在 RUN 狀態(tài)下電源中斷后再次供電，S7-400 CPU 通過初始化路徑然后自動(dòng)執(zhí)行熱啟動(dòng)。重新熱啟動(dòng)后，用戶程序在中斷點(diǎn)繼續(xù)運(yùn)行 (定時(shí)器，計(jì)數(shù)器，指示器不被重新設(shè)置，當(dāng)前數(shù)值保存在 DB 塊中)。在斷電前未執(zhí)行的用戶程序被稱為剩余循環(huán)程序。剩余循環(huán)程序同時(shí)包括時(shí)間和報(bào)警控制程序部分。 

· 熱啟動(dòng)中，所有數(shù)據(jù)包括過程映像區(qū)都執(zhí)行它們最后的有效數(shù)值。

· 程序在中斷點(diǎn)繼續(xù)執(zhí)行命令。

· 在當(dāng)前周期完成之前，輸出不會(huì)改變。

· 如果供電中斷，熱啟動(dòng)只可適用于緩沖模式。

原則上來說，如果用戶程序在 STOP 狀態(tài)下沒有改變 (例如裝載一個(gè)修改過的塊) 或者因?yàn)槟承┰蚨恍枰M(jìn)行啟動(dòng) (暖啟動(dòng))，那么，熱啟動(dòng)是允許的。

熱啟動(dòng)的操作命令：

如果相關(guān)參數(shù)已設(shè)定于 CPU 中，并且是如下原因造成 STOP, 那么手動(dòng)熱啟動(dòng)是可行的：

· 模式選擇器從 RUN 轉(zhuǎn)換到 STOP。

· STOP 已被用戶編程，STOP 在調(diào)用 OB 后未被載入。

· STOP 狀態(tài)包含于 PG 或某個(gè)通訊功能。

用戶可以觸發(fā)熱啟動(dòng)：301/0312/STD - ABB - Commander 300 Universal Process Controller Commander 300
