热插拔过程中报告的故障
使用上述推荐设备时,热插拔可能导致NDCU-12CK
与模块及其输入/输出电路的丢失或添加相关的预期故障报告。这些
应以正常方式清除故障。但是,热插拔rev。J或更高版本
模块不会导致配置不匹配错误,在某些类型的系统中,这些错误可能会关闭关闭控制器。

热插拔期间的输入/输出模块数据
如上所述,热插拔时必须关闭单独的输入/输出模块电源。当
模块已安装并重新通电,模块数据将快速恢复正常。对于
智能输入/输出模块,当模块通过其
通电顺序。
微场处理器的热插拔
可以如上所述移除/插入J版或更高版本的微现场处理器。
然而,请注意,尽管微现场处理器将在重新安装后开始工作,
必须重新加载MFP的应用程序。由微现场处理器控制的输入/输出数据
在完成之前将不正确。NDCU-12CK数字量输入输出模块(Micro Field Processor的配置不是
受热插拔影响)。
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).
