Does the cabling condition (bending radius) meet the
specifications?
Is any Ethernet cable disconnected?
Is the network configured in the ring topology?
Has the time synchronization source station been reset?
Is the time synchronization source station turned off?
Is the time synchronization source station operating normally?
Has any other station been reset?
Are other stations turned off?
Are other stations connected to the Motion module operating
normally?
Is the IP address of another station set?
Are other stations set in the network configuration of the master
station?
Is a type of wiring described in the restrictions in the wiring
specifications mistakenly performed?
Are station numbers unique?
Is the IP address duplicated with another station?
Is the number of device stations connected exceeded the
maximum number of connectable stations?
Do CC-Link IE TSN devices and Ethernet devices coexist?
Does the IP filter setting mistakenly block communications from
the IP address of another station?
Are time synchronization devices with time synchronization
priority of 0 to 15 connected?
Is the connected TSN switching hub operating normally?
Action
• Use a switching hub that conforms to the standard. ( Page 20 Performance
Specifications of CC-Link IE TSN)
• Power off and on the switching hub.
Set the station-to-station distance within range. ( Page 20 Performance Specifications
of CC-Link IE TSN)
Refer to the manual for the Ethernet cable, and correct the bending radius.
Replace the Ethernet cable.
Configure the network to avoid the ring topology.
• Since a station is temporarily disconnected after switching the time synchronization
source, wait for it to return.
• Avoid unnecessary disconnections or returns in a station that is the time synchronization
source.
Take action by referring to the manual for the time synchronization device.
• Avoid unnecessary reset since a station is disconnected while resetting.
• Start other stations.
Power on other stations.
Execute the CC-Link IE TSN/CC-Link IE Field diagnostics from the master station to
identify the faulty module of another station. After identification, take action by referring to
the manual for the relevant module.
Set an IP address to a device station with no IP address setting.
Set connected device stations in the network configuration of the master station.
Correct the wiring. For details, refer to "WIRING" in the following manual.
MELSEC iQ-F FX5 Motion Module/Simple Motion Module User's Manual (Startup)
Change the duplicated station number.
Change the IP address of the duplicated station.
Make sure that the number of device stations connected is within the maximum number of
connectable stations specified in the CC-Link IE TSN performance specifications.

Correct the wiring. For details, refer to "WIRING" in the following manual.
MELSEC iQ-F FX5 Motion Module/Simple Motion Module User's Manual (Startup)
Change the IP filter setting parameter to allow communication for the IP address of
another station.
Remove time synchronization devices with time synchronization priority of 0 to 15, or
change the priority to between 16 and 255.
 Manual for the time synchronization devices used
Power off and on the TSN switching hub.
Check the TSN switching hub parameters and correct the settings. For the setting method,
refer to the manual for the TSN switching hub.
The main check items are as follows:
• Enable each port of the TSN switching hub.
• Set the communication speed and port type to Auto.
• Match the settings for the time synchronization and communication period of the TSN
switching hub to those of the master station.
• Match the VLAN setting of the master station to that of the device stations.
