Indicates the status of CC-Link.
Indicates the operating status of the bridge module.
RUN LED (green)
ON: Operating normally
OFF: A hardware failure or watchdog timer error has occurred.
Indicates the data link status.
L RUN LED (green)
ON: Performing data link
OFF: Not performing data link
Indicates whether the module is sending data.
SD LED (green)
ON: Sending data
OFF: Not sending data
Indicates whether the module is receiving data.
RD LED (green)
ON: Receiving data
OFF: Not receiving data
Indicates whether the bridge module is operating as a CC-Link master station.
MST LED (green)
ON: Operating as a CC-Link master station.
Flashing: Line test or unit test is being executed.
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.
ERR. LED (red)
• 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
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.
L ERR. LED (red)
(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
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.
Sets how to read the CC-Link parameters at the startup. ( Page 55, Section 7.2)
Starts up CC-Link by the automatic CC-Link startup, and starts the data refresh after the module is
powered on or reset.
AUTO
When the switch is changed from PRM to AUTO, CC-Link also starts up by the automatic CC-Link
startup.
Generates CC-Link parameters from the station information of the connected CC-Link remote
station and stores the data in the flash ROM.
SET
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.
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.
PRM
When CC-Link parameter setting using the engineering tool is used, set the switch to PRM. (
