Do the system configuration of mixture of CC-Link IE
TSN Class B/A and "TSN HUB Setting" in "Connection
Device Information" under "Basic Settings" differ?
Is the event code 00C72 registered in the event history
of the master station?
When the station is connected in line topology, is the communication speed setting
matched among stations?
Is there any reason on the device station side why cyclic communication is not
performed?
Is the event code 00C44 registered in the event history?
Is a device number outside the setting range set for a link side device in "Refresh
Setting"?
When "Communication Speed" of the master station is 1 Gbps, does the cyclic data
size exceed 2K bytes in total for all device stations on the 100 Mbps device side at
the boundary between a 1 Gbps CC-Link IE TSN Class B device except for the
master station and 100 Mbps CC-Link IE TSN Class B device?
■For firmware version "1.001" or earlier
When the communication speed of the master station and CC-Link IE TSN Class A
device station each are 1 Gbps, is "Communication Period Setting" of the CC-Link IE
TSN Class A device station set to "Basic Period" or "Normal Speed"?
If the above actions do not solve the problem, perform the following tests to check for an error.

Take the following action for the device station with the IP address
displayed in the detailed information of the event history.
• Update the firmware of the device stations to the latest version.
Correct "Communication Speed" under "Application Settings" so that
the communication speed is matched for each station.
• Check if an error has occurred on the device station.
• Check if the device station settings and parameters are correct.
• Refer to the manual of the device station for troubleshooting.

device station parameter automatic setting target station.
Check that the device numbers of RX and RWr set in "Refresh Setting"
are within the applicable range.
• Restrict the number of connected stations so that the cyclic data size
of 100 Mbps devices does not exceed 2K bytes in total.
• Connect 100 Mbps device to the master station.
• Update the firmware version of the master station to "1.002" or later.
• For the values set for "Communication Period Interval Setting" and
"Cyclic Transmission Time" each in "Communication Period Setting"
under "Basic Settings", set a value not smaller than the minimum
value for the communication cycle interval (cyclic data transfer
processing time). Page 201 Communication cycle intervals
