When "Connection
Device Information"
under "Basic Settings"
of the master station is
set to "Mixture of CC-
Link IE TSN Class B/A
or CC-Link IE TSN
Class A Only"
If the stations are connected in a line topology, do "Communication Speed" for
the stations match one another?
Is there any reason why cyclic transmission cannot be performed on the slave
station side?
Is the event code 00C44 registered in the event history?
In multicast mode, are a local station and a CC-Link IE TSN Class A remote
station connected on the end side via a switching hub?
Is the minimum value for communication cycle interval set to both
"Communication Period Interval Setting" and "Cyclic Transmission Time" in
"Communication Period Setting" under "Basic Settings" of the module
parameter?
In multicast mode, has an external device sent a frame to a station before data
link establishment of all stations?
When "Communication Speed" of the master station is 1Gbps, does the cyclic
data size exceed 2K bytes in total for all slave stations on the CC-Link IE TSN
Class B device side with the communication speed 100Mbps at the boundary
between CC-Link IE TSN Class B devices with a communication speed of
1Gbps (other than the master station) and CC-Link IE TSN Class B devices
with a communication speed of 100Mbps?
Is the slave station connected to P2?
If the above actions do not solve the problem, perform the following tests to check for an error.
• Module communication test ( Page 371 Module Communication Test)
• Communication test ( Page 382 Communication Test)
Station is disconnected from the network
The following is the action to be taken when a station in data link is disconnected.

Is the ambient temperature for the module outside the specified range?
If the above action does not solve the problem, perform the following tests to check for an error.
• Module communication test ( Page 371 Module Communication Test)

18.1 Troubleshooting Related to CC-Link IE TSN
Is the event code 00C72 registered in the event
history?
■For firmware version "01"
Is a CC-Link IE TSN Class A device that supports
the CANopen profile with the protocol version 2.0
connected?
Action
• Update the version of the engineering tool to the latest version.
• Update the firmware of the slave station with the IP address displayed in the
detailed information of the event history to the latest version.
Update the firmware version of the master station to "02" or later.
Correct "Communication Speed" under "Application Settings" for the stations
so that the communication speeds match one another.
• Check if an error has occurred on the slave station.
• Check if the slave station settings and parameters are correct.
• Refer to the manual of the slave station for troubleshooting.
Match the communication speed of the master station to the communication
speed of the station for which the slave station parameter automatic setting is
to be configured.
• Configure settings with the switching hub so that the multicast frame (with
multicast MAC address 09:00:70:00:10:02 and 09:00:70:00:10:05) will not
be transferred to the port of the CC-Link IE TSN Class A remote station.
• Check the connected device and do not connect both a local station and a
CC-Link IE TSN Class A remote station on the end side of the switching
hub.
• Set unicast mode.
Set "Cyclic Transmission Time" to a value obtained by the following formula:
Minimum value of cyclic transmission time + Greatest value among the two
values shown below.
• 10% of the calculated minimum cyclic transmission time
• When the communication speed for the master station is set to 1Gbps: The
number of slave stations  2s
• When the communication speed for the master station is set to 100Mbps:
The number of slave stations  20s
Ensure that the external device will not send a frame before data link
establishment of all stations, then reset the master station.
• Restrict the number of the connected stations so that the cyclic data size of
the devices with communication speed of 100Mbps does not exceed 2K
bytes in total.
• Connect the device with communication speed of 100Mbps to the master
station.
Connect the slave station to P1.
Action
Keep the ambient temperature within the specified range by taking action
such as removing heat source.
