熱插拔過程中報(bào)告的故障
使用上述推薦設(shè)備時(shí)，熱插拔可能導(dǎo)致NDCU-12CK
與模塊及其輸入/輸出電路的丟失或添加相關(guān)的預(yù)期故障報(bào)告。這些
應(yīng)以正常方式清除故障。但是，熱插拔rev。J或更高版本
模塊不會(huì)導(dǎo)致配置不匹配錯(cuò)誤，在某些類型的系統(tǒng)中，這些錯(cuò)誤可能會(huì)關(guān)閉關(guān)閉控制器。
熱插拔期間的輸入/輸出模塊數(shù)據(jù)
如上所述，熱插拔時(shí)必須關(guān)閉單獨(dú)的輸入/輸出模塊電源。當(dāng)
模塊已安裝并重新通電，模塊數(shù)據(jù)將快速恢復(fù)正常。對(duì)于
智能輸入/輸出模塊，當(dāng)模塊通過其
通電順序。
微場(chǎng)處理器的熱插拔
可以如上所述移除/插入J版或更高版本的微現(xiàn)場(chǎng)處理器。
然而，請(qǐng)注意，盡管微現(xiàn)場(chǎng)處理器將在重新安裝后開始工作，
必須重新加載MFP的應(yīng)用程序。由微現(xiàn)場(chǎng)處理器控制的輸入/輸出數(shù)據(jù)
在完成之前將不正確。NDCU-12CK數(shù)字量輸入輸出模塊（Micro Field Processor的配置不是
受熱插拔影響）。
Faults Reported During Hot Insertion/Removal
When using the recommended equipment listed above, Hot Insertion/Removal may cause the
expected fault reports related to the loss of or addition of the module and its I/O circuits. These
faults should be cleared in the normal manner. However, Hot Insertion/Removal of a rev. J or later
module will NOT cause Configuration Mismatch errors that in some types of systems can shut
down the controller.
I/O Module Data During Hot Insertion/Removal
As mentioned, separate I/O module power must be turned off for Hot Insertion/Removal. When the
module is installed and power is reapplied, module data will quickly return to normal. For
intelligent I/O modules, there may be a delay of a few seconds while the module goes through its
powerup sequence.
Hot Insertion/Removal for a Micro Field Processor
A Micro Field Processor that is revision J or later may be removed/inserted as described above.
Note, however, that although the Micro Field Processor will start functioning upon reinstallation,
the MFP's application program must be reloaded. I/O data controlled by the Micro Field Processor
will be incorrect until that has been done. (The configuration of the Micro Field Processor is not
affected by Hot Insertion/Removal).
