Action
Connect the engineering tool to the master station, and then check if a data link is
established in the own station by using 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 station-to-station distance to 100m or less.
Refer to the manual for the Ethernet cable used, and correct the bend radius.
Replace the Ethernet cable.
Check if the power supplies of the other stations are turned on.
• Check if a 1000BASE-T-compliant switching hub is used.
 User's manual for the master/local module used
• Check if the power supply of the switching hub is turned on.
Two or more stations are overlapping.
Change the setting so that all the station numbers differ.
Action
Match the station number of the D/A converter module with the station number that is
set up in the network configuration settings of the master station or in the CC IE Field
configuration.
In the network configuration settings of the master station, change the station type of
the module to the remote device station.
Change the setting of reserved/invalid error station to other than the reserved station
in the network configuration settings of the master station.
Check the link status through CC-Link IE Field Network diagnostics and start the link
when the data link is stopped.
The setting range for the station number setting switch is 1 to 120. Set a number from
1 to 120.
• Correct the connection to the previous master station.
• To communicate with a master station with a different network number, power off
and on the D/A converter module.
Action
• Check if 1000BASE-T-compliant Ethernet cables are used.
 User's manual for the master/local module used
• Check if the station-to-station distance is 100m or less.
• Check if the Ethernet cables are not disconnected.
• Check if a 1000BASE-T-compliant switching hub is used.
 User's manual for the master/local module used
• Check if the power supply of the switching hub is turned on.
