IC694ALG392數控模塊
單獨命名并獨立地完成功能的程序語句的集合(即程序代碼和數據結構的集合體)。它具有兩個基本的特征:外部特征和內部特征。外部特征是指模塊跟外部環境聯系的接口(即其他模塊或程序調用該模塊的方式,包括有輸入輸出參數、引用的全局變量)和模塊的功能;內部特征是指模塊的內部環境具有的特點(即該模塊的局部數據和程序代碼)。

輸入電壓范圍:即UPS允許市電電壓的變化范圍,因為當地的電壓波動情況直接影響UPS的運行,特別是有些地區電網比較惡劣,白天和晚上的電壓相差很大。如果UPS 要24小時工作,在如此大的變化范圍里,UPS能否工作至關重要。如不能工作,只有轉電池,這樣一則電池并沒有用于真正的斷電,二則頻繁轉電池會影響電池的壽命。如果該UPS的轉電池裝置為繼電器,則對繼電器的損壞特別嚴重,大大增加了UPS的故障率。
