Table 45. PROFINET IO Interface, CI871 - Indications and Fault Finding
Fault Possible Cause and Corrective Action
Neither R(un) nor F(ault) LEDs are
ON
The CI871 unit is in the process of
configuration. If the condition persist, and
no other unit LED on the CEX-Bus is ON:
• Check that a valid hardware
configuration including the CI871 is
downloaded to the controller.
• Check the CEX-Bus fuse inside the
PM8xx processor unit.
• Initiate a reset signal (INIT) from the
PM8xx processor unit.
• Replace the CI871 unit.
F(ault) LED is ON The CI871 unit is in the process of being
restarted. Wait until the restart operation is
complete.
Replace unit if the condition persists.
RxTx1/RxTx2 LED is OFF Reception and transmission of I/O data
does not occur at the respective Ethernet
channels.
RxTx1/RxTx2 LED is flashing Reception and transmission of I/O data
occurs normally at the respective Ethernet
channels.
PRIM is OFF The CI871 is not started by the application.
PRIM is ON The CI871 is started by the application.
DUAL is OFF Default, as no redundancy is supported with
PROFINET IO.
 CI871 supports hot swap.

MOD5 Interface - CI872
Table 46 provides the indications and possible causes, and the corrective actions for
the faults, appearing in the MOD5 communication interface, type - CI872.
Table 46. MOD5 Communication Interface, Type CI872 - Indications and Fault Finding
Indication Possible Causes, and Corrective Actions (for faults)
Both R(un) and F(ault)
LED's are OFF
Possible Cause 1: The CI872 module is connected to the
controller and the configuration is not downloaded to the
controller for that position.
Corrective Action 1: Ensure that the CI872 module is
configured in the Hardware Tree (in the Control Builder) for
that position, and that the configuration is downloaded to
controller.
Possible Cause 2: The CI872 module is just powered up or
it is being configured and downloaded.
Corrective Action 2: Allow time for the module to initialize.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then one of the
following corrective actions is recommended:
• Remove and insert the CI872 module to the CEX-Bus
and allow time for it to initialize.
• If the CEX-Bus already contains other communication
modules and all the LED's on those modules are OFF,
or if this CI872 is the only module on the CEX-Bus,
then check the CEX-Bus fuse inside the PM86x
Processor Unit.
Corrective Action 4: If the indication still persists after
performing the corrective actions 1 to 3, replace the CI872
module.
Section 5 Maintenance MOD5 Interface - CI872
3BSE036351-510 A 233
F(ault) LED is ON Possible Cause 1: The CI872 module is in the process of
upgrading the firmware (if the upgrade is in progress).
Corrective Action 1: Wait for the firmware to be upgraded.
Possible Cause 2: Fault in the CI872 module.
Corrective Action 2: Hot remove and hot insert the CI872
module.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then replace the
CI872 module.
R(un) LED is ON The green R(un) LED indicates that CI872 is operational.
Rx/Tx1, Rx/Tx2, and
Rx/Tx3 LEDs are flashing
There is one LED corresponding to each port on the CI872
module. When the LED corresponding to a port flashes, it
indicates that communication is happening on that particular
port.
Rx/Tx1, Rx/Tx2, Rx/Tx3
LED is OFF
Possible Cause 1: The fiber optic cable is not connected or
it is not connected properly to the port.
Corrective action 1: Do any of the following:
• Check the corresponding optical cable connections,
that is, the connections for reversed transmitter and
receiver optical cables for that particular port, and the
connections on the DOW MOD5 controller.
• Check the Network Controller Board (NCB) on the
MOD5 Controller connected to that particular port.
Possible Cause 2: The configuration is not downloaded
from the Hardware Tree (in the Control Builder) to the
controller.
Corrective Action 2: Ensure that the module is configured
in the Hardware Tree for the correct position and the
configuration is downloaded to controller.

DUAL LED is ON 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 initi
