it is very difficult that the long-distance monitoring system effectively execute the instructions.
