NDCU-12C数字量输入输出模块,NDCU-12C卡件
总线接口单元NDCU-12C 或更高版本支持热插拔
输入/输出站中的模块数量。
热插入/移除意味着可以在I/O站通电时移除和更换模块
在不影响BIU或输入/输出站中的其他模块的情况下应用。独立输入/输出模块
必须关闭插入或卸下模块的电源。
热插拔需要使用特定模块和输入/输出接线板：
具有目录号后缀J或以上的输入/输出模块。这些模块有一个
与下面列出的输入/输出端子上的相应对齐选项卡相匹配的对齐选项卡。
请注意，带有此选项卡的模块也可以安装在没有NDCU-12C数字量输入输出模块
具有匹配的对齐卡舌。但是，在这种情况下不支持热插入/移除
安装
输入/输出接线板IC670CHS101、102或103。这些输入/输出接线板具有突出的
对齐卡舌设计用于方便热插入/移除模块。以下模块
这些接线板上不能安装J版之前的产品。
输入/输出接线板IC670CHS001、002和003没有对齐卡舌，不支持
模块的热插拔。使用这些接线板，输入/输出站电源应
安装或卸下模块时关闭。
在同一输入/输出中混合IC670CHS10x接线板和IC670CHS00x接线板
不建议使用站点。
Bus Interface Units IC670GBI002(F) and IC670GBI102A or later support Hot Insertion/Removal
of modules in the I/O Station.
Hot Insertion/Removal means that modules can be removed and replaced while I/O Station power
is applied without affecting the BIU or other modules in the I/O Station. Separate I/O module
power must be switched off to the module being inserted or removed.
Hot Insertion/Removal requires the use of specific modules and I/O terminal blocks:
I/O modules having catalog number suffix J or above. These modules have a projecting
alignment tab that fits into a corresponding alignment tab on I/O Terminal Blocks listed below.
Note that modules with this tab can also be installed on older I/O Terminal Blocks that do not
have mating alignment tabs. However, Hot Insertion/Removal are not supported in such an
installation.
I/O Terminal Blocks IC670CHS101, 102, or 103. These I/O Terminal Blocks have projecting
alignment tabs designed to facilitate Hot Insertion/Removal of modules. Modules that are
earlier than revision J cannot be mounted on these terminal blocks.
I/O Terminal Blocks IC670CHS001, 002, and 003, which lack alignment tabs, do not support
Hot Insertion/Removal of modules. With these terminal blocks, I/O Station power should be
off when installing or removing modules.
Mixing IC670CHS10x terminal blocks with IC670CHS00x terminal blocks in the same I/O
station is not recommended.
