Change the setting so that all the station numbers differ.
Check item
Action
Does the set station number of the main D/A converter module match
the station number of the main D/A converter module that is set up in
the network configuration settings of the master station or in the CC
IE Field configuration?

Is stop of the data link checked through CC-Link IE Field Network
diagnostics?
Check the link status through CC-Link IE Field Network diagnostics and start the link
when the data link is stopped.
Is the station number switch set to other than 1 to 120?
The setting range for the station number switch is 1 to 120. Set the number from 1 to
120.
Has the connection been changed to the other master station with a
different network number?
• Correct the connection to the previous master station.
• To communicate with the master station with a different network number, power off
and on the main D/A converter module.
