When "Connected 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"
In the case of line topology, do the communication speed settings of each station
match?
Is there any reason why cyclic transmission cannot be performed on the device
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 the "Communication
Period Interval Setting" 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 the communication speed setting of the master station is set to 1 Gbps, is the
total cyclic data size of all device stations on the 100 Mbps device side at the
boundary between CC-Link IE TSN Class B 1 Gbps devices other than the master
station and CC-Link IE TSN Class B 100 Mbps devices exceeding 2K bytes?
Is the communication route for dynamic routing decided?
Does the relay station of the communication route support dynamic routing?
If the above actions do not solve the problem, perform the following tests to check for an error.

4.4 Troubleshooting by Symptom
Is the event code 00C72 registered in the event
history?
■When the version of Add-on baseSystem is
"1.20 to 1.22"
Is a CC-Link IE TSN Class A device that
supports the CANopen profile with the protocol
version 2.0 connected?
Action
• Update the engineering tool to the latest version.
• Update the device station firmware with IP address displayed in the
detailed information of the event history to the latest version.
Update the master station firmware to Add-on baseSystem version
"1.24" or later.
Check and correct the settings on the communication speed of each
station. For the setting method of the communication speed, refer to the
manual for each device.
• 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.
Match the communication speed of the master station to the
communication speed of the station for which the device 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 a value obtained by adding 10% to the minimum value for cyclic
transmission time for each setting.
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 stations to be connected so that the total cyclic
data size of 100 Mbps devices does not exceed 2K bytes.
• Connect 100 Mbps devices to the master station.
• After turning the power supply ON, start transient transmission after a
small amount time has elapsed.
• When the "Dynamic Routing" setting for the station of the
communication route is set to "Disable", set it to "Enable".
When there is a relay station that does not support dynamic routing, set
the "Routing Setting" of "CPU Parameter" to all stations of the
communication route.
Action
Check the connected device and reduce the maximum number of connectable
stations to 31 stations (master station: 1, device station: 30) or less.
• Check the connected device and do not connect the CC-Link IE TSN Class
A devices in line topology.
• When connecting the CC-Link IE TSN Class B device and CC-Link IE TSN
Class A device, connect them via a general-purpose hub.
Check the connected device, and, if the master station is connected in line
topology, only connect CC-Link IE TSN Class B devices.
Check the connected device, and if connecting the master station and a CC-
Link IE TSN Class A device, connect them with a general-purpose hub.
Check the connected devices, and connect only one CC-Link IE TSN Class A
device to each port of a general-purpose hub.
Check the connected device and do not connect a CC-Link IE TSN Class A
device and a standard Ethernet device.
