4) CC-Link LED
 Indicates the status of CC-Link.
RUN LED (green)
Indicates the operating status of the bridge module.
ON: Operating normally
OFF: A hardware failure or watchdog timer error has occurred.
L RUN LED (green)
Indicates the data link status.
ON: Performing data link
OFF: Not performing data link
SD LED (green)
Indicates whether the module is sending data.
ON: Sending data
OFF: Not sending data
RD LED (green)
Indicates whether the module is receiving data.
ON: Receiving data
OFF: Not receiving data
MST LED (green)
Indicates whether the bridge module is operating as a CC-Link master station.
ON: Operating as a CC-Link master station.
Flashing: Line test or unit test is being executed.
ERR. LED (red)
Indicates the error status of CC-Link of the bridge module.
ON: Any of the following errors has occurred.
• An error has been detected in all the stations.
• The transmission speed/mode setting switch of the bridge module is out of the setting range.
• Two or more CC-Link master stations are connected on the same line.
• The CC-Link parameters have not been set correctly.
• The cable is disconnected. Or the transmission path has been affected by noise or other
factors.
Flashing: A faulty station has been detected in the data link. Or the same station number is used
for multiple CC-Link remote stations.
OFF: Operating normally
L ERR. LED (red)
Indicates the data link error of CC-Link of the bridge module.
ON: A data link error has occurred at the own station.
Flashing at regular intervals: The setting of the transmission speed/mode setting switch was
changed when the power of the module was on.
(Note that the change of the switch may not be detected when all stations are faulty.)
Flashing at irregular intervals: The communications are unstable due to the following reasons.
• A terminating resistor is not connected.
• The bridge module or CC-Link dedicated cable has been affected by noise.
OFF: Operating normally
5) Station number setting switch
A rotary switch used for the following setting and test.
• Station number setting (  Page 37, Section 6.1.1)
• Unit test (  Page 101, Section 9.8)
To set the station number setting switch, use a flathead screwdriver having a tipped width of
3.5mm or less.
6) Startup mode switch
 Sets how to read the CC-Link parameters at the startup. (  Page 55, Section 7.2)
AUTO
Starts up CC-Link by the automatic CC-Link startup, and starts the data refresh after the module is
powered on or reset.
When the switch is changed from PRM to AUTO, CC-Link also starts up by the automatic CC-Link
startup.
SET
Generates CC-Link parameters from the station information of the connected CC-Link remote
station and stores the data in the flash ROM.
Writing to the flash ROM is not executed if a parameter-related error has occurred.
When the switch is changed from SET to AUTO, the data refresh starts by the automatic CC-Link
startup.
PRM
Reads the CC-Link parameters from the flash ROM to start up CC-Link and starts the data refresh
when the module is powered on or the switch is changed from AUTO to PRM.
When CC-Link parameter setting using the engineering tool is used, set the switch to PRM. (
