描述

1．電源模塊的選擇

電源模塊選擇僅對于模塊式結(jié)構(gòu)的PLC而言，對于整體式PLC不存在電源的選擇。

電源模塊的選擇主要考慮電源輸出額定電流和電源輸入電壓。電源模塊的輸出額定電流必須大于CPU模塊、I／O模塊和其它特殊模塊等消耗電流的總和，同時還應(yīng)考慮今后I／O模塊的擴展等因素；電源輸入電壓一般根據(jù)現(xiàn)場的實際需要而定。

2．編程器的選擇

對于小型控制系統(tǒng)或不需要在線編程的系統(tǒng)，一般選用價格便宜的簡易編程器。對于由中、高檔PLC構(gòu)成的復(fù)雜系統(tǒng)或需要在線編程的PLC系統(tǒng)，可以選配功能強、編程方便的智能編程器，但智能編程器價格較貴。如果有現(xiàn)成的個人計算機，也可以選用PLC的編程軟件，在個人計算機上實現(xiàn)編程器的功能。

3．寫入器的選擇

為了防止由于干擾或鋰電池電壓不足等原因破壞RAM中的用戶程序，可選用EPROM寫入器，通過它將用戶程序固化在EPROM中。有些PLC或其編程器本身就具有EPROM寫入的功能。
