(4) When the D LINK LED flashes
Does the bridge module station number match the station
number of the bridge module specified in the network
configuration settings of the master station?
Is the station type an intelligent device station?
Is the station type a reserved station?
Has data link been found stopped through the CC-Link IE
Field Network diagnostics?
Is the station number setting switch set to other than 1 to
120?
(5) When the D LINK LED turns off
Does the own station on the network operate normally?
Are 1000BASE-T-compliant Ethernet cables used?
Is the distance between stations connected to each other
with an Ethernet cable 100m or less?
Does the cabling condition (bend radius) meet the
specifications?
Is any Ethernet cable disconnected?
Do other stations connected to the bridge module operate
normally?
Does the switching hub operate normally?
Is the station number of the bridge module same as that of
another station?

Corrective action
Match the bridge module station number and the station
number specified in the network configuration settings of the
master station.
Change the station type of the module to an intelligent device
station in the network configuration settings of the master
station.
Change the setting of reserved/ignored error station to other
than the reserved station in the network configuration
settings of the master station.
Check the link status through the CC-Link IE Field Network
diagnostics and start link if it is stopped.
The setting range for the station number setting switch is 1 to
120. Set the number between 1 to 120.
Corrective action
Connect the engineering tool to the master station, and
check that the master station is performing data link with the
CC-Link IE Field Network diagnostics. ( User's manual
for the master/local module used)
Replace the cable with a 1000BASE-T-compliant Ethernet
cable. ( User's manual for the master/local module used)
Change the length of the Ethernet cable between stations to
100m or less.
Refer to the manual for the Ethernet cable used, and correct
the bend radius.
Replace the Ethernet cable.
Check that other stations have been powered on.
• Check that a 1000BASE-T-compliant switching hub is
used. ( User's manual for the master/local module
used)
• Check that the switching hub has been powered on.
The same station number is used for two or more stations.
Change the setting so that all the stations have their unique
numbers.
