当CI872
模块以冗余配置运行。模块
双LED是否亮起？是否为主要[激活]
模块处于冗余配置。
注：即使备份CI872模块运行时出现错误或
冗余配置失败，双LED仍亮起
冗余配置的主CI872模块。
当出现以下任一情况时，双LED熄灭：黄色双LED熄灭：
满足以下条件：
•CI872以单一配置运行。
•CI872在冗余配置中运行，但它作为
备份模块。
所有LED均关闭可能原因1：CI872在
硬件树（在控件生成器中）与
CEX总线上的CI872位置。
纠正措施1：检查并纠正
硬件树中的CI872模块符合
CEX总线上的位置，反之亦然。
可能原因2：CI872模块热插入，并且
配置不会下载到控制器。
纠正措施2：确保模块已配置
在硬件树中（在控件生成器中）
位置，并将配置下载到
控制器。
可能原因3：CI872刚刚热插拔，它处于
配置过程。
纠正措施3：为模块初始化留出时间。

可能原因1：MTMConnect和/或MTMReadCyc
和/或MTMDefCyc被禁用。
纠正措施1：启用MTMConnect、MTMReadCyc，
以及MTMDefCyc功能块。
可能原因2：MTMConnect和/或MTMReadCyc
和/或MTMDefCyc功能块显示坏状态。
纠正措施2：检查不良状态的原因
（请参阅联机帮助中的MTMCommLib状态代码），
并针对不良状态采取适当的纠正措施。
可能原因3：中通道参数的值
MTMConnect功能块不符合
CI872模块在硬件树中的位置。
纠正措施3：确保信道的值
功能块中的参数符合
CI872模块在硬件树中的位置。
纠正措施4：即使在
执行纠正措施1至3，然后热移除和
在CEX总线上热插入CI872模块，并留出时间
用于模块初始化。
如果纠正措施是更换有故障的CI872模块，则更换为
另一个CI872模块具有相同版本的硬件和固件。
CI872支持热插拔。

CEX总线上没有其他单元指示灯
关于：
•检查内部的CEX总线保险丝
PM8xx处理器单元。
•从以下位置启动复位信号（INIT）：

The yellow DUAL LED is illuminated when the CI872
module is run in redundant configuration. The module that
has the DUAL LED illuminated is the primary [active]
module in a redundant configuration.
Note: Even if the backup CI872 module runs with errors or
fails in redundant configuration, the DUAL LED is still ON in
primary CI872 module in redundant configuration.
DUAL LED is OFF The yellow DUAL LED is OFF when any of the following
conditions are met:
• CI872 is run in single configuration.
• CI872 is run in redundant configuration, but it acts as a
backup module.
All LED's are OFF Possible Cause 1: Difference in the CI872 position in the
Hardware Tree (in the Control Builder) as compared to the
CI872 position on the CEX-Bus.
Corrective Action 1: Check and correct the position of
CI872 module in the Hardware Tree in accordance with the
position on CEX-Bus, or vice-versa.
Possible Cause 2: The CI872 module is hot inserted and
the configuration is not downloaded to the controller.
Corrective Action 2: Ensure that the module is configured
in the Hardware Tree (in the Control Builder) for that
position, and that the configuration is downloaded to
controller.
Possible Cause 3: The CI872 is just hot inserted and it is in
the process of configuration.
Corrective Action 3: Allow time for the module to initialize.

Rx/Tx LED's are flashing,
but there is no
communication
Possible Cause 1: MTMConnect and/or MTMReadCyc
and/or MTMDefCyc are disabled.
Corrective Action 1: Enable MTMConnect, MTMReadCyc,
and MTMDefCyc function blocks.
Possible Cause 2: MTMConnect and/or MTMReadCyc
and/or MTMDefCyc function blocks show a bad status.
Corrective Action 2: Check the reason for the bad status
(see the status codes for MTMCommLib in the Online Help),
and take the appropriate corrective action for the bad status.
Possible Cause 3: The value for the Channel parameter in
the MTMConnect function block is not in accordance with
the position of the CI872 module in the Hardware Tree.
Corrective Action 3: Ensure that the value of the Channel
parameter in the function block is in accordance with the
position of the CI872 module in the Hardware Tree.
Corrective Action 4: If the condition persists even after
performing corrective actions 1 to 3, then hot remove and
hot insert the CI872 module on the CEX-Bus and allow time
for the module to initialize.
If the corrective action is to replace the faulty CI872 module, replace it with
another CI872 module which has the same version of hardware and firmware.
CI872 supports hot swap.

Neither R(un) nor F(ault) LEDs are ON The CI873 unit is in the process of being
configured. Wait until the configuration
is complete. If the condition persist, and
no other unit LED on the CEX-Bus is
ON:
• Check the CEX-Bus fuse inside the
PM8xx processor unit.
• Initiate a reset signal (INIT) from
the PM8xx processor unit.
• Replace the CI873 unit.
F(ault) LED is ON The CI873 unit is in the process of being
restarted. Wait until the restart operation
is complete.
