FIP sindle rack冗余系統(tǒng)中各單元之間的物理連接總共可以有3英尺（0.9米）的互連電纜。FIP單機(jī)架冗余系統(tǒng)的CPU可以是IC697CFR782或IC697CFR28。模塊在冗余機(jī)架中占用一個(gè)插槽，并有兩個(gè)連接器，頂部連接器用于連接到其他機(jī)架部分中的總線變送器模塊。底部連接器未使用。五個(gè)綠色LED提供RCM模塊運(yùn)行狀況的狀態(tài)指示，并監(jiān)控?zé)醾溆肅PU冗余系統(tǒng)的控制狀態(tài)。這些LED標(biāo)記為BOARD OK、LOCAL READY、LOCAL ACTIVE、REMOTE READY和REMOTE ACTIVE。本地是指RCM所在的系統(tǒng)；遠(yuǎn)程是通過擴(kuò)展總線連接的另一個(gè)系統(tǒng)。模塊上的一個(gè)按鈕允許您手動將控制從激活切換到備用單元（如果備用單元已準(zhǔn)備就緒），從而允許在系統(tǒng)在線時(shí)維護(hù)先前激活的單元。必須使用MS DOSr或Windowsr編程軟件配置功能將RCM配置到FIP冗余系統(tǒng)中。KSD211B控制卡

Functions
This
Redundancy
Communications
Module
(RCM)
provides
a
path for a synchronizing message from the active to the backup
unit which is used to synchronize the two CPUs in a FIP single
rack redundancy system. It also provides the
path for the
transfer of shared I/O data between the two units.
The physical
connection between
units in a
FIP
sindle
rack redundancy
system can have
up
to 3
feet
(0.9
meters) total of
interconnecting cable.
The CPUs for
FIP single rack
Redundancy systems
can be either IC697CFR782 or
IC697CFR28.
The module occupies a single slot in a redundant rack and
hastwo connectors, the top connector isfor attachment to the
Bus Transmitter Module in the other rack section. and the
bottom connector is unused.
Five green LEDs provide status indication of the health of the
RCM module and monitor the controlstatus ofthe Hot Standby
CPU Redundancy system. These LEDS are labeled BOARD
OK, LOCAL READY, LOCAL ACTIVE, REMOTE READY, and
REMOTE ACTIVE. Local refers to the system that the RCM
is in; remote is the other system connected through the
expansion bus
A pushbutton on the module allows you to manually switch
control from the active to the backup unit (if the backup unit
is ready) which allows maintenance of the previously active
unit while the system is on-line.
The RCM must be configured into the FIP redundancy
system using the MS-DOSr or Windowsr programming
software configuration function.
