NDCU-12C數(shù)字量輸入輸出模塊,NDCU-12C卡件
總線接口單元NDCU-12C 或更高版本支持熱插拔
輸入/輸出站中的模塊數(shù)量。
熱插入/移除意味著可以在I/O站通電時移除和更換模塊
在不影響B(tài)IU或輸入/輸出站中的其他模塊的情況下應(yīng)用。獨立輸入/輸出模塊
必須關(guān)閉插入或卸下模塊的電源。

熱插拔需要使用特定模塊和輸入/輸出接線板:
?具有目錄號后綴J或以上的輸入/輸出模塊。這些模塊有一個
與下面列出的輸入/輸出端子上的相應(yīng)對齊選項卡相匹配的對齊選項卡。
請注意,帶有此選項卡的模塊也可以安裝在沒有NDCU-12C數(shù)字量輸入輸出模塊
具有匹配的對齊卡舌。但是,在這種情況下不支持熱插入/移除
安裝
?輸入/輸出接線板IC670CHS101、102或103。這些輸入/輸出接線板具有突出的
對齊卡舌設(shè)計用于方便熱插入/移除模塊。以下模塊
這些接線板上不能安裝J版之前的產(chǎn)品。
輸入/輸出接線板IC670CHS001、002和003沒有對齊卡舌,不支持
模塊的熱插拔。使用這些接線板,輸入/輸出站電源應(yīng)
安裝或卸下模塊時關(guān)閉。
在同一輸入/輸出中混合IC670CHS10x接線板和IC670CHS00x接線板
不建議使用站點。
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.
